API: wbcreateclaim including wbsetreference

Hi! Can anybody give me an URL example how to create a claim including setting its reference (P143)? I am missing an example here:

I don't want to edit a statement in two steps if a claim and its reference could be edited in one step instead. But I don't know the URL for this combination.

Thank you, Doc Taxon (talk) 22:32, 5 August 2017 (UTC)

AFAIK not possible with wbcreateclaim and wbsetreference. You would instead read the item in JSON representation, modify the JSON object and send it back to the server as the data parameter with wbeditentity. (disclaimer: API beginner here.) —MisterSynergy (talk) 22:45, 5 August 2017 (UTC)
@MisterSynergy: as far as I have heard it should be possible with wbsetclaim, but I cannot find the correct API URL. So please give me an example how to proceed as stated above. I have tried your proposal with wbeditentity, but it doesn't work this way. Thank you, Doc Taxon (talk) 23:45, 5 August 2017 (UTC)
@Doc Taxon: I only have an example in Python (pywikibot), see this PAWS notebook. Therein, functions compileSourceJSON() and compileClaim() are worth to look at, and the lines before and including Qitem.editEntity() (which uses wbeditentity). As you can probably see in the code, I also tried to work with the other two API calls, but I did not get that running. —MisterSynergy (talk) 05:45, 6 August 2017 (UTC)

@MisterSynergy: Here a specific JSON example:


But this example gives the error:

error {code modification-failed info {Data value corrupt: $data must be an array} messages {{name wikibase-validator-bad-value parameters {{$data must be an array}} html {* {Data value corrupt: $data must be an array}}}} * {See for API usage. Subscribe to the mediawiki-api-announce mailing list at <> for notice of API deprecations and breaking changes.}} servedby mw1205

How could I fix it? Doc Taxon (talk) 13:24, 6 August 2017 (UTC)

I have never seen that message, and I can’t find relevant docs right now. Will try to look at it later this day, maybe others can help as well. —MisterSynergy (talk) 14:57, 6 August 2017 (UTC)
The part "value":"Q48183" should be "value": {"entity-type": "item","numeric-id": 48183, "id": "Q48183"},. Mbch331 (talk) 15:54, 6 August 2017 (UTC)
@Mbch331: Wow, that's it! Why didn't I find this solution myself, though I used this part in the first snak of the statement? Thank you very much indeed, Doc Taxon (talk) 16:27, 6 August 2017 (UTC)

Che Guevara's travel diary

Is residence (P551) the best property to state where a traveler lived for some days? I am thinking about adding the The Motorcycle Diaries (Q1769105) route to Che Guevara (Q5809) item, but I wanted to ask first. Emijrp (talk) 15:42, 31 July 2017 (UTC)

Please use point in time or date qualifiers together with 551.
visit travel result in no specific properties at the moment. d1g (talk) 17:32, 31 July 2017 (UTC)
Yes, I was going to add start time (P580) and end time (P582). Is there any property for "official visits"? Che was a minister in Cuba and he visited some countries. Emijrp (talk) 20:40, 31 July 2017 (UTC)

Performance problems and their effect on our community

Hoi, I am staggered to learn that people think it appropriate to say that someone is "asocial" because he is running a bot as he always did. It is not a Wikidata problem as the backlog is the consequence of a design choice at the MediaWiki end. The problem needs to be fixed at that end as well.

Wikidata as a datasource is immature and it needs a lot more work before it will function properly to fill data in info boxes on the scale of all Wikipedias. There has not been a study to the effectiveness of posting Wikidata changes and at the same time much of the data entered in Wikidata is from Wikipedias. There are no consolidation processes available between Wikidata and the Wikipedias so we can surely do without our changes in Wikipedia but we cannot do without adding more data to Wikidata.

In consequence, running a bot is not asocial and blocking a bot operator and using such accusations has a severe negative effect on our community. There is no planning for a fix for this problem and we should therefore just dismiss this as a Wikipedia problem that the Wikipedia engineers have to fix. Thanks, GerardM (talk) 16:19, 29 July 2017 (UTC)

I think that naming him "asocial" was due to poor English skills to find a better and nice word. The bot was adding wrong labels, so I think that the block was OK. About the performance, I think Wikidata developers/sysops must fix the problem ASAP or Wikidata will die from success. Emijrp (talk) 16:52, 29 July 2017 (UTC)
It was more about the editing speed, 155 edits per minute is too much. Operators of Wikimedia servers have complained last year about such edit rates. Sjoerd de Bruin (talk) 17:17, 29 July 2017 (UTC)
We should publish more information (without too many words): acceptable rate, most plausible period when to run scripts in huge bulk.
Perhaps special page for "our servers are slow right now" status (machine-readable red flag for mass edits).
But we shouldn't bite people when they just learn new things for the first time or acknowledge their mistakes. d1g (talk) 17:31, 29 July 2017 (UTC)
We have Wikidata:Bots#Bot requirements, but we failed to establish rules for QuickStatements (Q20084080) users or similar mass editing tools. --Succu (talk) 21:38, 29 July 2017 (UTC)
The tech needs to be able to handle way more than 155 edits per minute. At that rate, there will only be 2.7 edits per item per year across our current knowledge base. Since every item needs descriptions in hundreds of languages (and plenty of other properties), then I think that is too slow (even though many descriptions can be done in one edit). I agree that engineers should turn their attention to this asap. --99of9 (talk) 02:35, 30 July 2017 (UTC)
NO! It is more important that we have good well sourced statements in every item. If the label is unique, a description does not look essential at all. We have fallback, why do we need descriptions in hundreds of languages for Flen (Q2022586), when we have one in English? -- Innocent bystander (talk) 07:08, 30 July 2017 (UTC)
Er, I never said that statements weren't important. I used labels only to show that the scale of the whole mission is larger than 2.7 edits per year. I speak English, so one is fine for me, but I would like participation from the non-English world. --99of9 (talk) 03:38, 1 August 2017 (UTC)
Why? Because we are a multilingual project. This is out of discussion. Emijrp (talk) 07:04, 1 August 2017 (UTC)
First, labels are not unique and do not need to be unique. Second, because of statements there is a difference between items. Third, we do not need descriptions in any language when descriptions are generated automatically. This provides a better solution for the 280+ languages we aim to support. Thanks, GerardM (talk) 09:18, 1 August 2017 (UTC)
As said before, my RPi is now shut down, and will not do any edits on descriptions anymore, as I learned that our server park is designed for manual update speed only. This means we should from now on rely on manually adding descriptions to items, else the update processes that feed the other tools are interrogated. It appears to me that it seems to be more important that these other tools get their information in time, although I do not see why my bot was causing this, as it was not doing any edits for the last four weeks due to my holidays. And blocking my bot and calling me names, as a first means of communication is what is my interpretation as asocial. I have never been aware of any technical issues, and I'm also not sure if my bot was really any cause of these issues, but others seem to be very sure that I am the root cause of all problems in this world, and I start to feel like it is that some people need someone to blame, instead of a solution. But when I'm not around anymore I can at least not be blamed no more. I sincerely hope for all of you that I was indeed the root cause of all issues, because they will now be solved for once and for all. Edoderoo (talk)
"but others seem to be very sure that I am the root cause of..." GerardM said something different. Anyway it isn't something we should spend time on discussions. d1g (talk) 08:19, 30 July 2017 (UTC)
Blocking bots is a very common thing when they are causing trouble (generating lag, malfunctioning, etc). The first link in {{Bot}} is for blocking, not a surprise. My own bot has been blocked before for fast editing (I was contacted to reduce speed, but it was midnight in Europe and I was sleeping). It isn't a big deal. Let's calm down the drama. And if your bot isn't going to do more tasks, its bot flag should be removed. Emijrp (talk) 09:00, 30 July 2017 (UTC)
The issue is not in blocking, but in the (lack of) communication. The first communication was telling me that I am asocial, and I should know that because there were issues raised on Twitter and Facebook, plus an additional I helped you so many times improving your script which is just a blunt lie too. And I didn't say my bot isn't going to do any addional tasks, but it will not add any more descriptions. That is a different thing. Edoderoo (talk) 09:43, 30 July 2017 (UTC)

Perhaps queue for writes would be useful

Feed Apache Kafka (Q16235208) as fast as we can, then feed main servers as nice as we want.

Bot owners could then direct bots against Kafka servers - is this bad idea? d1g (talk) 17:38, 29 July 2017 (UTC)

A Kafka server is perfectly acceptable to provide data to the "recent changes" of projects. It will not solve the problem that we are growing the amount of changes and that this ability is at stake. Thanks, GerardM (talk) 06:56, 30 July 2017 (UTC)
When reads and writes are isolated, it is much easier to squeeze performance from other parts.
Less read servers = more write servers.
Kafka is much scalable than home-grown solution to solve exactly the same problem. d1g (talk) 07:58, 30 July 2017 (UTC)

Proposed building or structure

Bronnenpark (Q33219598) doesn't exist yet, still we want to indicate what it would be and when it would be that. Is the current solution acceptable for everyone? It's not showing up as a tram stop in the query service and it's not showing up as a violation in constraint reports. We can even generate database reports this way. Sjoerd de Bruin (talk) 20:11, 25 July 2017 (UTC)

I actually think that service for this would help significantly.
We cannot prefer only "current" events
Sometimes we want current items (countries, currencies)
Sometimes we want historic items (to fill items, to lookup biography in respective age)
Sometimes we want future items (to fill items)
Sometime we want everything (to count things)

scientific notation

The entry for atomic mass unit (amu) states that 1 amu = 0.00000000000000000000000000166053904±0.00000000000000000000000000000000002 kilogram. This reference site uses scientific notation to state its value as 1.660 539 040(20) x 10-27 kg. Both values are identical, but the latter is much more useful to users who understand what an atomic mass unit is. Is there any way that I can use the scientific notation in the field "conversion to SI unit" rather than the very cumbersome expression currently there.? Martinvl (talk) 22:26, 29 July 2017 (UTC)

Date of award

Shanghai Tower (Q18547) won the 2015 Emporis Awards, meaning it won the Emporis Awards for a building finished in 2015. But the award was given in November 2016. How do I show that in the statements ? --Zolo (talk) 07:41, 30 July 2017 (UTC)

construction (Q385378) with end date
Emporis Skyscraper Award (Q1339438) with point in time. d1g (talk) 08:53, 30 July 2017 (UTC)
Yes they are. The issue is that we will have a Emporis Skyscraper Award (Q1339438) with a point in time (P585) with a date in 2016, while this edition of the contest seems universally known as the "2015 Emporis Skyscraper Awards" as the 2015 Emporis Awards, see for example the list shown in en:Emporis Skyscraper Award. edition number (P393) might work that, but that does not really feel right. --Zolo (talk) 11:06, 30 July 2017 (UTC)
Q166389#P166 (Academy Awards) uses the year, about which the award is given, not the year, when the actual award is given. --Edgars2007 (talk) 11:25, 30 July 2017 (UTC)
Separate items for every event: Emporis Skyscraper Award 2015 (Q33997538)
1 d1g (talk) 11:40, 30 July 2017 (UTC)
1 breaks Wikidata's convention that we use non-date-specific item in award received (P166). Using Emporis Skyscraper Award 2015 (Q33997538) as a for work (P1686) qualifier make work, but I don't think the way things are done in Emporis Skyscraper Award 2015 (Q33997538) is a good idea, as it means the point in time (P585) will have different meanings on different items. We might need a new "awarded for period" property ? --Zolo (talk) 12:22, 30 July 2017 (UTC)
Point in time is not main property, but a qualifier to different properties.
Previous agreement not able to capture delayed events.
I suggest to move this section to P166. d1g (talk) 13:56, 30 July 2017 (UTC)

League seasons

Hello. I want your opinion about that:


⟨ Q33726407      ⟩ instance of (P31)   ⟨ season of a football league ⟩
⟨ season of a football league ⟩ instance of (P31)   ⟨ sports season (Q27020041)      ⟩

Do you think is a correct structure? There is a mess with sports seasons.

Xaris333 (talk) 23:50, 28 July 2017 (UTC)

so one rule of thumb is to think of "instance of" as meaning "Is a", and "A subclass of B" implies that everything that "is a" A then also "is a" B. For that reason I think your P31's in lines 2 and 4 should eb P279's instead: The 2016–17 Premier League "is a" "football competition season", and also "is a" "season of a sports league" - at least those claims make sense to me. Most such relations should be P279's rather than P31's. Having two or more layers of P31's below a class makes it a "metaclass", which is sometimes needed but generally harder to think about consistently. ArthurPSmith (talk) 03:59, 29 July 2017 (UTC)

@ArthurPSmith: Like that:

⟨ Q33726407      ⟩ subclass of (P279)   ⟨ season of a football league ⟩
⟨ season of a football league ⟩ subclass of (P279)   ⟨ sports season (Q27020041)      ⟩

You could do even in a simpler way: see above.
--- Jura 17:24, 29 July 2017 (UTC)

@Jura1: Yes. So do we all agree that this it the appropriate structure? To show what a specific season is and to connect it with the league item. If yes, we can apply this to sport seasons. Now in 2016–17 Premier League (Q23009701) we have with instance of (P31) soccer competition (Q15838706) sports season (Q27020041) and Premier League (Q9448). I am not saying that are wrong, but some sports season items had different values with instance of (P31) and is complicate. We can agree to at least correct structure. Of course someone can add something more like soccer competition (Q15838706), but that does not influence the structure we are suggesting.

Another way could be (is it wrong?):

To me P3450 is a useless duplicate of « instance of ». All the competitions are competitions types that are instanciated each time. The beforehand solution was perfectly functional. This just add unneeded constraints, hence maintenance and bureaucracy burden. The same for festivals and all kind of periodic events.

Integrate Wikidata with non-Wikimedia wiki

Hi, I'm sorry if this is not the correct place for this question. I was wondering if it was possible to integrate Wikidata (with Wikibase) on a non-Wikimedia wiki. If yes, is there a manual or guide for how to do so? Reception123 (talk) 18:10, 3 August 2017 (UTC)

@Reception123: no, it is not possible. Jared Preston (talk) 18:12, 3 August 2017 (UTC)
Ok. Thanks for the answer. Reception123 (talk) 18:25, 3 August 2017 (UTC)
It might be possible depending on the added value of a cooperation. Thanks, GerardM (talk) 11:08, 4 August 2017 (UTC)

Hi, I got a quick question!

Hi, I'm not used to wikidata, I only use it when I want to add a link to different wikis if the article has them. I noticed that virtual assistant (Q3467906) has many links to it, but not automated online assistant (Q4826465). There's a lot of confusion it seems. There's also Intelligent software assistant (Q14002853), which only links to the portuguese wikipedia.

I was wondering how I could easily fix things like that, instead of asking here. I usually get this message when I try to delete a sitelink:

@Tetizeraz: We are here not trying to maximize the number if sitelinks in each item. Instead, we are trying to get as exact matches between the subjects as possible. If that results in two items with only one sitelink in each, that is the way we prefer. You can remove one sitelink and install it in another item if you like. But I prefer to move them by some tools we have. I do not know if that is standard, but I see a green "turn right" -traffic sign next to each sitelink. That tool allows you to move sitelinks from one item to another in one single edit. If some sitelinks do not fit in any present item, you are supposed to create a new item for it. Otherwise it is large risk that the sitelink will be reinstalled by somebody here, thinking that the removal was a mistake or in some cases vandalism. -- Innocent bystander (talk) 16:41, 4 August 2017 (UTC)

Place of a championship

Hello. Question of property about where an event take place.

Example, La Liga (Q324867) is a national championship.

We are usually use

⟨ La Liga (Q324867)      ⟩ country (P17)   ⟨ Spain (Q29)      ⟩

but sometimes I have found

⟨ La Liga (Q324867)      ⟩ operating area (P2541)   ⟨ Spain (Q29)      ⟩

(the property is about organization not an event)

I believe that country (P17) is enough but I have see P2541 in some championships.

Or maybe the correct one is:

⟨ La Liga (Q324867)      ⟩ location (P276)   ⟨ Spain (Q29)      ⟩

And what should we use for a local championship like Divisiones Regionales de Fútbol in the Community of Madrid (Q2540334)? Maybe,

⟨ La Liga (Q324867)      ⟩ country (P17)   ⟨ Spain (Q29)      ⟩


Xaris333 (talk) 03:59, 3 August 2017 (UTC)

For national leagues let's continue using country (P17) to indicate the country (I think some Wikipedias tries to get the P17 value for their infoboxes if they are not filled in locally). location (P276) as a replacement for P17 does not look good to me, but it probably can be used additionally for local or regional competitions. XXN, 11:01, 3 August 2017 (UTC)
For leagues, I started using "operating area (P2541)". This especially in the UK, as using only P17 describes rarely the the geographic coverage. "location" seems to work better for the place of stadiums and other venues.
--- Jura 17:28, 3 August 2017 (UTC)
I believe that every competition or season must have P17 (except international). The issue is about to have or not another property for the place where the competition take place. In national competitions P17 value will be the same with the value of the other item. operating area (P2541) is not for an event. Xaris333 (talk) 18:59, 3 August 2017 (UTC)
Why do you think P2541 can't be used to describe "area this league operates in, serves or has responsibility for"?
--- Jura 04:19, 4 August 2017 (UTC)
@Jura1: a league is an event, not an organization. Xaris333 (talk) 04:31, 4 August 2017 (UTC)
I think that extending older country for sport (P1532) would make more sense than operating area (P2541)
Broadcasting company can have P2541, but not sport-related things IMO. d1g (talk) 21:50, 3 August 2017 (UTC)
Some "national" leagues includes also parts of other nations. The Swiss football-league includes teams from Liechtenstein (Q347). The national league of the Republic of Ireland includes teams from Northern Ireland. The Danish league in Aussie rules includes Swedish teams etc, etc. If I remember correctly, it has even happened that a Northern Irish team has won the Republics national league. -- Innocent bystander (talk) 05:03, 5 August 2017 (UTC)

Issue with HAL Airport wiki article

Hello, for the "HAL Bangalore Airport" article at English Wikipedia, Nederlands/Dutch is listed as a language on the left sidebar with the article title "Bengaluru International Airport". This is incorrect, as the latter article is about a different airport. However, when I tried to delete the Dutch article in HAL Airport's Wikidata item, it was not even there (see here). How can it be deleted? Sunnya343 (talk) 00:21, 5 August 2017 (UTC)

Importance of wikidata support in infoboxes

This is a rather broad/vague question, but I am asking because it is staring to bother me now. I've got an email about a week or so ago, stating that work is starting on supporting global templates (such as infoboxes and so on), so that complex templates need not be duplicated. That's great news, no issues there. Now, if you look masterpieces like en:Template:Infobox telescope, and articles that use them (click edit to see the magic), they all use various functions to fetch data from Wikidata. We all know that, no issues here either.

My concern is, if these global infoboxes are created, is converting heavily used infoboxes to something like Infobox Telescope, worth it? Won't the effort be wasted once the global templates are used? Rehman 14:39, 30 July 2017 (UTC)

My experience from svwiki is that templates designed like "Template:Infobox telescope" tends to be far too expensive for the servers to handle. The main infobox in sv:Stockholm (tätort) cannot be rendered in that way. I get a timeout halfway through the template. I am currently working on another solution, which tries to minimize the number of times you have to send questions to Wikidata. In sv:Användare:Innocent bystander/sandlåda you can see the progress! The work we do today, makes us learn more about how we in the best way can design templates and modules. -- Innocent bystander (talk) 18:00, 30 July 2017 (UTC)
work is starting on supporting global templates – I must have missed the email, interesting. Of course, it is worth. Larger communities tend to develop their own tools that fit their requirements, whereas smaller communities are the ones that will benefit from centralised tools. And I doubt that all infoboxes will be (and can be) converted to global infoboxes that all communities would approve.
For instance, cswiki uses a single module for fetching Wikidata and a ideally single template for rendering. Most infoboxes are as simple as this one, so not much work would be wasted in that case. Matěj Suchánek (talk) 18:31, 30 July 2017 (UTC)
Thanks for the replies, User:Innocent bystander and User:Matěj Suchánek. I'm referring to adding Wikidata support to larger templates like en:Template:Infobox power station. Following up on responses that I received on Facebook by Mike and Asaf, and looking at Amir's proposal at Meta, I understand that these templates are most likely to be hosted on Meta. Since it is highly unlikely that they'll be on Wikidata, part or all of the coding of these global templates may/will be taken from the English Wikipedia (if it is the most polished wikidata-supported template at that time, of course). This means it is worth adding Wikidata support to more infoboxes, which is the answer to my initial question!
With regards to wikidata-supported templates putting too much pressure on the servers, I am not knowledgeable enough to comment on that. Perhaps someone who knows about that subject can comment? Regardless, thank you everyone for your responses. That was really bothering me, and was pushing me away from putting effort on working on such templates. Cheers! Rehman 02:15, 31 July 2017 (UTC)
The problem with the solution provided in "Template:Infobox telescope" is that you have to use functions like "mw.wikibase.getEntityObject()" at least once for every parameter in the template. In reality you have to fetch information from several properties in several items for each parameter. Just to get the area of a city you have to use "mw.wikibase.getEntityObject()" once for the number, once for the unit, once for the date (even if there is one or not) and once for the reference. And no matter if the reference has an item of its own, you have to use arbitrary access several times for each part of the reference. Since the same reference often is used several times in one item, there are workable solutions for that too, but they are not implemented yet. -- Innocent bystander (talk) 06:38, 31 July 2017 (UTC)
One large problem with these Wikidata-based templates is that the Wikidata-community has completely different opinions than the local community about what should be added to a parameter in a template/property. If somebody is an artist and an truckdriver, we here add both under "occupation". But the opinion on svwiki is that you are not "notable" as truckdriver, therefor you should not add that to a template. And what a "position held" is, differs in opinion between Wikidata and Wikipedia. A 19th century Swedish politician had normally not that as an occupation. It was something he did at his spare time. In fact, the Swedish riksdag still has a long holiday in the summer, to allow the farmers in the riksdag to manage their fields and livestock. -- Innocent bystander (talk) 06:38, 31 July 2017 (UTC)
Right. With increasing integration between the projects, the differences in information models between projects will become a bigger and bigger problem. Sharing data is easy (it's a primarily technical problem), but sharing information requires agreeing on the models of that information. Absent compatible information models, every single language Wikipedia will need local logic (template code) to do something with "occupation = truckdriver" in order to be able to use data from Wikidata. I see a lot of people working on things like adding twelve million records of data. Is anyone working on the information models? --Xover (talk) 07:02, 31 July 2017 (UTC)

Related (had wanted to ask this a long time before, but...). Could somebody clarify one thing? If I have Wikidata module and I invoke it several times in one infobox, there is or there is not some cashing? I mean, Wikidata object will be called everytime as a new one, or in second, third etc. time it will read information, that it had from first invoking. Grr... Not very technically correct, but I hope that at least somebody got the idea. --Edgars2007 (talk) 07:22, 31 July 2017 (UTC)

If it could be implemented, it would be a good idea, but it does not look like that is the case today. (I have no other insight but from editing templates and modules.) As I said, I am working on a workaround at sv:Modul:Sandlådan/Innocent bystander/WD2 which invoke the main item 'once and store the entity in a variable inside the module. The main template used here is edited in LUA-code instead of wikicode. Instead of using 1,6 seconds of CPU time, I use 0,5 seconds. My hope is that I can reduce that time even further by keeping record of the references used. -- Innocent bystander (talk) 07:39, 31 July 2017 (UTC)
It's essential to have already loaded data cached. So yes, this kind of cache is working. Matěj Suchánek (talk) 14:03, 31 July 2017 (UTC)

Rehman, which email are you talking about? Should you convert templates? I'd say "no", especially if there are other things that you can do. Not so much because the effort will be wasted when global templates be usable. I don't know when will they be usable, and in what form.

It's more because this "conversion" work is done by people on smaller wikis, who could be doing something that these wikis need more. For example, translate articles into these languages. Theoretically, anybody who knows wiki syntax well can make infobox templates without knowing any other languages; precisely because of this templates could and should be global. But people who know the languages in which smaller wikis are written have special knowledge - the language itself! Whenever possible, the application of that special knowledge should be prioritized over template-making.

And I'd say a similar thing about people who only know English: Instead of "helping" smaller wikis with copying templates, how about helping them in an even more fundamental way and join the project to create global templates? You can do it by contributing to the discussion about the project, proposing a technical architecture and implementing it.

Yes, it's hard, but it will be a major change that will take an enormous burden away from people who spend so much time tinkering with templates. --Amir E. Aharoni (talk) 13:55, 31 July 2017 (UTC)

Hi Amir. Thanks for your reply. I was referring to your email in which the linked Meta page was mentioned. Until I relocated that email recently (after posting the above), it seems that I have misinterpreted it as an established project to be carried out soon. Regardless, I look forward to assisting in that initiative wherever I can. Kind regards, Rehman 22:59, 31 July 2017 (UTC)

Hi, As I start from now in this discussion, let me explain the cawiki experience. Without know anything about the idea of having a "global infoboxes", in cawiki we started .-two years ago- the proccess of integrate hundreds of infoboxes in 10-12 "core infoboxes" that manage any situation related with a big theme or topic. It means: person, territory (geographic or administrative), organizations (doesn't matter if it's a business, national organizations or polítical parties), etc. The reason we do that was related with using Wikidata. Put WD on infoboxes is not very difficult, however, when you have hundreds of similars but differents infoboxes, it becomes a huge duty, exemple: everyday WD create new properties usefull to be introduce in some infobox, the effort to update one o dozens of them, is very different. So, we choose to create a few but very powerfull infoboxes with full access to WD and provide to editors the most easy way to use: "Just write infobox xxxx at the beginning of the article and "all we know" will show automaticly and you don't have to bother anymore". But, together with this simplicity, it must incorporate and respond to the legacy of the manual parameters. On the way we developed other improvements, not directly related to WD, but essential when dealing with so important "upgrade". The most spectacular improvement has been changing map management from "static" based on images (location map xxxx) to "dynamic maps" created depending on WD coordinates. The result has been amazing. Nowadays, 310.000 articles, almost 60% of all cawiki entries have one of these infoboxes; 48% attended just with the 7 most populars. I invite you to see a summary of capabilities and results and our migration roadmap. I hope our experience could be usefull for all of you, specially for small (as we are) wikipedies. Thanks, --Amadalvarez (talk) 08:18, 5 August 2017 (UTC)

how to convert collection of strings to wikidata ids?

@Fuzheado: Tool should respect all strings and pick 1 or more groups for them

Hi all,

From time to time, I'm checking the self-referencing links (?itemA ?propertyX ?itemA). Most of the time, I just revert the wrong edit and if it's possible and convenient, I add a correct value instead, but in some rare cases I'm not sure what to do.

For example for child (P40) (and all or given name (P735), the mistake is obvious and the confusion can easily be fixed.

But what cases about country (P17) or capital (P36)? What should we dot here?

SELECT ?x ?xLabel WHERE {
  ?x wdt:P36 ?x.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }

Try it!

Is there other properties where self-referencing links are exceptionally « correct » ? (or even just specific weird cases like Tree That Owns Itself (Q1421130)).

How can a paleontology enthusiast contribute to Wikidata?

Hey everyone. I'm one of the more active members at Wikiproject Paleontology on Wikipedia, and I've been curious about this place for a long time. I was wondering how or if I could contribute to Wikidata as a paleontology enthusiast, and conversely what WikiData has to offer to the coverage of paleontology on other Wikimedia projects and to the paleontological community more broadly. Abyssal (talk) 18:13, 4 August 2017 (UTC)

Welcome at Wikidata! There are of course plenty of things to do, and it is pretty common to start as a topical specialist in a given field, and broaden the scope of contributions with time – if one is interested to do so. This way one gets a good idea of how things are going here. It is advisable to look for experienced collegues in the WikiProjects Category, and to decide whether you’d like to support some existing efforts, and/or try something else nobody else is doing yet.
You can expect to find items about entities that have Wikipedia articles, but typically a bit more of then than you find in the large Wikipedias (since Wikidata covers all entities of, say, paleontology that are present in the entire Wikimedia universe). Our goal are, in practice, more or less twofold:
  1. On the one hand each individual item provides structured data that the connected sitelinks (Wikipedia articles) and other related articles can re-use. This centralizes information, eventually also the references for each fact, and of course interwiki links. Particularly smaller language editions with less workforce benefit from that (bigger ones are still somewhat reluctant to do so). The structured nature and the centralization make it also much easier to spot and correct inconsistencies, mistakes, etc. of individual data.
  2. On the other hand, Wikidata aims to be a valuable project beyond plain Wikipedia support. For that goal, you’d rather look at the content from another than the single item perspective: give me information about all important paleontologists; or about all extinct animals, and so on. For that goal you wouldn’t aim to make a couple of showcase items, you merely want to improve all relevant items to a higher base level. It is particularly important to identify each item exactly, this is what we do by linking them to external databases via identifiers on a large scale.
Both goals are not contradicting at all (except for the fact that they compete for your and our attention).
As a Wikipedia author you will probably not be confident with a couple of Wikidata-specific processes here in this project. However, policies and guidelines as well as hierarchies are much simpler than in the large Wikipedias, which allows quick learning. It is probably not useful to elaborate too much here, but you are invited to ask in case of questions (on this page or specific authors/projects).
Hope there will be other replies as well. Mine became pretty general now, and a bit lengthy. —MisterSynergy (talk) 19:18, 4 August 2017 (UTC)
@Abyssal: There is temporal range start (P523) and temporal range end (P524) (e.g. Hystricomorpha (Q532250)) which can be used to indicate the start and end of deposition of a unit, but also the range of a fossil. Not everything is worked out yet, so any input you have is valuable. --Tobias1984 (talk) 19:19, 4 August 2017 (UTC)

What is the difference between floruit (P1317) and work period (start) (P2031)/work period (end) (P2032)?

I can not figure out the difference between work period (start) (P2031)/work period (end) (P2032) pair and floruit (P1317), especially if floruit (P1317) is using start time (P580)/end time (P582). In the past I was using floruit (P1317) for statements like "19-th century" or "circa 1850" and work period (start) (P2031)/work period (end) (P2032) when more precise dates were known. But now I see that items like Guillaume II Le Roy (Q19544724) is using floruit (P1317) the way I would use work period (start) (P2031)/work period (end) (P2032). So is there a difference between concept of "work period" and en:Floruit which indicates the time when someone "flourished" or has been active? --Jarekt (talk) 18:39, 2 August 2017 (UTC)

  • P1317 is to indicate that a person was alive in a given year (or date/decade).
    --- Jura 05:21, 3 August 2017 (UTC)
OK so we use work period (start) (P2031)/work period (end) (P2032) for dates when an person was working and we use en:Floruit when a person was alive or active working. The 2 terms seem to have very large overlap especially since all we know about many of the artist is their work. --Jarekt (talk) 12:01, 3 August 2017 (UTC)
hello all...
floruit (P1317) was created first for floruit, and at the time, the necessity for a period of time was not seen as important...
then, the possibility to give a fork period of time for floruit lead to the creation of work period (start) (P2031)/work period (end) (P2032), especially, because of Commons and wikisource specific needs (see discussion at the time)
now, we tend to use work period (start) (P2031)/work period (end) (P2032) when a period of work is known... and only floruit (P1317) when we know that 'at that time', the person was alive (or "floruit") without knowing the full period of work (for example, we know that an author published a book in 1918, but we have no info about begining/end of the work period....
some contributors also use floruit (P1317) in reference for life dates... (x date of death > 1918, since floruit (P1317) in 1918....)
in fact, floruit (P1317) and work period (start) (P2031)/work period (end) (P2032) are very much overlapping, because floruit (P1317) should always be somewhere between work period (start) (P2031) and work period (end) (P2032) ;) --Hsarrazin (talk) 17:10, 7 August 2017 (UTC)

EveryPolitician is a mySociety (Q10851773) project, currently funded by Wikimedia Foundation, that aims to integrate data with the EveryPolitician project and/or other reliable sources, as well as to come up with a suitable structure within Wikidata to encourage consistency of modelling of political data. My main task will be to involve people to become active on Wikidata, to learn how to use the various tools we already have (from gadgets to external tools such as QuickStatements, Mix 'n' Match, PetScan, and so on) and to actively reuse data from the project to build New Fantastic Tools™.

So, if you're interested in sorting out electoral/political data from your home country, or define data models to help other users compiling this kind of items, or you have an idea about how to visualise data, just {{Ping}} me, and I'll be glad to help. :) We're also planning events to add, fix, enrich and reuse data - the very first will be held in London after Wikimania, and I really hope to come back to you with more info ASAP.

Also, I'll be around at Wikimania all week, so feel free to tap me on the shoulder if you wish. :) --Sannita (MySociety) (talk) 14:42, 4 August 2017 (UTC)

@Sannita (MySociety): What level of government does this project intend to cover, and how far down into the hierarchy? Obviously nations would be covered, but what about states, provinces, cities, towns, etc.? Is it intended to only cover monarchs and elected officials, or some appointed officials too?  – The preceding unsigned comment was added by Jc3s5h (talk • contribs).
For the time being, we'll keep mostly at national level, covering Heads of State/Government, Ministers, and MPs, and tentatively first-level divisions. This will depend also on the data we can get from other sources (also from ones you can suggest us), so we'd also like to help document some sort of a general data model for the different cases, that can be further adapted later for every country, if needed. Hope I answered your question. :) --Sannita (MySociety) (talk) 16:37, 4 August 2017 (UTC)

@Sannita: Congratulations by your new role. I find by chance this discussion and I didn't know of the Wikidata:EveryPolitician project. It will be usefull to me, cause recently I created an infobox to show any level of administrative territory (state, region, municipality, etc.). Beside the population, coordinates, and so, it includes info related whit the government of the unit. One of the problems I had (and not solved yet) is how to known the political representation on the chamber (not only state, but municipality, for instance; and not only the governement membres, but the whole elected people) at the present moment. Obviously, a person could be member of political party (P102), but an organitzation doesn't have "member count (P2124) by each party in each legislature". If I understand, you create an item for each composition of cabinet (each government team, each legislature,...) with members and its qualifiers. So the chronological/historical information is not hold on the institution item, but in the successive governments items that are related with the institution. Two questions: Should the institution item have a property pointing to the present government ? Or, how to know fast and easy, what's the present government of an institution?. Second one: Could it be in the individual cabinet item a breakdonw by political parties with total of members ?, How to build it ?. Just one more: Where is the best place to ping you to have this kind of specific discussions ?. Thanks a lot, --Amadalvarez (talk) 09:21, 5 August 2017 (UTC)

@Sannita (MySociety): congrats for the job and godspeed for this wonderful task. Cdlt, VIGNERON (talk) 11:41, 5 August 2017 (UTC)
@Amadalvarez: Wow, that's a lot of questions. :D I'm not sure I can address all of that, nor that I should be the one to answer them all. Actually, what I found out is that we need to have a bit of a discussion about cabinets and how to represent them on Wikidata: for one, I don't think it is necessary at the time to show the cabinet, we can limit (as we are doing now) to head of Government/State, also because we still need to find a way to keep them updated, but for the future it may be a good point to raise. About the breakdown of parties that compose a cabinet, I think it is a good idea, but we need also to take into consideration how to represent those parties who don't have representation in the cabinet, but support it nonetheless - nothing impossible, it's just something that crossed my mind. :) As for the place to discuss, I'll be leaving for Wikimania tomorrow, but I plan to use some of my time there to try to propose and set up a Wikiproject for politics. I think it's time to coordinate the several national efforts into something bigger, while keeping the national approach to address the specific things that may arise (I do know how much different systems can be... "different"). Hope you'll join the party. :)
@Sannita (MySociety):I'm very sorry, but I won't be in Wikimania, but I'll go to WikidataCon in Berlin where I apply for a speech about "core infoboxes full WD powered". However, when I talked about a "place to discuss", I mean where are concentrate the discussions about the project for the present phases and for the futures topics as those I introduce. Anyway, I'm not in a hurry. Keep in contact about the evolution is enough to me. Thanks & have a good Wikimania ! --Amadalvarez (talk) 11:45, 7 August 2017 (UTC)
@VIGNERON: Merci bien. :) Sannita (MySociety) (talk) 07:49, 7 August 2017 (UTC)

'No value' casuing constraint violation

Should 'no value' be causing a constraint violation for "format", as seen here? I've not encountered that before, is it a new phenomenon? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:27, 6 August 2017 (UTC)

IMHO format constraints should not be applied to somevalue (aka unknown value) and novalue claims. The claim in question is fairly new, so I can't tell whether there was a change or not. If there was a change, it could be related to the new constraints infrastructure with claims on the properties. —MisterSynergy (talk) 14:56, 6 August 2017 (UTC)
Nikki actually brought his up a week ago on IRC (see phab:T172130), and with the next software deployment, format and other constraint types that look at the value will no longer report a constraint violation on no value Help or unknown value Help in the gadget (though KrBot’s database reports might behave differently). --Lucas Werkmeister (WMDE) (talk) 19:28, 6 August 2017 (UTC)
Thank you. @Ivan A. Krestinin: for comment. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:34, 6 August 2017 (UTC)
KrBot interprets novalue and somevalue as empty string. So this change makes such values acceptable. — Ivan A. Krestinin (talk) 05:17, 8 August 2017 (UTC)

Merge with quickstatements don't work?

There is some problem with merge in quickstatements? I found a lot of incomplete merge, you can see a little list in the box. Maybe is better lock until it isn't fix? @Magnus Manske:

--ValterVB (talk) 17:28, 6 August 2017 (UTC)

I observed the same recently, since a week or so User:MisterSynergy/sysop/empty items is full of incomplete mergers, much more than usual. I asked an editor who created many of those cases, and they claim to use the merge gadget for merging. Does anyone know what's on here? —MisterSynergy (talk) 17:38, 6 August 2017 (UTC)

--ValterVB (talk) 17:58, 6 August 2017 (UTC)

  • Based on phab:T127213 seems that it will not be fixed soon, sadly... The problem is in API as I understand. It doesn't perform a complete merge if there are merged two rich items, e.g. with overlapping descriptions, and passing as argument ignoreconflicts=description or whatever else will not help here. As a workaround currently there should be defined and called one more function to clear and redirect the source item, but this is not really a solution. Much better would be to have a simple API option to tell it perform complete item merges (including clearing and redirecting where is needed) on server side, instead of hacking around to do this from clients. XXN, 12:40, 7 August 2017 (UTC)
    • Maybe someone could try to provide a better explanation of the use case to developers ..
      --- Jura 10:59, 8 August 2017 (UTC)


Both are abbreviations at Q190001#P1813. I used the language tag "mul" as they can apply to several languages. Still, they can be differentiated by script. Should this be indicated in the language tag (e.g. mul-Latn or mul-Cyr, both not available yet) or with a qualifier (e.g. writing system)?
--- Jura 06:42, 7 August 2017 (UTC)

Technically you are right. The problem is how does a query show the result? Thanks, GerardM (talk) 08:13, 7 August 2017 (UTC)
  • It's a question about which of the two options to choose. Either can be "technically right" .. A query shows whatever is entered: the qualifier or the language tag.
    --- Jura 09:39, 7 August 2017 (UTC)
In the module we mainly use on svwiki, I have installed a function, that automagically prefer claims with qualifier "language:Swedish" or "script:Latin". See sv:Wikipedia:Sandlåda för Wikidata. I do not say that everybody have to follow, but I am quite pleased with how it works. It is mainly used for P558 (P558) and sometimes even for formatter URL (P1630). -- Innocent bystander (talk) 10:49, 7 August 2017 (UTC)
It should be easy to include "mul-latn" for the first approach mentioned above.

A property for Google Places types

Would a property to represent Google Places types be useful, to represent items that match the terms in this list? It would be used similar to the P1282 property (although much smaller scope). If this sounds worthwhile I will create a formal property proposal. Pauljmackay (talk) 14:33, 7 August 2017 (UTC)

See also GeoNames feature code (P2452) -- Innocent bystander (talk) 15:56, 7 August 2017 (UTC)
No, every item is already here.
Places types aren't helpful, use P31. d1g (talk) 17:13, 8 August 2017 (UTC)

Wikidata weekly summary #272


Hi, I created Wikimedia non-main namespace (Q35252665) to have a overview of namespaces in Wikimedia projects. Now I am not sure wether using has part (P527) is semantically correct and what would be an alternative for tagging this.

Second question: Is there a property to connect

--Bigbossfarin (talk) 17:36, 7 August 2017 (UTC)

If we were treating items linked to Wikimedia project pages as items about Wikimedia project pages for all purposes, the property would be main subject (P921), from the project page item. Whether we should treat them that way is unclear. There are several potentially serious issues with doing that, including the slight possibility that there may be one day an article about one of the pages/policies in question, and then we'd have a problem with one item linking as normally to the pages about the topic, and another linking to the topic itself. Perhaps we should treat such items differently, and not try to add statements to them at all beyond one statement identifying it as outside the main knowledge tree. --Yair rand (talk) 19:23, 7 August 2017 (UTC)

What happens to claims pointing to redirected (merged) items?

I noticed earlier today that Q15303967 (which was "national archives") had been merged to national archives (Q2122214) (which had a couple of sitelinks to different languages) - I'm sure the merge was fine, but it seems to have left about 150 other items slightly broken, as they had been instance of (P31) Q15303967 (so for example, any constraint requiring P31/P279* organization (Q43229) now fails). Do we have any bots automatically fixing these item redirects when the redirected item was used in statements on other items? I've fixed a few of them by hand, but I was hoping that wouldn't be necessary for all of them? ArthurPSmith (talk) 20:12, 7 August 2017 (UTC)

We have a bot fixing these. Quite annoying when the merge is wrong and you find that out months later. Sjoerd de Bruin (talk) 20:14, 7 August 2017 (UTC)
When it's a mistake, can't you use Rollbot run through the time period in which the bot was "fixing" the particular item? --Yair rand (talk) 20:42, 7 August 2017 (UTC)

Share your thoughts on the draft strategy direction

At the beginning of this year, we initiated a broad discussion to form a strategic direction that will unite and inspire people across the entire movement. This direction will be the foundation on which we will build clear plans and set priorities. More than 80 communities and groups have discussed and gave feedback on-wiki, in person, virtually, and through private surveys[strategy 1][strategy 2]. We researched readers and consulted more than 150 experts[strategy 3]. We looked at future trends that will affect our mission, and gathered feedback from partners and donors.

In July, a group of community volunteers and representatives from the strategy team took on a task of synthesizing this feedback into an early version of the strategic direction that the broader movement can review and discuss.

The first draft is ready. Please read, share, and discuss on the talk page. Based on your feedback, the drafting group will refine and finalize this direction through August.

Archiving of small talk pages

I think archiving talk pages like Wikidata talk:Autobiography (with 6 sections) is highly unwanted. Information that is still relevant gets more hidden this way. I also don't think it's practical to build a huge structure behind a page that is still nominated for deletion. Sjoerd de Bruin (talk) 11:48, 2 August 2017 (UTC)

6 section could be kept d1g (talk) 15:05, 2 August 2017 (UTC)
I agree and I think it's confusing on small pages. It would make more sense to me to only archive topics when the page is large enough (e.g. keep the last n topics no matter how old they are). - Nikki (talk) 22:21, 8 August 2017 (UTC)

People killed in duels

How should we indicate that people were killed in duels? Item duel (Q191503) is not currently a valid value for manner of death (P1196), though it is used this way (notably in Alexander Hamilton (Q178903)). It could be argued that a duel is different from a homicide, depending on where and when the duel was fought. - PKM (talk) 02:47, 8 August 2017 (UTC)

Our various death properties don't quite cover this - there isn't really a property for "context" or "circumstance", so we also have trouble expressing "was executed" or "was killed in X event" (eg a battle or an air crash). We could use a "significant event" qualifier but that doesn't quite seem right. A new property might be the way forward. Andrew Gray (talk) 12:16, 8 August 2017 (UTC)
I like that idea; it might also cover "presumed dead" situations I've struggled with such as "lost at sea". What other circumstances could we include here? - PKM (talk) 20:13, 8 August 2017 (UTC)

Super Cup

1) What is a super cup? For example, Supercopa de España (Q485997)


or something else.

For P279 is easy,

I am asking about the competition, not competition's specific years like 2016 Supercopa de España (Q20993924).

2) What is 2016 Supercopa de España (Q20993924)?

Are both correct? Xaris333 (talk) 02:23, 30 July 2017 (UTC)

2. both make sense, first is about one match, second is about series. Exact properties could be changed over time. d1g (talk) 08:49, 30 July 2017 (UTC)
For (1) I would just use P279 since this is not a specific cup, but a class of cups. For (2) I would prefer over if Supercopa de España (Q485997) is not a sports season (Q27020041). Danmichaelo (talk) 10:53, 31 July 2017 (UTC)

@Jura1:, @ArthurPSmith:, @D1gggg:, @XXN:, @Danmichaelo:, So,




We also have soccer competition (Q1478437). Υου can use this for the international tournaments (I don't understand the language of the links of the item), like FIFA World Cup, UEFA Champions League etc. And all the other above for national competition.

Xaris333 (talk) 00:59, 1 August 2017 (UTC)

@Xaris333, XXN: I'm just confused about soccer competition (Q34186974) and soccer competition (Q1478437). It looks to me like these can be merged (The German "Turnier" can be translated as "competition", we have a similar word "turnering" in Norwegian). Danmichaelo (talk) 17:28, 1 August 2017 (UTC)
@Danmichaelo: I can't speak German. But by google translating the article I get "They are deducted from football competitions which are decentralized and played over a longer period of time (eg national championships)." and "According to the origin of the participating teams, national, regional, continental and global tournaments can be distinguished. Distinctions are also possible afterwards, whether club, national or other teams or men or women teams participate in a tournament. Special tournaments are also available for teams whose players have not reached a certain age (U ... -selections) as well as for amateur teams."
So soccer competition (Q34186974) and soccer competition (Q1478437) are not the same. soccer competition (Q1478437) don't include national championships. soccer competition (Q34186974) include every association football competition. And all their example are about international cups. I am confused too. The dutch article is not helping. Is refers about cups (national and international). Xaris333 (talk) 18:09, 1 August 2017 (UTC)
I, as well, don't speak German or Dutch so I'm not sure if is OK to merge these items (on the basis of the 'de'- and 'nl'- wiki articles). But, in football exists some kind of distinct tournaments - unofficial & short, for which might be necessary to have an item (or not?). E.g. Jordan Tournament 1992, Nehru Cup 1993, Kirin Cup 1993, E.C.O. (Economic Cooperation Organisation) Cup 1993. XXN, 20:03, 1 August 2017 (UTC)
Well those are International football association cup competitions. There are 2 types: those which are for clubs (like UEFA Champions League (Q18756)) and those which are for national teams (like UEFA European Championship (Q260858)). Xaris333 (talk) 01:08, 2 August 2017 (UTC)
Right, seems like «Fußballwettbewerb» (focusing on German now) is used for slightly larger or more decentralized competitions than «Fußballturnier», but on the other hand de:Fußballturnier is a member of Category:Association football competitions (Q7015591) and Fußballwettbewerb is a redirect to de:Fußballturnier, so not sure if the items can be kept apart without confusion(?) The best would be to get feedback from someone familiar with German football, perhaps Steak? Danmichaelo (talk) 22:42, 2 August 2017 (UTC)
Because I was pinged: It is correct that often "competition" and "tournament" are used as synonyms. But strictly speaking they are not the same. The definition in de:Fußballturnier states that a "Turnier" is limited to a quite short time and centralized to one city or one country (e.g. a world cup). On the other side, competitions ("Wettbewerb") last longer and are played in many venues (e.g. world cup qualifiers). So these items should not be merged. Steak (talk) 07:56, 3 August 2017 (UTC)
Should be subclasses, not instances. Any premier league instance (say this year championship) is a championship. Hence the relationship is a « subclass of » one, per definition of subclass of. author  TomT0m / talk page 13:27, 3 August 2017 (UTC)

That's how I think is the structure of football competitions and football teams.

association football (Q2736) soccer competition (Q34186974) national association football competition (Q34548322) association football league (Q15991303) (like Premier League (Q9448))
national association football cup (Q34262376) (like FA Cup (Q11151))
league cup (Q1824674) (like EFL Cup (Q11152))
national association football supercup (Q34262807) (like FA Community Shield (Q189188))
international association football competition (Q34548368) international association football clubs competition (Q34548345) international association football clubs cup (Q34542757) (like UEFA Champions League (Q18756))
international association football clubs super cup (Q34542788) (like UEFA Super Cup (Q484028))
international association football national teams competition (Q34542827) (like UEFA European Championship (Q260858))
association football club (Q476028) association football team (Q15944511) (like FC Barcelona (Q7156))
women's association football team (Q28140340) (like FC Barcelona Femení (Q522899))
association football academy (like FC Barcelona Juvenil A (Q13562063))
national association football team (Q6979593) national association football men's team (like Spain national association football team (Q42267))
national association football women's team (like Spain women's national football team (Q847623))

It's not perfect. For example, for all items of soccer competition (Q34186974) you can't know if it a men or a women competition (can be solve by using women's association football (Q606060)). And an item may instance of (P31) association football club (Q476028), association football team (Q15944511) and association football academy the same time. In my opinion association football club (Q476028) shoulb be use only as a class of association football team (Q15944511), women's association football team (Q28140340) and academies and not with instance of (P31) at a team's item. And still there is no place for soccer competition (Q1478437). Xaris333 (talk) 02:12, 2 August 2017 (UTC)

These are all classes of competitions. I advocate for a long time now for ways to describe classes in term of their instances properties. I proposed, although it’s an unsatisfactory solution, to use « has quality » to describe the properties and the instances of a class : For example the «men or woman» competition class case could be solved by :
⟨ French national female football championship ⟩ subclass of (P279)   ⟨ football competition ⟩
⟨ French national female football championship ⟩ has quality (P1552)   ⟨ values in qualifier ⟩
participant class search ⟨ adult female ⟩
about participant class : I think I proposed this property but it was rejected, not sure why that would mean that all French national female football championship’s instances (say 2017–18 Division 1 Féminine (Q30174562)     , the last one) is a football competition with adult female participant.
this mechanism could be used in a vastly larger set of usecases … everywhere actually. author  TomT0m / talk page 13:43, 3 August 2017 (UTC)

@TomT0m: We can solve the problem with this way:

⟨ French national female football championship ⟩ instance of (P31)   ⟨ association football league (Q15991303)      ⟩
⟨ French national female football championship ⟩ sport (P641)   ⟨ women's association football (Q606060)      ⟩

Another "problem" is the use of the word national. For example, by "national association football league" I mean the league that take place in a country. This league is either a national one (clubs of all the country can take place), or local (clubs of one part of the country can take place).

i don't think we need separate items for this two (for example an item "local association football league"). But I believe the word national may confuse many users. I have changed the description to "league of association football that take place across a country or to a local area of a country". Xaris333 (talk) 19:13, 3 August 2017 (UTC)

@Xaris333: You don’t seem to be aware of the difference between instance of (P31)   and subclass of (P279). Please see Help:BMP - a document as old as Wikidata - and Help:Classification. Also en:Is a (a synonym of « subclass of »). All this makes
⟨ French national female football championship ⟩ instance of (P31)   ⟨ association football league (Q15991303)      ⟩
incorrect as « French national female football championship » is definitely not a single championship … it’s one championship per year. It’s a class of championship with one occurence (instance) every year. It’s very important that we agree on something as basic. author  TomT0m / talk page 19:38, 3 August 2017 (UTC)

So, @TomT0m:

Is that what do you mean? I don't disagree with this. We must change property P31 with P279 but this is not a problem. If all user agree of course. Xaris333 (talk) 19:45, 3 August 2017 (UTC)

@Xaris333: :Yep. We don’t have to agree on all the statements of that type, that would be exhausting. We have to agree on the principles that we implement. Then we just have to check wether or not statements (and not only on this case) meet those principle. This makes some choices natural and makes our model more predictible. Note that the principles in Help:Classification make sports season of league or competition (P3450)   just a special case of instance of (P31), the reason why I’m against :
⟨ 2017–18 Division 1 Féminine (Q30174562)      ⟩ instance of (P31)   ⟨ French national female football championship ⟩
. Note that actually we have so this statement may be more a statement that applies to the championship instances than on the class. On the other hand, there may be statements who apply to the class itself but not to the instances - so we must have a way to discriminate the statements that applies to the instances than statements that applies to the class. For example if a chemical element is a class of atoms, the abundancy in the universe is not a property of a single atom. That’s why I propose the has quality (P1552)   trick : the « has quality » statements applies to each of the instances, while the plain one applies to the class. author  TomT0m / talk page 20:12, 3 August 2017 (UTC)

@TomT0m: last few days we are changing the property to be like that:

⟨ 2017–18 Division 1 Féminine (Q30174562)      ⟩ sports season of league or competition (P3450)   ⟨ French national female football championship ⟩

Do you think we must also have

⟨ 2017–18 Division 1 Féminine (Q30174562)      ⟩ subclass of (P279)   ⟨ French national female football championship ⟩


Xaris333 (talk) 20:19, 3 August 2017 (UTC)

@Xaris333: Is there a proper definition of « sport season » ? If its a kind of recurring competition then we have « French national female football championship » that is a subclass of « sport season ». Then we just don’t need .
⟨ 2017–18 Division 1 Féminine (Q30174562)      ⟩ sports season of league or competition (P3450)   ⟨ French national female football championship ⟩
is useless. All of this is just a case of recurring events so the advantages of that scheme is that it’s not restricted to sport - or even to events recurring every year. (« sport season » subclass of « recurring event », specialized for sport competition recurring every year.
On the « sport season » definition, my understanding would be that a season is the set of all events in a sport between two summer breaks … which does not fit with that usage. author  TomT0m / talk page 10:36, 4 August 2017 (UTC)

I disagree. Xaris333 (talk) 10:54, 4 August 2017 (UTC)

@Xaris333: On what ? A little development would help justify our collective choice and rationalize our model. A little grounding on clear definition will help building a common language that make sense whichever your cultural background is. author  TomT0m / talk page 11:36, 4 August 2017 (UTC)

@TomT0m: Maybe we should use a new page about all these subjects: competitions, leagues, teams. Perhaps a subpage of Wikidata:WikiProject Sports. There are many issues to discuss as a community. With examples about everything. I have many questions and suggestions. Especially about association football. Maybe a subpage of Wikidata:WikiProject Association football will be better. Do you agree? Xaris333 (talk) 11:43, 4 August 2017 (UTC)

@Xaris333: Not really, as explained I think our problem here is not specific to sport and our thinking is valuable for recurring events. I would be OK for a project « recurring event » that would work in cooperation with the project sport. (edit conflict) even worse if we split each sport for stuffs that are common for all. Not opposed to such a project « association football » but restricted for stuffs that are really specific to it. That is not recurring competitions … author  TomT0m / talk page 12:01, 4 August 2017 (UTC)
On «sport season» Please read the different versions of wikipedias sports season (Q27020041)      … My observations is that the « season » notion has US specificities, is polysemic and that the articles are vastly unsourced. A poor ground for a model, or a recipe for problems. author  TomT0m / talk page 12:01, 4 August 2017 (UTC)

@TomT0m: You don't want a general discussion with all topic? Ok. Is your opinion. I will start one in Wikidata:WikiProject Association football for the users that are interesting. I can't talk for so many issues in different place anymore. Some agree with some properties/items, some disagree. We really need to agree and to organize the items. We need clear structure and guidelines. Now, everyone just add what he/she believes. There is a big mess. Xaris333 (talk) 12:07, 4 August 2017 (UTC)

@Xaris333: It’s easier to manage a huge mess if we solve the same problems consistently across wikiproject. I identified a subproblem that is relevant for all sports as well as a lot of other fields. We also have global sound principles = predictible behavior = less mess = less beliefs and more facts. Better take advantage of this. Hope that the association football team will participate in WikiProject Recurring events and help to build guidelines for recurring events and competition for everyone :p . author  TomT0m / talk page 12:48, 4 August 2017 (UTC)
If you aggree to a minimal properties about competitions/seasons/teams of football, we can generalize to other similar sports. Wikidata:WikiProject Association football/Discussion about properties Xaris333 (talk) 13:05, 4 August 2017 (UTC)
@Xaris333: To agree to a minimal set of properties, I’d have to acknowledge they are needed. I don’t think so, per my previous messages. It’s just a matter of type of competition occuring every year. I think the « season » notion is not really useful and is more a matter of day to day speach and do not add any information compared to « type of competition occuring every year ». With this reasoning, no reason to add a property if we don’t win anything, it’s added work for no good reason. So … what are we supposed to gain ? author  TomT0m / talk page 13:16, 4 August 2017 (UTC)

i%author  TomT0m / talk page 13:16, 4 August 2017 (UTC)

@TomT0m: you can write your opinion there, not under a Super Cup item discussion. Look, may be no one will participated. If so, I will stop trying to organize the items and the properties. If you don't have a guide, is useless. Everyone will do what ever he want. Say your opinion there if you want. You don't have to of course. Please Assume good faith for my actions. I just want to improve Wikidata, even a little bit. I don't think that all my opinions are corrects. That's why always I am asking the community, even for little things. And I have asked community so many times about what a specific league is. Which property (P31, P279) and what item to add. Is so confusing. I will stop the conversation here. Thanks for your time. Xaris333 (talk) 13:25, 4 August 2017 (UTC)
@Xaris333: Good faith is totally out of the equation. I’ll work on recurring events first, ping for your opinion, then we’ll talk about super cup. Imho a « supercup » is just a (recurring) competition that has criteria to compete into. We have to focus on criteria to select the competition participants. Here the competition notion helps … the « season » notion is cumbersome. Stay tuned. author  TomT0m / talk page 14:00, 4 August 2017 (UTC)
@Xaris333: To be more precise, a « one match » competitions. I propose

<Premier League (Q9448)> instance of (P31) < national association football league (Q15991303)>

  • "< Premier League (Q9448)> instance of (P31) < national association football league (Q15991303)>" mentioned above seems fine. I don't quite get when this should have become a class. I don't think there are multiple "Premier League (Q9448)". Please note that I added the English text of the items. This to avoid any confusion.
    Maybe there is a better concept whereof we can see Q9448 as an instance thereof. I'm interested in suggestions. If you are responding with templates, please state the language of the label you are focusing on, this to avoid any confusion.

We’re discussing this on the other page now. The key issue on this is the definition of a « league ». author  TomT0m / talk page 13:49, 8 August 2017 (UTC)
  • I don't think there is a definition where a league isn't an instance of a league. As this point isn't discussed at the other page. Let's finish it here.
    --- Jura 15:51, 8 August 2017 (UTC)

My opinion:

For every kind of competition (like Cup, Super Cup, National teams competition etc, see the table above) we are using the same structure. Xaris333 (talk) 16:10, 8 August 2017 (UTC)

What labels are you using for Q15991303? English?
--- Jura 16:23, 8 August 2017 (UTC)
national association football league, as you said. Xaris333 (talk) 16:30, 8 August 2017 (UTC)
It just one league .. the same since 1992. I think we should use P31.
--- Jura 04:47, 9 August 2017 (UTC)
So some users believe we should use P31 and some others P279. Isn't there any guide that would help us decide which is the appropriate one? Xaris333 (talk) 06:10, 9 August 2017 (UTC)
The property description of P31 can help: "that class of which this subject is a particular example and member. (Subject typically an individual member with Proper Name label.)"
--- Jura 06:15, 9 August 2017 (UTC)
I am ok with that explanation. Xaris333 (talk) 07:55, 9 August 2017 (UTC)
Well, « league » is also a subclass of competition. But 2016–17 Ligue 1 (Q22683328) is a competition. So this means that 2016–17 Ligue 1 (Q22683328) is an instance of league, according to current wikidata statement. What you need to understand the problem is a more complete help page on P31 and P279 : Help:Classification and to understand there is a mixup into 2 meanings of « league » : the league as an organisation and the league as a competition. That point is discussed there. author  TomT0m / talk page 10:01, 9 August 2017 (UTC)

No. Ligue 1 (Q13394) is a league. 2016–17 Ligue 1 (Q22683328) is one season of that league.

Xaris333 (talk) 13:01, 9 August 2017 (UTC)

Not that I disagree with that last list, but even if it's possible that Premier League (Q9448) could also have some P279 statement, I don't think this is relevant when discussing Premier League ([Q9448]]) as a league (Q15991303). Maybe it could also be an instance of something else? Any suggestions.
--- Jura 13:24, 9 August 2017 (UTC)

Thanks all for your time. Well, I have tried. Another failure. We will never agree about the structure about those items. Everyone will continue add what ever he/she wants. I will continue the same way. Nobody cares enough. Everyone it trying to impose his/her opinion. That are wikidata? A huge amount of mess that users don't care? I was ready to help, to spent many hours/days/months to correct all items. But without an acceptable guide, that would be useless. I am not an expert about many thinks in wikidata, sometimes English language that use is difficult for me, some definitions are not clear to me, but I really have tried. More expert user were not so willing to solve the problems.

All problems I have found are summarized on Wikidata:WikiProject Association football/Discussion about properties. Maybe in the future someone will use use them. Thanks again. Xaris333 (talk) 15:32, 9 August 2017 (UTC)

  • I was under the impression that it moved ahead quite far. Mainly thanks to you. The whole things seems to get much more consistent. I don't think it needs to be fully spelled out. There is always some oddity we hadn't thought of before. Besides .. in sparql ?item (wdt:P31 | wdt:P279 ) wd:Q15991303 could get you the same result as ?item wdt:P279 wd:Q15991303 .. "competition" in this context seems to be problematic as it could be a match, a season, a league, a league system .. etc. For those who like that, maybe we could just leave subclasses of that in parallel.
    --- Jura 15:46, 9 August 2017 (UTC)

Jura1, so many discussions about all those properties, you can't find just one that all agree. Everytime there are user/users with a total different opinion about structure, properties, items. Everytime some users stops talking, everytime discussions are stopped without a final solution. Even for teams that might be the easiest category, there are many different opinions. It's disappointing. 16:08, 9 August 2017 (UTC)

Fix geographical locations descriptions

Hi, My bot worked for many descriptions in "en,ru,de,el ,eo,es,et,fa, fr,it,nb,sco,nl" and some time the bot make mistakes in different languages.

I created a list for all the descriptions that my bot worked on it and I'm asking for help to check on them and correct them if needed. You can help in the following pages by confirm the correct description or by marking incorrect description and add the new correct description.

I find it impossible to provide any assistance because you fail to provide links to your edits and you fail to state the name of your bot. Jc3s5h (talk) 22:46, 2 August 2017 (UTC)
The bot is User:Mr.Ibrahembot. However, this is not important for this request, since you just need to pick the languages you are proficient in, go through the corresponding list provided above (if there is any), and add corrections wherever necessary.
User:Mr. Ibrahem/fix descriptions/de is already corrected. —MisterSynergy (talk) 22:59, 2 August 2017 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── When I look at the table for English, this is how it begins:

en, en-ca, en-gb
type old description new description country
human settlement (Q486972) human settlement in Netherlands human settlement in the Netherlands Netherlands (Q55)

The new description isn't being applied to human settlement (Q486972), nor is it being applied to Netherlands (Q55), so I don't understand what items(s) this new description is being applied to. Jc3s5h (talk) 10:05, 3 August 2017 (UTC)

The bot operator was a bit too eager and added descriptions with mistakes to plenty of items of different types, in plenty of languages (see above). They now ask proficient speakers for correct versions of the descriptions for a repair job. The “old description” values have been added to various sets of items (you can find them e.g. with the query service: en-desc: "lagoon in Dominican Republic"). However, for the request by User:Mr. Ibrahem this is not important to know. They only want to know which of the old descriptions are good, and which ones need a correction—both from a pure language point of view. You are not expected to correct the mistakes by yourself, this will be done by Mr. Ibrahem (or their bot). —MisterSynergy (talk) 10:38, 3 August 2017 (UTC)
thank you user:MisterSynergy for explain that, I will correct the descriptions and it's okay if someone do that but I need to know the correct description to make sure I fix my bot mistakes. --Mr. Ibrahem (talk) 10:55, 3 August 2017 (UTC)
I've just updated the nl descriptions. Empty new description = no correction needed, non-empty new description = correction needed. Mbch331 (talk) 15:01, 3 August 2017 (UTC)

  • I haven't seen the bot do this for my language. But we have no problems with definite articles here, since they are suffixes and not a word in itself. But we have problems with prepositions.

Cause of death categories

There is a discussion going on now with the category sorters on the en:Wikipedia. They determine what categories should exist, what categories should be deleted, what categories should be merged, what categories should be divided and put in some type of hierarchy. One problem with all this sorting, deleting, merging and creation of hierarchies is that they want to delete the biographical category Cause of death. I am a medical writer and I also like to speculate. This category could one day be a method of research to determine the relationship between a person, their ethnicity, their gender and a host of other characteristics that could be related to cause of death. This metric could have great potential if it were somehow incorporated into wikidata. I don't participate in adding content to wikidata as much as I would like, but I can certainly see the utility of allowing this sort of metric to this project. Any comments?

Best Regards, Barbara (WVS) (talk) 09:41, 7 August 2017 (UTC)
Information about the cause of death can be stored in Wikidata via cause of death (P509). ChristianKl (talk) 10:53, 7 August 2017 (UTC)
We are not tied to decisions taken in English Wikipedia. We can perfectly keep storing info about cause of death even if they decide to delete all related categories. Emijrp (talk) 11:26, 7 August 2017 (UTC)
Is there a way to facilitate that from my end. Would this appear in a biographical entry? Does it exist now?
Barbara (WVS) (talk) 11:50, 7 August 2017 (UTC)
The property is used in items like Ray Walston (Q692800). You are free to add data to other items. ChristianKl (talk) 13:28, 7 August 2017 (UTC)

SPARQL ORDER BY item - not by numeric nor by string value

"ORDER BY ?item" - what does that do?

SELECT ?item ?isni
  ?item wdt:P213 ?isni
ORDER BY ?item

Try it!


991,0000000121462392 15:42, 9 August 2017 (UTC)

That's not what it yields, it yields a list of URI's (?item is a URI) which are ordered in normal string ordering. If you want numeric ordering you need to bind another variable that is just the numeric part of the id, and sort on that. ArthurPSmith (talk) 15:52, 9 August 2017 (UTC)
ArthurPSmith, how is order Q192 , Q20, Q101942 normal string ordering? 16:01, 9 August 2017 (UTC)
Actually, the ordering does not work and the order is completely random since you are ordering bounds with "wd:" predicates which is undefined. Matěj Suchánek (talk) 16:17, 9 August 2017 (UTC)
Matěj Suchánek, so one can add statements to Wikidata SPARQL service that have no effect without getting a warning or an error? Users might trust that their ORDER BY statements work by string sort, since the CSV download gives strings. Apart from that, how can one numerically sort by QID? 16:31, 9 August 2017 (UTC)
How do you know it has no effect? If a sorting algorithm (Q181593) is unstable, the order is arbitrary but different. Anyway, use BIND( xsd:integer( STRAFTER( STR( ?item ), STR( wd:Q ) ) ) AS ?qid ). Matěj Suchánek (talk) 16:40, 9 August 2017 (UTC)
Matěj Suchánek, thanks a lot. I tested, and ORDER BY has an effect, and for the first items displayed it even had a reproducible order. Thanks for the BIND statement, works fine
SELECT ?qid ?isni
  BIND( xsd:integer( STRAFTER( STR( ?item ), STR( wd:Q ) ) ) AS ?qid )
  ?item wdt:P213 ?isni

Try it!

I also tried to remove the Wikidata-specific whitespaces from the ISNI, but that results in an error if not limited. Limited to 100 works fine for me:
SELECT ?qid ?isni
  BIND( xsd:integer( STRAFTER( STR( ?item ), STR( wd:Q ) ) ) AS ?qid )
  BIND( replace(?wd_isni, " ", "") AS ?isni )
  ?item wdt:P213 ?wd_isni

Try it! 18:20, 9 August 2017 (UTC)


wd:Q192 wd:Q20 wd:Q101942

aren't 3 strings, but 3 IRIs.

  • Without limit it would process 402507 statements, which would take too much time, so it would timeout.

  Question why do you need to process items in QID order? Is it something necessary to answer some question? d1g (talk) 19:51, 9 August 2017 (UTC)

d1g, privjet, the STRAFTER runs through without limit, and gave 409603 (not 402507). It is maybe not specifically necessary, I just prefer to have data ordered. I may like to compare two CSV downloads and simple diff tools might be better higlighting changes if the order does not change. Compare that with ListeriaBot which randomly rearranges lists, and it is hard to see with the MediaWiki diff function what actually has been changed. And to have data more compact, I want the ISNI in compact format. With ca. 9 millions ISNI issued that is 27 millions spaces that Wikidata adds :-(. 20:23, 9 August 2017 (UTC)
we have schema:dateModified
maybe we would have schema:dateCreated to sort for humans d1g (talk) 20:43, 9 August 2017 (UTC)

Delicate unmerge required Q30849 / Q14206373

Last December someone merged the project item page Q14206373 to blog (Q30849). It is going to need some delicate unpicking from someone who has a little time; or just revert back to the December 2016 versions of both pages, and let the rebuild go at its own pace. Thanks if someone has the time to resolve.  — billinghurst sDrewth 00:15, 10 August 2017 (UTC)

How to look up persons nationality?

Commons Creator page (Q24731821) use nationality and occupation fields to create phrases like Italian painter that describe people. Nationality on commons is encoded as 2-letter ISO 6116 code or as one of several "nationalities" that do not have a ISO code (like "English" or "Flemish", etc.). Nationality field roughly overlaps with country of citizenship (P27) property and my current approach was to look up ISO 3166-1 alpha-2 code (P297) of each country in country of citizenship (P27). That works for about 50% people, but unfortunately many country of citizenship (P27) properties link to items build for very specific period in history of a country and do not have ISO code. So how do I look up that Albrecht Dürer (Q5580) and Adolf Hitler (Q352) are "German" or "DE" ? --Jarekt (talk) 12:25, 2 August 2017 (UTC)

I doubt you can. The most direct path between Durer and Germany seems to be

But you cannot really use followed by (P156) in every case.

Beside, the handling of country of citizenship (P27) for older times in Wikidata does not seem to make much sense. I have never heard nor read that the country of citizenship of Durer was the Holy Roman Empire. --Zolo (talk) 13:49, 2 August 2017 (UTC)

I just look and many of the identifier databases lists nationality for Albrecht Dürer (Q5580) as "German", see RKD or ULAN. Maybe we need a new "nationality" property to capture such metadata? But what kind of items should such property point to? We could have set of items for the nations (instance of (P31) nation (Q6266)), like China (Q29520) or Korea (Q18097) which are not the same as the current country. Unfortunately the wikipedia articles do not differentiate between nations and countries. For example Russia (Q159)'s inception (P571) is 862, 1917 and 1991, and en:Russia article about "Russian Federation" talk about thousand year history. --Jarekt (talk) 15:35, 2 August 2017 (UTC)
So it is enough to fill correct city
All "country" information would accumulate at city pages
d1g (talk) 15:46, 2 August 2017 (UTC)
Actually there are two different issues:
  • which values should be used in country of citizenship (P27). There is no consensus even for seemingly simple cases like France in the 20th century, and it's much more complex for 15th century Germany. (I thought Nuremberg was a free city rather than part of Bavaria ? Either way, both "Nuremberg" and "Bavaria" sound better values than "Holy Roman Empire".)
  • It is commonly said (in respected sources) that Durer it German and Botticelli Italian. How do we indicate that. A new property ? Perhaps, but not sure about the label. Actually, we would even have any item to use as a value, as Germany (Q183) is supposed to be about an entity created in 1949. --Zolo (talk) 16:05, 2 August 2017 (UTC)
  • "Holy Roman Empire" is just wrong.
  • 19283 values in P27 correspond to wd:Q34266. Some countries (USA) don't need splits at all. France and Germany had a lot of wars, but we need to sort values eventually. d1g (talk) 16:44, 2 August 2017 (UTC)
(edit conflict) d1g, The problem is that country boundaries, political systems and government types are in constant flux. Some items for countries seem to be only for the current iteration, some for all iterations and some for both. Yesterday I had to revert a whole bunch of edits I made to P27 properties based on nationalities imported from Commons (I will not do that again). P27 does not seem the be a good property for determining nationality. So I am trying to better understand how such concept is being modeled and how it can be improved. The final goal would be for me to be able to look-up that Durer and Hitler were "German". --Jarekt (talk) 16:09, 2 August 2017 (UTC)
your questions are territorial, two mentioned persons have nothing common in "country" sense d1g (talk) 16:43, 2 August 2017 (UTC)
I agree that the countries are different but we are talking about concept of "nationality" and most sources describe both as having "German nationality" (see for example here and here). That is what I am trying to look up, and although there is a high correlation with P27 and P103 but those are different concepts. --Jarekt (talk) 16:57, 2 August 2017 (UTC) is not authoritative for values in P27:
"the object is a country that recognizes the subject as its citizen"
Proper source would be a list registry of citizens in some country.
So, government should recgnize it's citizens, not research institution. Especially art-centric institution.
Historical records cover 1000 years more or less after Genghis Khan (Q720), that's why everything is explained in Wikipedia. d1g (talk) 17:10, 2 August 2017 (UTC)
d1g, I agree with all your statements about P27. However, P27 is not the same as "nationality", Which I was asking about. So lets not talk about P27 but about where and how to store "nationality". I do not think we store it and I think we should. --Jarekt (talk) 17:42, 2 August 2017 (UTC)
Zolo, yes if we create new property than we might also have to create new items for some nations/nationalities to separate them from the items for the current countries. However we already have few such items, like China (Q29520) or Korea (Q18097). For some others a single item might do for both current country and nation, for example United States of America (Q30). --Jarekt (talk) 16:28, 2 August 2017 (UTC)
@Zolo: followed by (P156) is used incorrectly in that item, if anything it should be replaced by (P1366), but with several intervening items.
For pre-modern states, the equivalent relationship is typically "subject of", which is already an alias of the P27.
@Jarekt: The nation for that country would presumably be the American People.
Nations, as opposed to legal sovereign states, are extremely complicated. Making a usable system for identifying people around nations might not be doable. Some examples of relationships between states and nations:
  • The Egyptian constitution defines the Egyptian people as being part of both the "Arab nation" and the "Islamic nation", while many individuals may consider themselves to be part of the Egyptian people may not consider themselves to be part of the Arab and/or Islamic nations. Similar situations exist in numerous other countries.
  • The Irish and Jewish peoples are generally considered to be nations despite majorities of both groups residing outside their affiliated nation-state/country/territory and periods of time with those states/countries/territories not being under their sovereignty.
  • The peoples within the Plurinational State of Bolivia and the Home Nations of the United Kingdom are each considered to be nations of their own, while being part of the greater nation associated with the state/country. The First Nations (Q392316) in Canada and other aboriginal nations in other countries are considered to be nations despite not having associated sovereign states. This adds up to probably thousands of non-sovereign nations, some with or without autonomy or national government.
  • Virtually every item on w:List of ethnic groups is at least occasionally considered a nation, despite many not having ever had a sovereign state. According to w:Ethnic group, the term "ethnic group" is often used synonymously with "nation", and we already have a property for ethnic group (P172).
We currently have 2,292,412 country of citizenship (P27) statements. These statements are fairly clear-cut, since the topic is an unambiguous direct legal status. Dealing with fuzzier concepts of nations and such is much more difficult to find sources for, and is often controversial. --Yair rand (talk) 00:49, 3 August 2017 (UTC)
I think the term "nation" is misleading here, because it carries the connotations so aptly enumerated by Yair rand above. I think the use Jarekt is referring to above—the (compound) "Description" field of Commons Creator templates such as c:Creator:Pieter van der Borcht (I)—is distinct from, but partially derived from, the concept of a "nation" or the common uses of "nationality" (at least in the sense "Belonging to the nation X"). The pseudo-nationality of painters (and by extension also to printmakers, photographers, etc.) is one effectively assigned by art critics and historians, and is one that resembles and partially overlaps the concept of a "school" (style) of painting. For instance, a "Flemish" painter need not have any particular nationality or country of citizenship: any number of factors may have caused them to be considered "Flemish". It could be that the artist was active in the "Flemish" region (geographical region with numerous nations, changing hands several times in an artists' lifetime), or that they learned from a Flemish master, or (and) painted in the style of the Flemish school. Or, when this pseudo-nationality corresponds with actual de jure citizenships, a photographer may be considered a Spanish–Portugese artist, even though they lack citizenship in Portugal but do have both Spanish and British passports. It depends on which countries or schools the sources consider the artist to have strong affinities with. The same can apply for historical eras (e.g. "Mediaeval"), but that's usually treated as a separate property.
Thus, I think the concept Jarekt is looking for is one distinct from the concept of "Nationality", but with a sort of fuzzy derivation from it (multiple inheritance from citizenship, nation, school of art, work location, and style/genre). The good news, though, is that the number of variants that are not straight up 1:1 with a country of citizenship is limited (by art historians' ability to categorize). Judging by some random sampling, adding some way to say that a painter is considered "Flemish" or "Chinese" independently of their citizenships, or "German" or "Russian" despite their formal citizenships being in former (historical) states, would cover a huge part of the immediate problem. That is, a descriptive term not specifically tied to any de jure property (such as citizenship). And a lot of the needed data could, I think, be imported from Commons (and possibly also infoboxes on the Wikipedias), so long as we treat the concepts as distinct, since the immediate interested party (user) is Commons and artist biographies / artwork articles on the Wikipedias.
PS. As an example of why I think the concepts are distinct, consider an Austro-German painter of the Romantic school, with one formal citizenship in the Weimar Republic (among others), who also happens to be better known, and thus more notable as, a German dictator (nobody talks about him as an Austrian dictator). We need the concepts to be able to express all these facets depending on the context of the use: i.e Commons' perspective (the painting and writing) vs. Wikipedia's perspective (everything else).
PPS. I think I may have just ruined Godwin's law. :) --Xover (talk) 06:21, 3 August 2017 (UTC)
Yair rand, yes nationality can be confusing and complicated and controversial but for the great majority of people it is not. Commons creator templates (from which I am importing data at the moment) use Nationality field, which is also defined by template:nationality (used on Commons and Wikidata). In most of the cases the nationality can be encoded by language independent ISO 3166 codes with only a few dozen extra nationalities added for distinct nonexisting countries or regions. On commons we use hundreds of nationalities not thousands. Assigning "nationality" is also not that complicated as most of the identifier databases I checked specify the "Nationality" of a person (see for example RKD). Also, as Xover mentioned, it can be imported from other projects as most Wikipedia articles start with a phrase like "German poet", "Russian painter", etc. Also categories on Commons and Wikipedias are usually grouped by nationality. Nationality is also specified in En-Wiki en:template:Infobox artist and possibly other templates. I will be away from the internet for a few days and not be able to continue this discussion. --Jarekt (talk) 12:27, 3 August 2017 (UTC)
Hello Jarekt, long time no see ;)
on frwikisource's Authors, that uses the same nationality concept as Commons, we simply use a reference list of p27 which the lua template links to the corresponding gentile, like this, this way, we can decide to use "German" for "German Empire", "Germany", and all other names used through times.... or not (for specific places). I don't know if you could use the same system on Commons (that needs to be pluri-lingual), but in fact, we were inspired by the system that Commons is still using for converting languages... :)
when we find a new country (through Categories that list unmatched values), we just add it to the list...
what do you think ?
--Hsarrazin (talk) 16:50, 7 August 2017 (UTC)
Thanks for the suggestion Hsarrazin. I was thinking about generating my own version of a lookup-table like your s:fr:Module:Auteur2/nationalités, but than I figured out that if I need it on Commons and Wikipedia's Infobox might need it (because it is using such field) than others might need nationality of a person as well. Instead of all of us creating our own look-up tables it is better if we store them on wikidata. That is why I started this discussion. --Jarekt (talk) 03:04, 8 August 2017 (UTC)
@Jarekt: the subject is so vague and controversary that I sometimes don't understand. Can you define this property: "nationality"? How it should be separated from ethnic group (Q41710)? Is it nationality (Q231002)? --Infovarius (talk) 15:07, 8 August 2017 (UTC)
Infovarius, "nationality" is pretty clearly defined for people living in modern times and nationality (Q231002) is a good definition. It is closely related and sometimes synonymous with ethnic group (Q41710), citizenship (Q42138), and first language (Q36870). For people living in earlier centuries it is more tricky, I am not an expert on the subject, but it seems to be determined by first language (Q36870) and place of birth. Most biographies, in books and online, specify nationality, so do databases like ULAN or RKD, even if it is vaguely defined. We refer to Mikhail Bulgakov (Q835) as "Russian Writer" even though country of citizenship (P27) is Russian Empire (Q34266) and Soviet Union (Q15180). You might have Czech or Slovakian nationality but rarely Czechoslovakian. Some people are refer as "Yugoslavian" and some might be refereed to as "Serbian" or "Croatian". Some people might be Canadians (Q1196645) and some French Canadian American (Q5501705). If we create a property to capture "nationality" it will be important to use references in case of controversial nationalities. --Jarekt (talk) 15:54, 8 August 2017 (UTC)
You are not clearing anything. Mikhail Bulgakov (Q835) is "Russian writer" because he was writing in Russian language - this is simpler than "nationality". Another example, in Russia we have two adjectives: "российский" (demonym (Q217438) for Russia (Q159), includes Tatar, Chechen, Udmurt and other "nationalities") and "русский" (refers to Russian (Q7737) and Russians (Q49542), includes Russians in Ukraine (Q311762), Russian Americans (Q1140588) and other "nationalities"). P.S. If you are referring to a place of living then you probably can use demonym (P1549) of such place. --Infovarius (talk) 12:44, 10 August 2017 (UTC)

Wikidata Mapping

Hello, I'm currently connecting the geographic descriptors of the STW Thesaurus for Economics ( and I have a question for the term "Bodenseeraum" @de "Lake Constance region" @en. I would like to connect the STW descriptor "Bodenseeraum/Lake Constance region" with Lake Constance Lake Constance (Q4127) and add "Bodenseeraum/Lake Constance region" in "Also known as". I find that the Wikipedia page treats not only of the lake but the of the region too, for example: Tourism, leisure and sports, Towns and cities at the lake, climate, flora and fauna etc.

What do you think about ?

Thank's a lot Jdeillon: Jdeillon (talk) 10:55, 3 August 2017 (UTC)

I think it makes more sense to create a new item for "Bodenseeraum". Lake Constance (Q4127) is instance of (P31) lake (Q23397). ChristianKl (talk) 14:17, 3 August 2017 (UTC)
@ChristianKl: From a practical aspect, creating a new - and isolated - item would undermine one purpose of the mapping Jeanne mentioned, namely connecting STW descriptors via Wikidata to the relevant Wikipedia pages (in different languages). But I'm afraid it touches a more general problem, too: Often, the Wikipedia pages cover different things - in that case, the lake itself and the region, which belong to different and categorically disjunct classes. If we would try to separate these aspects in a clean fashion in WD, we would have to attach the Wikipedia pages to two separate items, which would be hardly desireable. The other option could be making Lake Constance (Q4127) instance of (P31) landscape (Q107425) (or some better fitting class), perhaps with lake (Q23397) as a preferred class. I've seen that approach in different places in WD, but I'm not sure if it is considered good practice. Or would facet of (P1269), mentioned in instance of (P31)/talk, be a better solution? Jneubert (talk) 11:05, 4 August 2017 (UTC)
Wikidata items aren't equivalent to the Wikipedia page. Wikipedia pages often cover more information. A new item might begin isolated but there's a good chance that it get's more statements over time. It might be very worthwhile to describe the meaning of Bodenseeraum with Wikidata statements. provides good data for describing it. ChristianKl (talk) 22:51, 4 August 2017 (UTC)
I see your point, but I'm not sure if I can agree completely (because somewhere the differentiation may be too fine-grained to be helpful). Anyway, extending the meaning of Lake Constance (Q4127) is not an option, because there is no consensus, and on the other hand creating a new item would not be very useful in the concrete context of the mapping. A solution could be to introduce a new "close match" property (in analogy to skos:closeMatch). Since similar situations - where the thing some external identifier designates is close, but not completely the same as a Wikidata item - occur in other places too, I'll try to come up with an according property proposal.

Consider "imported from" as a qualifier, not a source

(See Wikidata:Project_chat/Archive/2013/07#Not counting "imported from" as a source for a previous discussion)

Help:Sources#Different_types_of_sources says

statements that are only supported by "imported from Wikimedia project (P143)" are not considered sourced statements. If you encounter one of these statements, please remove "imported from" and add a more reliable source.

Why not just show those imported from Wikimedia project (P143) as qualifiers, like proportion (P1107)? It would makes it easier (i.e. without having to click on each "1 source") to check if a statement is sourced or not. The RedBurn (ϕ) 09:32, 10 August 2017 (UTC)

Import ISNI from VIAF

Can someone select items in that have a link to Wikidata and an ISNI, and check if the Wikidata item has the ISNI and add it to Wikidata if not present? 18:06, 4 August 2017 (UTC)

I think we don't do this anymore, because VIAF mismatched a lot of people. I would love a Wikidata game for this or some import to the primary sources tool. Sjoerd de Bruin (talk) 12:10, 5 August 2017 (UTC)
We recently exported from Wikidata a list of people with Open Library identifiers and their VIAF identifiers as we had it. We received a file with the Open Library redirects and duplicates. All the duplicates have been removed. I do not know the status of the redirects. As a result Open Library now includes links to both VIAF and Wikidata. Andy Mabbett did a trial run of an import from the Biological Heritage Library. They have links to VIAF and to Open Library. When we receive these values as well, we will enrich Wikidata and we will find issues. This is how and where we make a positive difference for us and for our partners. This is how we improve quality.
The primary sources data is a dead end. We cannot even query the data that is in there. It is a travesty that it is proposed for new data. It is not functional. Thanks, GerardM (talk) 12:44, 5 August 2017 (UTC)
There is active work going on to "revive" the primary sources tool. Sjoerd de Bruin (talk) 08:17, 7 August 2017 (UTC)
I recently learned that both VIAF and ISNI are managed by the OCLC. So when both are available, when they match a current record with either a VIAF or an ISNI identifier we enrich our content. So there are no downsides to this proposal. Thanks, GerardM (talk) 09:02, 7 August 2017 (UTC)
"Primary Sources" seems to be suitable for this type of data. Links between VIAF ids and ISNI aren't stable. If needed, one could always do some federated query based on VIAF id.
--- Jura 15:54, 8 August 2017 (UTC)

GerardM, User:Sjoerddebruin, User:Jura1: There are large gaps in the ISNI coverage. Just one example: Q268840 (Sally Potter) has VIAF, in VIAF has many connected IDs, including ISNI, and in Wikidata also has many other IDs. Why does the ISNI not show up in Wikidata? Yes, one can manually fix this, but the tools seem to be broken. The VIAF record history shows

SELIBR|276046	add	2009-03-03T12:03:42+00:00 // first entry
ISNI|0000000081584466	add	2013-09-16T16:15:07+00:00 // link to ISNI
WKP|Q268840	add	2015-04-14T18:56:54+00:00  // link to Wikidata

More than two years have past. What is wrong with the toolchain? User:Magnus_Manske, any idea? 14:00, 9 August 2017 (UTC)

Another example, Q611314,

LC|no2002074020	add	2009-03-03T12:03:40+00:00 // first entry
ISNI|0000000076892915	add	2013-09-16T16:15:07+00:00 // link to ISNI
WKP|Q611314	add	2015-04-14T18:56:54+00:00 // link to Wikidata

Why are the ISNI not automatically added? It could have been obtained automatically since 2015-04-14T18:56:54+00:00. How many more are missing? Thousands? A million? User:D1gggg and User:GerardM any idea? 23:47, 9 August 2017 (UTC)

Proposing the "primary sources tool" in this particular instance, when both VIAF and ISNI numbers are known, shows a misunderstanding of both VIAF and ISNI. First, ISNI does not accept imports that are below 95% accuracy. This is better than what we have at Wikidata as a general error rate. Second, we already have identified the people et al involved because WE associated them with Wikidata identifiers. As a consequence all arguments that there are issues with VIAF are issues with our own content as well. OCLC does administer both VIAF and ISNI so the compounded error rate is really small and it is a travesty to have people do manually work, introduce an error rate of 6% for no good reason. Thanks, GerardM (talk) 06:44, 10 August 2017 (UTC)
I don't understand your argument. ISNI has an error rate of 5%? At least now it's clear we shouldn't include it at all.
How did you reach the conclusion about a supposed error rate of Wikidata? Has this something to do with your edits with CatScan?
--- Jura 06:51, 10 August 2017 (UTC)
Obvious. ISNI does quality checks before they import new data. When they find an error rate of 5% or more, they do not include the new data. When data is entered manually, any tool or method, you introduce around 6% of new errors. Consequently when ISNI and VIAF share the same item identified at our end, the quality of that data is superior to anything we can do. Including the "primary sources tool" because its use introduces the same level of errors. Thanks, GerardM (talk) 09:38, 10 August 2017 (UTC)
I would be interested to see a reference for your claim that "anything involving a human in the loop has 6% error rate". − Pintoch (talk) 09:58, 10 August 2017 (UTC)
That is not relevant to the discussion. Suffice to say that any manual action introduces errors .. We are discussing the quality of importing combined data from an export by the OCLC where VIAF and ISNI are combined. With a proper script there are no new errors that will be introduced. When we run the export from the OCLC repeatedly the quality we get at our end will improve with time. Otherwise we remain unaware of their improvements. Thanks, GerardM (talk) 11:20, 10 August 2017 (UTC)
Why did you bring up this claim if it is irrelevant? Manual action can introduce errors, but it can also fix errors. That's why people curate databases! So it is totally possible to have a lower error rate with a manual import (by excluding the erroneous records, or marking them as deprecated in the case of duplicates). Again, if you had a source for your claims, I think many people here would be genuinely interested to see some quantitative analysis. − Pintoch (talk) 15:46, 10 August 2017 (UTC)
It is not a claim, it is a question. The point to the argument is that manual changes using any tool introduce errors. Running the same script without modifications will only introduce errors that are in the base material, something a manual process introduces as well. When you are questioning this basic assumption / observed fact, there is little point in arguing further. Thanks, GerardM (talk) 04:47, 11 August 2017 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── WD links to VIAF and VIAF makes a claim about ISNI. Adding ISNI with claim "stated in VIAF", "retrieved 2017-08-10" - how is that NOT better than the addition of an ISNI by an IP user or logged-in editor? And if one runs no script to check if the claim is still supported, how will one find errors that have already been found by others, namely ISNI-IA and VIAF? 18:30, 10 August 2017 (UTC)

ISNI format

(from IP talk)

Hi - your ISNI entries are not following the 4 groups of 4 digits separated by spaces that the ISNI property expects - for example here: in this edit. I think we have a bot that fixes these, but you should probably try to enter them correctly in the first place to limit the extra work needed. See the "format as a regular expression" statement for P213. ArthurPSmith (talk) 15:50, 9 August 2017 (UTC)

ArthurPSmith - ISNI is defined in ISO 27729:2012 as a 16-digit identifier. DeltaBot and KrBot changed my statements to the Wikidata-specific ISNIs. It is a pain that editors have to add the values manually, so add extra burden on editors by requiring Wikidata-specific formatting is just hillarious. 15:58, 9 August 2017 (UTC)
Note: I will stop adding any ISNI for now. Have a good day. 16:04, 9 August 2017 (UTC)

I also find "4 groups of 4 digits separated by spaces" format for ISNI quite annoying and it was a pain to add those spaces each time I copy it from a source that does not use spaces. Maybe we can display it with spaces but store it without? Or allow both formats? --Jarekt (talk) 16:16, 9 August 2017 (UTC)

You can enter it in any format. Eventually a bot normalizes it.
--- Jura 16:48, 9 August 2017 (UTC)

(from IP talk) It's not a Wikidata-specific thing, it's the standard display format. See the discussion on the talk page for the ISNI property - Property_talk:P213. If you go to and look at any entry, it is displayed there with spaces. You don't have to fix the formatting yourself - as I mentioned, there's a bot that does it - but if you have a long list of them there are plenty of bits of software you can use to add the spaces to the id's in your list (for example I've used OpenRefine and the expression "join(splitByLengths(value,4,4,4,4),\" \")" does the trick there). ArthurPSmith (talk) 19:22, 9 August 2017 (UTC)

ArthurPSmith: You say it is not Wikidata-specific, and then for reference the first source you point to is a Wikidata property page. The other reference is and "look at any entry" - but if I go to then the first ISNI I see, namely the one in the URL has no spaces. Yes, for display it has spaces. That is similar to

What to do with items that have multiple articles in same language wiki?

I'm sure this is answered somewhere but I can't find it. So I stumbled across the English-language article St. Cuthbert's beads (Q7587693) which in the USA we call Indian bead (Q3055342). Separate articles make sense as they have separate histories of being used as currency, etc. The scientific name for these are fossilized columns of crinoidea. In French they are known as entroque. The English Indian bead article and French entroque article share while the same Wikidata item. I've just created a category on Commons called Category:Crinoid beads that I have linked to Q3055342 (Indian beads/Entroque) since it contained two items. I've manually added a Wikicommons link to the St Cuthbert's beads article but Is there any kind of way to merge these on Wikidata so the Wikicommons category can be linked to both here? It seems like there should be a way for Wikidata to understand that Q3055342 and Q7587693 are the same thing. Or is the only option to engage in the mess of suggesting a merge of the two English-language articles to some neutral title (which even I don't support)? Wikimandia (talk) 21:37, 10 August 2017 (UTC)

First of all the items should be mutually related to each other by permanent duplicated item (P2959) (or, if there is doubt, said to be the same as (P460)). The interwiki links are not affected by this, they need to add them manually in the old style in Wikipedias or at Commons. —MisterSynergy (talk) 05:01, 11 August 2017 (UTC)

"date of birth" (P569)

The date of birth (P569) property has recently been edited to change the Italian label from "data di nascita" to "26 maggio 1938". I can't fix it because that property is semi-protected and I am not a confirmed/autoconfirmed editor on Wikidata. Could someone fix it for me? Thanks. —RP88 (talk) 20:44, 16 August 2017 (UTC)

Harvest Templates Issues

Trying to use Harvest Templates to pull dates of birth from members of the 14th National Assembly of Pakistan on English Wikipedia.

We have run into some issues which we can’t explain:

  1. The items we are interested in aren’t all in a usable Category within Wikipedia, but we are able to get them via a Wikidata SPARQL query.
  2. This list contains 342 people, which we believe we can input into the “Manual list” section of Harvest Templates.
  3. But when we hit “get pages” - we only get 25 pages returned.
  4. Of those - an even smaller set look like they actually get updated using the tool (we had to untick “don’t load items with the property set” - as we got an error with it set).
  5. Using Petscan with a SPARQL query, and template filter, we have verified that there are 120 of the previously selected items with a “Birth date and age” template, but no date of birth yet in Wikidata.

Any ideas of where we can find additional help with this? --Lucyfediachambers (talk) 08:54, 10 August 2017 (UTC)

"We" is that EveryPolitician employees?
--- Jura 07:32, 10 August 2017 (UTC)
Jura1. Apologies for not being clear on that we = me, Oravrattas (both EveryPolitician) and Saqib in Pakistan- who reached out about this and we've been attempting to puzzle this out together. --Lucyfediachambers (talk) 08:54, 10 August 2017 (UTC)
When you click "get pages", the tool will find all pages with template, up to the limit (10,000 by default). The "manual list" filter is only applied after all the pages (up to the limit) have been sent back. So if the pages you're looking for are beyond that limit (very likely given that you had to uncheck already set), you may never reach them. I would still try to find a category to filter. Matěj Suchánek (talk) 10:11, 10 August 2017 (UTC)
Ah, so the tool first finds all the pages with the specified template (with a limit), and then applies the filters? I had assumed that when you supply a list of pages, it starts with those, and then looks for the ones in that list which have the template. What is the ordering when a Category is supplied? Why does the same problem not occur — i.e where it first finds only the first 10,000 pages with the DOB template, again missing lots of other people when it filters those to ones in the specified category? --Oravrattas (talk) 04:51, 11 August 2017 (UTC)
All filters but the manual list are applied server-side, including category. (Note that you can also input a list of Qids but this will behave same.) Matěj Suchánek (talk) 09:55, 11 August 2017 (UTC)

Single category items?

Maybe I am mistaken, though I thought that current practice was not to create single category items, like Category:Champagnac-la-Rivière (Q32377107). What is our current practice?  — billinghurst sDrewth 13:54, 11 August 2017 (UTC)

I never heard of such current practice and WD:N does not claim it either. The Query Service just told me that we have ~2.7M items about categories with only one sitelink. —MisterSynergy (talk) 14:06, 11 August 2017 (UTC)
It's just that it shouldn't be a link to Commons.

PetScan (wikidata-labels)

Hello. Can anyone explain me how petscan - wikidata - Labels etc. works? Xaris333 (talk) 14:37, 11 August 2017 (UTC)

See PetScan on meta. Pamputt (talk) 16:12, 11 August 2017 (UTC)
Nothing about that section. Xaris333 (talk) 18:14, 11 August 2017 (UTC)
Hey Xaris333, your request is a bit vague. Can you please let us know a little more in detail what you want to do with petscan? —MisterSynergy (talk) 18:37, 11 August 2017 (UTC)
Nothing specific. I know how to use it, most of the options. But I haven't understood that point. "Labels etc.Note: The options below will be used as a generator, if and only if no other generator is used!... Has all of these labels..." How it works. Maybe that options helps me in future search, if I know what is it. Xaris333 (talk) 18:44, 11 August 2017 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── Okay, some comments about Petscan in bullet points. Maybe some of the aspects are know to you, but here they are:

  • Petscan is the successor of Catscan, which was a tool by Magnus Manske as well, designed to craw Wikipedias according to (primarily) categorization, but also for existence of templates, links, etc. Petscan also includes this functionality, but it also got a lot of connectivity to Wikidata which no other tool provides.
  • Many users are unhappy with the amount of functionality that this tool offers, but there is in fact a need for most of it. Even experienced users use “trial-and-error” method until the outcome fits their expectations.
  • Regarding the label function you asked for: as far as I understand, it only has an effect if no other input is provided in any of the tabs. But then you can quickly look up items which have certain combinations of labels, descriptions, or aliases. Try some inputs without filling any other field and learn from the results… I doubt that there is a useful description around for that functionality.

MisterSynergy (talk) 19:11, 11 August 2017 (UTC)

Ok. Thanks! Xaris333 (talk) 19:14, 11 August 2017 (UTC)

  • Search by label is based on raw sql database access, see source code. You can achieve the same result with Quarry, but in many cases SQARQL/PetScan is more than enough. --Lockal (talk) 21:18, 12 August 2017 (UTC)

Official website

Hi, I have noticed that the property "official website" is used a lot for people from the entertainment industry and firms and companies and so on, but not at all for people from the academia.

Basically, even if scientists have group webpages, we rarely add such infomation to our items. I found no evidence in my random sampling.

Is it on purpose? Is it a gap to fix? Any previous discussion about the topic?

In any case I agree that the name of the institution is enough to find the website, but it can be also use a source per se. Even if it is not a "third party source" the academic website is usually considered reliable on many platform as a source for basic academic information (Thesis supervisor, year of graduation, main awards...).--Alexmar983 (talk) 11:07, 12 August 2017 (UTC)

official website (P856) is also suitable for people from the academia, for them having official website (P856) with link to his/her profile on webpage of its institution is appropriate.--Jklamo (talk) 12:05, 12 August 2017 (UTC)

College Football Data Warehouse ID

What do we do when a website shuts down? "College Football Data Warehouse ID" for w:College Football Data Warehouse is no longer active since February 2017. --Richard Arthur Norton (1958- ) (talk) 03:12, 12 August 2017 (UTC)

Deprecate the formatter URL (P1630) of College Football Data Warehouse ID (P3560) (already done) and keep all identifiers. The links will not be generated any longer, but we can still somewhat identify the items that used this identifier. —MisterSynergy (talk) 05:35, 12 August 2017 (UTC)
Can we reformat the descriptor to point to the Wayback Machine so we can have a useable link again? We can go to "" from "" and take us from dead link to working link. --Richard Arthur Norton (1958- ) (talk) 15:16, 12 August 2017 (UTC)
I doubt that this would work, but I had the idea this morning as well. The archive URLs contain the archiving timestamp (as above: “20160805191715” for “5 Aug 2016, 19:17:15”) which is identifier-dependent and thus not stable. If an Internet Archive expert could point to a possibility to link the archived profiles without any varying parts, it might be an option to add a new (non-deprecated) formatter URL next to the old one. —MisterSynergy (talk) 16:05, 12 August 2017 (UTC)

Here are some random entries:

Note that an timestamp is down to second level, as noted above, so even if the whole site was crawled in one go, it might have subtly different timestamps for different sections. One approach you could use is to link to*/ - this doesn't go direct to the target page, but instead to a landing page with all the archive versions listed. It's not perfect, but it's probably good enough for a backup. Andrew Gray (talk) 11:06, 13 August 2017 (UTC)

Label changed to nil

At enwiki I am seeing a message from a module that the label for an entity has been changed to nil. It is the first of the following, and sure enough, it is not displaying a label. The second entity is just an example of something that works, where the label is shown.

elementary charge (Q2101) (update: this used to display "no label" instead of "elementary charge")
femtometre (Q208788)

However, the entity shows "elementary charge (Q2101)" even after I purged it. What's going on? Johnuniq (talk) 04:43, 13 August 2017 (UTC)

What's the exact error message you're getting? Mbch331 (talk) 07:06, 13 August 2017 (UTC)
I think this is still unresolved #P1027 does not show its label, is not found as "conferred by". Matěj Suchánek (talk) 07:45, 13 August 2017 (UTC)
How irritating. I tried {{Q|Q2101}} a few times, both here and at enwiki. Here, it was displaying "no label" instead of "elementary charge", while {{Q}} at enwiki displayed nothing for the label. I see that it has corrected itself. Conceivably erratic behavior like this could be related to T170039 concerning pages that display an error in mw.wikibase.entity.lua (see Tech/News/2017/31). Johnuniq (talk) 08:07, 13 August 2017 (UTC)
Well elementary charge (Q2101) didn't resolve itself. I did a hard purge on the item (purge with forcelinkupdate). Mbch331 (talk) 08:19, 13 August 2017 (UTC)
OK, but that is weird. I often need to use forcelinkupdate to purge error tracking categories at enwiki in order to find real errors, but I have never had a case where previewing a template would show an error, unless there was a real error. In this case, previewing my opening post showed "no label", and I'm sure I would have noticed if it did not show that problem after saving. In fact, you probably saw it showing "no label", then purged the item (which I had done, although without forcelinkupdate). I guess there is a caching layer between the underlying database and clients. Johnuniq (talk) 09:39, 13 August 2017 (UTC)
A likely explanation for the fact that a standard purge did nothing while a hard purge fixed the problem is that a standard purge merely flushes the HTML cache for the rendered page, while a hard purge presumably also flushes the database caching. Johnuniq (talk) 22:13, 13 August 2017 (UTC)

Countries, places etc for sports

I will ask again because is so confusing. In many sports competitions and seasons there is a problem with places. I am writing down all possible cases.

Previous discussions:

1) National club competitions and seasons: competitions and seasons that a team from all the country (one country) can take place. The competition held only in one country, nowhere else. For example, Serie A (Q15804). Any team from Italy, and only from Italy, can be on that championship and the competition held only in Italy. It's not a local championship and its not about more than 1 country. In that case we are using ONLY country (P17) --> Italy (Q38). No need for other properties like operating area (P2541).

  • Problem 1a: Special case: Teams of countries of the United Kingdom: At association football UK have 4 association. And we agree (?) that we will use country (P17) --> United Kingdom (Q145) with operating area (P2541) --> England (Q21) (for competitions or seasons that held only in England). The problem is that in P2541 description says that is only for organization, not for an event.

2) National club competitions and seasons at local level: competitions and seasons that a team from a specific part (or parts) of a country (one country) can take place. The competition held only in one country, that specific parts of the country, nowhere else. For example, Eccellenza Abruzzo 2010–11 (Q5332172). Only teams from Abruzzo (Q1284) are taking part. In that case we are using country (P17) --> Italy (Q38) with operating area (P2541) --> Abruzzo (Q1284). Is that ok?

country (P17) --> United Kingdom (Q145) with operating area (P2541) --> Dorset (Q23159) (England is not shows in that case.)


country (P17) --> United Kingdom (Q145) with operating area (P2541) --> England (Q21) and another property for Dorset (Q23159)?

  • Problem 2b (for seasons): Same with 1b.

3) International club competitions and seasons. Competitions and seasons that a team from more than one country can take part. The competition held in many countries. For example, UEFA Champions League (Q18756). (Some competitions like American Hockey League (Q464995) that take place in 2 countries are not a problem. We are using country (P17) for both countries and face them as a national championship - case 1 above).

  • Problem 3c: If we are going to list all countries with P17, what are you going to do for UK, if only England took part? And not Scotland, Northern Ireland and Wales for example. Should we use England at P17?
  • Problem 3d (for seasons): Same with 1b.

Comment (for seasons): For stadiums for club competitions, we can use home venue (P115) as a qualifier for each team with participating team (P1923). Example, 2016–17 Cypriot First Division (Q23756432).

4) International national teams competitions. Competitions and seasons that national teams are take part. Like UEFA Euro 2016 (Q189571).

  • Problem 4a (only for seasons): We are using country (P17) for the host country. Not for all countries that took part. I think is logical. But, why not to use operating area (P2541)? Or both? For example, France was the host country for Euro 2016. But the competition was about other 15 countries as well (ok, that maybe is a wrong thought, place is different from participating teams. That situation apply more to qualification phase, see problem 4d).
  • Problem 4b (only for seasons): We are using location (P276) for the stadiums. In these kind of competitions is easy because only some stadiums are been used.
  • Problem 4c: UEFA Euro 2020 (Q373501) is a national teams competitions that is not taking place in one country. Of course we can use P276 for stadiums. Are we going to use P17 for all countries that are going to host a game?
  • Problem 4f: Maybe for international competitions on national teams we can use P2541 to list all host country/countries using applies to part (P518) (or something else) and not the continent. For example:

Xaris333 (talk) 08:16, 13 August 2017 (UTC)

Maybe we should create a new property for 1a if P1532 and 2541 aren't applicable. d1g (talk) 11:40, 13 August 2017 (UTC)
Something special for UK? Xaris333 (talk) 13:41, 13 August 2017 (UTC)

Stub categories

Hi! Today I discovered Wikimedia category of stubs (Q24046192), created in 2016 by @Pasleim:, and I started substituting instance of (P31) Wikimedia category (Q4167836) with instance of (P31) Wikimedia category of stubs (Q24046192). However, @Jura1: told me that "we don't want to reproduce Wikipedia's category system with subclasses at Wikidata", so I stopped the substitution. In my opinion instance of (P31) Wikimedia category of stubs (Q24046192) is better than instance of (P31) Wikimedia category (Q4167836) + category combines topics (P971) Wikipedia:Stub (Q4663261). What's your opinion? --Epìdosis 14:00, 6 August 2017 (UTC)

I agree that there's no reason to duplicate Wikipedia's category system. Adding Wikimedia category of stubs (Q24046192) adds no data that isn't already accessible from the parent categories. --Yair rand (talk) 17:11, 6 August 2017 (UTC)
I agree as well that we do not want to replicate the category system (doesn’t work anyway, since category systems are somewhat different in each project). Category items are about a Wikimedia page outside the main knowledge tree (Q17379835), thus we should not put too much effort into them—they are basically here because Wikidata manages their sitelinks. However, if there is a use case that requires special subclasses of Wikimedia category (Q4167836), I wouldn’t object Epìdosis’ efforts. But I don’t know of such a use case yet… —MisterSynergy (talk) 18:42, 6 August 2017 (UTC)
Since almost the beginning of Wikidata till 2016 people were using subclass of (P279) Category:Stubs (Q2944440). P279 is clearly not the right property to establish the relation between two Wikimedia categories. I mass removed the relations but multiple users protested. As a compromise I added instance of (P31) Wikimedia category of stubs (Q24046192) which follows the idea of Wikimedia templates category (Q23894233), Wikimedia administration category (Q15647814) and Wikimedia disambiguation category (Q15407973) --Pasleim (talk) 09:52, 7 August 2017 (UTC)
That's an improvement indeed. Personally, I mostly rely on "category combines topics" (P971) and "topic's main category" so (if these are not impacted) I should be indifferent to one or the other being used.
--- Jura 10:53, 8 August 2017 (UTC)
No a category should not refer to another category because the same structure does not exist in all Wikipedias. So I do object and imho there should only be an indication that a category is a category. Thanks, GerardM (talk) 12:58, 7 August 2017 (UTC)

@Yair rand, MisterSynergy, Pasleim, Jura1, GerardM: So, what should we do? Stub categories should have:

  1. instance of (P31) Wikimedia category (Q4167836) + category combines topics (P971) Wikipedia:Stub (Q4663261);
  2. instance of (P31) Wikimedia category of stubs (Q24046192);
  3. instance of (P31) Wikimedia category (Q4167836) + instance of (P31) Wikimedia category of stubs (Q24046192) + category combines topics (P971) Wikipedia:Stub (Q4663261)? --Epìdosis 17:26, 11 August 2017 (UTC)

We should not have stub categories at all. We have categories and that is it. Apart from that, I use "is a list of" "whatever" and I use qualifiers like "award received" "award name". It works so well because it allows Reasonator to compose a query with the results. This is one example. Thanks, GerardM (talk) 20:29, 11 August 2017 (UTC)

  • Preferably (1). This also avoids that category's main topic starts getting used on these items. BTW, Q29848066 is just another similar experiment.
    --- Jura 07:09, 14 August 2017 (UTC)

Currently "Nearby" links to Special:Nearby, but it could just as well point to list pages nearby the item one is on.

Property for the starting point of a linear item

I admit being a bit lost, given the amount of similar properties (destination point (P1444), start point (P1427), terminus location (P609), terminus (P559)). Is there a specific property (start point or whatever?) equivalent to the terminus (P559) property? In order to give both start-end points of a linear feature, for example: a particular street "starts" (??) at its intersection with Street X and "ends" (terminus (P559)) at its intersection with Street Y)?--Asqueladd (talk) 15:08, 13 August 2017 (UTC)

Hello, I was thinking of centralizing the sources on various wikis so that they can be accessed by various bots and be rated on various parameters like reliability, quality, etc. First logical step in this direction I could think of is the role of wikidata in same. Is there any existing feature on wikidata through which we can list sources? It would be a good option if we could use source on wikipedia with just unique identifier and page no, and fetch all other details of source through wikidata. Would like to know views of others on this proposal. Capankajsmilyo (talk) 13:44, 14 August 2017 (UTC)

That sounds like a simplification! I often use Q25711315 as source for villages of Sweden. It is a good source, maybe the only reliable source in the subject, but not for the names of the villages. So, is it reliable? YNeos! -- Innocent bystander (talk) 14:38, 14 August 2017 (UTC)
Reliability is a subjective term and I am not denying that. But this subjectivity can be defined for certain cases, through which bots can get basis for assessing the sources. But that comes at a later stage. As I have already mentioned, first step would be to give definition to sources itself. They are just plain texts with some being bound in templates like Citation on ENWIKI, etc. If they are sourced from a central location like wikidata or wikisource, its utility can be defined by editors in time. For example, this could also help in getting the statistics of usage of a particular source or help in preparing a blacklist of those which are certain cases of NON-RS. Capankajsmilyo (talk) 15:16, 14 August 2017 (UTC)
@Capankajsmilyo: are you familiar with meta:WikiCite? I think that's along the lines of what you're talking about. ArthurPSmith (talk) 15:32, 14 August 2017 (UTC)
That is similar to what I am proposing here. On going through the related Wikiproject though, it seems limited to subjects of science. To illustrate on the idea above, we have plenty of sources on enwiki:Jainism, none of which I could find on Wikidata. If I could get a tool to replace them with wikidata information, that would be great opportunity to define those sources as being related to Jainism. They can be made available to editors who want to add citations to other articles related to Jainism and to those who want to add sources on wikidata items related to Jainism. Capankajsmilyo (talk) 17:07, 14 August 2017 (UTC)
What's been implemented so far is probably mostly just in science, but the intent with Wikicite is to (in the long run) have a wikidata item representing every cited reference in all wikipedia's. How to do this is still somewhat up in the air. I think we don't do this very well even within wikidata at the moment. ArthurPSmith (talk) 18:19, 14 August 2017 (UTC)
How about importing all the Google books in Wikidata? Capankajsmilyo (talk) 18:23, 14 August 2017 (UTC)

Next step for lexicographical data: demo system

Lexicographical data on Wikidata, Lydia Pintscher, Wikimania 2017

Hello all,

During Wikimania, Lydia presented the status of the lexicographical data on Wikidata. You can find the slides here.

We're also happy to announce that there is now a demo system ready, where you can try structured lexicographical data as it will appear on Wikidata. Please note the following:

  • The system is not persistent for now, the information are not stored and will disappear if you reload the pages
  • The structure of the pages is based on the data model, but the content and the properties will be decided by the community in the future. We created a few for the demo, feel free to create others.
  • The design of the page is also expected to change, this is not the final version

Feel free to try it, give us feedback or ask questions. See also the Phabricator board. Thanks for your support! Lea Lacroix (WMDE) (talk) 14:09, 14 August 2017 (UTC)

Wikidata weekly summary #273

P155 and P156 qualifier constraint

Hello. Does the community agree with that changes? [3], [4] (@Lockal:)

Are we allowed to use those properties as statements and not as qualifiers (I know there are the exceptions of rare cases)? Now we mostly used them not as qualifiers.

Previous discussions:

I don't have an opinion or a suggestion. I just want to use them correctly.

Xaris333 (talk) 11:55, 11 August 2017 (UTC)

I guess nobody interest for this subject either... Although there are discussions that decided to use them as a qualifier, a user remove the constraint only by his own opinion, thousands of users add them as statements and nobody cares about that. So thats wikidata. Since in most items the properties are as statements, we just continue with that... We have a big problem with wikidata in general. And since the wiki is growing, the mess and the problems are growing too. Αnarchy... Well, nothing is going to change, so I will just continue add them as I believe. No one take enough serious the decisions that are taking in wikidata, so everyone is doing what ever he wants... Xaris333 (talk) 18:10, 11 August 2017 (UTC)

sorry, I was going to say something (I wasn't even aware of the qualifier constraint, and I've used these properties before) but I wasn't sure what to add. I don't think there's reason to despair here, or even be discouraged - sometimes a single property can be useful in different contexts and I think this is a case of that. Probably we should focus on relatively narrow areas and do what makes sense to us, and then try to reach consensus where the areas overlap, more than trying to enforce something top-down? ArthurPSmith (talk) 18:17, 11 August 2017 (UTC)
There were discussions and decisions about using them as qualifiers. What's the point if anyone can change those decisions without asking the community? What's the point if we don't have the willing to correct things? I know that every decision can change, but through a discussion. Now, I am just seeing a property that the community decided to use it a as a qualifier, most of the users use it as a statement, a user just removed the constraint and life go on... And I think that this apply to many other properties... Do we have rules? And if we have, does anyone follows the rules? Xaris333 (talk) 18:30, 11 August 2017 (UTC)
well we may see quite a bit of this sort of thing going forward now that constraints actually have a UI effect (before the last month or so, any constraint violations were hidden on report pages). Most constraints make sense. But a constraint that has been widely violated probably doesn't. However, perhaps we should try to get people to discuss on the property talk page before removing a constraint like this at least... ArthurPSmith (talk) 18:49, 11 August 2017 (UTC)
Another discussion: Topic:Tv00hex7b7bwpd4t. TLDR: introducing this constraint generated 266060 violations without any algorithmic solution. --Lockal (talk) 19:30, 11 August 2017 (UTC)
  Comment 2 first changes make sense, because
1. sometimes next/previous links are not ambiguous and
2. they refer to whole items, rather than individual statements
So usage as qualifiers isn't necessary d1g (talk) 00:27, 12 August 2017 (UTC)
How can that be? Previous and following are relative concepts that depend on a point or item of relevance. If something precedes or follows something there always needs to be a context, it cannot happen in isolation. Philip > Anne > Andrew > Edward ... children of QE2; Philip > Andrew > Edward ... male children of QE2. Album releases of a band, etc. Years 1996 follows 1995 (previous year) and 1992 (previous leap year). Book published might follow the author's previous work; the author's previous non-fiction work; the publisher's previous work; the illustrator's previous work; and so on. There has to be context, so I am interested in your examples where you see that P155/P156 do not have a context.  — billinghurst sDrewth 05:33, 12 August 2017 (UTC)
Anything. Models of cars. d1g (talk) 05:52, 12 August 2017 (UTC)
A model of car has context, it doesn't exist in isolation, the models are of a brand. Australian Holden Commodore is the brand, and it has multiple models since the 1980s. Holden has also built other cars and models. Also a certain model could be built in one country then they change place of manufacture, so if your were looking to track the models built in a country or at a plant, if you put an overarching P155/156, aren't you confusing that if you wish to track other components.  — billinghurst sDrewth 06:00, 12 August 2017 (UTC)
We don't need to use any qualifiers in most cases: Ford Model A (Q1167651) Ford Model A (Q515001) d1g (talk) 06:10, 12 August 2017 (UTC)
Looks like something that can be qualified, and doesn't run contrary to guidance.  — billinghurst sDrewth 15:11, 12 August 2017 (UTC)
@billinghurst: South Pole Telescope (Q1513315) follows (P155) Antarctic Submillimeter Telescope and Remote Observatory (Q4771004) - I'm not sure how that would be qualified? Thanks. Mike Peel (talk) 00:11, 13 August 2017 (UTC)
On what basis does it follow?  — billinghurst sDrewth 06:50, 13 August 2017 (UTC)
In the telescopes I think its make sense to use replaces (P1365) and replaced by (P1366). The one item replaced or replaced by the other. Is not a series. Xaris333 (talk) 06:59, 13 August 2017 (UTC)
Aah, replaced by makes more sense. I didn't know we had those properties, thanks! Mike Peel (talk) 22:48, 13 August 2017 (UTC)
Anything. TV seasons. d1g (talk) 06:56, 13 August 2017 (UTC)
Anything. Ceremonies and events. d1g (talk) 06:58, 13 August 2017 (UTC)

So, we are going to use them also as statements? Not all user agree to use them as qualifiers only. Xaris333 (talk) 09:23, 12 August 2017 (UTC)

I disagree quite strongly with the decision to remove the constraints without discussion. I think the constraints should be re-added, and only removed if a discussion on the property talk page results in consensus to remove. --Yair rand (talk) 20:57, 14 August 2017 (UTC)
I have re-added them 3 days ago. I agree with you. Xaris333 (talk) 21:43, 14 August 2017 (UTC)
In the event the qualifier constraint remains, we should determine which properties P155 and P156 should qualify. part of (P361) and part of the series (P179) are the most obvious two that come to mind. (I don't want to bother Maarten by suggesting instance of (P31)). Mahir256 (talk) 05:56, 15 August 2017 (UTC)

anti-war activist is not an occupation

@GerardM: has added occupation (P106) peace activist (Q36193099) to a whole series of articles, claiming that Wikipedia says these individuals' occupation was "anti-war activist". Aside from the fact that "anti-war activist" is not an occupation, the text he claims is in the articles appears to only be a category, and appears nowhere within the text of the articles examined. Either the information must be removed as being incorrect, or it must be corrected in some way. Is there a way to correct the information? If so, does someone have a bot that could run through all instances using the correct property for this qualifier? Certainly occupation (P106) is wrong, but GerardM has refused to agree. --EncycloPetey (talk) 20:29, 13 August 2017 (UTC)

"'anti-war activist' is not an occupation" For some value of "occupation" (occupation (Q12737077) is defined, in English, as "any activity of a person (hobby, work, pastime...)")). I think it is very easy to occupy one's time with anti-war activism. Perhaps you meant "'anti-war activist' is not a paid job". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:41, 13 August 2017 (UTC)
Did you look at the various ways occupation (P106) is defined and explained in all languages, or just seize upon a single one in English? occupation (P106) is for paid employment. --EncycloPetey (talk) 20:59, 13 August 2017 (UTC)


Yes, but since this discussion is in English, that's what I quoted. Here you go:

  • ast =
    cualquier actividá d'una persona (pasatiempu, trabayu, deporte, etc.)
  • bg =
    всяка продължителна дейност на човек (хоби, свободно време, работа, професионален спорт и др.)
  • bn =
    একজন ব্যক্তির কোনো কার্যকলাপ (শখ, কাজ, আহ্লাদ, পেশাদারী খেলা...)
  • ca =
    qualsevol activitat d'una persona (afició, treball, passatemps, esport professional etc.)
  • da =
    persons aktivitet, f.eks. hobby, arbejde, sport, ...
  • de =
    jede dauerhafte Aktivität eines Menschen (Hobby, Freizeit, Beruf etc.)
  • es =
    cualquier actividad de una persona (hobby, trabajo, deporte profesional, etc.)
  • et =
    igasugune inimese tegevus, nt hobi, töö, meelelahutus jne.
  • eu =
    pertsona baten edozein jarduera (zaletasuna, lana, denbora-pasa, lanbidezko kirola...)
  • fr =
    toute occupation d'une personne: passe-temps, travail, sport professionnel...

and that's just the first screen in the Labelister gadget, other than English. I also note from the item's early history that an attempt to merge it with job (Q192581) was reverted. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:31, 14 August 2017 (UTC)

+1. "Occupation" =/= "paid work" by our definition. - PKM (talk) 20:46, 13 August 2017 (UTC)
  •   Comment In English the generally acknowledged modern interpretation of "occupation" is for paid employment, or at least solid part of a career. It is would be useful to be able to have better granularity. We have many British clergyman, and gentry and peers of various realms who did the highest quality amateur research outside of their financial income. Similarly, daughters and wives of politicians, peers, etc. who did much social work funded by family or inheritance. Do we wish to differentiate between how users supported themselves in the world, compared to their claim to renown.  — billinghurst sDrewth 00:15, 14 August 2017 (UTC)
I recently did edits to modern payed workers, all modern professions should be sub classes of employee (Q703534).
E.g. barber surgeon (Q781850) is not linked to Q703534 d1g (talk) 02:00, 14 August 2017 (UTC)
@billinghurst: That would be a vocation (Q829183) or avocation (Q1267055), depending on how we choose to define them. I do not know whether we have a property tied to either of these. --EncycloPetey (talk) 02:10, 14 August 2017 (UTC)
We have approved by (P790) for example d1g (talk) 02:13, 14 August 2017 (UTC)
Employee as a superclass for modern occupations? Really so everybody who has such an occupation is not self employed.. REALLY? Thanks, GerardM (talk) 03:59, 14 August 2017 (UTC)
  1. I don't think we should stress about "real one-man company" or "contractor" nuances.
  2. Self-employed don't get money from the air.
  3. It must be legal form (P1454), not primitive instance of (P31) subclass of (P279) d1g (talk) 04:18, 14 August 2017 (UTC)
This we "should not" is exactly why the whole class system is a quagmire. It cannot be explained it is absolutely helpful and unhelpful at the same time. GerardM (talk) 04:24, 14 August 2017 (UTC)
4 classes should be enough to cover all profit-related activities, shadow economy and illegal activities if have interest to have them together.
Q33394442, farmworker (Q33394254), manual worker (Q33394058), white-collar worker (Q368758)
Maybe we should include Q781850, but then we should agree to state "end date"=unknown to a profession or similar. d1g (talk) 05:09, 14 August 2017 (UTC)
@GerardM: pay attention to d1g (talk) 05:20, 14 August 2017 (UTC)
and that tells me what? You did not make your point. Thanks, GerardM (talk) 06:56, 14 August 2017 (UTC)
@GerardM: we should use affiliation (P1416) (and P1454) to identify if they they are organization of member of organization and other ways
You said "so everybody who has such an occupation is not self employed" but we shouldn't make such conclusions based on P31/P279.
P31 should answer very fundamental questions, not what you raise d1g (talk) 08:05, 14 August 2017 (UTC)

We could use movement (P135) (though anti-war is more a political movement than philosophical; should we correct this property definition to explicitly allow political movements?). For example, I added it to Heather Heyer (Q36338039) with value anti-racism (Q582965). Anyway, if one person has been an anti-war activist, I think we should add "activist"/"political activist" as occupation. Emijrp (talk) 08:47, 14 August 2017 (UTC)

There are plenty of occupations that are no occupation at all. Poet for instance.. There are plenty of sportspeople who are known for their sport but do not make any money out of it. Affiliation is another non starter imho because poets have no affiliation either. Occupation is used as an indicator for the activities someone is known for, what occupies their attention not really their profession. Thanks, GerardM (talk) 09:14, 14 August 2017 (UTC)
Fully agree with GerardM, and that was my point with reference to renown. How we mention and remember people is not necessarily their occupation, eg. Octavia Hill (Q437462) or John Monash (Q2731333) or Francis Ledwidge (Q1387970). How do we intend to capture that?  — billinghurst sDrewth 12:38, 14 August 2017 (UTC)
I say again, that what we may need is a property for avocation (Q1267055), which is a "calling" that is not usually a paid position, such as missionary, sportsperson, artist, activist, etc. It is true that Olympic athletes and state poets are not usually given a salary for their position, but the position is still supported financially by the state. In a sense, they are paid, just not salaried. --EncycloPetey (talk) 13:17, 14 August 2017 (UTC)
@GerardM, billinghurst: The problem with your approach is that as for now occupation (P106) is not defined as an activity someone is known for, but as any activity of the person, which is far to broad and can include waking up in the morning, brushing one's teeth, putting on shoes, using swear-words or paying income-taxes. The only restriction as for now is that there has to be a corresponding item for the activity (which can necessarily be created) and that the statement should provide the source of the information (which meanwhile nobody takes seriously). Such a broad definition renders the data virtually useless. The fact that Wikidata editors (mostly) act reasonable and don't add statements in the whole range allowed by the definition doesn't solve the problem, just covers it temporarily, so that it surfaces later after growing to an unmanageable amount. And meanwhile brings other problems like one editor restricting himself arbitrarily on "activities one is known for", other one on "activities one makes his living with", and yet another one on "long-term or regularly repeated activities", "activities of one's own accord" a.s.o., who will engage in endless and hopeless discussions, whether a particular activity should be included or not.--Shlomo (talk) 09:28, 15 August 2017 (UTC)

We also have the problem that "Anti-war activist" implies the person was against all war of any kind, which is not always the case. Some anti-war activists oppose a particular war or cause, but support other wars or causes. Aristophanes, for example very vocally opposed the Peloponessian War in his plays, while praising the wars that had been fought against Persia. He only opposed war with neighbor Sparta, not war against foreign invaders. So @GerardM: how would we indicate that? --EncycloPetey (talk) 13:17, 14 August 2017 (UTC)

I do not indicate that, current category structures do indicate that. Thanks, GerardM (talk) 13:38, 14 August 2017 (UTC)
@EncycloPetey: This has nothing to do with the discussed problem of occupation (P106), this is just lack o sufficiently particularised definition of peace activist (Q36193099). As for now I can't see any statement, label, description or even discussion that implies, that this item should be used for "anti-any-war activist" only and not for "anti-some-particular-war(s) activist". As soon as this is clarified (which should be done on item's talk page), we can look for a solution for Aristophanes or other ones (using qualifiers, splitting items, whatever). But we'll still be facing the question, whether "anti/pro-anything-activism" is considered occupation as understood in occupation (P106), or we should better use political ideology (P1142), political alignment (P1387) or anything else.--Shlomo (talk) 07:15, 15 August 2017 (UTC)

Merge request

I am not too familiar with Wikidata and not at all with its tools, so I hesitate to possibly do harm by messing with the tools. But could someone possibly merge Category:Hamilton, New York (Q20088954) and Hamilton (Q3460721)? They appear to be identical. Thank you so much! --Stilfehler (talk) 11:52, 14 August 2017 (UTC)

Removal of labels by bots

Within the last days I observed the deletion of all labels of an id by bots. For instance it was done for Q14201291 by PLbot. Q14201291 is now a redirect to the id Q11904043 which represents a disambiguation page to different geographical sites all named أبو صير (variant أبوصير but the same). Unfortunately most of the users cannot speak Arabic that's why we are using transcripted Latin lemmas. But they differ by language using language-dependent writings like Abusir, Abu Sir, Abū Ṣīr, Abousir, Абусир and so on. Normally these labels should have both the same meaning and spelling.

These disambiguation ids will help to find the same lemma in languages with non-Latin letters and different Latin writings. It makes no sense to have a separate id for all writing variants.

I do not know/understand why bots delete these labels solely because of slight differences in writing. --RolandUnger (talk) 11:59, 15 August 2017 (UTC)

The Wikidata way to find these locations would be rather than visit a disambiguation page elsewhere.
--- Jura 12:14, 15 August 2017 (UTC)
@RolandUnger: If you don't want to have separate items for all writing variants, what do you suggest to do with Abusir (Q29390469), Abusir (Q28965736) and Abusir (Q11904043)? Merge is not possible since each item can only have one sitelink per project. PS. I would appreciate to get notified if my work is discussed here --Pasleim (talk) 12:22, 15 August 2017 (UTC)
Of course it is a problem if you have a wiki with identical articles (independently of standard or disambiguation pages). This is not a problem of Wikidata but a problem of quality control and maintenance at these wikis. With my knowledge of these ids or geographical sites I could merge them all. If a merging is not yet possible because of comprehensive merging of the wiki articles then the property P460 ("said to be the same as") should be set for both ids to find all variants for maintenance. In the case of Abu Sir the problem arose from bots which could not think about different lemma writing for the same thing.
The Reasonator tool is a nice one but not known to the general public and it should help to merge identical Wikidata ids. But if a bot will delete all labels then Reasonator cannot find a duplicate.
Maybe as a proposal: If we have different writings of (geographical) objects then we should have a list of aliases which is valid for all languages to save time to enter them for all languages. --RolandUnger (talk) 15:18, 15 August 2017 (UTC)

Here, I'm an idiot (Yet Another Whinge)

First time I've needed to update something cached away in Wikidata, and I find I'm an idiot! Nothing about the process, the editing, was at all obvious. How strange that an experienced editor (since 2004 Global Contribs) would have such problems? I succeeded, but it took more than a couple attempts... Why such a mismatch with expectations?

I noticed that the repository info on page en:Blink_(web_engine) was wrong. I even first searched for the maillist conversation that pointed me to the correct information for that factoid. Then got flummoxed at no link in the Infobox text. I don't remember what tidbit finally made me clicked on the "shadow source" for info being Wikidata.

(Hmm, possibly reading the page source, then using incantations to get to en:Template:Infobox, then realizing I needed instead en:Template:Infobox_software, and then finding the description of 'repo' there, and then seeing the mention of "attempts to acquire the repository link from Wikidata." "Beware of the Leopard" time...)

But that is problem one, hinting/reminding people that text may be sourced from somewhere mysterious.

(Hey, the blaring hooting notices hidden at top of the template page that "This template uses the Wikidata property: official website (P856)"
{*{Uses Wikidata|P856}}{{Tracks Wikidata|P856}}
would have told anyone something's afoot with 'repository' (P1324), right? Or perhaps... since that notice has a direct link to here Property:P856, the same kind of shortcut should be placed inline in the template help everyplace it mentions data 'might' come from Wikidata? I mention this because there is no obvious link in that help to Wikidata. Dumb, no?)

I don't know how I finally got to the page here Blink because, again, there is no obvious way to get from "this page may reference wikidata" to the mirroring page here to check if that the wrong information is from here.

But that is problem two, no obvious link to the wikidata 'shadow' page here given a page at :foo: wiki.

So I scroll down to "source code repository" and wonder what to do. Click 'Edit'. Why is 'Save' already checked?!? How do I save the changed data? The popup help says "Enter a value". How? The save link is grayed out! I still don't know - I think I experimentally clicked "Add Qualifier" or "Add Reference" and it just happened.

BTW: what's a 'Qualifier'? What's a 'Reference'? I wandered around and found Wikidata:Glossary#Reference and then scrolled up to see qualifier. But my question was really, how and where do I enter my justification for the change? How do I point someone to the 'proof' the change was reasonable? I still don't know if I did the right/best thing!

But that is problem three, how does one edit this pineapple correctly without everything blowing up?

(What is the best thing to do? How does one say "I know this item value is true because of the information I found at <blah>, be it web, book, newspaper, etc." ?)

A key problem described here is, how do you help strangers to quickly fix that one fact they found wrong in another wiki. They don't *want* to be here. They shouldn't have to jump through fiery hoops. Y'all have reams and reams of help, but that is actually a hindrance for the greatest number of editors, those from somewhere else. (Sorry, the important editors for Wikidata are not the most frequent people here, but rather the infrequent or one-time visitors.) Asking people at Wikidata:Introduction#Where_to_get_started to take a tour on elephant back is really discouraging.

And isn't it strange that a wiki, a set of wikis, somehow makes it quite difficult to navigate to information? Is this perhaps a missed facet for implementation of Wikidata at the "system level"? Poor Ms. U. N. Owen has near no chance to bridge all the gaps in order to remedy the smallest data problem. This is an implementation problem hampering a good idea.

Please take the time I've spent describing my experiences as an indication of how far from 'good' that experience was. There are far too many hurdles to jump now that data 'might' come from Wikidata. Without lowering those hurdles you leave the implementation unfinished, incomplete, and far from practical for your average editor. Shenme (talk) 00:19, 16 August 2017 (UTC)

Hey, look, at en:Blink_(web_engine) in the left sidebar under 'Tools', "Wikidata item" ! How helpfully mysterious to the occasional editor. Shenme (talk)
@Shenme: First: Come here and complain that templates on Wikipedia are poorly designed is not going to give you any sympathies here.
Some helpful soul over there has pointed out a gooder template, how it has listed a more complete set of interrelationships to Wikidata, and how uses of the template even include shortcuts (the pencil icons) next to each imported value in the infobox. All of these go very far towards giving the confused editor things to click on and hope to be unconfused. Shenme (talk) 22:22, 16 August 2017 (UTC)

Secondly: Your experience, as you describe it above, summarize well what I feel about VisualEditor or Flow. It takes some times to learn, and it does not help if you think that the idea behind them were bad from the beginning. (Belive me, WYSIWYG (Q170542) is pure evil!!!) -- Innocent bystander (talk) 06:04, 16 August 2017 (UTC)
(ec) I don't have to time to deal with all your whinges, so I deal with just one. There is a project to allow the editing of data from the wikis more directly in WD with a user interface, it just isn't here yet. The thing about fixing a data point in WD is that it fixes the same data point in each wiki, and that becomes a whole lot quicker and easier to do once. Similarly with centrally stored data, it allows the creation of pages in multiple languages that can at least show data in a contextual language where a wiki is yet to create a specific article. Rome wasn't built in a day.  — billinghurst sDrewth 06:10, 16 August 2017 (UTC)
I very much understood the great promise of centralizing data that should be uniform across the multiple wikis. That is why I went to the trouble of correcting something, here, rather than just jamming it in locally at enwiki.
When Rome conquered, they didn't allow uncertainty about how things would be done from then on. They made sure the rules were painfully obvious. No one ever complained "but we didn't know how to pay our taxes!" It remains the case here that how to submit taxes (or data) is unclear to the average plebeian. Having to travel to Rome, learn passable Latin and obtain favorable omens just to correct your middle name on the last census... Shenme (talk) 22:22, 16 August 2017 (UTC)

@Shenme: thanks for taking the time to point out your challenges in fixing something here. As billinghurst mentioned there is development work ongoing to make it easier to edit wikidata entries directly from wikipedia. However, I think the main point of your complaint was uncertainty in how to source the change you wanted to make which will surely still be a problem for more direct wikidata editing from the language wikipedias. I know Lea Lacroix (WMDE) has been working to get documentation here improved - Lea, should we perhaps focus on a one-pager simple outline for people familiar with regular wikipedia editing, on how to fix one claim with appropriate referencing? ArthurPSmith (talk) 14:17, 16 August 2017 (UTC)
As mentioned above, there are certainly improvements possible at the originating wikis. (I love the pencil icon shortcuts in the mentioned template.) Is it possible a "first visit" here can kick off a popup or page-top link to the quick cookbook recipe "how to make an omelette"? If they've just been dropped here from a wiki page pencil link, and it all looks so different and strange, a friendly smile and quick recipe will be very enticing. Shenme (talk) 22:22, 16 August 2017 (UTC)
Thanks Shenme for your description of the problems. I'm sorry that you encountered such troubles while editing.
About documentation: the first part of the issue is about the infobox on English Wikipedia. I think that the documentation should be improved there. Unfortunately, since each Wikipedia develop their own version(s) of infoboxes, we can't really provide a global documentation. We've been also working on Wikidata:How to use data on Wikimedia projects but it doesn't really help the casual editor, it's more for people who want to create new templates on their wiki. Maybe a simple page about how to edit Wikidata for Wikipedians could help - but again, with the problem of the different infoboxes from a Wikipedia to another.
I tried to reproduce the problem you encountered while trying to modify a link and add a reference, but I couldn't. If you edit Wikidata again and find this issue another time, I'd be glad to know about it so we can track a possible bug. Lea Lacroix (WMDE) (talk) 13:01, 17 August 2017 (UTC)

perceptible object (Q337060)

Any possible difference between perceptible object (Q337060) and physical object (Q223557) ? d1g (talk) 17:33, 16 August 2017 (UTC)

Yes, one is a philosophical concept (something perceived), and the other is a physical concept (something that has measurable properties). There's lots of overlap, but we seem to have 5 distinct language wikipedias with entries for both, so they are definitely deserving of being distinguished. The German terms "Gegenstand" vs "Körper (Physik)" seem quite distinct. ArthurPSmith (talk) 17:54, 16 August 2017 (UTC)
perceptible object (Q337060) is very similar to object (Q488383) IMO d1g (talk) 18:49, 16 August 2017 (UTC)

Categories for Cities?

A general question, but a specific example.

Cebu City Q1467 only had the category Q104157 "City in the Philippines". I added Q515 "City" for a top-level description of what it is. Is this the intended approach? Should I have added Q1549591 (big city) instead? Power~enwiki (talk) 19:37, 16 August 2017 (UTC)

For instance of (P31) (it's better to avoid the term category, this can get confused with Wikipedia categories), you should generally use the most specific item available - so city of the Philippines (Q104157) rather than city (Q515). The Philippines one is already a subclass of "city", so there is no need to add both - a properly constructed search will find both items marked with city (Q515) and items marked with any subclass of it.
big city (Q1549591) covers a different aspect of the item to city of the Philippines (Q104157), so it would be reasonable to include both (assuming it is indeed a sufficiently large city).
The one major exception to this is people, who should always simply be instance of (P31):human (Q5), not "woman", "doctor", "Danish person", or any other more specific group. Andrew Gray (talk) 20:29, 16 August 2017 (UTC)
The reason why we don't use "instance of woman" or "instance of doctor" is that we have more precise properties to express these relations: sex or gender (P21), occupation (P106). The same I think about "big city". We have population (P1082) to express how big a city is, so adding big city (Q1549591) in addition to city of the Philippines (Q104157) or city (Q515) seems superfluous to me. --Pasleim (talk) 09:01, 17 August 2017 (UTC)
+1 --Marsupium (talk) 12:07, 17 August 2017 (UTC)
That seems fair! I had assumed that big city (Q1549591) was recommended as it's fairly widely used, but I agree that it seems unnecessary (and a bit arbitrary) given that we can also represent population. I wonder if it's worth removing it in any case where population is listed. Andrew Gray (talk) 20:56, 17 August 2017 (UTC)

Means to flag constraint suggestions and/or variations?

Do we have a template to apply, or a category to add, where we have suggested on a property talk page for a variation or suggestion for a constraint? Leaving a suggestion sitting on a talk page without a little flag often means it can not be noticed by those with the skills to do so.  — billinghurst sDrewth 05:10, 18 August 2017 (UTC)

Wikidata and redirects in Wikipedia

We have Joest Henne (Q24035983) that is the same person as Joest Henne (Q30229797). In sv.Wikiepedia there is an redirect Jost Henne -> Joest Henne.

means to record location of a plate/illustration within a work, though not through a page number?

I see in Leuchtenbergia principis. Noble Leuchtenbergia (Q14554954) that the image has been identified as page(s) (P304) then "plate nnnn" which is a constraint violation. I am seeking the community's opinion on how an illustration's location should be identified within a work. We can sometimes put a page number, however, sometimes it will be "opposite p. nnn" or some other identifier that is not a page number though is evident within a work. Do we have an existing means outside of P304 to do this? Thanks.  — billinghurst sDrewth 05:17, 18 August 2017 (UTC)

You could probably use section, verse, paragraph, or clause (P958) with value "plate xx", but I think a new property might be the most elegant solution. - PKM (talk) 20:02, 18 August 2017 (UTC)

Interesting. In my case the image needs 80% or less to appear. --Janezdrilc (talk) 22:37, 19 August 2017 (UTC)
I think the image does always appear, but not always in the upper right corner. If you have a more narrow window the image appears in the left column, after all statements and identifiers, but before the links to different projects. I can make the image "disappear" from the right column even if the zoom is 50% or lower if the window is made small enough. This "dynamic layout" of the Wikidata interface (web pages) was very confusing to me on my first visits here. --Larske (talk) 23:49, 19 August 2017 (UTC)

P393 or P1545

Which one? (or something else?)

(Please don't discuss about P3450). I want to use P393 or P1545 as a qualifier.


P1545 seems more logical to be used. But, honestly, I haven't understood the difference between those two properties.

SELECT ?item
    { ?item wdt:P3450 [] }
    { ?item wdt:P393 [] }

How to express different alternatives for value-type constraints ?

What is the correct way to indicate that different acceptable alternatives exist, when specifying a property constraint (P2302) : value type constraint (Q21510865) ?

For example, position held (P39) can take a value that is either

(Sometimes made more precise through attching the qualifier of (P642) to the generic value).

How should one indicate this in the P2302 specification for position held (P39) ?

I tried simply adding subclass of (P279) below instance of (P31) in the statement (diff), to indicate that either is possible, but this is now producing a red error message on Property talk:P39.

complex constrains
if you need assistance, leave requests at talk pages or "request a query". d1g (talk) 15:58, 21 August 2017 (UTC)
(ec) A complex constraint would be one way to go, but I'd prefer to use the standard mechanism if possible.
I see that Metamorforme42 has tried changing the relation required to instance or subclass of (Q30208840) (diff), which looks like it may be the solution needed. Jheald (talk) 16:06, 21 August 2017 (UTC)
Please re-read the phabricator task. Such a constraint is currently not implemented, neither by the daily reports nor the gadget. While experimenting is desirable, I don't think we should change these constraints back and forth just because you attend some work shop the day after tomorrow.
--- Jura 16:22, 21 August 2017 (UTC)
@Jura1: The workshop was the day before yesterday.
IMO it's better to have a statement that accurately expresses the constraint required, even if that value is not currently understood, and so the constraint is not currently implemented; rather than specify a false constraint just because it can be implemented, which causes people to put false statements on the data in order to make false constraint warnings go away.
If necessary, as D1gggg suggests, we can implement instance or subclass of (Q30208840) as a custom constraint, until the centrally-maintained constraint machinery can take over. Jheald (talk) 16:49, 21 August 2017 (UTC)

I suggest leaving instance or subclass of (Q30208840) on it for the moment, even if the constraint mechanism doesn't currently understand that value, so can't enforce it; and meanwhile add encouragement to so that soon it does get understood and acted on. Jheald (talk) 16:21, 21 August 2017 (UTC)
So @Yair rand:, I just imagined the (entirely appropriate) chain mayor (Q30185) subclass of (P279) public office (Q294414) , subclass of (P279) position (Q4164871) did I ?
And your nonsense of insisting on writing mayor (Q30185) instance of (P31) position (Q4164871) when (i) mayor isn't a position -- it's a class of positions; and (ii) the P279 chain already expresses this.
Fine, let's see what the rest of the community thinks, if you really are determined to persist with this nonsense.
External input requested at Wikidata_talk:WikiProject_Heads_of_state_and_government, essentially as to whether items like mayor (Q30185) are an instance or a subclass. Also items like Mayor of London (Q38931), since you appear to have restored a constraint (diff) that all values for P39 statements need to have a subclass of (P279) set -- which seems completely crazy to me. "Mayor of London" is a position, and there is only one of it. Jheald (talk) 22:46, 21 August 2017 (UTC)

A Few More Paleontology Questions

  1. Is information about individual fossil specimens desirable for Wikidata?
  2. Is it possible or desirable to input multiple estimates for some aspect of a fossil specimen or taxon (eg Paleontologist Paul estimated this dinosaur's live weight to be 10 tons but Fossil Hunter Francine estimated it to be 12 tons).
  3. Is there a way to summon or transclude information in Wikidata to Wikipedia (eg could I say in a Wikipedia article "Examplosaurus first evolved during the [wikidataitemfortheageofexamplosaurus]" and have it automatically update with the information from Wikidata?).
  4. Is it possible to specify that the age of a prehistoric animal has a significant range of uncertainty? (eg "Kronosaurus first appeared sometime in the Aptian-Albian range")?

Abyssal (talk) 20:15, 21 August 2017 (UTC)

I changed your request to an ordered list. Now answers:
  1. Not sure if I understand correctly. If you can create items about individual fossil specimens which fulfill the notability criteria, you should in principle be able to do that. If you are unsure whether this is the case, or if we are talking about a really large number of individual fossils, you might want to describe your plans first in more detail here.
  2. You can provide multiple claims for each property, but it would be useful to add serious references according to Help:Sources to each individual claim. It might be useful to work with ranks to perfer one of them over the other (e.g. "most reliable source", "most sources report that value", etc.)
  3. Technically yes (parser functions #property: and #statement:, or Module:Wikidata). However, many communities are somewhat reluctant to allow this.
  4. Properties with quantity data type allow to provide uncertainty intervals by numeric bounds. In case your property expects a Wikibase-Item as value, you might want to use qualifiers such as earliest date (P1319) and latest date (P1326). (I hope that the time values you need are actually possible with these qualifiers).

Annoying announcement

I'm user w:de:User:Silvicola of dewiki and personally didn't ever do any work here in Wikidata. Since a couple of days, on every consultation of the notices kicked out to me, I get the same thank you for my 100th edit here in wikidata. Yet I haven't even an account here and every try to enter here with my SUL account parameters did fail. So did every try to create the corresponding account here. (Please note: I'm presently not really interested to do here any work, I just wanted to get somehow rid of this annoyance.) Upon consulting “my” user contributions here, I found a list of exactly 100 lemma moves in dewiki, which seem all to have triggered corresponding action logged here, perhaps due to some script or so.

I can very well sustain one thank you, but a thank you repeated ad nauseam is too much. I still hope that after my next lemma move in the dewiki main namespace, this senseless repetition will end. But in any case, others must have suffered and will suffer from the same insistance. Perhaps one or the other of them might even think at pushing around abusively article name space lemmas in dewiki or on some other wiki simply to bring this stray automatism to an earlier end.

Trigger once upon arrival at the milestone, but don't trigger upon stay at the milestone. --2003:6A:6D45:500:4838:F7B9:C87F:B544 20:37, 21 August 2017 (UTC)

  • When you move a page in a Wikimedia project that is connected to Wikidata, you automatically perform an edit here to update the sitelink -- without being notified about this edit. Exceptions: the moving user does not have a local account at Wikidata, or they are blocked here (both not the case for you).
  • You have a connected SUL account, as far as I understand this result. The fact that you can (implicitly) edit Wikidata supports this finding.
  • Notifications for milestones are very common in many Wikimedia projects, but they are delivered only once and visible until they are marked as read.
  • I don't think that another page move at dewiki would help here.
  • So the problem seems to be that you can't log on to Wikidata for whatever reason, and you thus cannot successfully mark the milestone notification as read. What does is say if you try to log on?

Wikidata IDs in Openstreetmap

Openstreetmap has had a "Wikidata" key for years, but still most items use a wikipedia key rather than the Wikidata key. This is much less useful. A Wikidata key would be so much more useful.

I recall reading somewhere that mappers were reluctant to bot-fix this, because sometimes Wikipedia articles do not exactly match the linked Wikidata item. Unless I am missing something huge, this is essentially bullshit.

Can anyone with OSM connections push for the simple move of converting Wikipedia links to Wikidata links ?

Ok sorry for the probably fruitless rant, but it's frustrating to see that things that should be so simple are going along so slowly. --Zolo (talk) 19:03, 14 August 2017 (UTC)

well, having some experience trying to convert wikipedia links from another dataset into wikidata links, the actual problem is most likely that the wikipedia link is to a page that *contains* information about the linked item, but isn't exactly about the linked item. For example an OSM entry for a particular building might point to a wikipedia link for the company that operates out of the building, not to the building itself. ArthurPSmith (talk) 19:34, 14 August 2017 (UTC)
Thanks for the input. It does not seem to apply to OpenStreetMap, or at least, it's not supposed to. Per doc [8]
You may tag secondary attributes of the feature by preceding the wikipedia key with the name of the attribute, separated by a colon (:). The value of such a key would be the same as the normal wikipedia key, but referring to the appropriate wikipedia page. For example, operator:wikipedia=en:McDonald's on a McDonald's fast food unit (but don't forget to also tag operator=McDonald's, because the former tag doesn't replace the latter). 
only provide links to articles which are 'about the feature'. A link from St Paul's Cathedral in London to an article about St Paul's Cathedral on Wikipedia is fine. A link from a bus depot to the company that operates it is not.
I should admit it cites the following (that 'applies to almost no case'), that more or less contradicts the above requirement:
One example where it is appropriate to provide additional explicit links to articles in secondary languages is where the subject is included in an article on a broader subject in the secondary language, for example to the English article which the particular museum in France while French wikipedia has only wikipedia:fr=Monuments et sites de Paris. In another example the structure of subjects in articles cannot be matched 1:1 with interlanguage links (or maybe there are several articles for the same object). In these circumstances use the format wikipedia:lang=page title for the secondary languages.
In any case, that seems like a secondary concern. Would seem much more productive to just upload all Wikidata ids and clean up the few problematic cases afterwards. --Zolo (talk) 20:24, 14 August 2017 (UTC)
Wouldn't it be possible to match OSM node types to Wikidata classes, so that a bot could convert Wikipedia links to Wikidata ids only in the case where the node type and the item type match? We already have OpenStreetMap tag or key (P1282) that could be used for that. Intuitively, that would already cover a decent number of cases, and would be pretty safe. But I can imagine there are cases where the type mismatch is spurious and the Wikidata id should be added anyway. − Pintoch (talk) 09:25, 15 August 2017 (UTC)
My knowlege of OSM is rather shallow, but I think wikipedia|wikidata links should rather go to shapes or ways than nodes. That's also where I have usually seen them (I don't know how to get real states about that).
I suppose we could try a filter by class, but what I see is OpenStreetMap tag or key (P1282) are not subclasses of geographic entites, so that seems rather hard to use [9]. Anyway, if a Wikidata link in OSM is wrong, chances are the Wikipedia link is wrong as well and should be deleted anyway. --Zolo (talk) 10:15, 15 August 2017 (UTC)
"push for the simple move of converting Wikipedia links to Wikidata links": You are far from the first person to ever suggest this to the OSM community. But for many reasons, the OSM community is very wary of massive bot editing and will reject any such proposal if the result is less than 99.9% correct. For example, there are many OSM objects that point to a Wikipedia disambiguation page instead of to an actual article (because things move around in Wikipedia). So blindly adding a Wikidata tag pointing to a Wikimedia disambiguation page Wikidata item is a huge no-no even if it would result in relatively few false-positives. Of course a bot can learn to avoid auto-tagging disambiguation pages but that is just one example; there are potentially many other possible problems. As far as I can tell, the current OSM consensus is to let mappers update/add the Wikidata tag slowly but surely instead of letting a bot do the job.
Anyway, here are two posting to the main OSM mailing list by User:Yurik (senior software engineer at the Wikimedia Foundation) to help add Wikidata tags to OSM objects: [10] and [11]. So there's already an ongoing effort to essentially do what you want. You should also read his OSM Wiki page about OSM–Wikidata questions to get an overview of the many problems of further interlinking OSM and Wikidata. —seav (talk) 00:12, 18 August 2017 (UTC)
I realize [12] has not been mentioned in this thread yet. It is a great app, give it a try! − Pintoch (talk) 06:09, 18 August 2017 (UTC)

I described my efforts to merge OSM and Wikidata in the same SPARQL database. As seav mentioned, linking to disambigs is one of the problems, so my service helps find it with a query (still requires manual fixing), as well as many other similar queries. Any help to actually fix the data is welcome. At some point, I hope it integrates into MapRoulette challenges as well. --Yurik (talk) 16:50, 18 August 2017 (UTC)

@Pintoch, Seav, Yurik: ok thanks. The thing is those wrong links are basically already there in the form of wrong Wikipedia links. If the OSM community could agree that the wikipedia key is obsolete, we could upload all Wikidata links, and then clean them up using Yurik's tool. It would not really add new errors (except when the wikipedia sitelink is wrong, but that's not catchable through Sparql anyway). It seems a lot simpler than dealing with Wikidata keys + Wikipedia keys | candidate Wikidata keys. But of course, that supposes that the OSM would agree with drop maintenance the Wikipedia key in favor of the Wikidata key. But obviously that implies that the OSM community agrees to focus on Wikidata instead of Wikipedia.
Well I suppose that with tools like things can go a bit faster, until now I was using Wikidata ids I need directly through the map, and that's painfully slow. FYI, frwiki is now using the OSM wikidata link to get the geoshape in the infobox, like in fr:Château de Southsea. --Zolo (talk) 15:46, 20 August 2017 (UTC)
“But of course, that supposes that the OSM would agree with drop maintenance the Wikipedia key in favor of the Wikidata key.” This has also been suggested to the OSM community. While I personally agree with this because Wikidata QIDs are more stable than Wikipedia article titles, the general sentiment of the OSM community is that they prefer using the wikipedia=* tag instead of the wikidata=* tag since it is more "user-friendly" for mappers to add. Most OSM users don't understand Wikidata, much less how to find the QID for the correct concept that matches the OSM object. (For example, some people have wrongly tagged every McDonald's store in a locality in OSM with the Wikipedia article on the company/brand.) So it will be hard to convince OSM users to add wikidata=* tag instead of or in addition to the wikipedia=* tag. As both a Wikidata and OSM user, I personally try to add wikidata=* tags whenever I can. —seav (talk) 16:10, 22 August 2017 (UTC)

Limit edits to English language label of properties to logged-in users?

Looking at edits by anons of the last 30 days, it seems that most edits are either vandalism, vandalism reversal or people mistaking the property label for the value to be entered. The few edits that could actually be considered appropriate didn't persist either.

I'd suggest that we try to set up an edit filter that blocks anonymous edits to English labels on properties.

Bonnie & Clyde (cont.)

Hi I made some changes to Help:Handling sitelinks overlapping multiple items and I think we need more examples of the issue as well as the possible relationships. I only scratched the surface and before I go further I would like invite some participation from domain specialists to add their 2c such as the "fruit/tree" people. I remain as ever convinced that is is a docuumentation issue. Thx. Jane023 (talk) 14:18, 19 August 2017 (UTC)

  • As items are less empty, it should essentially become a non-issue for Wikidata. Either the article is about be same as the statements and it can be linked, or should be on another item.
    For Wikipedias, it's mostly a data access question: which item do they want statements and/or sitelinks from. If a Wikipedia wants any stub link to lists at other languages, it could build a feature that does that.
    --- Jura 08:09, 20 August 2017 (UTC)
Yes I agree. My problem with understanding people who want this is that I have trouble trying to figure out what it is that they believe they *can't* do as it is now. It seems to me that there needs to be more help documentation on both sides; the side of Wikidata (what inter-item links can do for search purposes) and the side of Wikipedia (what an infobox, authority control template or other Wikipedia-side functionality is desired). Jane023 (talk) 11:55, 22 August 2017 (UTC)
This is not a valid argument. There is nothing that couldn't be done before Wikidata that can be done now. The issue is not at about what can or can't be done, but instead what can or can't be done easily or effectively or with fewer errors. For example, how can one easily go from to the Wikipedia page that has the most information about her? Without pre-knowledge, any link to another Wikidata item is a possibility. The other direction can be as difficult or even more. Peter F. Patel-Schneider (talk) 04:27, 23 August 2017 (UTC)
Quote: "There is nothing that couldn't be done before Wikidata that can be done now."
not entirely sure about that argument.. could one set interwikis on w:Bonnie Parker (a redirect) or to enwiki from no:Bonnie Parker (an article)? dewiki had an infobox and interwikis on a redirect. Linking enwiki on Q2319886 shouldn't be possible, but somehow someone managed doing it. Obviously, it will be mess once as soone as someone creates an article at w:Bonnie Elizabeth Parker. Due to a still unresolved pagemove bug, this happens occasionally.

Tool for authority control import needed

Every now and then I do import authority control numbers to Wikidata, mostly from VIAF. Take a look at Russian State Film and Photo Archive (Q4398058): it's 9 identifiers, all of them imported by hand. It's a tedious task and I wonder if there is a tool that makes it easier to batch import ids for a particular Q. I don't mean batch import of large datasets, it's a task for the tech wizards. I'm a casual contributor and would like something simple that would allow me to, say, specify the VIAF number and import all the other authority control IDs listed at the respective entry (as in: type 301221768 and automatically import 301221768 as VIAF ID (P214), 0000 0004 0854 4117 as ISNI (P213) and A20924975 as NLP ID (unique) (P1695). It's possible to do by hand, but it's a tedious task and takes ages. (a cross-post from Wikidata talk:WikiProject Authority control#Is there a tool?, @Jneubert: suggested I posted here instead and suggested A starting point could be the "justlinks" function of the VIAF API: (if you know the VIAF id), or for Wikidata item Q4398058 (so you would not even have to build the VIAF URL yourself, if it is present in the item), give you all the links VIAF has. Or is there a tool that does just that already? Halibutt (talk) 08:32, 23 August 2017 (UTC)

Are you a potential WikiFactMine collaborator?

I spent three days on a stall at Wikimania not long ago, and have been updating the Wikidata:WikiFactMine pages here to give a quite full view of the project. The project applies fact mining to recent open access papers downloaded from Europe PubMed Central (Q5412157). Custom sets of search terms called "dictionaries" are used, and recently we have almost completely switched over to SPARQL queries to generate these dictionaries.

If you are interested in trying out our highly-parallel search technology, I'd be glad to help you. So far we have concentrated on plants, diseases and drugs. I'd be particularly interested in increasing what we do in fields of chemistry, where I have worked recently on alloys and terpenoids, and food science.

Bonnie & Clyde problem and links in Wikipedia infoboxes

There is an wikidata item (ab) for wikipedia articles covering several concepts. To distinguish the individual concepts there is one wikidata item for each (item a and item b). Item a is used as a statement value on several other items. A wikipedia is using the data from these items in its infoboxes. It has only an article connected to item ab (article ab), not to a. Infobox data referring to item a should appear with a link to article ab. How can this be realised?

To have a specific example: There is a current situation involving the items historiography (Q50675) (dealing both with historical works and the discipline of studying the ways of writing history - an example of item ab), item historiography (Q30277550) (dealing with the type of work - an example of item a), Histories (Q746583) (an example of an item with item a as statement value) having "historiography" as its genre, the Spanish wikipedia article Historias (Heródoto) connected to Histories (Q746583) and the Spanish wikipedia article Historiography Historiografía connected to historiography (Q50675). People from the Spanish wikipedia (e.g. Xabier) want the infobox-entry "historiografía" to link to Historiography Historiografía. The current "solution" is to use historiography (Q50675) as a statement value for genre. But in my opinion this is rather undesirable as historiography (Q50675) does not represent historiography as a genre (alone). - Valentina.Anitnelav (talk) 08:39, 21 August 2017 (UTC)

This is the job of WP to choose the correct WD item, we can't help them when several subjects are mixed together in one article. Once the item is selected then it is access to the data of others items using lua code. You just need to know the Q number of other items and used them when performing data extraction from WD. Snipre (talk) 11:50, 21 August 2017 (UTC)
Hm... What do you mean with "this is the job of WP to choose the correct WD item"? As far as I see the WD-item they "chose" is all right (Histories (Q746583) for Historias (Heródoto)). I also think that they're absolutely fine with the extracted data. All they are missing now is a link to Historiography Historiografía, or basically a redirect from the non-existent Spanish article for historiography (Q50675) to Historiography Historiografía. Should they just give up fetching these data from wikidata and should I recommend them to provide the genre-information locally? -Valentina.Anitnelav (talk) 18:37, 21 August 2017 (UTC)
Valentina.Anitnelav My comment is about your general example: an article about a and b, where a has a dedicated item in WD and b too. The choice of item a or item b for article ab is under the responsibility of WP contributors. We can't decide here in WD what is the best solution.
Then if you know the item a and the item b, meaning if you know the Q number of these items, you can extract the data from both items in your article (even if your article is connected to only one item) by using parsing functions described in that page. But nobody can tell from WP which are the Q numbers for a and b: you have to find them yourself and then you can use the parser functions instead of the values in order to always be connected to WD. Snipre (talk) 20:24, 21 August 2017 (UTC)
Thank you for the link, but I fear this is not a solution for the problem (not even in the general form): the problem is not how to fetch data from item a and/or item b to display them on article ab. The problem is how to link from an wikipedia article displaying item a (or its label) in its wikidata-generated infobox via item a to wikipedia article ab. Have a look at De bello Hispaniensi. This item should have a link to Historiography Historiografía in its infobox (via "Historiografía", fetched from historiography (Q30277550)), but they can't have the link unless changing item De Bello Hispaniensi (Q783927) in their favour (by changing the value of genre (P136) from historiography (Q30277550) to historiography (Q50675)), but this change is rather undesirable for wikidata as historiography (Q50675) is ambiguous and historiography (Q30277550) is the item for the genre. -Valentina.Anitnelav (talk) 21:00, 21 August 2017 (UTC)
I agree that there is a real problem here. Wikidata items are about a single (possible composite) thing. Wikipedia pages, and Wiktionary pages, may be about multiple things that are related in a multitude of different ways. It thus seems that site links should be many to many per sister project and also be able to be to fragments of a page. For example, the Wiktionary page for tree has at least four corresponding Wikidata items, each of which should site link to this one page (and better to the correct definition in the page). I ran across this problem with respect to several kinds of products and was putting together a long argument for loosening the restrictions on site links when I found this and other discussions of the problem. Peter F. Patel-Schneider (talk) 03:55, 23 August 2017 (UTC)
Peter, I partly agree and partly disagree here. Agree: The alignment of individual Wikipedias and Wikidata is sometimes not perfect, and it would be good to extend it in such cases. One could achieve this by allowing items that have no article on some Wikipedia ("Bonnie") to link to sections of composite articles ("Bonnie and Clyde"). This would allow the creation of a ("weaker") sitelink where there is none now. There are multiple technical approaches to do this, including links to redirects. Disagree: I am against many-to-many sitelinks. The purpose of sitelinks is not to describe what some Wikipedia article is about in terms of Wikidata items, but to describe what a particular Wikidata item is about in terms of Wikipedia articles. Since Wikidata almost always has higher granularity, linking to multiple Wikipedia articles in the same language is not useful for getting a better description of a Wikidata item. Sitelinks are supposed to provide additional "grounding" for Wikidata items, and for this to work it is crucial that they unambiguously identify one concept (this might be a composite of several concepts, if the item represents this composite). Linking a specific Wikidata item to a more general Wikipedia articles or even to a set of articles on different topics will increase conceptual discrepancies across languages. Editors in languages that have only imprecise matches as sitelinks will be likely to add unsuitable content to Wikidata based on their fuzzy understanding of the item's topic. I don't think that there is any way to address Wikidata's fundamental need for maximally precise grounding and at the same time to use sitelinks as a kind of document annotation mechanism to describe the topics of Wikipedia articles. Wikidata is fundamentally not a document annotation database to describe the current content of a particular Wikipedia language edition. This would be more like the envisioned future Wikimedia Commons, where media files can be described in terms of Wikidata items. Both applications have the Bonnie-and-Clyde problem, but they are different in many other aspects. --Markus Krötzsch (talk) 02:23, 24 August 2017 (UTC)

Making mass changes

I've being doing some clean-up of data on listed buildings and scheduled monuments in the UK in preparation for Wikipedia Loves Monuments UK 2017. The query I've been using identifies buildings whose coordinates are not in the named administrative area. For example, 1, Bridge Street (Q26578136) has the property located in the administrative territorial entity (P131) set to Richmond (Q7330735) (a place in South Yorkshire, England), when it should be Richmond (Q1009324) (a town in North Yorkshire, England).

It's easy enough to make the change in one item using the standard user interface. However, I've found 300+ items that require exactly the same change to the located in the administrative territorial entity (P131) property. Are there any tools/bots/scripts around that would make this sort of repetitive change easier and quicker?

If not, does anyone fancy creating a tool that can manage this sort of change with a batch command file or a bot running in the background? Cheers Robevans123 (talk) 19:41, 21 August 2017 (UTC)

Sounds like you are looking for Petscan. If you query your items with the SPARQL option and log on to Widar, you'll see an input form to batch-edit the items returned by the query. You can add and/or remove claims in a single run. --MisterSynergy (talk) 20:04, 21 August 2017 (UTC)
Thank you - that looks promising - I'll give it a go. Robevans123 (talk) 20:21, 21 August 2017 (UTC)
@Robevans123: I don't know to what extent you may already have met them, but if you have the means to identify large numbers of edits you want to make, two invaluable tools are QuickStatements and QuickStatements 2. Both of these can rapidly create large numbers of statements, as specified from a (spreadsheet-style) set of tab-separated lines. The original QS has the better documentation page; but QS2 has much better previewing of what it's about to do, and also adds the ability to remove statements.
From what you already have, it should easy to create such a set of statements for QS2 to remove, interleaved with a corrected set for QS2 to add.
One thing to note is that the statements are re-created from scratch, so you should look out for any existing references or additional qualifier clauses, as you will need to explicitly include these in the directives for the new statements for QS2 to make.
On a different note, I'm quite excited to see you working on this data. Previously quite a lot of the located in the administrative territorial entity (P131) statements have localised items to only quite a crude level (eg county level, or perhaps district level). But I believe the data generally identifies LBs and scheduled monuments to a parish level. Our coverage of civil parishes in England is now to in the 90%s (or was, the last time I looked, a few months ago). So, if you're cleaning up this data, has it been possible to reflect that potential for better localisation, typically to CP level ? Jheald (talk) 21:38, 21 August 2017 (UTC)
@Jheald: Yes - I've used the original QuickStatements - but had discounted that as only been good to add statements. I had a look at QS2, but didn't realise you can use it to delete statements, and couldn't even work out how to enter statements - where do you enter the commands?! Is the syntax the same? Very frustrated!
Definitely want to refine the listed building/scheduled monument data. Quite a few don't have any located in the administrative territorial entity (P131) statements, and the descriptions leave a lot to be desired. I think I've fixed most of the ones that had England as the admin area... Definitely best to get down to the civil parish level where the data is available.
