"Search" does not return the obvious one

When I Search, WD does not return the most obvious hit (i.e., the one I am expecting). Searching "Horse" (lang=English) [1], the top-3 results are:

Vale of White Horse (Q1540110)

Dark Horse Comics (Q373933)

horse breed (Q3745054)

Why is not horse (Q726) in top?

(I'm sorry if this is a repeated point, but ay me searching this page makes it recursive ;-). And also consider the date). - DePiep (talk) 22:33, 1 April 2018 (UTC)

Problem with a property

Nominis given name ID (P4284) in format as a regular expression (P1793) say \d{2,3}/([a-z]+) but Tommy (Q1272055) has 6305/Tommy as ID. It is valid but does not validate the regex. What should be done in a case like that? Is it simply modified? --Metrónomo (talk) 05:40, 3 April 2018 (UTC)

How to define the location a report is about?

If a report or paper is about a geographic area, how to define that? I've looked at narrative location (P840), geography of topic (P2633) and applies to jurisdiction (P1001) but they all seem too specific. Is there any other property that could be used for this? Pauljmackay (talk) 07:36, 2 April 2018 (UTC)

@Pauljmackay: How about main subject (P921)? --Okkn (talk) 10:26, 2 April 2018 (UTC)

@Okkn: Yes that was the most obvious candidate, except I dont think its ideal because its more about defining a restricting scope, rather than defining what the subject of a report is about. Pauljmackay (talk) 16:24, 2 April 2018 (UTC)

You can use of (P642), as in "Birds of Portugal", "Snails of the Severn Estuary". See, for example, Fauna of New Zealand (Q21385461). Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:16, 2 April 2018 (UTC)

Classifiying knots

I checked some knot items and all used instance of (P31) to classify them. Based on one of my earlier questions about use of subclass vs instance of, is it correct to suggest that knots should use subclass of (P279) instead? Because for any knot there could be many "instances". My understanding is that there is a preference for instance of to only be used for things that only have a single instance. Pauljmackay (talk) 19:29, 31 March 2018 (UTC)

Slaves are recorded as Sojourner Truth (Q105180) social classification (P3716) enslaved person (Q12773225), but it lacks the link with devşirme (Q815841). Ghouston (talk) 11:38, 1 April 2018 (UTC)

They were not exactly slaves. Some of them became the highest functionaries of the realm, married the sister of the Sultan. So this is too simple. Thanks, GerardM (talk) 12:26, 1 April 2018 (UTC)

Still, a kind of social class, just lacking an item for the person that corresponds to the practice. Ghouston (talk) 12:43, 1 April 2018 (UTC)

What about Mesih Pasha (Q2480875)subject has role (P2868)devşirme (Q815841) provided that devşirme (Q815841) is a designation of a person and not a social class i.e slave contra slavery. Pmt (talk) 00:18, 2 April 2018 (UTC)

I think that would be like saying Mesih Pasha (Q2480875)subject has role (P2868)slavery (Q8463), it'd still need an item for the class of people who are subjected to it. Ghouston (talk) 01:55, 2 April 2018 (UTC)

Conflict with separate Wikidata items vs. single, combined Wikipedia articles about distinct works

Hi. Is there an established way how Wikidata and Wikipedia handle cases where the Wikipedia article covers several distinct works while standard practice over here is to create separate items for each of those? How are Wikipedia templates on such articles able to pull data about these works from separate Wikidata items?

The reason I'm asking: User:InMontreal alerted me to a problem here. I was adding external IDs for movies and TV shows and came across some anime shows that didn't have their own items yet. When it comes to mangas/light novels and their anime/film/game adaptations, standard practice on Wikipedia (all/most language versions) seems to be to cover them all in one big article. Which means that currently our items in that field are usually a wild mix of statements pertaining to mangas, light novels, animes, video games, etc, and also include external IDs like IMDb ID (P345), AlloCiné series ID (P1267) and Anime News Network anime ID (P1985) for specific works. So I created several new items for anime series and moved all respective IDs and statements for these shows to the new items.

But it seems on various Wikipedias such IDs might be removed after they have been transferred to Wikidata, so the link templates no longer contain them and simply pull the ID from Wikidata. So when you split them into separate items for each work (as is usual on Wikidata), those IDs are also moved to those items and are no longer accessible for Wikipedia templates. Infoboxes also suffer the same problem of course. I hope there's a solution besides just telling Wikipedians to deal with it themselves.

Here's the advice: Help:Handling sitelinks overlapping multiple items --Tagishsimon (talk) 02:03, 24 March 2018 (UTC)

It's curious that the Help article doesn't mention Wikipedia article covering multiple topics (Q21484471) at all. - PKM (talk) 18:53, 24 March 2018 (UTC)

So it seems the "solution" is indeed "just telling Wikipedians to deal with it themselves" :-/ . I mean, it probably isn't a bad idea for Wikipedias to modify their infoboxes to pull their data from other items if needed. But who's going to tell them, since it doesn't seem like the infoboxes on the affected articles are able to do that at the moment?

So, as the guy who created the new items and moved the statements over, I guess I have two options: a) tell two or three dozen Wikipedias they now have to change their link and infobox templates to deal with the changes to a few items I chose to make on Wikidata - although to them, there wasn't really a problem with the status quo that needed fixing. And then I'd probably have to justify the changes in many languages that I don't even speak. Or b) undo my edits and give the whole topic a wide berth in the future - in the hopes that someone with a lot more time, energy and patience will stumble upon this problem and is willing to deal with it. --Kam Solusar (talk) 12:04, 26 March 2018 (UTC)

I don't think the infoboxes on any of these Wikipedia articles worked correctly. If users there are interested, eventually they will figure out how to get the content. Thanks for starting to tackle these few remaining ones ..
--- Jura 12:13, 26 March 2018 (UTC)

I'm not sure that's the best way to handle such situations, since Wikipedians might see it as Wikidata changing/breaking things without giving Wikipedia a warning. And especially on smaller Wikipedias, it might break stuff for a long time until people figure out what happened and find someone to fix the templates. One of the problems User:InMontreal pointed out on my talk page is, that when you move all the statements and IDs to a separate item, there's no indication on the main item why they were removed and where to find them now. Or people might just assume that they are missing and try to add them back (which happens often with external IDs harvested from link templates). I didn't know a good way to indicate "for information about the anime that is also described in the linked articles, see QXXXX", though I just found derivative work (P4969) which looks like it might do the job of at least having visible links on the main item.

Though I'd prefer if there was some kind of outreach to point out the problem to affected Wikidia communities and how to handle it, so not every single community has to stumble on the problem and try to figure it out for themselves. --Kam Solusar (talk) 00:36, 29 March 2018 (UTC)

Sorry but it is not as if Wikidata is new or that practices like these are new. There are plenty of things Wikipedia does that does not make sense from a Wikidata perspective. The problem is also that communication is often broken by Wikipedians insisting on no Wikidata. So outreach sure.. But who is to do this? Thanks, GerardM (talk) 05:53, 29 March 2018 (UTC)

@Kam Solusar: The correct way to do this is to create an item for the franchise like Naruto (Q642), link the article to it and add the anime, manga, light novel, OVA etc items with has part(s) (P527).

Then Wikipedias can create modules to retrieve the correct identifier. --Thibaut120094 (talk) 03:14, 31 March 2018 (UTC)

Thibaut120094: Seems more like a workaround (as the articles' primary topic seems to usually be the manga/light novel series, not a franchise), but if that's the current solution for these cases, guess I'll use it. Though I'm not really looking to take on the task of creating items for all the works covered by those artices/items myself (especially since I don't know all that much about about manga franchises)... --Kam Solusar (talk) 11:58, 3 April 2018 (UTC)

• If there were cases where this seemed to work before, it might worth looking into them in detail. It's likely that they were probably broken in one way or the other, but people just didn't notice (e.g. publication date of a film displayed in the infobox about a print version). To work correctly, infoboxes that are used in articles combining several topics need to do a check on P31 of items they attempt to use data from.
  --- Jura 06:33, 29 March 2018 (UTC)

Yeah, some might have shown false information for quite a while without anyone realizing it (or they realized it and didn't find someone who could help fix the problem). Checking the P31 statements helps, but I imagine there could still be some problems with items that have multiple P31 statements and in cases where there's more than 1 infobox for the same type of work on one page (i.e. a franchise with more than 1 tv show or videogame). --Kam Solusar (talk) 11:58, 3 April 2018 (UTC)

Edinburgh Research Archive - thesis collection data

Hi all, after a hiatus we are returning to look again at importing data on the Edinburgh Research Archive's thesis collection into Wikidata. The ERA has over 20,000 thesis records so we are looking to get the modelling correct - once agreed our Library Digital Scholarship Developer @ChaoticReality: can proceed with the import reasonably quickly. For a refresher on what we originally discussed in November 2017 in Wikidata's Project Chat is here and the Google document with the data model we originally proposed is here.
3 questions arose from our discussions last time:

1. There are 24 (approx) thesis types in the collection. If I create a thesis' item for each type as was suggested e.g. ChM Master of Surgery thesis then is it to be described as P31 Instance of a masters thesis? OR P279 subclass of a masters thesis?
2. Prize essays are a whole other kettle of fish. They seem to be described on Wikidata as scientific article but they can be on any subject I believe and sometimes become thesis dissertations and sometimes not. I wonder if it would not be better for prize essay to have its own Q number? What do you think? A reference to one with some explanation here: here. Gweduni has more info on the Prize essay distinction if you need further info.
3. Finally, Should we also update existing items that don't yet have links? For example Doctor of Philosophy (Q752297) is a subclass of Doctoral Degree (Q849697) but Doctor of Education (Q837184) is not. So should we include statements to make that connection?

For info, all the below are theses.
Subsets of thesis: doctoral, masters, ‘other’.
Doctoral (Level 12 on the Scottish Credit and Qualifications Framework – the highest level)

• DClinPsychol Doctor of Clinical Psychology
• DD Doctor of Divinity
• DDS Doctor of Dental Surgery
• DLitt Doctor of Literature
• DPhil Doctor of Philosophy
• DPsychol Doctor of Psychology
• DSc Doctor of Science
• DVM&S Doctor of Veterinary Medicine and Surgery
• EdD Doctor of Education
• MD Doctor of Medicine
• PhD Doctor of Philosophy
• PhD(P) Doctor of Philosophy by Research Publications

Masters (Level 11 on the Scottish Credit and Qualifications Framework)

• ChM Master of Surgery
• LLM Master of Laws
• MA Master of Arts – although in Scotland MA(Hons) is undergraduate, equivalent to English BA (for info MA(Hons) / BA is Level 10 on SCQF)
• MBA Master of Business Administration
• MEd Master of Education
• MLitt Master of Literature
• MLT Master of Letters
• MPhil Master of Philosophy
• MSc Master of Science
• MSc(R) Master of Science by Research
• MTh Master of Theology

Other:

• Prize Essay

Any pointers, gratefully received. Many thanks, Stinglehammer (talk) 18:01, 28 March 2018 (UTC)

'P279 subclass' is correct. Instance should only be used for a specific thesis with a given title and author etc. If you find missing items or statements as you suggest, please add them as long as they make logical sense; wikidata is always going to be incomplete, it's up to us to help improve it! ArthurPSmith (talk) 19:27, 28 March 2018 (UTC)

┌────────────────────────────────────────────────────────────────────────────────────────────────────┘ I've numbered your questions:

1. Subclass of; per Arthur
2. "would not be better for prize essay to have its own Q number?" Yes, the maxim "be bold" applies
3. yes.

Well that was easy. Thanks @ArthurPSmith, Pigsonthewing:! I'll let ChaoticReality and Gweduni know so we can move this forward. (Gotta love Wikidata discussion threads. Sooooo much easier). Stinglehammer (talk) 21:25, 28 March 2018 (UTC)

Brill, thanks both. We'll be doing a pilot run of ~50 objects in the first instance, so I'll probably post again closer to the time we're ready to do this. ChaoticReality (talk) 13:12, 29 March 2018 (UTC)

@ChaoticReality, Pigsonthewing, ArthurPSmith: Ok

Have created Wikidata numbers for the thesis types now and added on this Google sheet. Items in red are newly created thesis type items. Items in blue indicate there is a one item being used for two thesis types. i.e. Master of Literature (Master of Letters) and Master of Letters (Master of Letters) are both Q1907865 so the master’s thesis is Q51283362 for both. 3 questions cropped up again:

1. Checking with Gweduni that he is happy with this or whether we should separate the two. Thoughts?
2. Prize essay now has its own Q number: Q51282441. Are we happy how it is described? Checking with Gweduni as to what would be an adequate description and statement type for a prize essay.
3. I’ve added that each degree type (e.g. Master of Surgery degree) is a subclass of master’s or doctoral degree etc. but there might be some extra tidying up needed – seems to be a real mix of instance and subclass statements being used to describe each degree entirely differently at present. What should be the main statement modelling/hierarchy we should be working with on these degrees do you think to keep things logical & consistent? Stinglehammer (talk) 11:38, 3 April 2018 (UTC)

Capturing provenance of food

Is there any property used to capture the region or more specific location where a particular food originates from? For example that a pasty originates from Cornwall? There is country of origin (P495) but thats only for countries. There is location of creation (P1071) but that seems more focussed on manufacturing rather than where a food product is originally from. Does this need a new property? Pauljmackay (talk) 11:11, 31 March 2018 (UTC)

There are some claims like Valtellina Casera (Q782709) part of (P361) Lombard cuisine (Q47176), but maybe that's not quite the same thing. Ghouston (talk) 11:33, 31 March 2018 (UTC)

@Pauljmackay: - indigenous to (P2341) is explicitly scoped to include "cooking style", so this would seem a good approach. Just be careful with baklava (Q187495) and Pavlova (Q1419824) ;-) Andrew Gray (talk) 11:53, 31 March 2018 (UTC)

@Andrew Gray: - that seems like a good option except after adding it to Cumberland sausage (Q586591) it flags an issue because the constraints on that property require it to be a dish (Q746549), which wont be true for all food products. Should the constraint be altered? Pauljmackay (talk) 12:22, 31 March 2018 (UTC)

@Pauljmackay: yeah, I think that's the best approach - broaden the constraint a bit. As well as a cooking style we could have indigenously-identified prepared foods, basic foodstuffs, spice, drinks... Andrew Gray (talk) 14:39, 31 March 2018 (UTC)

Might also be useful to note foods etc that have a formally protected en:Geographical indication. There's been an industry initative to produce a worldwide database of these (report), and it looks like the database is usually live here, though just at the moment it seems to have fallen off the net. But here's Google's cache of the first page.

Everything on the list probably ought to have an item, if it doesn't already. Property named after (P138) may also be useful. Jheald (talk) 19:02, 31 March 2018 (UTC)

There is location of creation (P1071) with alias "location of origin" and "place of origin". Current label is more focused on manufacturing, but it was changed in 2014 from "place made", which was an original label in time of proposal.

We have a lot of items about appellation d'origine contrôlée (Q1565828) and most of them use located in the administrative territorial entity (P131), which is not appropriate in my view.--Jklamo (talk) 12:25, 3 April 2018 (UTC)

Academic writing: activity or type of work?

academic writing (Q4119870) has been a confusing item since it has been created. Is this about the activity of writing academic works or is it a type of academic work? I can't read all languages. Sjoerd de Bruin (talk) 11:25, 2 April 2018 (UTC)

I think Wikidata needs separate items for the type of work and the activity of writing such work. I would expect a Wikipedia article to cover both the activity and the work it produces (in fact, I think that it would be hard to separate them in an encyclopedic article). For the sake of useful Interwiki links, I'd keep the article links on the existing work item and create a new linked item for the activity. (For an interesting comparison, see technical writing (Q1193158) [activity] and technical documentation (Q1413406) [work].) - PKM (talk) 21:09, 2 April 2018 (UTC)

Improving the definitions of crafts

The Heritage Craft Assocation defines a "heritage craft" as "a practice which employs manual dexterity and skill and an understanding of traditional materials, design and techniques, and which has been practised for two or more successive generations" (see their Red List). IMHO most of the items that link to craft (Q2207288) are occupations, not the craft (skill, practice) itself. So stonemasonry (Q19794820) is a craft, a stonemason (Q328325) is an occupation or artisan that practice that craft.

Also these crafts and occupations should be subclasses, not instances, along similar lines to my other recent questions :-) What do others think? Pauljmackay (talk) 16:41, 2 April 2018 (UTC)

I agree on separation of crafts and craftspeople. See pottery (Q11642) and potter (Q3400050), tapestry weave (Q29167534) and tapestry weaver (Q21820569). These can be connected using practiced by (P3095). I am less certain about instances vs. subclasses. I think <instance of> is perfectly appropriate for things like crafts and occupations. If stonemason (Q328325) isn't an instance of an occupation, what would be? - PKM (talk) 20:54, 2 April 2018 (UTC)

Maybe this overview helps? Multichill (talk) 21:52, 2 April 2018 (UTC)

On instance of (P31) versus subclass of (P279), a question I find is often quite useful is: can one imagine a specialist form of this activity or thing. So one could imagine "Chinese fan-making" or "18th-century fanmaking" or "paper fanmaking", suggesting the activity should be a class. As for the occupation, I am less convinced that one would identify "18th-century fanmaker" (ie a maker of 18th-century fans) as a distinct occupation, so I would be minded to keep it as an instance, unless/until a more specific instance gets created. Jheald (talk) 09:41, 3 April 2018 (UTC)

@Jheald: thinking more on that aspect, I wondered if a sensible structure is that a stonemason (or whatever) is an instance of an "occupation" and a subclass of "artisan". So Joe Bloggs is a stonemason or artisan, but has an occupation of stonemason. Pauljmackay (talk) 10:33, 3 April 2018 (UTC)

Except that, on Wikidata, Joe Bloggs is a human (Q5), and stonemason is not a subclass of person. artisan (Q1294787) we identify as a subclass of profession (Q28640), in turn a subclass of occupation (Q12737077); so making stonemason a subclass of artisan (Q1294787) makes it a subclass of occupation (Q12737077) as well. Jheald (talk) 11:20, 3 April 2018 (UTC)

@Jheald: currently I see artisan (Q1294787) is an instance of profession (Q28640), so does that need changing to subclass? Pauljmackay (talk) 11:47, 3 April 2018 (UTC)

@Pauljmackay: Perhaps not: Reasonator says we have 489 instances of profession (Q28640), only 8 subclasses. Passing this to the crowd, to see what anybody else thinks. Jheald (talk) 12:52, 3 April 2018 (UTC)

There’s discussion on this point on the talk page of profession (Q28640)! which I would characterize as “unresolved”. Personally, I like the distinction filmmaking occupation (Q4220920) = subclass and cinematographer (Q222344) = instance. - PKM (talk) 20:38, 3 April 2018 (UTC)

2 communities merge to 1

Before 2005 two communities (villages): Kato Amiantos (Q48413729), Pano Amiantos (Q47004149). After that the two communities merged to one, new community with the name Amiantos (Q6377735). I used

⟨ Amiantos (Q6377735)    ⟩ has part(s) (P527) ⟨ Kato Amiantos (Q48413729)    ⟩

and

⟨ Amiantos (Q6377735)    ⟩ has part(s) (P527) ⟨ Pano Amiantos (Q47004149)    ⟩

to show this. Is that correct? The new community is not split to two areas...

And how to show that Kato Amiantos (Q48413729) merge with Pano Amiantos (Q47004149) and create Amiantos (Q6377735)? I means in Kato Amiantos (Q48413729) item.

Notification of Rapid Grant proposal for Wikidata QuickSheets expansion for P172

FYI, I wanted to let you all know that I have submitted a Rapid Grant proposal to further develop software that will semi-automate the process of moving data from Wikipedia to Wikidata. The tool is designed to be accessible to those without programming experience by using simple article lists to generate spreadsheets for human evaluation. This builds on work done as part the Art+Feminism campaign, which is detailed at our workplan but this grant is not for A+F related work. I welcome your feedback on the proposal. --Theredproject (talk) 21:25, 3 April 2018 (UTC)

Are empty categories allowed on Wikidata?

Hi all

I'm working on a way to record datasets that are being and have been imported into Wikidata and it will involve some use of categories. However some categories will be empty when the tool is published and then be populated later, and could possibly at some points be empty again. Are empty categories allowed on Wikidata? Is there a way to signify that even though the categories are currently empty they will be used in future? If someone comes and deletes the categories thinking they are helping tidy up it will break the tool and this is something I would very much like to avoid.

Thanks

--John Cummings (talk) 12:35, 31 March 2018 (UTC)

Unless if they are registered in Special:TrackingCategories or as Babel categories, I  Strong oppose including them, because they are just e.g. "Category:Articles for deletion since 2009", who will ever dig histories of them via this site? --Liuxinyu970226 (talk) 13:22, 31 March 2018 (UTC)

@Liuxinyu970226: can you tell me how to register them in Special:TrackingCategories? It would be around 15 categories (including all sub categories) in total. --John Cummings (talk) 14:49, 31 March 2018 (UTC)

@John Cummings: That depends on developer level, you can see phab:T35033 (tracking task) on ideas of it. --Liuxinyu970226 (talk) 14:55, 31 March 2018 (UTC)

Liuxinyu970226's objection does not make much sense to me. "I oppose because they'll be eg Category:Articles for deletion since 2009 and who will look at them?" What? 1. They won't have such a name, and the name is largely irrelevant 2. no-one is being invited to dig through them: categories have other uses than being lists that people look through 3. no harm is adduced in your objection 4. we can make the assumption that JohnC is trying to do good things with them. What is not to like? Meanwhile they are not tracking categories - if I understand the rubric of that page correctly, nor are they Babel categories. Registering them as such seems pointless and damaging. I don't know the category system in wikidata well; I recall en.wiki has a "do not throw me away if empty" template designed for exactly the situation outlined by JC. So, perhaps I might ask for an articulation of credible issues that might arise from JC's proposal? --Tagishsimon (talk) 18:19, 31 March 2018 (UTC)

@Tagishsimon: Your "support" makes nonsense either, if a category page was just created by LTA e.g. Kagemusha (影武者), then how can investigation of their spam history must also likely to be a main work of this site? --Liuxinyu970226 (talk) 23:56, 31 March 2018 (UTC)

JC is talking about creating categories, and is not talking about crearing items denoting a category. "how can investigation of their spam history"... what on earth has this to do with the question in hand. You might as well ask, what if JC creates chocolate categories and they melt. We've established there is precedent for empty categories in wikidata, and have yet to hear any sensible or comprehensible issues from you. If you have anything practical to say, please do so. --Tagishsimon (talk) 00:02, 1 April 2018 (UTC)

• I am the one who deletes most of the empty category items these days, mostly based on Wikidata:Database reports/to delete/empty category items. We have a couple of hundred new cases each week, due to Wikipedia category deletions that leave back empty category items here at Wikidata. Deletion of those items is not very complicated in any way, but it consumes quite some time if done properly.
  Since the most important purpose to have categories linked to Wikidata at all is to provide interwiki links, empty category items appear indeed somewhat unnecessary and I'd prefer not to start with such exceptions. If however the community now comes to agreement that we should accepte empty category items for a while, I could try to avoid running into them (provided I have a list of affected items) while working down the queue. However, these kinds of exceptions do not scale at all, and I'd probably stay away from category deletions if a second editor requested something similar.
  An alternative would be to create the categories already at Wikipedia and link them to the items; however, there is a comparable risk that some editor nominated them for deletion "because they are empty". Same problem technically, just that it had to be dealt with somewhere else... Not sure what to think of this :-) --MisterSynergy (talk) 20:35, 31 March 2018 (UTC)

@Tagishsimon: @MisterSynergy:, thanks very much, does the 'don't delete me, I'm useful' template (I think on Commons its called a maintenance category?) exist already?

So to explain what I want to use them for, I want to create an updated version of Wikidata:Data_Import_Hub where each dataset has its own page because it is becoming popular and very crowded. The pages for each dataset would be organised by using some broad categories around if the dataset import is 'in progress', 'needs help' or is 'complete' and then split by some broad topics (copying the Mix n' Match topics) and then a few categories for things like data type (e.g spreadsheet or list). The user can then explore the datasets by running searches for more than one category at a time e.g all the 'in progress' datasets about 'art'. These searches would all be premade using cirrussearch and the user would just click the button.

When the process first gets up and running a small number of the categories will be empty and its possible that some categories will be empty from time to time because there is nothing fitting that description e.g imports that need help. I just don't want categories to get deleted during this window which would break the system. In total the system would have maybe 30 categories and my guess is perhaps 2 or 3 would be empty from time to time.

There's a rough draft of the user interface at User:John_Cummings/Wikidata_Import_Hub_draft which may explain things a little better.

Thanks

--John Cummings (talk) 20:50, 31 March 2018 (UTC)

After reading your reply I am not sure whether I completely understood your opening comment; so in case my previous comment appears offtopic, don't worry any longer.
Do you speak about categories in Wikidata? If so, there is {{Administrative category}}, and there is Special:UnusedCategories to have an overview of currently empty categories. I don't think that there are many admins looking for those, but maybe it would be useful to secure them with a permanent marker, or a link to a page that explains why this category could be (temporarily) empty. --MisterSynergy (talk) 21:07, 31 March 2018 (UTC)

I hope you'll be bold and go ahead, John, with {{Administrative category}} and a pointer to an explanation of the cats as your friends. --Tagishsimon (talk) 21:55, 31 March 2018 (UTC)

Standardizing historic patents

I work on historic patents and would like to standardize our ontology for them here. There are millions of them, and for those before 1900 no standard global source to search for them. Wikidata can do that. Is anyone else interested in working together on this?

Probably a patent item should have:

• instance of patent (Q253623)
• country where filed -- but not necessarily a currently-existing country; e.g. in the German states before 1870 there were patent systems. Presumably the WIPO code is appropriate to mark the country of a patent, but that would require some kind of property proposal. Property talk:P3068
• discoverer or inventor (Property:P61) -- there can be multiple inventors
• applicant(s) -- not always the same as the inventor(s), notably if a company filed the application, or the inventor died and someone else is filing
• title -- a string
• filing date is not the same as grant date; it would be good to store these distinctly because they have different historic meanings. The filing date is when the technological claim was made by the patent-filer, and the grant date is the date the government accepts and approves it officially. Both have legal importance.
• Wikisource id should be used when a patent is transcribed there. it's infinite work but a good idea in some cases. Good text is not always available and Wikimedia can help.
• patent number -- a Wikidata standard for this exists: (Property:P1246) -- however format is restrictive, requiring format like US891393. Usually this works but in some historical cases there are letters in the 'number' (1BB##### in 19th century France, though possibly the 1BB can be left out), and there may be cases in which there is no proper number, so this item is optional but will be there in >99% of cases. Note that patent number in this format does not include year and so is not unique e.g. in Great Britain numbers were reused year after year.
• publication date, optionally -- historically this was sometimes later than grant date
• A standard naming scheme for the items is desirable in those cases that they are not named distinctively, e.g. by the title. Something of this kind has been unambiguous in my research so far: Patent plus country plus year plus number, e.g. "Patent US 1906 821393"

What to do if a company sell different divisions to different companies?

Should I fill in followed by (P156) with the names of all the various buyer companies?
Or should I create one item for every department of the company and fill in the respective followed by (P156) properties with the organization that bought that division?--Malore (talk) 15:16, 5 April 2018 (UTC)

I think creating items for the divisions that were sold, if they pre-existed the sale, is a good idea. There may be other aspects of this to consider - for example you could create an item for the event itself, if it was notable enough. ArthurPSmith (talk) 16:16, 5 April 2018 (UTC)

If you mean subsidiary (Q658255) the best is to:

• create item about subsidiary
• fill parent organization (P749) with selling company and end time (P582) qualifier
• fill parent organization (P749) with buying company with start time (P580) qualifier and set-up preffered rank
• add subsidiary item to selling company to has subsidiary (P355) with end time (P582) qualifier
• add subsidiary item to buying company to has subsidiary (P355) with start time (P580) qualifier.

Individual tree

In General Sherman (Q152482), there is instance of (P31) = Sequoiadendron giganteum (Q149851), but it has a notice that indicates that there is some kind of problem with this statement. If we have an remarkable tree (Q811534), how do we correctly indicate the species of that tree? Thanks in advance, Paucabot (talk) 08:15, 5 April 2018 (UTC)

This looks fine to me. Perhaps we need to change the constraints on instance of (P31) to also allow for the taxonomic hierarchies? ArthurPSmith (talk) 16:49, 5 April 2018 (UTC)

I made Sequoiadendron giganteum (Q149851) a subclass of tree (Q10884), now it doesn't complain. It's no worse than Homo sapiens (Q15978631) being a subclass of omnivore (Q164509). Ghouston (talk) 05:15, 6 April 2018 (UTC)

Technically some humans aren't omnivores, and some Sequoiadendron giganteum (Q149851) (like seeds and saplings) aren't trees. Ghouston (talk) 05:18, 6 April 2018 (UTC)

There would be accurate items they could be sub-classed to, organism (Q7239) at least. Ghouston (talk) 05:23, 6 April 2018 (UTC)

I've been wondering about that too. It makes sense that target of instance of (P31) for every item should be a subclass of something, i.e. it uses subclass of (P279) (see here), and it makes sense that every individual organism is an instance of some taxon, which is a class of organisms. Taxon items however generally avoid using P279, they use parent taxon (P171) to build the class hierarchy. P279 could be used in addition to "parent taxon", but then for many cases one would seem redundant to another, e.g. why would we indicate every species in some genus as subclass of "tree" (or some other organism), while this applies to all species in this genus. I see that using P279 instead of P171 was considered in the past, but P171 stayed in use, in my opinion, judging by the RfD, without much of a good reason. While P171 is a well-defined property, I don't quite get it how is this different from any other classification that works out more or less fine using P279, including for cases when an item is part of multiple classifications. And property label ('subclass') being homonymous seems to be of little importance, say, if English label isn't homonymous then it may be in some other language or vice versa, and I assume users would generally check the description before applying a property that they are unfamiliar with. Perhaps, in light of this tree issue and data model model in general, using P171 should be finally reconsidered? 90.191.81.65 06:23, 6 April 2018 (UTC)

That discussion about P171 provides the right thing to set subclass of (P279) to: the item for the nearest parent taxon. So Homo sapiens (Q15978631) can be a subclass of Homo (Q171283) and Sequoiadendron giganteum (Q149851) a subclass of Sequoiadendron (Q14707792). That does make parent taxon (P171) seem redundant. You can check taxon rank (P105) to work out if a particular subclass or superclass is a taxon, or something random like omnivore (Q164509). Ghouston (talk) 06:52, 6 April 2018 (UTC)

Or check instance of (P31) taxon (Q16521). Ghouston (talk) 06:56, 6 April 2018 (UTC)

Piano, per favore

Hello. I can not revise my edits all the time. Slow down, please. Compromises are always needed...

MinDat blocks, if you use it as a reference for valid minerals more than 2 times/day.

Misocam blocks [Mineralogical Society of America (MSA), Handbook of Minerals (HOM)], if you use it as a reference more than half a dozen times/day during ten days.

Nowadays, I use webmineral.com, rruff.info/ima, mineralienatlas.de and many things are implied on 'The IMA List of Minerals'.

Property 'as' got deprecated, but 'object has role' is not acceptable as a qualifier of 'instance of'. Many valid minerals were discovered after they got synthesised first.

All valid minerals need to be an 'instance of' 'mineral', otherwise 'chemical formula' is not acceptable.

Property 'named after' (eponym), qualifier 'subclass' is not acceptable. But Wikipedia labels are substantives, sometimes adjectives and verbs are needed too.

And when you have the paid trolls who try to rewrite history...

Military badges and insignia

I've sketched in a class tree between breast badge (Q799000) and Marine Aerial Navigator insignia (Q6763987). There is work needed in this area to build out all countries and all branches of service. There are many items and categories already in Wikidata, but they don't seem to have subclass statements or be linked to each other. It's possible cleaning this up could be automated using Wikipedia categories as a starting place. But that's not part of my skill set, and military insignia aren't my area of expertise or particular interest. So far I have not distinguished between the concepts "badge" and "insignia", since they seem to be interchangeable on Commons. My understanding is badge=physical object and insignia=symbol, but I don't know that the military use the terms in this way. Anyway, does anyone want to take on expanding this structure? - PKM (talk) 19:39, 7 April 2018 (UTC)

Add new data to Wikidata

I would like to add the term "WoeKO" into the database. I have the history of the individual and links. How can this process work?  – The preceding unsigned comment was added by Woeko (talk • contribs) at 8. 4. 2018, 05:49‎ (UTC).

@Woeko : please check out Wikidata:Notability and let us know if "WoeKO" meets the test. If so, an item can be added via the "create a new item" left-side menu link. --Tagishsimon (talk) 06:14, 8 April 2018 (UTC)

Should website and company be separated?

There are a number of items like Internet Archive (Q461) and YouTube (Q866) that represent both the website and the organization. Should this items be split?--Malore (talk) 20:08, 2 April 2018 (UTC)

Yes. An interesting conundrum is which one the existing item should be used for. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:10, 2 April 2018 (UTC)

We also have the same problem with streaming services like Netflix (Q907311), Hulu (Q1630304), Amazon Prime Video (Q4740856) or Crunchyroll (Q1142035). --Kam Solusar (talk) 12:03, 3 April 2018 (UTC)

Definitely yes. Some items were already splitted (like X (Q918) vs Twitter, Inc. (Q1390577), Google (Q95) vs Google Search (Q9366) or Facebook (Q355) vs Meta Platforms (Q380)). But it is not easy to determine where sitelinks belong, as most of the sites are covering both concepts (website/service and company). In a case of X (Q918) and Facebook (Q355) most of sitelinks are on "service" item, while for Google (Q95) on "company" item.--Jklamo (talk) 12:39, 3 April 2018 (UTC)

@Pigsonthewing, Kam Solusar, Jklamo:I noted a problem: if both the items have an official website (P856) property linking to the same URL, there is a property constraint violation. What to do?

Create a new property (renaming official website (P856) in "official website URL") that links to the item representing the official website instead of the website itself?

Or add statement is subject of (P805) filled with the item representing the website as value of the official website (P856) property inside the company item and change the property constraint so that it is allowed more than one item linking to the same URL, but only one without a statement is subject of (P805) qualifier? --Malore (talk) 11:43, 5 April 2018 (UTC)

I would say yes as YouTube, LLC. And YouTube.com are two very different things, in many cases the company could also have separate products unrelated to the service that gave the company its name or vice versa (E.G. Google mentioned above). -- 徵國單  (討論 🀄) (方孔錢 💴) 09:09, 8 April 2018 (UTC)

How can I express search results as an external link?

Hi all

I'm trying to create something that uses links to search results with include and exclude the results of multiple categories, is it possible to express these links as internal links? E.g

https://www.wikidata.org/w/index.php?search=&search=incategory%3A%22Archives+datasets%22+incategory%3A%22Datasets+by+progress%22&title=Special:Search&go=Go&searchToken=4on3a24isms4ii04x8nmz7zqj

John Cummings (talk) 15:40, 4 April 2018 (UTC)

Given the complexity of such a linking, I would say no. But a template can help with it. Matěj Suchánek (talk) 07:21, 5 April 2018 (UTC)

@Matěj Suchánek:, do you know if this template exists on any Wikimedia projects? I think I can make it work with just the links but it will complex for other people to edit. --John Cummings (talk) 13:00, 5 April 2018 (UTC)

Prime factors?

I wonder whether there is any appropriate way to represent prime factors of a number in Wikidata, e.g., 89 681 and 96 079 for Jevons' number (Q1100748) or 37 975 227 936 943 673 922 808 872 755 445 627 854 565 536 638 199 and 40 094 690 950 920 881 030 683 735 292 761 468 389 214 899 724 061 for RSA-100 (Q15990637). Alternatively, maybe a property can be created for the identifier in the factordb (Q1391719)? -- IvanP (talk) 10:18, 8 April 2018 (UTC)

See: Wikidata:Property proposal/KIT Linked Open Numbers ID. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:46, 8 April 2018 (UTC)

You know that this project (Linked Open Numbers) is an April fools joke? But you still would like Wikidata to link to it? It does not even provide a prime factorization to all composites in it and 1 is displayed in prime decompositions (e.g., “Prime factors: 1 * 2 * 3 * 7” for n42, though in Semantic forms and Graphite, we only see n2, n3 and n7). -- IvanP (talk) 12:09, 8 April 2018 (UTC)

Fashion or style "based on" another

I have sources that state that the homburg (Q697666) is "based on" the Tyrolean hat (Q694050). (I have also run into this for other types of clothing.) Using based on (P144) for this relationship throws a constraint violation since clothing and its subclasses aren't currently works. I think the best way to resolve this is to make clothing (Q11460) a subclass of work (Q386724). Thoughts? - PKM (talk) 01:55, 6 April 2018 (UTC)

Decorated by

How can I show that an interior have been decorated by an artist?. One possibillity is to use the same solution as done with the Sistine Chapel (Q2943) where the item Sistine Chapel ceiling (Q844675) has been created as an item with Michelangelo (Q5592) as creator (P170). But doing that I would have to create an new interior item for each building. Pmt (talk) 17:25, 8 April 2018 (UTC)

Is this out of the question? "Of" is designed as a "qualifier stating that a statement applies within the scope of a particular item".

⟨ Sistine Chapel (Q2943)    ⟩ creator (P170) ⟨ Michelangelo (Q5592)    ⟩
of (P642) ⟨ interior (Q2998430)    ⟩

--Tagishsimon (talk) 19:38, 8 April 2018 (UTC)

Could we use the qualifier applies to part (P518) here: <creator> [name] <applies to part> interior decoration (Q5875045)? Or possibly significant person (P3342) and object of statement has role (P3831): <significant person> [name] <object has role> interior designer (Q2133309)? - PKM (talk) 20:39, 8 April 2018 (UTC)

That's better ...

⟨ Sistine Chapel (Q2943)    ⟩ creator (P170) ⟨ Michelangelo (Q5592)    ⟩
applies to part (P518) ⟨ interior decoration (Q5875045)    ⟩

--Tagishsimon (talk) 20:46, 8 April 2018 (UTC)

Thanks Pmt (talk) 21:23, 8 April 2018 (UTC)

That formulation gives us a property constraint issue on creator (P170) not allowing applies to part (P518) as a qualifier. I'm inclined to argue for the constraint to change. --Tagishsimon (talk) 22:00, 8 April 2018 (UTC)

Is there a limit to the number of references?

Is it possible to have too many references for a statement? I ask it because I was thinking about searching for all information available in a given publication or book - in particular textbooks - in order to use it in a Spaced Repetition Software like Anki. If it would be possible to add as many references as possible, we could ideally represent in Wikidata all the information available in a textbook and export it in a flashcard software if someone need to study that textbook.--Malore (talk) 21:37, 8 April 2018 (UTC)

My perception is that the purpose of references is to help readers and other data consumers to verify that a statement is true, or at least, that the statement correctly reports the position of the referenced source. Creating large numbers of references for a single statement has at least two problems.

1. It is hard for the reader to wade through a long list of references and decide which ones are the best.
2. It is the responsibility of the editor adding a reference to actually read the reference and be sure that it actually supports the statement in Wikidata. This is a lot of work. Any editor adding massive numbers of references to a single statement in rapid succession will be suspected of failing to meet this responsibility. Jc3s5h (talk) 14:34, 9 April 2018 (UTC)

How/where to search through Category:Pages using Wikidata property P#

I found Category:Pages using Wikidata property P566 (Q28039488), now I want to look at all the pages that use P566. WD says it's a Wikimedia category, but it doesn't exist on Wikimedia nor on Wikipedia. — Tom.Reding (talk) 14:46, 9 April 2018 (UTC)

@Tom.Reding: The category represented by the wikidata item is on the ar.wiki here ... quite what or why, I don't know. You can view the items having P566 as a property with the query below; and Property talk:P566 provides some other ways to view items & counts. (The report times out if I try to fetch the values against each P566 ... might try to fix that later.

SELECT ?item ?itemLabel
WHERE {
  ?item wdt:P566 [].
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" . }
}
order by ?itemLabel

Labels and desrciptions

Hello. Vasa Kellakiou (Q7916291) and Vasa Koilaniou (Q7916293). 2 different villages with the same name. People added a second word after their name and we use to use that words even today. But their official name is the same. I was trying to add the official name in English (and Greek) with the same description but the system don't let me. I understand that in same cases when two items have the same label and same description maybe the same item. But in that case they are not. I had to change the description of one of the item. Xaris333 (talk) 23:04, 9 April 2018 (UTC)

It is the case that "no two items may have both the same label and the same description" per Help:Label so amending the description is indeed the way to go. --Tagishsimon (talk) 23:25, 9 April 2018 (UTC)

It seems useless to me. I just add Cyprus to one and Republic of Cyprus to the other. Same thing. I mean that the description its self may not be the way to show the different between them. Xaris333 (talk) 00:08, 10 April 2018 (UTC)

@Xaris333: We routinely use common names instead of official names in labels; "India" instead of "Republic of India", "Hamlet" instead of "The Tragedy of Hamlet, Prince of Denmark", and so on. It makes sense to me to put "Vasa Kellakiou" and "Vasa Koilaniou" as the English labels, each with an alias "Vasa", and within each item leave the official name (P1448) as you have left it. Mahir256 (talk) 00:12, 10 April 2018 (UTC)

It would also be possible to use geographic descriptions, like "village and communal council in the west of Limassol District, Cyprus" vs the one in the east. Ghouston (talk) 00:19, 10 April 2018 (UTC)

It is not useless. It serves to prevent duplicate items being created. The description is expressely "a short phrase designed to disambiguate items with the same or similar labels" (see Help:Description) and thus it is incumbent on us to concoct descriptions that effect that disambiguation - as Ghouston's example does. It's deliberately not okay to to seek a same label same description, and force the user to rely on other claims to disambuguate, since only the label and description are supplied in search results and so discovery of items by search is frustrated. --Tagishsimon (talk) 01:22, 10 April 2018 (UTC)

human (Q5) violates subclass constraint

On human (Q5), the "subclass of: person" statement has an issue attached that I found rather confusing. It says "conflicts-with constraint: An entity should not have a statement for subclass of if it also has a statement for instance of (P31) with value common name (Q502895)." --Krinkle (talk) 02:26, 10 April 2018 (UTC)

I read this as saying, inter alia, that because "human" is a common name, it is the thing that it is a common name of (i.e. homo sapiens) that should have the subclass of person claim, and not the common name item. --Tagishsimon (talk) 04:38, 10 April 2018 (UTC)

Such issues have been discussed previously on Talk:Q5 and elsewhere, but it's hard to convince anybody to change the status quo. Ghouston (talk) 05:10, 10 April 2018 (UTC)

anonymous (Q4233718) violates gender constraint

At anonymous (Q4233718), the "sex or gender: unknown value" statements shows the following issue: "conflicts-with constraint: An entity should not have statements for both sex or gender (P21) and subclass of (P279)}}." Can someone explain why that constraint exists? And how should we solve it? --Krinkle (talk) 02:25, 10 April 2018 (UTC)

Because sex or gender applies to an individual thing, which will be an instance of something, not a subclass of something. How to fix? anonymous (Q4233718) is quite sucky right now. The en description somewhat nails it: the item is a term (Q1969448) which represents an unsupplied creator name. The item is not a human, nor is it a subclass of a humen, creator, etc etc. It is a term. The item should not, therefore, have lots of 'unknown values' for a series of attributes of humans. It should instead have claims that are suited to the description of the term, such as

⟨ anonymous (Q4233718)    ⟩ subclass of (P279) ⟨ pseudonym (Q61002)    ⟩

. --Tagishsimon (talk) 04:04, 10 April 2018 (UTC)

If that was changed it would probably introduce other constraint violations when it's used for an author etc., like "author should have a gender". Ghouston (talk) 05:15, 10 April 2018 (UTC)

Agreed. Though a quick look at items with a P50 of Q4233718 suggests that many should have P50='unknown value' and a very few should have a pseudonym (P742) of Q4233718. --Tagishsimon (talk) 05:4710 April 2018 (UTC)

This is a particularly egregious error, because it is quite possible that the creator of a specific work is both anonymous and known to be male, or known to be female. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 08:28, 10 April 2018 (UTC)

Translate

• Near statements a magnifying glass is showing. The word more is showing when the cursor is on it. I want to translate that but I can't find it in translatewiki.net.

• I also want to translate Query Service, Concept URI, Mark as duplicate, VIP's labels, Browse Primary Sources, ▲ back to top ▲, Random Primary Sources item, Primary Sources list, Check sitelink from the left column of Wikidata. (Maybe some are from gadgets).

More than 50% of my edits get reverted. And "Days of The Week" are separated into 2 items; undiscussed.

1. Everything starts with one day I find that the Chinese, English, Deutsch version of the "Days of the Week" are not connected. 42 languages are in one group and 11 languages are in the other group, and I found no discussion about the split in Wikidata or the English Wiki, so I merged them. And then I got reverted by User:Andreasmperu. So I merged them with a message "No one single language separates this exact same topic. No separation discussion found in wikidata or english wiki of the topic 'Days of the week'", and leave a comment on the Talk:Q41825 "Separation will create unnecessary difficulties to compare difficult languages of the 'Days in the Week'.". And then I got reverted by the same admin again with just two words "wrong item" with no reply on the discussion page. [9] [10]
2. As a result, more than 50% of my edits in Wikidata get reverted without a reason. If you do Google translate, you will know these two are the same topic "a ship destroyed and sank".
3. G translate will tell you that these two(w:en:Chuanyue) are about the same topic of "Time Travel Fiction".
4. Click in to look at the map and coordination and you know one is about the same town, and the other is not a town.
5. You don't even need Google translate to know these two are the exact same group of Baptist Universities. Just spend 5 seconds to click in.

What an irony that an IP user is more willing to explain and communicate than an administrator. 118.143.147.130 22:01, 9 April 2018 (UTC)

In the first case, you seem to have conflated "Names of the days of the week" with "Day of the week". That's an error, since those are different concepts, and was rightly reverted. Similarly, not all time travel in fiction is a time travel novel. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:24, 9 April 2018 (UTC)

Per Andy, you in fact get 5/5 wrong.

1. Two different concepts, names of days of the week versus day of the week.
2. Disambiguation page versus article
3. As noted, not all time travel in fiction is a time travel novel; different concepts.
4. zh.wiki has articles attached to both items. You'd need to sort that out before they could be merged.
5. Disambiguation page versus list article. You can argue that zh.wiki should change their article to a list, but until they do, it's a dab, and we need to reflect that.

So. Sorry about that. --Tagishsimon (talk) 22:54, 9 April 2018 (UTC)

1. The English Wiki "Names of the days of the week" is actually the same article moved from "Days of the week". What topic of contents is different before the en-wiki article moved from "Days of the Week" and after moved to the current "w:Names of the days of the week"? They are still all about the exact same topic: how to count the seven days, their astronomy origins and their names in different languages. "No one single language Wiki separates this exact same topic into two articles" is the strongest evidence that none of the 53 languages thinks that they are about different topics.
2. I don't think good idea to separate the exact same topic of different languages simply because one has less content. This will break the cross-reference and cross-improvement connections among different languages.
3. Of course, fiction includes novels and films. It is wrong to say that "小說" in Chinese only includes written books. 小說 does include films and other forms of art, so 穿越小說 is same as "Time travel in fiction" and both of them include "Time travel novel". Google translate tells you the same 小說=Fiction Fiction=小說.
4. I wonder whether you guys did click in for 5 seconds. w:zh:金字牌鎮 and w:sv:Jinzipai (köpinghuvudort i Kina, Anhui Sheng, lat 29,85, long 117,81) are the same location at (29.85 N, 117.81 E). w:zh:金字牌 is a "message certificate of royal orders", which is definitely not a location.
5. Bad idea to separate the exact same topic of different languages; not to mention even their content are the same. So if I change the w:Baptist University to disambiguation, this one is done? 118.143.147.130 12:24, 10 April 2018 (UTC)

1. (All IMO...) This one is something of a clusterfuck. The two wikidata items are distinct and for that reason should not be merged. However I concede that there are claims and wikilinks on day of the week (Q41825) that belong instead on names of the days of the week (Q42962347) or on another item (e.g. the GND ID seems to point to a concept of 'Working Days'). I concede, too, that not much may be left on day of the week (Q41825) by the time we finish.
2. These remain two distinct items, one pointing to articles on concept of shipwreck/ing, the other a zh disambiguation page. zh's article on shipwrecks was pointed at the wikidata item maritime disaster (Q2620513) ... I've moved it to shipwrecking (Q906512). I think that's now sorted?
3. So for this one ... chuanyue (Q10453828) is a distinct subclass of time travel in fiction (Q253732) and the two should not be merged. The zh. wikilink from chuanyue (Q10453828) looks appropriate; is about tt novels. The en. wikilink was to an article on Chuanyue which is a distinct subclass of chuanyue (Q10453828) ... I've created a new item, chuanyue (Q51733250) and moved the en. wikilink to it. I'm hoping we're good on this now.
4. This one should be sorted now.
5. Yes; I've done that. With luck, also sorted.

More generally, you'll not get much dispute that there is a lot wrong or that can be improved in many wikidata items. Exactly how to effect improvement can be a more thorny issue. --Tagishsimon (talk) 00:47, 11 April 2018 (UTC)

Linking templates to categories and lists without a main topic item

I'm wondering how to link an item for a list-like navigational template to the corresponding list and category items, when there is no corresponding main topic item. A specific example is Template:Major National Historical and Cultural Sites (Jiangsu) (Q20691005), which corresponds to the list Major National Historical and Cultural Sites (Jiangsu) (Q1188621) and category Category:Major National Historical and Cultural Sites in Jiangsu (Q17392112). The category and list can be linked to each other without using a main topic, using category related to list (P1754) and list related to category (P1753). Are there similar properties for templates, and should there be? Rigadoun (talk) 14:32, 10 April 2018 (UTC)

This seems like a good use case for a ‘template combines topics’ property (by analogy with category combines topics (P971)). Mahir256 (talk) 14:43, 10 April 2018 (UTC)

Agree. --Edgars2007 (talk) 10:33, 11 April 2018 (UTC)

template has topic (P1423) and topic's main template (P1424) are what you're looking for, with the list as the main topic. Thanks. Mike Peel (talk) 14:32, 11 April 2018 (UTC)

Organizations with more than one official website

official website (P856) says there can only be one per item but some organizations have two (or more) official domains. For example, canoe.ca (Q902502) (Canadian Online Explorer) has two portals: canoe.ca (French) and canoe.com (English). Caras (Q9696470) has three portals: caras.perfil.com (Spanish), caras.uol.br (Portuguese of Brazil) and caras.sapo.pt (Portuguese of Portugal). --Metrónomo (talk) 08:25, 11 April 2018 (UTC)

Note: be careful when reading Caras (Q9696470) because I am still developing it, I need to investigate a little more. The information presented in the Wikipedia in English and Portuguese is partially true and incomplete. Here (page 38) say that Caras was founded by Grupo Perfil in Buenos Aires in 1992 and it started as a spanish magazine. Then it began to be published in Brazil (1993), Portugal (1995), Angola (2004) and Uruguay (2007). In 1993, Grupo Perfil was associated with Grupo Abril and in 1995 it was associated with Grupo Impresa. In 2014, Grupo Perfil bought the part from Grupo Abril and today is the only owner of the franchise (Argentina, Brasil, Angola and Uruguay) except for Caras Portugal who continues to share with Grupo Impresa. I'm not quite sure how to reflect that on Wikidata (co-owners or local partners). --Metrónomo (talk) 08:46, 11 April 2018 (UTC)

Pick the main one like how it's done on Google Search (Q9366) otherwise you'll end up with long lists. Multichill (talk) 09:56, 11 April 2018 (UTC)

In the case of Canoë, none is the main one (French/English duality in Canada). In the case of Caras can be considered (Spanish?) Even if you choose the one you choose, someone will always disagree (Portuguese speakers will say: why Spanish?) The difference with Google is that we all agree which is the main or most representative site. --Metrónomo (talk) 10:38, 11 April 2018 (UTC)

A discussion from 2016 at Property_talk:P856 suggests allowing multiple values if they are qualified somehow, like language of work or name (P407), applies to jurisdiction (P1001) or intended public (P2360). I'm not sure if doing that fixes the constraint. Ghouston (talk) 11:41, 11 April 2018 (UTC)

The constraint statement already has separator (P4155) parameters, which should allow multiple values as long as they have different qualifiers for e. g. language of work or name (P407) – but unfortunately we haven’t implemented support for that parameter in the WikibaseQualityConstraints extension yet, see phabricator:T173594. --Lucas Werkmeister (WMDE) (talk) 13:18, 11 April 2018 (UTC)

Formatter URLs for GET request method

Data from an ORCID record can be fetched using the relevant ORCID iD (P496) value and HTTP GET (Q30542074), thus:

https://pub.orcid.org/v2.0/0000-0001-5882-6823/person

I have stored that here using formatter URI for RDF resource (P1921) - is there a better way to record this? As formatter URL (P1630)? Do we need a new property, "GET formatter URL"? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:15, 11 April 2018 (UTC)

@Pigsonthewing: I don’t think that’s correct – an URL with a v2.0 version number in it doesn’t look very much like a canonical URI to me.

And I don’t think there’s any need to store this URL separately, in fact – if you request the real canonical URI, e. g. https://orcid.org/0000-0001-5882-6823, with the right Accept header (e. g. Accept: application/xml), it redirects you to the pub.orcid.org/v2.0/… URL. We do the same thing in Wikidata – see WD:Data access#Linked Data interface. --Lucas Werkmeister (talk) 15:30, 11 April 2018 (UTC)

┌────────────────────────────────────────────────────────────────────────────────────────────────────┘

It is true that:

https://pub.orcid.org/0000-0001-5882-6823/person

will also work. However my question is how we can best store such URLs for cases where your solution either does not work, or or is not available to the user. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:55, 11 April 2018 (UTC)

Improvements on the search results

Hello all,

Some improvements have been made by the Search team at WMF on Special:Search (the page that is loaded when you type something in the search field and press enter, for example).

• The string that you typed is highlighted in bold in the label of the results
• The number of bytes is no longer displayed, instead you can see the number of sitelinks and statements
• The code is now using the same indexing as completion search, which should improve relevancy and better control over ranking

If you have any question or find a bug, feel free to ping user:Smalyshev (WMF). Lea Lacroix (WMDE) (talk) 07:33, 5 April 2018 (UTC)

Good improvement. Thanks! Paucabot (talk) 08:10, 5 April 2018 (UTC)

@Smalyshev (WMF): The first one. Somehow I thought it was about all items, but apparently it's just for those with Q4167410 (and Q13442814 added later).
--- Jura 07:18, 6 April 2018 (UTC)

Great! Hmm, when I search "US" (capitalization doesn't matter, probably), in completion search I see United States of America (Q30) (which is expected), but in Special:Search the country is outside of first page. --Edgars2007 (talk) 07:24, 6 April 2018 (UTC)

For me, searching for "US" ranks United States of America (Q30) first in both contexts. But for "USA", United States of America (Q30) only comes out second in Special:Search. I would be interested in understanding the difference between the two endpoints. − Pintoch (talk) 08:56, 8 April 2018 (UTC)

@Smalyshev (WMF): is there a way to get the Special:Search results via the API? It seems to me that the "srsearch" action still uses the old index (example: https://www.wikidata.org/w/api.php?action=query&list=search&srsearch=united+states&srnamespace=0 ranks United States of America (Q30) in 7th position instead of 1st for Special:Search). − Pintoch (talk) 19:30, 12 April 2018 (UTC)

This is strange, the code should use the same code path. I'll check that. Smalyshev (WMF) (talk) 19:33, 12 April 2018 (UTC)

Revamping the list of properties

The list of properties is out of date. Not only that, some subpages like this one show errors. I was wondering if someone has the technical skills to write a bot that could automate the list based on the classification of the property tree which is always updated. Said bot could either write listeria queries for each branch or use {{List of properties/Row}}. What do you think? What would be the best way to do it? Micru (talk) 18:12, 3 April 2018 (UTC)

Wouldn't a category, or category tree, be better? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:30, 4 April 2018 (UTC)

@Pigsonthewing: How would you categorize the properties? AFAIK there is no way to add the properties to any category, unless you put it on the talk page, which is less than ideal... Micru (talk) 20:06, 4 April 2018 (UTC)

Yes, I was thinking of the talk pages. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:53, 5 April 2018 (UTC)

Feedback requested on educational resources and curricula

I have a goal of creating a series of lessons which a new user could follow to gain the skills to use Wikidata.

I drafted an outline of resources.

• Wikidata:Wikidata educational resources
• Wikidata:Wikidata curricula

My thought is that I will seek to collect any lessons on the "educational resources" page, then include those individual lessons and more into a curriculum on the "curricula" page.

Here is the feedback I am seeking now:

1. Can anyone inform me if they are aware of any Wikidata page which already serves either of these functions? Is there a catch-all directory of educational resources, and has anyone already outlined how to create a Wikidata class learning plan?
2. Can anyone post more educational resources to that page?
3. Can anyone direct me to individuals who are likely to want to collaborate in developing a multi-part lesson plan for new users to learn Wikidata?

Thanks. Blue Rasberry (talk) 19:49, 11 April 2018 (UTC)

@Titodutta: Thanks. This is not stable. I am seeking comments from others. If you are aware of anything equivalent in other languages then share. I have no idea what already exists.

How to load a new dataset?

Hello, I'm wondering what is the correct process for loading a dataset. Some week ago, I tried to open up a new purpose here, but now I do not know how to proceed. Floatingpurr (talk) 09:47, 12 April 2018 (UTC)

Seems to be plenty of supply on that page, but hardly any demand. Multichill (talk) 19:28, 12 April 2018 (UTC)

I see. So what how can I do if I want to contribute loading datasets? Floatingpurr (talk) 11:24, 13 April 2018 (UTC)

There are probably three or four main tasks associated with this proposed upload: 1. Working out whether we already have records for any of the schools 2. working out the coding so we can represent e.g. Region or Province to our values for Italian regions & Provinces 3. Actually uploading the data, probably using QuickStatements 2 (Q29032512) and possibly 4. creating a new property for CODICESCUOLA (and, who knows, thinking about CODICEISTITUTORIFERIMENTO and whether we need to support that ID). So it's a non-trivial task, I'm afraid, one which will take a considerable amount of effort to achieve. There is not an automagical solution. So the question is, whether you have the time and aptitude to do the work? I can probably give you pointers. --Tagishsimon (talk) 14:28, 13 April 2018 (UTC)

Thanks for your kind reply. So, I'd like to contribute and to try loading datasets for becoming confident with this process. I go over your points. 1. There are definitely record of such schools, for example this one Liceo Classico Massimo D'Azeglio (Q3268994). I guess the only way to get them all is string matching, right? How do I merge existing data? 2. Again, also in this case string matching is the only way, isn't it? 3. Aren't there APIs for loading data (e.g., the ones the bots harness)? Do I need a bot to load them? 4. I may start loading just basic info. I understand it's not a trivial task and I do not know how much time I can dedicate to this task. Anyway, I still do not find a clear way for contributing with huge data loadings, like this one. Floatingpurr (talk) 23:52, 13 April 2018 (UTC)

Property "Time of the day" by using 1440 items

Since the use case of "time of the day" is different than the use case of "duration in HH:MM:SS", I was wondering if we could create a property "time of the day" with data type item which takes as value one of 1440 items (24h * 60min), each one labeled as "00:00", "00:01", "00:02", and so on. Would it make sense? Are there any use cases?

For opening hours I suppose we would need a property "open on" with item values "Monday", "Tuesday", etc. and qualifiers "start time of the day" and "end time of the day".

Thoughts? --Micru (talk) 21:14, 13 April 2018 (UTC)

I'm also thinking that perhaps there is no need to create so many items, as normally the only items used would be for hours, or half-hours, perhaps quarters in some rare occasions. In that case only 96 items (4*24) would be necessary to have the most used times 0h, 0:15, 0:30, 0:45, and so on. --Micru (talk) 10:36, 15 April 2018 (UTC)

Records and record progressions

On the one hand, the English-language Wikipedia has an article called Flight airspeed record, on the other hand, it has an article called Men's pole vault world record progression.

Now two examples are given for record held (P1000), Renaud Lavillenie (Q1742) → men's pole vault world record (Q1136293) and Augustus Orlebar (Q4821509) → flight airspeed record (Q1038621), but one cannot say that Lavillenie holds the men's pole vault world record progression. What to do about this, changing the Wikidata label into men's pole vault world record but leaving the Wikipedia article linked to it? Note that the French label is record du monde du saut à la perche (OK) and the German label is Stabhochsprungweltrekorde der Männer (plural!).

I am also uncontent with the use of the property record held (P1000) in the item 100 metres (Q164761). It is not like Usain Bolt is a record held by the 100 metres race; rather, the record for the fastest 100 metres race is held by Usain Bolt. -- IvanP (talk) 15:12, 14 April 2018 (UTC)

men's pole vault world record (Q1136293) actually seems like the better target, because it's an item for a subclass of world records, unlike flight airspeed record (Q1038621) which is an item for a Wikimedia list article. I think it would be OK to change the label. record held (P1000) in 100 metres (Q164761) is just backwards. Ghouston (talk) 03:56, 15 April 2018 (UTC)

Translating "Motivation"

Currently, property proposals have the string "Discussion" translated, by inputting {{int:Talk}} which outputs "Discussion". It would be useful to have the header "Motivation" also internationalized. The preloaded property proposal template would also need to be updated. NMaia (talk) 13:18, 15 April 2018 (UTC)

instance of:list and P279

Somehow subclass of (P279) doesn't work well on items for lists. That is items with instance of (P31)=Wikimedia list article (Q13406463).

There are some on Wikidata:WikiProject Lists/reports/P279 cleanup. It includes:

• 1. Items with labels = "list of" and a subclass that is also labeled "list of"
• 2. Items with labels = "list of" and a subclass that is not labeled "list of"
• 3. Items with labels in plural (other than "list of") and a subclass that is not labeled "list of"
• 4. Items with labels in singular (other than "list of") and a subclass that is not labeled "list of"

What to do?

• For (4), the solution would probably be to remove p31=Wikimedia list article (Q13406463).
• Maybe for (3) as well.
• For 1 and 2, the value of P279 should probably be moved to another property.

⟨ London (Q84)    ⟩ official name (P1448) ⟨ London ⟩
follows (P155) ⟨ Roman London (Q927198)    ⟩

or more colloquially

⟨ London (Q84)    ⟩ name (P2561) ⟨ London ⟩
follows (P155) ⟨ Roman London (Q927198)    ⟩

 ? --Tagishsimon (talk) 06:52, 10 April 2018 (UTC)

Or kill the constraint. I suspect it's used "incorrectly" (i.e. not as a qualifier) at leastr as often as it used "correctly" according to the constraint. - PKM (talk) 20:14, 12 April 2018 (UTC)

┌────────────────────────────────────────────────────────────────────────────────────────────────────┘ From the SQUID poperty browser:

• followed by (P156) used as Statement: 381,522 Qualifier: 77,925
• follows (P155) used as Statement: 391,115 Qualifier: 78,487

This constraint is a lost cause. - PKM (talk) 21:36, 13 April 2018 (UTC)

• Sigh. But this constraint is not accidental - using these properties as main properties makes semantics more ambiguous: one cannot tell in which sequence they are "next/previous". The other solution was always to mark sequence as a qualifier with P361 or better part of the series (P179). But this approach seems to be even more rare. --Infovarius (talk) 09:29, 15 April 2018 (UTC)

So how could we fix these ~300k "errors"? It seems we'd need to convene a task force or some such, to make or find a sequence/series that is appropriate and then edit them all. - PKM (talk) 19:35, 15 April 2018 (UTC)

Refound date

We are using inception (P571) and dissolved, abolished or demolished date (P576) for a team foundation date and dissolved date. But, what we do if a team refounded after dissolved? Two different questions I have.

1) We put the refounded date at P571, as a second value? But, it has the constraint single-value constraint (Q19474404). How can we show that the team was refounded a specific date?

2) We made P576 value a deprecated rank? (sorry for my English)

3) If the team dissolved again? P756 has the constraint single-value constraint (Q19474404).

My example,

Pezoporikos Larnaca FC (Q2277220) founded at 1924, then dissolved at 1932 (merged with other team, created a new team), then refounded at 1937 and then dissolved at 1994 (merged with other team). For other teams, they just dissolved (not by merging) and refounded some years later.

Xaris333 (talk) 22:37, 14 April 2018 (UTC)

I'd say first decide whether the refounding is genuinely the same team, and not a new team with the same name. The same thing also happens with other types of organization like political parties and companies. If it a continuation, then I suppose you'd use inception (P571) for the first founding date, and dissolved, abolished or demolished date (P576) for the final dissolved date, with periods of inactivity not recorded in that way. Ghouston (talk) 23:14, 14 April 2018 (UTC)

Its the same team... Ok, but with your way we lose informations. There is a time in period that the team, political party, company, didn't exist. Xaris333 (talk) 23:51, 14 April 2018 (UTC)

Because that first time it dissolved it wasn't a true dissolution, because it continued at a later period. And the refounding isn't a true foundation since it existed previously. Ghouston (talk) 03:32, 15 April 2018 (UTC)

But how can we show that the team, political party, company didn't exist for some years? That period, the dissolution was true. Xaris333 (talk) 04:18, 15 April 2018 (UTC)

Maybe with significant event (P793) with date of dissolution, abolition or demolition (Q29933798) and point in time (Q186408), although this seems confusing. There don't seem to be items for start and end of a period of inactivity, or temporary cessation / restart. Ghouston (talk) 07:16, 15 April 2018 (UTC)

Quite a few such examples can be found by searching for "refounding" in Wikipedia. A lot of them seem to be sports teams, but Saxony-Anhalt (Q1206) is also a good example. Perhaps defining a couple of new items to be used with significant event (P793) would handle it? Ghouston (talk) 07:30, 15 April 2018 (UTC)

Identity is strongly associated to the temporal continuity of existence, which is delimited by a start date and an end date. If something ceases to exist, that will never exist again nor will be recreated, and a future entity with the same name should be considered a different entity. So I would create several entities in Wikidata, since I also consider them different entities in the real world. --abián 13:25, 15 April 2018 (UTC)

Wikidata doesn't really have the privilege of deciding such things: it's determined by whether the entity has multiple Wikipedia entries or a single entry. Perhaps a case will turn up that has multiple entries in one language and a singe entry in another. In reality its messy: there are likely to be aspects in which the entity acts as a continuation (beyond just the name, such as having some of the same people involved) and aspects in which it acts as a new entity (such as a new legal registration.) Did China become a new state in 1949 when it became the People's Republic of China (Q148), or is was it a continuation of the same state with a new government and new name? We have People's Republic of China (Q148) founded in 1949. Ghouston (talk) 23:39, 15 April 2018 (UTC)

Title

Hello. Why title (P1476) should only contain a single value? Some papers and files have two languages on them. For example English and Greek. No one of the language can be called as the original and the other as the translated language. Both are the original languages. Xaris333 (talk) 19:02, 4 April 2018 (UTC)

You can enter both titles, and then edit title (P1476) to have a new "exception to constraint" for this particular item that has two titles. - PKM (talk) 20:39, 4 April 2018 (UTC)

But there are many items. Xaris333 (talk) 22:17, 4 April 2018 (UTC)

@Xaris333: Can you give an example or two, please? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:51, 5 April 2018 (UTC)

@Pigsonthewing: See Amiantos (Q6377735) --> population (P1082) --> 262. See the source. Xaris333 (talk) 13:33, 5 April 2018 (UTC)

Thank you. I was looking for examples of Wikidata items about such works. Incidentally, you can link to a specific property on an item, like this: Q6377735#P1082. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:06, 5 April 2018 (UTC)

there are also all multilingual editions of books or texts in wikisource, with a link on both ws projects, like Q25991162, which is a whole book, or Q25991163, which is a poem. As all poems and individual works in those multilingual texts are to be referenced, there will be a LOT of them, just for latin authors :)

aaannd cases of poems that are known and published under various titles (in the same edition), like medieval Rutebeuf's see here Q19181898, where 3 different titles are mentioned on the very same page of the same edition :/ --Hsarrazin (talk) 15:21, 5 April 2018 (UTC)

Should we remove the constraint? Xaris333 (talk) 01:20, 6 April 2018 (UTC)

•  Support removing the single-value constraint on "title". - PKM (talk) 19:42, 9 April 2018 (UTC)
•  Oppose The overwhelming majority of the cases will still have only a single value, and all too often extra values are added that shouldn't be there. It's not a mandatory constraint, but the constraint is useful for tracking these cases. – Máté (talk) 06:19, 11 April 2018 (UTC)

Change a birth date on a protected page

I am not autoconfirmed since I don't edit wikidata. The issue is with María Félix (Q465189). She was born 4 May not 8 April (that's her death date). Google recently made a doodle of the actress mistakenly giving that date as her birthday. Here is a source for her actual birth from the New York Times obituary: "Ms. Félix was born María de los Ángeles Félix Guereña, on May 4, 1914, in Álamos, Sonora, according to the birth certificate discovered by Paco Ignacio Taibo, the author of La Doña, a 1985 biography of Ms. Félix."

Updating Wikidata:List of properties

Since all of our old lists of properties are outdated, I would like to replace Wikidata:List of properties with a new User:Micru/Wikidata:List of properties.

Could you please take a look and voice your opinion? Thanks! --Micru (talk) 20:00, 13 April 2018 (UTC)

• Hi, I would agree that we need better ways to explore and visualize properties, and your proposal goes into the right direction. However, some of the tools you are listing are by far not mature (yet). For example, it should definitely be possible to filter out all the identifier properties - in fact they should be explorable separately from the other properties. Also, some of the standard queries of the tools you are referencing run into time-out issues (at least when run from the Mozilla Browser, which has a lower performance on the SPARQL service than for example Google Chrome). Cheers. --Beat Estermann (talk) 09:48, 15 April 2018 (UTC)

@Beat Estermann: Prop explorer has been updated and now you can filter out all the identifier properties, and you can explore them independently if you wish, just select the type of property that you want to show. If you tell me which tools give you problems I can either contact the tool creators or add a notice with the potential issues. So do you think the proposed page is now ready to be used as default? --Micru (talk) 07:35, 16 April 2018 (UTC)

New constraint to enforce that two properties have the same value on a given item

There is an ongoing discussion at Wikidata:Property proposal/Directory of Open Access Journals ID and Wikidata:Property proposal/Plants of the World online (among others) about how to link to two different databases which use the same identifier. The simplest solution seems to consist in creating two distinct properties which would generally have the same value when they are present on the same item (but different URLs generated by the formatters). It can be a burden to deal with this redundancy so some editors wonder if a new type of constraint could be created to alleviate that. Would that be an appropriate solution? @Lucas Werkmeister (WMDE): would it be technically feasible? − Pintoch (talk) 08:51, 8 April 2018 (UTC)

┌────────────────────────────────────────────────────────────────────────────────────────────────────┘ As I've noted elsewhere, "distinct properties which would generally have the same value" is far from simple, and is in fact a harmful way to proceed. Consider:

for which we currently have Flora of North America taxon ID (P1727) and Flora of China ID (P1747); with a further eighteen potential properties to follow. Sadly, only four people responded when I raised this here and at Wikidata:Requests for deletions/Archive/2018/Properties/1#eFlora properties. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:52, 8 April 2018 (UTC)

This seems to be a slightly different issue as all these URLs come from the same database. I understand that you vocally oppose the creation of these properties but I still don't understand what you are proposing to do instead (specifically for the two proposals linked above)? Third-party formatter URLs are not a solution for this particular problem. − Pintoch (talk) 12:14, 8 April 2018 (UTC)

"Third-party formatter URLs are not a solution for this particular problem" Yes, they are; and that is the solution I have - quite clearly - proposed. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:34, 8 April 2018 (UTC)

@Pintoch: I tend to agree with Andy here: we should be using a third-party formatter URL in these cases. Unless there is at least one instance where the identifier differs between, say, P1727 and P1747 for the same item (which judging from Andy's links is in the same database), the two properties should be unified. What should be worked on is a way to control which formatter URL appears on a given item—in this case, based on some sort of geographical information on the item itself. Mahir256 (talk) 18:46, 8 April 2018 (UTC)

@Pigsonthewing, Mahir256: Sorry if it is obvious but I still do not see how you would use a third-party formatter URL to indicate that a given identifier is available in database X but not in database Y? For instance, not all ISSNs can be found in DOAJ. Also I don't see in which context the third-party formatter URL is actually used to generate a link for the identifier in the Wikibase UI? It would be great if you could give a very concrete example of this, because I think that I am not the only one who does not get it. − Pintoch (talk) 19:13, 8 April 2018 (UTC)

Couldn't we create a property for journals like IndexedIn:DOAJ ? --Gerwoman (talk) 19:17, 8 April 2018 (UTC)

To piggyback off Gerwoman's suggestion, why not have the formatter URL change based on a reference "stated in (P248) Flora of China (Q5460442)" or "stated in (P248) Directory of Open Access Journals (Q1227538)" as appropriate? Mahir256 (talk) 19:22, 8 April 2018 (UTC)

That's intuitively harder to implement, but why not. As far as I understand Andy claims that somehow no change is needed and third party formatters already provide a solution. − Pintoch (talk) 21:36, 8 April 2018 (UTC)

While it is not necessary to "indicate that a given identifier is available in database X but not in database Y" (that's what the 404 response code is for), it is possible to do so, using referencing, as I have demonstrated previously. You were apparently aware of the example I gave then. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:36, 9 April 2018 (UTC)

As I understand it, people just want to have a hypertext link to the said databases. Manually constructing the link from a third-party formatter URL and checking if it resolves correctly might be an option for bots, but not for people. So even if I like the idea, I don't really see how this method is a solution: that involves statically instantiating the third-party formatter URL for the given ID (which makes it hard to update the URLs if the format of the website changes). And I guess it is not very convenient for users either, as they have to expand references to check if there is a link there. I am not really speaking for myself here: I just notice that there are quite a lot of support votes for these properties, and I am worried that by refusing their creation we are going to make their life harder. − Pintoch (talk) 14:22, 9 April 2018 (UTC)

Hello all,

Feel free to create a ticket on Phabricator, with the tags Wikidata and Wikibase-Quality-Constraints. Don't forget to provide examples of what you need. Is this related to this specific property, or would you need it for others as well? We'll have a look as soon as possible.

Thanks! I have created a task here: https://phabricator.wikimedia.org/T191963 − Pintoch (talk) 09:49, 11 April 2018 (UTC)

"people just want to have a hypertext link to the said databases" Perhaps. But given Wikidata's purpose, is that the right thing for us to do? "I want" is not a very compelling use-case. "that involves statically instantiating the third-party formatter URL for the given ID ". No, it involves giving a valid citation for the data; and happily also meets your requirement to "indicate that a given identifier is available in database X but not in database Y".

IAFD person Ambiguity properties

There is an ambiguity with the IAFD person properties on Wikidata, IAFD male performer ID (P4505) and IAFD female performer ID (P3869), the correct one would be to only exist an "IAFD person ID" as like Adult Film Database person ID (P3351) . I believe that this ambiguity occurred because of the second parameter gender. It was mistaken for a secondary ID, in fact it is just a layout parameter for the IAFD site.

All links below point to the same element on the IAFD site.

This ambiguity makes it difficult to integrate with templates on Wikipedia.

Note: IAFD is an "adult film" database and the above links may be considered "not safe for work". Having learned that the, er, difficult, way: your first two links return different data. For example, the first link has no picture, while the second does; and the former only lists two films; the latter has 342. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:12, 10 April 2018 (UTC)

Yes @Pigsonthewing:. But that does not justify treating people of masculine, feminine, and "director" genres as different elements. If you repair the first link, without this parameter already have the correct information.Guilherme Burn (talk) 15:32, 10 April 2018 (UTC)

Is it possible to rename a property? If yes, it would be enough to exclude the less used one and renomer another. Of course, if there is consensus.Guilherme Burn (talk) 19:33, 16 April 2018 (UTC)

Dye plants

Do people prefer Reseda luteola (Q157927) <instance of> dye plant (Q907341) or Reseda luteola (Q157927) <use> dye plant (Q907341)? I prefer <instance of> but not enough to argue about it if others disagree, as long as we're consistent. There are only two instances so far, so I can change them easily if that's the consensus. - PKM (talk) 22:56, 16 April 2018 (UTC)

Or perhaps <subclass of> dye plant (Q907341)? - PKM (talk) 23:07, 16 April 2018 (UTC)

Instance or subclass. dye plant (Q907341) has a description "plant from which a dye can be extracted" and a has use (P366) with the value dyeing (Q1164991). I could do with more guidance on instance versus subclass; it's not always clear to me which is appropriate. --Tagishsimon (talk) 23:11, 16 April 2018 (UTC)

An individual plant would be an instance, Reseda luteola (Q157927) is a class of many plants. Ghouston (talk) 01:12, 17 April 2018 (UTC)

I think generally it's not a good idea to go overboard with subclassing. It's nice that all humans are instances of the same item (even if that item is somewhat screwed up.) I think I'd just make each species a subclass of its parent taxon and identify its characteristics with other properties. Ghouston (talk) 01:20, 17 April 2018 (UTC)

defining formula (P2534)

Is $\left(M,*,e\right)$ really a defining formula for monoid (Q208237)? ${\boldsymbol {S}}=(S,*)$ (from semigroup (Q207348)) is at least an equation, but $(S,*)$ is not a notation specifically for a semigroup, rather, it can be used to define what a semigroup is by saying that $(S,*)$ is a semigroup iff $*$ is an associative operation and $S$ is a set closed under $*$.

Furthermore, has characteristic (P1552) currently has two values in monoid (Q208237), identity element (Q185813) and associativity (Q177251). I am fine with identity element (Q185813) – there are monoids with different identity elements –, but think that associativity (Q177251) is inappropriate. -- IvanP (talk) 18:57, 16 April 2018 (UTC)

@IvanP: On defining formula, a lot of these were imported wholesale from enwiki in a careless manner, and I've deleted hundreds that were just inappropriate. However the two you mention were added more recently by @Bigbossfarin: - might be something else going on here? ArthurPSmith (talk) 12:37, 17 April 2018 (UTC)

Hi, I was importing the formula from de-wiki. In this sense a monoid (Q208237) is defined as a triple (Q20088882) $\left(M,*,e\right)$, where $M$ is a set (Q36161), $*$ is a associative internal binary operation (Q47407371) on $M$ and $e$ a identity element (Q185813) in $*$. The input box is simply to short to get all this information in it. Maybe ${\boldsymbol {M}}=\left(M,*,e\right)$ would be an improvement? And I agree with you that associativity (Q177251) is very inaccurate. --Bigbossfarin (talk) 13:30, 17 April 2018 (UTC)

Dear administrators,

Mr Javier Gomá (https://www.wikidata.org/wiki/Q6165536) was hired by the Juan March Foundation in 1996. In 2003, he was named executive director. How can I express it in Wikidata? I am not able to put 2 years.

Translation not updated

Tracked in Phabricator
Task T192379
Resolved

Can someone tell me why this translation has not been yet replicated to MediaWiki:Valueview-expertextender-languageselector-label/ca? I translated it last december. Thanks, Paucabot (talk) 14:47, 17 April 2018 (UTC)

@Paucabot: the translation was imported correctly (Gerrit change Idd2f67762d), but that message is not directly part of Wikibase (the MediaWiki extension that powers Wikidata), but of a library which Wikibase uses. Wikibase imports the latest released version of that library, and we haven’t released a new version of it since November, so all translation changes since then aren’t effective on Wikidata yet. We’ll try to get this fixed, it should be deployed either tomorrow or next Wednesday. Thanks for translating, and for bringing this to our attention! --Lucas Werkmeister (WMDE) (talk) 16:17, 17 April 2018 (UTC)

Commons Cultural heritage monuments with known IDs

Hi guys,

The question is simple, there's some effort to make this: Category:Cultural heritage monuments with known IDs some how useful here, there's some integration possible to both worlds? Rodrigo Tetsuo Argenton (talk) 20:04, 15 April 2018 (UTC)

@Rodrigo Tetsuo Argenton: Sorry, I don't understand your question. Can you please rephrase it? You're probably interested in Wikidata:WikiProject WLM. Multichill (talk) 21:17, 15 April 2018 (UTC)

@Multichill:, if there is any kind of integration between the categories/templates at Wikimedia Commons and here. We have there a number to identify the monument, maybe we could use some how here. Because, we have there thousands of images identified, and as we categorised it by template, we could simply change the templates and created a bridge there easily by bot, not manually as now.

Rodrigo Tetsuo Argenton (talk) 21:48, 15 April 2018 (UTC)

@Rodrigo Tetsuo Argenton: If the ID template is being used in categories, then it would be good to migrate the info to here (if not already here) and we can use commons:Template:Wikidata Infobox to show it there. For files, a lot of the work will become easier once structured commons is here, but for IDs that are present both here and there then we could try to match them up, and add image (P18) here, and "wikidata=" tags there. Thanks. Mike Peel (talk) 11:51, 16 April 2018 (UTC)

@Rodrigo Tetsuo Argenton, Mike Peel: before you start doing double work:

The monuments database indexes about 1,5 million monuments (stats). A lot of these id's are cross referenced with Wikidata already or that can easily be done. The monuments database used to index images too, last time it ran it was about 2,6 million images (more info). I haven't invested any time yet on removing the intermediate step. To explain that, now it's file -> id, id -> Wikidata, that could be file -> Wikidata. The reason I haven't done anything yet is Structured Data on Wikimedia Commons. This is a good set to convert once we have the initial release of that deployed. It's a bit of double work to add Wikidata id's now in template pseudo structured data and doing everything again a bit later.

I would wait a bit and in the meantime focus on improving items with heritage designation (P1435) and making sure all the items about monuments have at least one of these properties. Also the cross referencing effort probably could use a hand, but I don't know the latest status. Multichill (talk) 16:23, 16 April 2018 (UTC)

@Multichill: For files, I'd agree, better to wait for structured commons (although the latest changes to commons:Template:Artwork to auto-fetch info from Wikidata when given the qid are a huge step forward). For categories, structured commons won't impact those, so moving the IDs in those over sooner rather than later makes more sense. Thanks. Mike Peel (talk) 18:12, 16 April 2018 (UTC)

• Maybe you could use it to connect categories to Wikidata items.
  --- Jura 18:15, 16 April 2018 (UTC)
  • That’s probably quite easy and already done, but I’ll have a look anyway and see if new links can be made. Multichill (talk) 12:47, 18 April 2018 (UTC)

Model a primary source and maybe also quality

In Sweden the National archives released 100 million documents for free last month ==> we can now in WD have Primary sources like birth and death records as a source (example query)

Question: is there a best practice to model a primary source so that I can ask for

all birth dates for Swedish people not confirmed by a primary source born more than 70 years ago?

If not how do we model sources in the best way

1. type of source e.g.primary/secondary/compiled/....
2. quality of source
   1. High quality
      1. they have a well-documented quality system
      2. track record of delivering quality the last 10 years...
      3. by professionals mentioned as having "hallmark" quality and have very very high trustability?
   2. ???

P31=Norse human

When working on property:P2600 I found that one item is instanceOf Norse human Q24451723. There are many more humans linked via P31 Special:WhatLinksHere/Q24451723. Is this desired? 78.55.76.113 18:43, 17 April 2018 (UTC)

I don't think Q24451723 is needed or desirable, it can be done with ethnic group (P172) Norsemen (Q1211290). Subclassing humans would lead to the madness that is Commons categories and intersection categories, since humans can have a lot of different characteristics. Ghouston (talk) 21:56, 17 April 2018 (UTC)

Agreed. Not desired. Looks like a one-person wikiproject - Wikidata:WikiProject Norse - intent on turning all sorts of stuff (well, runestones, humans) into Norse Runestones and Norse People.

Books and Authors

I want some opinions. I created yesterday for litteraturbanken.se a proposal link...

As it looks technical possible to have one property for both books and authors I start feeling its better to split this property into

• Swedish_Literature_BookID

Any comments/suggestions?

My argument is that its conceptual easier implementing two properties- Salgo60 (talk) 05:29, 18 April 2018 (UTC)

"Better source needed" ?

Is there a way to indicate "better source needed" on a statement ?

For example, suppose I have a date and place of birth for somebody, from a genealogical website -- but it doesn't give primary sources. The family relationships are right, confirmed by multiple primary sources; the year of birth might be right - it matches the age given on the death certificate; though the date on the tombstone is a year earlier; and ages given on other official documents, such as census returns, immigration forms etc are all over the place; there's also a place of birth confidently stated on the genealogical website, that seems quite a long way from the family's long-term residence, but doesn't seem to have come from any other source I can see online.

The subject died in 1908, so there's no BLP issue.

I'd like to include the stated birth-place, but note that its ultimate sourcing is not clear. Is there an appropriate way to do this? On some wikis one can tag a statement with Template:Better source needed (Q6716717). Is there anything analogous here that one can do to mark a statement that could use better verification? Jheald (talk) 12:41, 19 April 2018 (UTC)

Found a line in an old newspaper. Turns out that the tombstone was right, the place was right, the death certificate was one year and one day out. But it would still be useful to think how to mark statements where improved sourcing is needed. Jheald (talk) 13:33, 19 April 2018 (UTC)

4 242 000 instances of human - SPARQL for Q5 externalid statistics

SELECT (COUNT(?item) AS ?count)
WHERE {?item wdt:P31/wdt:P279* wd:Q5}

Try it!

Only two Wikipedias have more than 4 million articles, namely enwiki 5.6 mio, and cebwiki 5.3 mio [13]. In the list de:Liste genealogischer Datenbanken Wikidata would be ranked 26 by number of human items.

Are there a sparql queries that could show

• how often VIAF (VIAF ID (P214)) and ISNI (ISNI (P213)) are used on instances of Q5

or even better

• lists quantities for each externalID that is used on any instance of Q5

According to Wikidata:Database reports/List of properties/Top100 total VIAF ID (P214) = 1181059, GND ID (P227) = 606095, ISNI (P213) = 541276, BnF ID (P268) = 401272, but these numbers are not restricted to instances of Q5.

92.229.165.74 13:02, 19 April 2018 (UTC)

SELECT (COUNT(DISTINCT(?item)) AS ?count)
WHERE {
  ?item wdt:P31 wd:Q5 .
  ?item wdt:P214 [] .
}

Try it!

finds 1,018,671 distinct humans with VIAFs. (1,027,083 uses of VIAF ID (P214) on humans as a whole). Jheald (talk) 13:13, 19 April 2018 (UTC)

Jheald, thanks a lot! I did for ISNI P213 and got 476,549. The SPARQL for both on one item gives 474,573, so there are ~2000 items that have ISNI but no VIAF:

SELECT (COUNT(DISTINCT(?item)) AS ?count)
WHERE {
  ?item wdt:P31 wd:Q5 .
  ?item wdt:P213 [] .
  ?item wdt:P214 [] .
}

Try it!

Do you know how to count two properties in one query, so it should give the VIAF = 1,018,671 and ISNI = 476,549 in one run? 92.229.165.74 13:24, 19 April 2018 (UTC)

This gets close, but it counts the number of different ISNIs and VIAFs rather than the number of different humans.

SELECT (COUNT(?isni) AS ?count_isni) (COUNT(?viaf) AS ?count_viaf)
WHERE {
  ?item wdt:P31 wd:Q5 .
  OPTIONAL {
    ?item wdt:P213 ?isni .
  }
  OPTIONAL {
    ?item wdt:P214 ?viaf .
  }
}

Try it!

Note that the run time is now over 40 seconds -- the maximum allowed for a query is 60 seconds, so that may limit how much more can be built in.

CirrusSearch issue returning pages in multiple categories

Hi

So I'm having some issues with CirrusSearch which I'm 80% sure I'm searching for the right thing and following the instructions correctly but am not getting the results I expect.

I'm working on a new version of Wikidata:Dataset Imports which has each dataset recorded on an individual page and using categories to organise the pages. I'm nearly done with this new version and once I've solved this issue people can use the page.

What I'm trying to do is run a search to find items that exist in both of two categories using the instructions here.

I've created a test page Wikidata:Dataset_Imports/test which is in both Category:Medical datasets and Category:Updated datasets and I'm trying to create a query in the search bar to find the page. I think it should be:

incategory:"Text document datasets" incategory:"Medical datasets"

However this doesn't give me any results..... Can someone tell me what I'm doing wrong?
