Anonymous works qualifiers

Museums and other collections have quite a few paintings for which the author is anonymous (Q4233718). To make this a bit more specific, they use qualifiers. I brought this up at Wikidata talk:WikiProject Visual arts#Anonymous works and feedback was positive. I propose to create these properties. For completeness sake I'll paste the original message.

We have anonymous (Q4233718) to be used with creator (P170). Usually we have a bit of information about this unknown author we want to include as a qualifier. The Rijksmuseum (Q190804) was so kind to share their collection manual. It's a 100+ document touching onto a lot of problems we face too, including anonymous works. I would propose to create the missing properties so we can properly qualify anonymous works. I'll list them here, between () is the Dutch original:

Attributed to (toegeschreven aan): object is not signed and there is a certain amount of uncertainty who the author is.
Workshop of (atelier van): to be used if the object was probably created by students or employees of the artist in the same workshop, possibly with help of the named artist.
Follower of (navolger van): unknown artists who works in the manner of the named artist.
Circle of (omgeving van): objects by an unknown author who lived in the same time as the named author in a similar style, possibly a follower or someone who had contact with the named artist.
Manner of (manier van): objects in similar style as the named author, but not necessary from the same period.
Forgery after (vervalsing naar): Forgeries trying to appear to be the work of the named author.
Possibly (mogelijk): To be used with objects with a bigger uncertainty about the author.
School of (School van): Unknown author with a style influenced by the known author or circle, active in the same period, but a student or follower

Discussion

The National Inventory of Cultural Property of the Maltese Islands is a register for cultural properties in Malta (Q233). There doesn't seem to be a Wikipedia article or even a Wikidata item right now, so see http://www.culturalheritage.gov.mt/page.asp?p=21406&l=1 for more information. There are other similar properties already (this should be added to Template:Cultural_heritage_properties if it gets created) and this information has been added by other people to images on Commons. I'd like to be able to add it to Wikidata too, so that it's more easily accessible to other people and projects. The site has a link to a PDF for each object (e.g. http://www.culturalheritage.gov.mt/filebank/inventory/00001.pdf for Ġgantija (Q216862)) but unfortunately it seems the URLs aren't predictable. I imagine they could be linked via reference URL (P854) though. The PDFs include information such as the location, when it was built, what it was used for, a description, a map and photos. The proposed name is a bit of a mouthful, so maybe using "NICPMI identifier" would be better, although it's far less obvious what that means. - Nikki (talk) 12:17, 15 March 2015 (UTC)

Awesome. I'll get the first matches uploaded now. Andrew Gray (talk) 21:01, 26 March 2015 (UTC)

...or not. We have a bit of a problem - the EMLO identifiers include both people and places. However, the URLs require you to state person or place - as a result, the identifier on Christiaan Huygens (Q39599) works fine, but the one on England (Q21) is broken. Any idea what we can do with this? @Magnus Manske, Charles Matthews, Pigsonthewing: Andrew Gray (talk) 21:06, 26 March 2015 (UTC)

A pragmatic solution could be to use this for persons, get the catalog done for those and in the meantime put the places on ice. A second identifier would be needed, but the splitting of the catalog in two would be the main burden. Charles Matthews (talk) 21:25, 26 March 2015 (UTC)

It seems the best approach. One problem is that we can't easily tell from the identifier which is and which isn't a person. I wonder if mix-and-match can look for p31 before writing any values? Or we could add person/ to the front as needed. Andrew Gray (talk) 21:29, 26 March 2015 (UTC)

We've hit this problem a few times, recently. One solution, as noted above, is to have two properties. The other would be to develop more sophisticated "formatter URL" processing. The latter would take time, of course. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:36, 26 March 2015 (UTC)

Mix'n'match stores both the ID and the URL, so I can either prefix all IDs with "person" etc., or split all non-person ones into a new catalog and rename this one "EMLO person", and someone change the property accordingly. I tend towards the latter, but both is possible; but we should decide before we do anything. --Magnus Manske (talk) 22:30, 26 March 2015 (UTC)

UPDATE Split the mix'm'match catalog into two, will import just the people. Someone request "EMLO location" property... --Magnus Manske (talk) 22:54, 26 March 2015 (UTC)

That suits, me, too. Storing value like "person/e0b46100-d5cd-44d0-b02f-4a64e277241e" would be a kludge, and would cause problems if their URL stucture changed later. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:32, 27 March 2015 (UTC)

Example	Vladimír Smékal (Q11909522) => 668
Format and edit filter validation	could be filtered to check that only digits are present (or, more strictly, that the entered value matches the above regular expression)
Source	Masaryk University Information System
Robot and gadget jobs	A bot will be regularly updating cs:Template:Učo na článek with tuples of form "person's identifier – name of related article on Czech Wikipedia" from Wikidata. This template is used within wikitext-format citations produced by the university's information system, e.g. [2] (click "Wikipedie" below "Citační záznam"), because the information system knows the ID but cannot know the Wikipedia article name. In the future, once it is possible to query other entity's properties from within a Wikipedia article, this importing will become superfluous because it will be possible to look up the article name directly on Wikidata.
Proposed by	Blahma (talk)

Discussion

There are currently 509 articles on Czech Wikipedia alone in categories cs:Category:Absolventi Masarykovy univerzity (i.e. Masaryk University alumni) and cs:Category:Vyučující na Masarykově univerzitě (i.e. faculty staff). All of these have their identifiers in daily use in the university's Information System and beyond. Masaryk University's Information System is a robust system powering that has been powering the whole university (~40,000 people at the moment) since 1998 and the person identifier (called učo in Czech) has been in use since 1999 and as of 2015, more than 440,000 people have been given a unique number. Having this ID in Wikidata will allow for smoother displaying of links to alumni and faculty profile pages and will serve as proof that a particular person is indeed the university's alumni. Masaryk University has recently partnered with a local group of Wikimedians within cs:Wikipedie:WikiProjekt Masarykova univerzita and therefore even more articles about notable people linked to the university are expected to appear in the future.

I will add the posibility for the editors or a bot to check for situations when the visibility of data linked through this identifier has changed and to hide/show those links in templates adequately. --Blahma (talk) 16:08, 16 March 2015 (UTC)

How to manage "uncredited"? ValterVB (talk) 13:16, 21 December 2014 (UTC)

Support I see value in this qualifier, also useful for when crediting authors who use various pseudonyms, etc. I have run into this exact conundrum as well. (@ValterVB:, I took the liberty of changing the property name to credited as.) Sweet kate (talk) 20:56, 23 December 2014 (UTC)

Comment Might this be better as a generic property such as named as, where the name of the target item, at the time the claim was valid, would be specified. Companies change their names for example, e.g. RIM became Blackberry, but should be referred to as RIM if that was what it was called at the time. Essentially, this is how simple wikilink templates work in wikipedia, you can provide an alternative name to be displayed instead of the article name. Danrok (talk) 14:58, 4 January 2015 (UTC)

Discussion

Motivation: (short proposal in the Japanese discussion page; disclaimer: I am not a native speaker, and have only limited skills in Japanese). Currently, the names of a Japanese people or places are only written in Kanji characters (Chinese characters) in Wikidata (in addition of kana/latin characters/numbers… if the official name use them). It is not possible to know from the name in Kanji how to read it without ambiguity. In the Japanese Wikipedia, the name in Kanji at the beginning is often/always followed by the pronunciation/reading in hiragana. Note that the names in foreign language can help, but it may not match the Japanese pronunciation (ex: 東京 is Tokyo in English, but in fact it is pronounced Tōkyō with two long o).

An alternative would be to enter these kana names as aliases of the names.

Proposed by: Fabimaru (talk) 09:47, 29 March 2015‎

Support As qualifier for any monolingual property with value in Japanese i.e. official name (P1448), birth name (P1477) or native label (P1705) etc. There is similar pinyin transliteration (P1721) for Chinese. Paweł Ziemian (talk) 18:36, 29 March 2015 (UTC)

Support. I don't know the languages, but would it make sense to only have one property for this or multiple? It seems like it should be multiple from the range provided. --Izno (talk) 20:35, 29 March 2015 (UTC)

I made a request for the creation of a new Property, but in fact I think that it will not be enough (so maybe all of you may agree with the need of having the kana names, but there is not concrete proposal yet). The names of a given Wikidata item can be present at at least 3 places: the label of the item (in particular the label in Japanese), the "alias" entries of the label, and also in other properties (like official name). For these 3 cases, when there is a name in Kanji (ex: 日本=Japan) there should be one or several associated names in kana (ex: Japan = can be pronounced both nippon and nihon!) that would explain how to read it. I cannot see a single way to store the kana names for these 3 cases. Let's review these 3 cases to see all the challenges:

For the label, I don't know where we would store it. In a property? (ex: kana version of the label). We could store
For the "aliases" of the label, there can be several names (ex: Emperor Hirohito), and each of them should have a kana version explaining the pronunciation. If we add the kana as additional aliases, there will be no way to make the relationship between the Kanji name and its pronunciation(s).
For the properties (like "Official name"), it seems a good fit to use a qualifier (I just discovered this concept, I am not a seasoned user of Wikidata).

So I don't know how we could handle the names in the section "label". Any idea is welcome. Fabimaru (talk) 18:50, 4 April 2015 (UTC)

From my experiences labels and descriptions are usable only for searching data, and nothing more. Any valuable data need to be stored in properties. BTW there is Hirohito (Q11709840), and I think it is good place to store native label (P1705), which can be extended with qualifier of this proposal type data. After reading an article about Hirohito (Q34479) I think, you can put two values in official name (P1448), one "裕仁" and second "昭和天皇", with qualifier start time (P580) equal to date of death (P570). When this "nama in kana" property is ready, all presented examples can be extended with new qualifier with corresponding kana values. Paweł Ziemian (talk) 19:58, 4 April 2015 (UTC)

There is a special alphabet (the International Phonetic Alphabet (Q21204)) to describe the pronunciation of words in english and other languages and we don't bother to include this in wikidata - though we may in the future. Does the japanese wikipedia have names in kana for places and people outside japan?

Labels and aliases are used for searching for items. If the 'name in kana' is likely to be used as a search term then it should be included as an alias.

We have a lot of 'name' properties (a search for "P:name" will find most of them) and this property should be used as a qualifier to all of them. Filceolaire (talk) 02:39, 10 April 2015 (UTC)

Support This property is essential data in Japanese language. In person's name or place's name, there is generally single kana. But in other concepts, there can be some kana. In Japanese Wikipedia articles, kana are always/almost wrote at the first sentence within round bracket. (P.S. I'm native Japanese speaker. But it does not mean specialist. I'm just a average speaker.)--Was a bee (talk) 19:03, 31 March 2015 (UTC)

@Caliburn: - Sorry, but in fact I did not make it clear that I finally did not think that my initial proposal would solve anything. I think that the contributors agreed with the problem to be solved, but the way to solve it is still to be defined precisely.

The problem I was trying to solve was to store for each Japanese name (either in the label, the aliases and the properties) one or several readings (in kana characters). As mentioned above, it seems that a new qualifier would solve the problem nicely for the Properties containing a name (like "Official name"), so ~~that would be a new proposal (I guess I should do a new proposal for that)~~. Remaining problem: what do we do with the Japanese names stored as a label or an alias? I don't really have an answer. Would the contributors have to copy the name from the label into a property in order to be able to provide its associated reading(s) (via the new qualifier)? For example: for a temple, if a contributor wants to enter the reading, he will have to copy the name in a Property native label (P1705), and add one or several qualifiers. It seems a bit tedious, but the data model looks fine. - Fabimaru (talk) 18:53, 11 April 2015 (UTC)

I am afraid that you can do nothing more with label and aliases than adding more aliases, for example new aliases in kana. In fact all of them describe alternative names (spoken and/or written) of the item. Paweł Ziemian (talk) 21:19, 11 April 2015 (UTC)

(NB: I thought that a special type of new Property was required for qualifiers, but it is not the case) Here is what I understand with the new type of Property (I hope it is correct, and that the Wikidata contributors will understand it the same way): if it is added as a name in kana (P1814) instance of a given Item, then it describes the Japanese label of the item. For another Property containing a name (like official name), a contributor should add a qualifier name in kana (P1814) to it. Thanks everyone for your collaboration. - Fabimaru (talk) 20:23, 12 April 2015 (UTC)

Support but I don't agree with adding "code" to the property name. The "C" already means "code" and I don't think it makes it any clearer. If you're unaware of the musical work meaning, you'll probably just read it as "international semantic web conference code" and be none the wiser about what the property is supposed to mean. If you are aware of the musical work meaning, I can't imagine a situation where it would actually be confusing. If it really is a problem, why not copy the way ISRC (P1243) is done?

IPI Code

Done: IPI name number (P1828) (Talk and documentation)

Description	The IPI Code (Interested Parties Information) is an international unique identifier for composer, author and other relevant parties. It is linked to the ISWC code (please read the previous proposal), adopted as international standard ISO 15707. Each item in the registry has an ID which is accessible via this page and through other online resources. The authority, with associated member in more than 120 countries, provides a unique IPI code. This code could be extremely useful during an Authority control process for composer and author of creative works.
Represents	Interested Parties Information (Q6046224)
Data type	String
Template parameter	an IPI code could be used in any infobox for author and composer
Domain	author, composer, etc.
Allowed values	alphanumeric string (IPI code)
Example	Brian May (Q15873) => 00087038166
Format and edit filter validation	11 digit number can be validated with edit filter Special:AbuseFilter/17
Source	IPI code, The registration authority, en:International Standard Musical Work Code
Robot and gadget jobs	validation
Proposed by	79.40.127.123

Discussion

The IPI code are ISO supported via the ISWC, it is unique and used all over the world. For a test, try to search "May Brian" - or any other composer you know - via this page. It could be extremely useful to undoubtedly identify author and composers. We do not currently have a similar authority control for author and composer. This code could also help to provide an unambiguous relation between a creative work and the legal holder of copyright. --79.40.127.123 22:54, 27 October 2014 (UTC)

Discussion

Identifiers seem to be popular on Wikidata, and the Federal Election Commission (Q2705072) (FEC) identifier would be a good one to include. The FEC is responsible for regulating campaign spending of (federal) political candidates, political parties, and other committees involved in federal election processes. As part of this, the people and entities regulated by the FEC submit quarterly/annual campaign disclosure reports, detailing their revenue, expenditures, and sources of political contributions. This information is a valuable part of U.S. political discourse—people are interested in knowing how much it costs to "buy" a seat and who is "buying" politicians. Having each member of Congress (and in the future, former members and also notable PACs / political parties) associated with their FEC ID could be worthwhile. The FEC ID number is also used by the Sunlight Foundation in its myriad APIs, which are also highly reliable and valuable sources of information for Wikimedia projects. (Note that I have opted for just "Federal Election Commission" and not "U.S. Federal Election Commission," since it appears this is the only agency in the world with that name).

@Brya, Succu: We will even have multiple labels in each language, so the lists will get long and will need qualifiers. One of the weirder examples might be: strawberries (Q745): Common name -> "Ananas" (Qualifier: used in -> Eastern Austria). --Tobias1984 (talk) 18:54, 13 March 2015 (UTC)

Yes, this could become a long list. Adansonia digitata (Q158742) has a lot of local names. Reliable sources are important. --Succu (talk) 19:00, 13 March 2015 (UTC)

Indeed. This is why the distinction between common names and vernacular names is important. A well known example is Bellis perennis in the Netherlands: it has one (official) common name, but if everything is counted that ever was used this will run up to (IIRC) something like two hundred 'names'. In at least some countries (I don't know how many, but it is not rare) there are official common names for plants. For example, the USDA Plants site (see above) has official standardized US common names for plants. When botanists were inventorying in the Far East they quickly gave up on trying to record vernacular names, there were so many it was obviously hopeless. - Brya (talk) 06:08, 14 March 2015 (UTC)

BTW: Wikispecies has a Vernacular names section. --Succu (talk) 10:48, 18 March 2015 (UTC)

Eventually the Labels for these should be changed to their common names, at least for those languages spoken in the range of the creature, with vernacular names listed in the aliases.

Krestinin (talk) 05:04, 13 December 2014 (UTC)
Support. Per Ivan; distribution maps and range maps are qualitatively different. Note that biology often has distribution maps and history often has range maps, so this is not a matter of history vs. biology. Compare File:Roberts.png (distribution map) and File:Modern_Greek_dialects_en.svg (range map). And distribution maps can be used for taxons; see e.g. http://www.gap.uidaho.edu/bulletins/18/species.pdf. Andy, what do you think? Emw (talk) 15:35, 27 December 2014 (UTC)

A lot of these photographers are the same as the ones listed in the DiMu service, that is a lot of the photograpers of historic images we are using from Norway. About 1000 of the photograpers are listed in Wikipedia. I have not verified the number, it is from a discussion some time ago. The category holds slightly more than 5000 entries.

Discussion

Motivation: This is the id used by Sentralt Stedsnavnregister (SSR) in Norway for tracking the location's names. One location can have several names, and this id will be used as a qualifier for each one of them. Some background at Sentralt stadnamnregister (SSR). This property proposal could have been placed under Wikidata:Property proposal/Authority control as it is as much a matter of authority control on the place names and their ids.

The fields for status and use value has not been proposed to materialize as those fields are process descriptors. In Wikidata I assume we only want to list the positive outcomes from the process, that is the names that are valid and official.

Proposed by: Jeblad (talk)

This id is the second one that will make it possible to track the locations and place names used by the real authority on such place names in Norway. It is possible to only source each of the written forms, link them to the "faktaark", and then only keep the "SSR ID" for inference purposes. That could be good enough. Jeblad (talk) 13:13, 7 April 2015 (UTC)

Jeblad Can you complete the example - i.e. what are the IDs for the various names of Q397876? Filceolaire (talk) 20:48, 10 April 2015 (UTC)

Filceolaire Added some examples by reusing a previous simplified notation. Note the use of authority (P797) in Glittertind (Q397876) for the name of the executive authority. I think we need some qualifiers for status changes, but those should be more general. I think something like a qualifier "Official name status" a "Official name status change date", both covering the time from the change until the next listed valid entry. This could although be even more general. "Status" and "Status change date" perhaps. Could be that something like that is already defined, I haven't checked. Jeblad (talk) 23:16, 14 April 2015 (UTC)

- Given that the Japanese Wikipedia already has plenty of blood type data, I doubt that adding the data would be legally problematic, but IANAL. (Pinging @Micru, who commented on the earlier proposal that adding the property could have legal repercussions.) --Yair rand (talk) 01:28, 20 April 2015 (UTC)
You can say that only for Japanese people, but the situation can be completely different in another country meaning that if one person complains in Germany about this kind of data, we have a problem for all cases of Germans people and perhaps even from Europe. That's the problem of different laws applying to the same system. Take the example of Google: the Europe law requires the possibility for persons to ask the deletion of some data. Google has to do it even if the servers were located in US and if no US law was requiring similar option. Snipre (talk) 13:27, 20 April 2015 (UTC)
- @Wylve: Because no American complains until now. My problem with that property is the use according to certain legal conditions and so no applicable to most of the items concerned by the property. This means more maintenance work for a small application. For me we can proceed with this property only with a comment from legal team of the WMF to ensure the minimum of problems in the future. Snipre (talk) 13:48, 20 April 2015 (UTC)
Oppose Oppose unless a comment form the legal team of WMF says no risk. Snipre (talk) 13:48, 20 April 2015 (UTC)
~~Oppose~~ I'm pretty sure this will be a problem in the US, and I suspect even more problematic in Europe. So I concur with @Snipre just above: unless the legal team says there's no risk, I wouldn't want to go there. (PS: For my own education, would someone mind telling me why this is commonly publicized in East Asia, and why people care? I'm not saying it's wrong, only that it's a cultural issue not within my experience.) StevenJ81 (talk) 14:50, 20 April 2015 (UTC)

@StevenJ81: Maybe you can find your answer in the wikipedia article en:Blood types in Japanese culture . Btw: "Facebook in many Asian countries allows users to include their blood type in their profile." (Quote from the beforementioned article) (Maybe additionally this recent article http://luckyturtles.com/2015/04/17/korean-blood-type-superstitions/) I just want to add, if you ever played a Japanese or Korean video game, read a manga or saw an anime series, you will see that there is blood type for all characters. And most East Asian stars show there blood type on there websites. --Christian140 (talk) 17:46, 20 April 2015 (UTC)

Support for usage in ja Wikipedia. --- Jura 18:12, 20 April 2015 (UTC)
Weak support (despite earlier thread). Seems to be a cultural issue. From my (Western, specifically: Swiss) point of view, the idea would seem almost ludicrous: I can think of no person except some of my closest family members where I'd have the faintest idea about their blood type, and it's generally not the kind of data that gets published here. However, it seems to be different in some Asian countries. Apparently, e.g. the Japanese Wikipedia already lists blood types as widely known and seemingly uncontroversial data. It seems it would make sense for Japanese (and Korean and...?) people to store this data on Wikidata, too. But as Pasleim says: "The problem is that we can't restrict properties to certain domain". Not technically, at least. But maybe it could be restricted by guideline? E.g.: Only add this property to items for Asian people where the blood type is publicly known. Gestumblindi (talk) 22:41, 20 April 2015 (UTC)

@Christian140, Visite fortuitement prolongée, Wylve, Yair rand, Snipre: @StevenJ81, Jura, Gestumblindi, Filceolaire: Done blood type (P1853), with datatype = item (items have also been created).

As someone entrusted with the "property creator" role, it falls to me to weigh up this evenly-divided (numerically speaking) discussion. I have done, so, having also read the previous discussions cited above.

To paraphrase, there seem to be two grounds for opposing:

Legal issues
Lack of use outside Asia

With regard to the first of these, no evidence was offered that, for example, the WMF-hosted Japanese-language (note: not Japan-hosted) Wikipedia, edited and read by Japanese speakers from every continent, has had a problem with publishing this data. The suggestion that we must first obtain WMF approval before creating a property would set a bad precedent. The WMF can, of course, instruct us to remove any data held illegally, should such a case arise. Again, no evidence that holding publicly-referenced blood-type data on US servers is illegal was offered, and I found such arguments uncompelling. I also note that the blood types of US presidents are available online.

With regard to the second point, I am mindful that WMF projects are often criticised for systemic bias towards western culture. We must not perpetuate this. I again found the argument uncompelling.

I also note that the discussion in archive 22 had a majority in favour of creating this property.

Accordingly, I have created the property. Should anyone wish to ask our colleagues in the WMF legal team to review my decision, they are welcome to do so. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:59, 25 April 2015 (UTC)

@Pigsonthewing, that is your prerogative, of course, and I'm not going to go invoke the legal team.

I do believe you should add a constraint along the lines that if the person is still living, the information must have been made available somehow by the person himself/herself (on an own-controlled website, in an interview the person himself/herself gave, and the like). I imagine that most times when this information is available that's true, by the way.

This constraint would be stricter than the requirement laid out in WD:Living people itself, of course. But I cannot think of a single reason that this information would be publicly important, even for a very public personality, unless the person himself/herself chooses to disclose it.

This would be a reasonable compromise between the position some of us have—that it's not really anyone's business, and may violate privacy laws—and the position that others of us have—that many people make it public, and therefore there is no reason not to include it. StevenJ81 (talk) 15:07, 27 April 2015 (UTC)

I fail to see how such constraint could be done. Visite fortuitement prolongée (talk) 19:55, 27 April 2015 (UTC)

How enforceable it would be is a good question. But some properties do have constraints attached, and various admins, editors, bots, etc. do clean up violations. See, for example, Wikidata:Database reports/Constraint violations/Mandatory constraints. This wouldn't be such an easy one; one would have to go back and check the original source to see if the individual has actually given permission. StevenJ81 (talk) 13:47, 28 April 2015 (UTC)

Comment Thanks to Andy for creating this. To gather some practical experience (and expand our database), it would help if everyone else participating in this discussion would be kind and attempt to contribute the property to 5 to 10 items. --- Jura 15:17, 27 April 2015 (UTC)

Can you give a clear definition of what are the eligible voters? What is the difference with the registered voters? --Dom (talk) 05:50, 17 April 2015 (UTC)

I see registered voters as a subclass of eligible voters. In most types of national elections, the eligible voters are registered voters, as they register with their governments. But with other types of elections, like party elections or elections that do not involve voting by the public but an election committee, the voters are not strictly "registered". So eligible voter includes registered voters, but I didn't choose to use to word "registered" as that would be too limiting. —Wylve (talk) 17:00, 17 April 2015 (UTC)

Support Eligible voters, electorate (P1831), and ballots cast are all separate and distinct statistics for elections. Each has value and is perfect data for WD to have if it is available. Exact definition of who is 'eligible' and who is 'registered' is obviously dependent on local laws related to elections, but none-the-less they are important data to maintain and be able to access when researching elections.

Proposed by	Jheald (talk)

Discussion

Same logic as the proposal two entries above, viz:

When harvesting information from categories it is important to be able to identify "auxiliary" items intentionally included in the category, that in general will not conform normal category inclusion criteria specified by is a list of (P360).

Such auxiliary items should also be white-listed, when identifying category-member items that appear to be in constraint violation of the category's is a list of (P360) criteria, that should either have necessary missing properties added, or their category membership reviewed.

The most common type of such auxiliary items in categories are survey articles on the topic of the category as a whole, identified by category's main topic (P301). The second most common type of auxiliary item is a list paralleling the membership of the category, as proposed two entries above. This property would be used to identify any other auxiliary item in the category. Jheald (talk) 18:24, 27 February 2015 (UTC)

Oppose. We will be harvesting info once only from each category. After that wikidata will have more info than any one wikipedias category system. As such this 'black list' of items that the harvesting tool should ignore should be part of the harvesting tool. There is no need to make it a permanent part of wikidata. Filceolaire (talk) 14:24, 10 April 2015 (UTC)

Per my more extensive comment on the property below diff, thinking that an entire category tree will be absorbed in a single hit is fundamentally naive. Both the category system and Wikidata are likely to continue to evolve and grow in parallel for the foreseeable future, so it is sensible to explore how build bridges between the two, and how each can sensibly support the other on an ongoing basis.

Besides, the information that would be captured by this property is precisely the kind of looser association contained in the category system (eg between Category:Harvard University alumni (Q7234382) and Harvard alumni health study (Q5676636)) that would excluded in most simple category extractions. On the other hand, the record of the association is useful, and prompts an obvious constraint check on Harvard alumni health study (Q5676636) to see whether we have any property on Harvard alumni health study (Q5676636) (or short chain of properties leading from it) that would relate it to Category:Harvard University alumni (Q7234382).

Either way, it would certainly be useful for it to appear to be a regular property, so it could be included in WDQ 'tree' and 'web' queries.
Proposed by	Jheald (talk)

Discussion

One of the great possibilities opened up by specifying category inclusion criteria using is a list of (P360) is the chance to deliver automatically "augmented" categories, if the reader of a particular wiki so chooses -- ie to give the option to add to the regular view of the category (if the user wishes) all those articles not in the category but that fit the category inclusion criteria as specified in the P360 that are blue links on that wiki; or all the potential articles that could be in the category that are red links. (Or to generate either list as a report for a particular category).

To do this, one needs to be able to exclude items which match the inclusion criteria, but also match the more specific inclusion criteria of one of the sub-categories of the category. To do this, one needs to be able to discover what are the sub-categories of the category, in that particular wiki. And it is convenient to be able to find that by asking Wikidata, the same place as all the other information about the article-items and the category.

So this proposal is for a property to track those parent-child relationships; one could track either parentage or progeny (or both); but it seems most convenient to specify parentage, just as we do on the wikis.

I should underline that this property is intended to be descriptive, to help bots and automated systems, not normative -- it is to record how the wiki-categories are structured in each particular language, and not any single way that they in any sense they ought to be structured. Jheald (talk) 19:19, 27 February 2015 (UTC)

Until someone puts a bot together to work keeping Wikidata's copy of a particular wiki's category structure up-to-date, this is a flat oppose as unworkable. Additionally, seems to duplicate data that is inconsistent between the wikis, which I don't think we should be attempting to do. Maybe there is some sense in a prescriptive category system (which is better defined by relationships already defined on the category's main topic), but there wouldn't be consensus for that I don't believe. --Izno (talk) 17:15, 9 March 2015 (UTC)
Oppose, per Izno argument. Visite fortuitement prolongée (talk) 20:12, 31 March 2015 (UTC)
One category can have several parent categories (such Category:Dutch painters (Q6486661) and Category:Portrait painters (Q12981746) for Category:Dutch portrait painters (Q13421910)). This is not an issue.

But the data will be differet for each Wikimedia project. This is a huge data size issue.
And the data is not stable (like a birth date). A weekly/daily/real time copying/import will be needed. This is a huge data rate issue. Visite fortuitement prolongée (talk) 21:32, 2 April 2015 (UTC)
@Visite fortuitement prolongée: Is it really such a data size issue, to add a stated in (P248) qualifier (or similar) for each wiki the category applies to? A large amount of data, perhaps; but not a horrific amount, surely. Jheald (talk) 21:58, 2 April 2015 (UTC)
I don't know. Lets try a rough estimate:
currently about 10,000,000 items in Wikidata

currently about 300 Wikimedia Foundation project (Q14827288)

400 B/category property

400 B/qualifier

if 2 categories/item on average

if each category has 10 interwiki links, so 10 qualifiers/category property on average

then the qualifiers would weight: 10,000,000 × 2 × 10 × 400 B = 80 GB

With more of all: 20,000,000 × 5 × 200 × 400 B = 8 TB

And there is the history. Wikidata keep memory of revisions.

And Wikidata do not raw store the datas. It envelop/coat them someway.

Visite fortuitement prolongée (talk) 21:03, 3 April 2015 (UTC)
@Visite fortuitement prolongée: According to WDQ there are currently 2.5 million items identified as instance of (P31) Wikimedia category (Q4167836) -- so the data requirement per your calculations above would be 20GB, not 80GB.

One of the beauties of Mediawiki is that to record the history, only the diffs are required. So that probably only adds say a factor of 3 to the storage cost.

Also note that there is a "long tail" effect here -- as one goes down the tail increasingly many of the categories become very specific, and more likely to relate to only a single wiki -- this again will tend to deflate your estimates (and is likely to remain true, even as if other languages 'catch up' to some extent in adding categories -- which they may or may not do.

So overall then, an estimate of 80GB including history (or 20 GB for the live data) is probably more realistic. To be sure, this is a substantial amount of data. But it is not a monstrous amount; and I submit that, even without some direct virtual system, this model would still be well worth such storage, for the ability to query wikidata information and WP category information together in a single unified integrated way, and to use it to augment and improve what is currently presented on Wikiepdia category-view pages.

As a side-note, thanks to the effect of Moore's Law on data storage, I believe I am correct in saying that even with the steady multilingual growth of Wikipedia, and the inexorable increase of history, both the cost and the physical size of its storage have in fact been steadily falling consistently over the last several years. So this should be seen in perspective. Jheald (talk) 08:33, 10 April 2015 (UTC)
Yes, I forgot that this section is about a proposed property only for categories, thank you for the corection.

Also, if I understand correctly https://dumps.wikimedia.org/wikidatawiki/20150307/ , it say that the last month size of the data of Wikidata, history included, was 27.7 GB. Then adding "80GB including history" would be a 285 % increase of the size. Visite fortuitement prolongée (talk) 15:01, 12 April 2015 (UTC)

Support Agree with User:Izno that we need a bot, but that doesn't make the property unuseful. Remember that most Wikidata data has been copied from Wikipedia.

"Inconsistent between the wikis" is patently false. Nobody has ever claimed or designed a global category system across all wikis, and it's natural that each wiki's category system reflects local differences or priorities. If we accepted the argument that categories are not useful because they are different across wikis, we should also declare inter-language links useless, because there's no 1:1 correspondence between them. Eg consider
- mortar and pestle (Q18341850): no wiki.
- mortar (Q45778): enwiki en:Mortar and pestle???, dewiki de:Mörser (Werkzeug)
- pestle (Q907209): dewiki de:Pistill.
- muddler (Q1316130): dewiki de:Stößel.
The categories are in fact very useful data and Wikidata should reflect them at some point. DBpedia has them (as skos:broader, whereas each category is a skos:Concept). --Vladimir Alexiev (talk) 06:29, 2 April 2015 (UTC)

@Visite fortuitement prolongée: Labels also change on a daily basis and are not sourced. Yet they are very important. --Vladimir Alexiev (talk) 07:59, 7 April 2015 (UTC)

There are three fundamental problems, as I noted:
One is that the data changes in an unstable fashion. Categories are added and removed on a daily basis from other categories, meaning these are not facts or even statements which have permanency, or which even you can put a truth test to on one day and get the same the next day. Our "import" of such categories would be idiotic for this reason alone, frankly. Even a bot is a bad solution to this problem because it ends up being thousands of edits a day (or more) just to keep up. The data isn't useful enough (though it might be interesting).
The second is that a category in wiki A will not have the same parent categories as in wiki B. This is a problem from our point of view because it turns a query regarding this into a mess (without qualifiers).
Third is that we end up duplicating data nonsensibly in two ways: one in that we're duplicating the main topic's data almost item for item, and two, we're duplicating each local wiki's data. Neither are desirable.
I'm going to respond to one particular point: "If we accepted the argument that categories are not useful" — nowhere was this argued (as I think most would find such an argument laughable). I did argue that this property is not useful. --Izno (talk) 17:47, 3 April 2015 (UTC)
@Izno: If you accept that categories are useful, don't you think Wikidata should reflect them somehow? --Vladimir Alexiev (talk) 07:59, 7 April 2015 (UTC)
No. Fundamentally, it comes down to "can we describe the topics themselves, rather than putzing about with categories"? has part(s) (P527) could describe what components are in a food item; that's useful because it tells me the kinds of food that I might find table salt (Q11254) in. A property assigning a food item to a location of origination would be interesting; that's useful to a historian. A property assigning a food item to a method of preparation would be interesting; a cook or some such might want to look at different ways to make a food item. subclass of (P279) would be useful to describe a taxonomy of foods (Macaroni and Cheese has part(s) (P527) Macaroni, Salt, Cheese; Macaroni is a subclass of (P279) a pasta is a subclass of (P279) food), which probably satisfies your need best. And so forth. Categories, on the other hand, do not give me an explicit relation between an item in that category and some parent/sub category, and so at best I'm left with vague or inconsistent data/relations and at worse I'm left with wrong data/relations.
Wikidata can probably help you and your specific use case. It's just that you haven't tried to go about getting help in the way that will most benefit, well, everyone. What kind of data do you actually need to work with? What kind of properties does your project/do you think are actually interesting about foods? That's the kind of information we should capture. --Izno (talk) 19:14, 10 April 2015 (UTC)
Oppose. Wikidata is not here to describe the wikipedia categories. Wikidata is here to describe real world concepts. The wikipedia category system does work as a sort of primitive wikidata and does contain useful information. That doesn't mean wikidata should duplicate the category system. It means that wikidata should harvest the information that is useful and translate it into wikidata statements using wikidata properties about real topics. Once this is done wikidata will have much better information than the categorisation systems do and categorisation can be left as a quaint legacy system to be used by wikipedians who don't want to migrate to using wikidata. Filceolaire (talk) 14:50, 10 April 2015 (UTC) OK. Jheald you have convinced me (see comment below). Support. Filceolaire (talk) 18:07, 11 April 2015 (UTC)
@Filceolaire: The sheer arrogance behind that statement is breathtaking. Wikidata is here to describe anything that we want to describe, which includes anything which would be helpful to other projects. The category system will continue to persist on Wikipedias, and will continue to develop in parallel with Wikidata, for the foreseeable future. For all its shortcomings, it even has some advantages over Wikidata -- the speed at which new categories can be defined or subdivided, the ease with which relevant free-text information can be added to the category view page, the informational value of hand-made hierarchies adapted to the specific data, even the very looseness of the categorisation system which can allow related articles to be discovered even if the nature of that relatedness may be complex would be hard to accurately define in Wikidata. So the question should be how can the two systems best be helped to support and enhance and inform each other.

Wikidata can be used to support and improve Wikipedia categories -- if properties like "parent category" are available -- eg by giving a place and environment where the natures of categories can be described and documented in a structured way; or by making it possible to suggest content that could be used to automatically augment and improve existing category returns. This would be of real value to Wikipedians working with categories, which in turn would give them a significant motive to learn more about Wikidata, and get involved here, to improve an output that they were interested in.

On the Wikidata side too, it is naive to think that all the information in a particular category tree can be absorbed into Wikidata in a single hit. Sure, one might capture the most obvious memberships. But the sheer flexibility of the category system, and its continuing hand-edited evolution, means that it will inevitably also include less obvious associations and new associations to be added in turn. Plus at the moment, nobody even knows which categories have been mined, or for what, or how complete that extraction was -- so anything that makes questions like that easier to analyse would be of use.

Thinking of categories as a 'quaint duplicate legacy system' that Wikidata will somehow bury is a fundamental misconception, as well as incredibly hostile to what is still the overwhelming majority of Wikipedians. Instead, much better to think how drawing on Wikidata can help the existing category system evolve, until perhaps it becomes primarily Wikidata-driven. Jheald (talk) 21:52, 10 April 2015 (UTC)

Discussion

Motivation:

Proposed by: Filceolaire (talk) There are many cases where the structure of wikidata means that there isn't always a one to one match between the articles in some wikipedias and the wikidata items and so it is difficult for a wikipedia to find the sitelinks to relevant articles in other languages where the article names are slightly different. This property will help in some of those cases. Filceolaire (talk) 00:12, 13 March 2015 (UTC)

Comment This could be solved if a link to a redirect page was allowed. For example Emma Lockhart (Q448108) wikilink is a redirect to Ace Ventura, Jr.: Pet Detective which is ideal. This was only possible because the link was made before the page became a redirect. Periglio (talk) 01:19, 13 March 2015 (UTC)
Support We need something in place to allow multiple links to the same wiki article. I have noticed a tendency on Wikipedia to merge biographies into a single article. Periglio (talk) 01:19, 13 March 2015 (UTC)
This looks like a pragmatic scalable solution. Multichill (talk) 08:36, 13 March 2015 (UTC)
~~Oppose~~ Comment A better solution is to allow sitelinks to redirects, with automatic reports possible that they are redirects and where they redirect to. Manual tracking of such redirects is likely to be sporadic at best, and unlikely to keep up with changes made to the different wikis. Trying to maintain a property like this by hand is not work that is worth doing. Jheald (talk) 09:31, 13 March 2015 (UTC)
- Jheald I used to think that too but now I think this property will be easier to maintain than redirects in 250 different languages. The advantage of this property is that once it is done for one language it is available for use in every language. Filceolaire (talk) 10:31, 13 March 2015 (UTC)
- It will also mean we can split items like 'the murder of Foo by Bar' into three separate items without having to worry as much about messing up the sitelinks. Filceolaire (talk) 10:39, 13 March 2015 (UTC)
  - @Filceolaire: Reducing my oppose to a comment, because on reflection it probably is useful to track on Wikidata how "redirects with possibilities" (as en-wiki tags them) are being used.
  However, I don't see this as an alternative to sitelinking to redirects, just a way of describing them. But just to be clear, are you suggesting that the long-term aim would be for a wiki-page to automatically be augmented with interwiki links to fallback pages using this property, if there were no interwiki link? That would be quite a transfer of control away from wikis, as to what redirects they want to exist, and where they should point to. Jheald (talk) 22:46, 13 March 2015 (UTC)
  - [User:Jheald|Jheald]] Each wiki would have the choice to just show the sitelinks on the wikidata item (including any links to redirects) or to show these sitelinks plus sitelinks found using this wikidata property. Filceolaire (talk) 17:17, 14 March 2015 (UTC)
Comment Like Periglio and Jheald, I think it would be simpler to allow links to redirects so I'm not convinced this is needed. Pichpich (talk) 16:13, 14 March 2015 (UTC)

It is a suggestion from the wikidata community as to how we think wikipedias - especially small wikipedias with less resources - might manage the problem of missing sitelinks due to missmatches between the scope of different wikipedia articles. If a wikipedia feels it has the resources to manage redirects themselves then they can decide to ignore our suggestions. Filceolaire (talk) 20:41, 19 March 2015 (UTC)
  - @Filceolaire: Then I think we better should use the existing relations or Simple Knowledge Organization System (Q2288360)   inspired property. For example, for the Bonnie & Clyde project, we know that Bonnie is a member of the duo. A lua template could automatically do the suggestion that if the article about the part does not exists, then a good candidate for the redirect about the whole if it exists. TomT0m ^(talk) 14:15, 22 March 2015 (UTC)
    - TomT0m that works for duos but there are a lot of other types of group articles - trios, families, partners, groups, lists of characters in a book, taxonomic genus, municipalities containing samename towns, three battles with the same name that occurred years apart, two castles on an island in the Hebrides, etc. Having a property to tell the template how to deal with this seems a lot easier than hoping the template is smart enough to spot all the cases with no false positives or false negatives. Filceolaire (talk) 16:45, 22 March 2015 (UTC)
      - @Filceolaire: I don't think you are right. Our properties are generic. So duos and trios are exactly the same things, as families or partners, as all part/whole relationships. For geographic entities, why not the most little entity that contains the entity we want, this seems a good criteria. It seems a lot more efficient in most cases that to put a property, a few smart choice in the template, guided by generic properties, could solve most cases without hoping or doing anything besides. TomT0m ^(talk) 17:25, 22 March 2015 (UTC)
        TomT0m I agree that this will take care of most of these cases but there are still the strange ones where english wikipedia has chosen to group thing together because they have the same name. "three battles with the same name that occurred years apart, two castles on an island in the Hebrides," aren't just random ideas - they are real examples on en:WP that I have come accross while trying to sort out wikidata sitelinks. They are not anything that will ever be linked by any sensible ontology but without the hint provided by this proposed property the other language wikis won't have links to these english articles which are actually more informative than any of the other language articles.
        
        I will, however, in future, create WP redirects when I come across these weird cases and sitelinks to the redirects now that I know how to do it. This is a workaround that doesn't need a new property.Filceolaire (talk) 20:37, 22 March 2015 (UTC)

@Filceolaire: "It is a suggestion from the wikidata community as to how we think wikipedias - especially small wikipedias with less resources - might manage the problem of missing sitelinks". Well, I'm not sure if we should "suggest" things, we should add statements based on sources, not opinions. For example, enwp tends to redirect "Non-notable minor planet no 123456" to "List of minor planets (123000-123999)". Such linking looks very frustrating to me, since it gives no information at all. I would prefer a link to "Main belt asteroid" or "Spectral class X-asteroid" instead.

Support per Visite fortuitement prolongée. Although it is just a workaround, it can help a lot with the problem without doing any harm, because we are just providing new data and it is up to anybody to use it or not. In the majority of cases these relations are language-independent, so they should be stored language-independently in WD, not in individual WPs nor as individual sitelinks to redirects. If a r WP wants to override a given relation, it can do it using the currently preferred solution, a sitelink to redirect. Finding an article in different language using any of existing properties is not an alternative. It would lead to unexpected results, because they have not been designed for this purpose.

Discussion

Motivation: Proposed by: Vladimir Alexiev (talk)

The Europeana Food and Drink project needs to find all Wikipedia categories and articles related to Food and Drink (with the intent of using these for classifying Cultural Heritage Objects on the same topic). I've searched for properties that can express this (eg topic, subject, tag), but none really seems to fit.

category combines topics (P971) is closest but it's defined very narrowly: only for categories and "combines topics" (whatever that means). Its true meaning is merely "X has topic Y" where Y is not the "main topic"
main subject (P921) is main subject only, and only for Works

It's best to redefine P971 to make it more general. Otherwise, define this new property. Vladimir Alexiev (talk) 06:11, 2 April 2015 (UTC)

@Vladimir Alexiev: You forgot topic's main category (P910)

and category's main topic (P301)

. If the items are classes then you can follow the class hierarchy with subclass of (P279) to find broader and narrower classes associated to that category, wich is a good start. TomT0m ^(talk) 10:29, 2 April 2015 (UTC)

@TomT0m: This (pair) is one of the inappropriate properties that I considered. It's limited to article~category only and it's 01:01 (there cannot be more than one on either side of the property). My proposed "topic" is applicable to any item, and doesn't have such isomorphic flavor. Looking at my examples: Category:Food and drink (Q5645580) doesn't have topic's main category (P910) (since there is no category Chipotle); and Europeana Food and Drink (Q19723898) is not a category at all. --Vladimir Alexiev (talk) 10:37, 2 April 2015 (UTC)

This sound like a post-it, which would be a very bad idea in my opinion. Do you know that you can edit the talk page of Wikidata items? Visite fortuitement prolongée (talk) 21:33, 2 April 2015 (UTC)

Of course I know I can write on Discussion, but I cannot get it in a structured way with WDQ or the RDF export. --Vladimir Alexiev (talk) 11:42, 3 April 2015 (UTC)
Oppose - overly broad (i.e., undefined), and can be solved by querying the Wikipedia's local categories. Heck, en:WP:AWB can do this. --Izno (talk) 17:12, 3 April 2015 (UTC)
Oppose. We have is a list of (P360) as well. I don't think we need any more properties for describing these special wikimedia pages which don't represent anything in the real world. If Europeana want to use wikidata to find items related to food and drink then they should forget about wikipedia categories and wikipedia lists and think about how they can use wikidata properties and statements to identify those items. If they have problems doing this then we need to look at what we need to do to solve those problems - not waste time trying to create some sort of second class wikidata using categories and lists. Filceolaire (talk) 02:20, 10 April 2015 (UTC)
Oppose. per Filceolaire: if you want to use WP structure, use directly WP data, if you want to use WD data, use WD structure with appropriated properties. Snipre (talk) 13:57, 17 April 2015 (UTC)
@Filceolaire, TomT0m: Sorry for giving an overly narrow example. Generally, there's no property to say "Item1 is related or useful for Item2". You seem to claim (same as CIDOC CRM) that a general "relatedness" property is not useful. But one does not always know a more specific nature of the relation! Filceolaire, "If they have problems doing this then we need to look at what we need to do to solve those problems": exactly! Look at the next section: I am denied an equally general property "category" bceause "Wikipedia categories are a mess". Yet **there does not at present exist** anything better to catch all terms or concepts related to "food and drink". --Vladimir Alexiev (talk) 07:18, 22 April 2015 (UTC)

Proposed by	Wittylama (talk)

Discussion

Sorry if I've not filled out the template correctly... it's the first time I've tried. This issue came up during the GLAMwiki Hackathon this week where I was being taught how to use Wikidata. I was working on the Léon_Pourtau entry (since it's a biography that I wrote on en.wp recently it was a good one to practice with) and even as a group none of us could come up with a "correct" way of inputting the "place of death" field. "Atlantic ocean" is too vague, and "sable island" is incorrect. It was suggested I come here to propose the option I thought of during the event to see what others thought of it. Wittylama (talk) 17:55, 20 November 2014 (UTC)

Support. Cool idea. However, given that qualifiers will not be queryable for the foreseeable future, let's avoid making statements that require examining a qualifier to be correct. For example, if a person were born "around" but not actually in Paris, then state something like "Alice place of birth Greater Paris". In other words, since I can't think of a good example of how this property would used to indicate "nearby", "close to" or "in the vicinity of" but not "located in" or "part of", I'd recommend restricting usage of this property to how Wittylama does in the 'Example' field above.

We should also strive for precision where easily possible. E.g., with Léon Pourtau having died in the Atlantic Ocean near the Sable Island, Canada, we can say "place of death North Atlantic", rather than just "Atlantic Ocean". (The "near" qualifier still obviously helps in that case.) These are just nitpicks. A "near" qualifier seems clearly useful. Emw (talk) 14:01, 21 November 2014 (UTC)

Wow, that island really has really caused some damage (http://nswrecks.net/ns-maps&charts/SableIsland-WreckMap-nsmus2.gif). As for the location, I think that an item labelled "offshore of Sable Island" could also be considered. That item could be "part of" Scotian Shelf (Q7435595), and then "part of" North Atlantic (I'm not sure if the label Northern North Atlantic would apply here). So my suggestions is:

Item: Offshore Sable island

Statement: Is near -> Sable Island
Statement 2: Part of -> e.g. North Atlantic

Item: Léon_Pourtau

Statement: Place of death -> Offshore Sable island

This would not require the usage of any qualifiers in my opinion. --Tobias1984 (talk) 18:08, 21 November 2014 (UTC)

Tobias1984, I agree. Wittylama, what do you think? Emw (talk) 13:48, 8 December 2014 (UTC)

Thanks for making such a considered response to my suggestion Tobias1984 & Emw! I agree that this would solve the issue of this specific article, and I defer to you greater wikidata-expertise in the matter. However, I do worry that this solution requires the creation of a new item that feels very... hackish. It seems to be an intellectual workaround to the specific issue, and one that does not scale....I assume that it's not good practice to simply create wikidata Q items every time we want to indicate that something happened near another existing geographically-marked Q item. For example, I imagine that every article about a shipwreck should ideally have a fact added which indicates where the shipwreck occurred - and in all (?) cases, shipwrecks happen either ON a specific rock, or NEAR a geographical feature. Do we expect to create a Q item for "offshore <harbour>" for every port in the world or "offshore <peninsula>, since every harbour or peninsula in the world has had shipwrecks NEAR it [and this is just limiting myself to discussing shipwrecks...]?

By the way Emw - great presentation! Wittylama (talk) 18:48, 16 December 2014 (UTC)

Wittylama, fair point. (And thanks for the kind words.) I am inclined to simply create this interesting property and hash out best practices on its Talk page, as implementers get a feel for what works for this. Tobias1984, what do you say? Do you support the creation of this property or do you think more discussion would help? Emw (talk) 03:05, 18 December 2014 (UTC)

Support. Comment: We will need to sort out how this property relates to located in or next to body of water (P206) and shares border with (P47) and to borders a region, country, landscape, place proposed above. Should we just make located in or next to body of water (P206) into a more general "adjacent to" property so we don't need these two new properties? Filceolaire (talk) 16:57, 20 March 2015 (UTC)
Oppose Sorry, but "near" is too subjective (Birmingham airport is "near" my house, when I'm travelling, but the shop there is far away when I'm buying a newspaper).

For cases where there is value to referring to the environs of a location, such as the 'waters around Sable Island' or 'environs of Paris', and that can be defined, create a item for the environs and define its scope within that item, then link that item as the location of your original item: Léon Pourtau (Q3271273) => place of death (P20) => 'waters around Sable Island'.

I'm not sure that we can calculate one number of income tax rate for entities for each country. Most of countries does not have a flat rate for such a tax. Moreover, in some countries income tax is not applicable, or could be optional (VAT or turnover tax could be used instead of income tax, for example). Also, the property name sounds with disambiguation (there are many types of taxes, also for individuals, not only for entities), Bezik (talk) 16:41, 19 August 2014 (UTC)
Oppose In most countries there is not just one tax rate. Tax rates can be flat, progressive, regressive and an entity may have to pay taxes on income, assets, interest and so one...

Perhaps "amended by" with a point in time (P585) qualifier would be better. Actually, if the amendment has a separate item, point in time (P585) might not even be necessary, minimizing the amount of redundant statements needed. --Yair rand (talk) 20:12, 4 February 2014 (UTC)

Discussion

Motivation:

Proposed by: Popcorndude (talk)

As discussed here, this property would allow us to link cabinets with the corresponding head of government. The office in question should probably be included with P794 (P794).

Further examples:

28th Canadian Ministry (Q220542) => corresponding incumbent => Stephen Harper (Q206) => P794 (P794) => Prime Minister of Canada (Q839078)
Roberts Court (Q7351999) => corresponding incumbent => John Roberts (Q11153) => P794 (P794) => Chief Justice of the United States (Q11147)
Victorian era (Q182688) => corresponding incumbent => Victoria (Q9439) => P794 (P794) => monarch of the United Kingdom (Q9134365)

Support per linked discussion. We needed a way to link items like "presidency of Jon Doe" and "papacy of Jon Doe" to their titular incumbents. --Arctic.gnome (talk) 14:08, 16 April 2015 (UTC)

@Laddo, Arctic.gnome, Popcorndude: Hi folks, a question about one item cited as example : in 28th Canadian Ministry (Q220542) , why is there a

⟨ 28th Canadian Ministry (Q220542)  

 ⟩ instance of (P31) ⟨ cabinet (Q640506)  

 ⟩
of (P642) ⟨ Cabinet of canada ⟩

???? This seems overly complex compared to

⟨ 28th Canadian Ministry (Q220542)  

 ⟩ instance of (P31) ⟨ Cabinet of canada ⟩

with

⟨ Cabinet of canada ⟩ subclass of (P279) ⟨ Cabinet ⟩

. Let's try to keep it simple. If you want all cabinet instances Wikidata Query works without any wualifier with this modeling. Not to mention qualifiers are not available at this time. I don't understand this modeling, this is complex with no value added, the qualifier is not necessary and I keep the same number of items ... TomT0m ^(talk) 18:33, 16 April 2015 (UTC)

I have no idea, but I have corrected it to what you suggested. Popcorndude (talk) 19:31, 16 April 2015 (UTC)

@Popcorndude: Ok, so other question, isn't that information redundant ? I mean, if we knew, for an historical area, the kingdom(s) or other country involved, we already have somewhere else in the database the header of that contry. Which means that with arbitrary access, it's just necessary to modify the infobox with a little bit of lua code or access some query data to retrieve King Victoria automatically. So it's not really necessary to have this property, eventually, just code the lua infobox and we will show this without filling anything with this property. TomT0m ^(talk) 19:42, 16 April 2015 (UTC)

Items like Roberts Court (Q7351999) and presidency of Barack Obama (Q1379733) are entirely defined by their incumbents; they're kind of meaningless without reference to the person. I guess you could figure out the incumbents by cross-referencing it with other pages, but isn't that true of lots of useful properties? --Arctic.gnome (talk) 21:16, 16 April 2015 (UTC)

Comment head of government (P6) could probably be generated from position held (P39), but it's a separate property. Popcorndude (talk) 21:52, 16 April 2015 (UTC)
