ContentsEvolution of the community communications roles for Wikidata[ edit ]

Hello all,

For the past four years, I’ve been working in the software department at Wikimedia Germany, taking care of the communication between the Wikidata development team and the community, announcing new features, collecting bug reports and feature requests from you. On top of that, I’ve been coordinating various projects, bringing the WikidataCon to life, coordinating the Wikidata decentralized birthday , creating a prototype for Wikidata Train the Trainers , and taking care of various onsite or online workshops, meetups and other events.

Over the past years, with the Wikidata community growing, the development team growing as well, more and more events happening, and the ecosystem of Wikibase users forming a distinct group with different needs, it became pretty clear that one person was not enough to keep track of everything and provide the best support for the Wikidata editors. That’s the reason why, earlier this year, we had the pleasure to announce the arrival of a new colleague who you already know from being an active Wikidata editor, Mohammed Sadat (WMDE) .

We already started a smooth transition of our roles: while Mohammed will become the main person in charge of community communications for the Wikidata and Wikibase communities, I will focus more on organizing Wikidata-related events and supporting community members with their own events and projects. As you may have noticed, Mohammed already took over editing the weekly newsletter , monitoring the social media, and various announcements for Wikidata and Wikibase. As for myself, I will not disappear completely from the Wikidata channels: I will keep supporting Mohammed on community communication, for example with projects like the Wikidata Bridge , in which I’ve been involved since the start.

During this transition phase, we will review and improve our existing communication processes, and you can for example give feedback on the experience you had while reporting bugs or feature requests . Feel free to reach out to Mohammed if you have any questions regarding Wikidata’s development roadmap .

I’m looking forward to continuing working with you on various projects: feel free to contact me if you want to discuss Wikidata-related events, training, online events, or any other ideas you have in mind to gather the Wikidata community and onboard new editors.

Cheers, Lea Lacroix (WMDE) ( talk ) 08:08, 11 September 2020 (UTC)

@ Lea Lacroix (WMDE) : thanks for the update and great to see you are still onboard! − Pintoch ( talk ) 08:30, 11 September 2020 (UTC)@ Lea Lacroix (WMDE) : Thanks for all your hard work, I was wondering what you'd be doing now that Mohammed is on board, glad to see what your plans are, keep up the great work! ArthurPSmith ( talk ) 17:26, 11 September 2020 (UTC)@ Lea Lacroix (WMDE) : (and @ Mohammed Sadat (WMDE) :) I have a question regarding Wikidata Bridge , are you going to adapt it to be used also in Wikisource? I have seen that users are trying to connect Wikidata with book templates, however it seems that the Bridge could work better in that context. What do you think?-- MathTexLearner ( talk ) 20:43, 11 September 2020 (UTC)A suggestion for this years birthparty (as it can't really happen in person): how about handing out 1000 EUR to each of the 100 most active Wikidata contributors and/or ask them to vote which development to assign it to? --- Jura 11:38, 12 September 2020 (UTC)@ MathTexLearner : Thanks for your question. Theoretically, the Bridge is a feature that can be used on any wiki that is connected to Wikidata. So in the future, it could very well be used on Wikisource. However, I don't see that happening any time soon: the Bridge is at its very first steps (first version is currently deployed on one Wikipedia and supports one data type), so there will be quite a lot of development, time and community feedback before it reaches a point where it can be deployed on other wikis.@ Jura1 : The idea of asking the Wikidata community about what their priorities would be for the roadmap is definitely interesting. However, I don't think that it should go with money attribution. Also, in the development world, 1000€ is basically nothing. As one can see for example in the project grants related to software, the costs range is much bigger. And why should it be the top 100 editors, aren't the newcomers and casual editors interested in selecting projects that could make their life easier as well? Finally, I think throwing money to people to develop features is not the right way to go. Features should be developed in a consistent way, attached to the existing codebase and making sure that the existing development team has the resources to maintain them in the future. It is less a matter of money than priorities and sustainability. And BTW, the birthday celebrations are definitely happening - plenty of cool events taking place online and offline. Lea Lacroix (WMDE) ( talk ) 07:01, 14 September 2020 (UTC) Supposedly the 100 people don't all have different view ..It seems to me the last birthday celebrations were mainly attended by some of the 100 most active contributors and did seem to cost 1000 per person. Essentially all money that wasn't spent on development, so we still haven't gotten to the bottom of the Query Server problem .. (after 2 or 3 years?) --- Jura 17:26, 15 September 2020 (UTC)It's quite easy to understand being a part of the community what the developers do. We can look at Phabricator and see what tickets they are working on and when needed give feedback. On the other hand the amount of community tasks that are visible to the community don't seem to be big enough to occupy two people in addition to a project manager. Northcote Parkinson studied how the British Civil Service manages to increases it's headcount while the amount of thing it actually got done shrank. The WMF has a history of engaging in make-work for an increasing number of employees while editorship numbers fell in the early part of the last decade that to me seems like it mirrors what Parkison studied.It seems like Jura1 ( talk contribs logs ) is suggesting that a lot of money was spent for the birthday party that could have been spent better on development.When it comes to "community communication" it would be good to have a clearer idea about what tasks are done. I good portion is likely Parkinsonian make-work that wouldn't need to be done. Another portion could be tasks that the community could do and where facilitating the community to do the tasks would be better then doing them with paid labor.When it comes to missing community communication, we have performance issues with the Query Server. It would be good to have a general guide about how data modeling decisions made on Wikidata affect the performance as that allows us to get most out of what the query server can deliever.Earlier this year Mohammed Sadat (WMDE) ( talk contribs logs ) posted two weeks queries that suggested that certain people who aren't slave holders are slave holders. He promized to do everything he could to not do the error again. The suggestion to do through a standard quality assurance process like the 5-Why's to fix whatever went wrong was ignored. That leaves me with the question of whether I should believe that future promises to do things will also be insincere.I also do believe that it's worthwhile to be transparent about the community communication processes to allow for improvement. ChristianKl ❫ 11:14, 16 September 2020 (UTC) @Jura, ChristianKl: I don't want to discuss about WMDE's (or WMF) budget and strategy here. It's much more complex than "throwing more money at deployment" (just like the issues with the Query Service are much more complex than "let's buy more servers") and it's a topic where it is necessary to have the full picture in mind to have constructive discussions. It's not my role to discuss these choices with the community, and I'm sure that people who want to discuss about how money is spent have been following the various discussions and projects around the movement strategy and the Wikidata strategy .About the Query Service, our colleagues from WMF are doing a lot of efforts to communicate about the status of the Wikidata and Commons query service (see emails from Guillaume Lederey on the Wikidata mailing-list). They also stay very accessible per email or during office hours, and they are not hiding anything about the issues and doubts they encounter: so people who are willing to get more technical details about the Query Service can definitely find information.We saw your suggestion about the 5 whys and we decided to not answer that. The apologies have been done, the issue has been discussed internally with our manager, and we will not expose the details of these discussions out here.Providing transparency regarding Wikidata's development does not mean being accountable to the editors for our daily work, neither disclosing precise information about the tasks we do. I don't think knowing exactly what we do of our day is going to support you directly in having a good experience while editing Wikidata. If you disagree with that, and since you seem to think that our work is useless, "Parkinsonian" whatever that means, and easily replaceable, feel free to contact our manager who will be happy to continue this discussion. As for me, you can consider this message as being my last interaction with you two on this topic. Lea Lacroix (WMDE) ( talk ) 13:57, 16 September 2020 (UTC) Please avoid mixing me up with ChristianKl. Is there place in Wikidata strategy where we could have read about the 100* 1000 EUR for the birthday party? --- Jura 07:04, 22 September 2020 (UTC)@ Lea Lacroix (WMDE) : Thanks for all the work you have done in these years! -- Epì dosis 11:22, 16 September 2020 (UTC)Can P31 properties have a preffered rank?[ edit ]

I noticed several cities, notably Cairo (Q85) , Montevideo (Q1335) , Copenhagen (Q1748) and Lima (Q2868) don't show up as an instance of (P31) of city (Q515) . Turns out, are listed as cities, but the capital (Q5119) value has the preffered rank set, so it supersedes all other values. Is this correct? I changed it for other cities, but these are semi-protected.

Svízel přítula ( talk ) 21:01, 15 September 2020 (UTC)

I suppose preferred ranks would be needed if there were instance of (P31) statements that were outdated and no longer valid, but then all the currently valid statements should be preferred. I don't see any reason to give preferred rank in a case like capital vs city. Ghouston ( talk ) 01:52, 16 September 2020 (UTC) An example of outdated-vs.-permanent P31 values is Dadra and Nagar Haveli (Q46107) . But the historical value is not marked as deprecated (nor the current value preferred). — Scs ( talk ) 11:53, 16 September 2020 (UTC) When we use rank, we don't deprecate historical values but generally qualify them with end time (P582) and then set the current value as preferred. There are plenty of cases like Dadra and Nagar Haveli (Q46107) where it would make sense to use ranks but we currently don't as nobody did the task to set the rank. ChristianKl ❫ 12:01, 16 September 2020 (UTC) With Dadra and Nagar Haveli (Q46107) , it may be better split into separate items, given significant changes in status. It also has a dissolved, abolished or demolished (P576) which means that "current value" has no meaning. Ghouston ( talk ) 12:29, 16 September 2020 (UTC)I'd also prefer using the dedicated property capital of (P1376) to indicate that relationship instead of instance of (P31) . Ghouston ( talk ) 01:54, 16 September 2020 (UTC) I agree. The property is better to communicate the information. ChristianKl ❫ 12:01, 16 September 2020 (UTC)As an aside, remember that straight P31 relationships are not generally a reliable way to query for is-a relationships, anyway. For example, Boston (Q100) isn't (directly) a city, either, and the reason has nothing to do with ranks. wdt:P31/wdt:P279* is your friend! — Scs ( talk ) 12:09, 16 September 2020 (UTC) True, but that also won't work here, since capital (Q5119) is not a sublass of city (Q515) . I also query for "is a capital" using capital of (P1376) and "is a location" using coordinate location (P625) , as that's faster. Svízel přítula ( talk ) 15:39, 16 September 2020 (UTC)A big "meh" to P31= city of the United States (Q1093829) and anything like it. Andy Mabbett (Pigsonthewing); Talk to Andy ; Andy's edits 21:42, 20 September 2020 (UTC) Unfortunately there are many like this, including the beginnings of a hierarchy of them via city of Oregon (Q63440326) , city in the state of New York (Q15063611) etc. -- Oravrattas ( talk ) 05:49, 21 September 2020 (UTC) Lovely. Let's recreate the entire set of Wikimedia project category trees, why not? Andy Mabbett (Pigsonthewing); Talk to Andy ; Andy's edits 19:21, 26 September 2020 (UTC) rail motor coach (Q752392) and railcar (Q7132141) [ edit ]

I think they are the duplicates of each other and should be combined. Smiley.toerist ( talk ) 08:37, 16 September 2020 (UTC)

Given that EnWiki has separate pages for each of them, they aren't doublicates for Wikidata. It might be necessary to clarify either item to make it more clear how they differ but they aren't duplicates. ChristianKl ❫ 09:25, 16 September 2020 (UTC)The main difference seem to be that a motorcoach can pull other trailers and can function as a locomotive. Railcars are lighter. The definitions are not air-tight, as some railcars can pull exceptionaly pul a trailer. The distinction between a articulated vehicle and a multiple unit is also not clear. Smiley.toerist ( talk ) 11:55, 16 September 2020 (UTC)I think a lot of 'railcars' are wrongly classified as 'motor coaches'. Motor coaches are used in combination of several other rail vehicles, not singly. Railcars are easily identifiable by having a driving post at both ends of the vehicle, as they have to be driven in both directions as a single car. They can often be coupled to other 'railcars' to from a train or pull a trailer. Mostly one, as railcars are motorised for only a single vehicle. Only vehicles powered by internal combustion engins can be considered as a railcar. A counter example is File:BT BDe 3-4 43.jpg where motor coach is used as a locomotive. Diesel powered multiple units quite often have a 'motor coach' for the engine power. ( File:01.08.92 Liefkenshoek 4006 (5804300936).jpg ). These motor coaches never have a separate article, but are part of an multiple unit train type. Smiley.toerist ( talk ) 09:49, 17 September 2020 (UTC)PS:The example used in eo:Relaŭto is articulated and should be considered as multiple unit, not as a railcar. As I dont know the language I cannot check if the text is correct. Smiley.toerist ( talk ) 09:58, 17 September 2020 (UTC)I have now transferred from 'motor coaches' to 'railcars' for the the following languages: cs, da and pt. De definitions vary widely. 'motor coaches' ave mostly electric examples. in many languages there is no distinction between electric or combustion engine energie source. Smiley.toerist ( talk ) 11:32, 17 September 2020 (UTC) It would be helpful if non-specialists could understand from both statements on the items and (English) descriptions the difference between the two items. --- Jura 09:34, 20 September 2020 (UTC)Model item for criminals[ edit ]

What do you others think about this modeling? Too many qualifiers in 'significant events'? Paul Moore (Q99343501) -- Trade ( talk ) 07:37, 17 September 2020 (UTC)

I see no reason to have a significant event for the conviction as that's already covered by convicted of (P1399) . place of detention (P2632) is currently not used and if it would be used with start time (P580) you wouldn't need imprisonment as significant event. charge (P1595) is currently not used.Using occupation (P106) for something that a person did once in their lives feels wrong. The person likely has an occupation in which he spend much more time then in either of the three currently listed. ChristianKl ❫ 08:26, 17 September 2020 (UTC) So, when am i allowed to use murderer as an occupation?-- Trade ( talk ) 14:02, 17 September 2020 (UTC) Thats not an occupation, is it? I mean an occupation is something that is giving an income. If you are a hired killer, thats an occupation.-- So9q ( talk ) 10:26, 24 September 2020 (UTC) We don't know what counts as an occupation, see Wikidata:Project_chat/Archive/2020/01#Occupation=photographer . I don't think being paid is a necessary requirement, not everybody is part of a market economy. Ghouston ( talk ) 10:53, 24 September 2020 (UTC)Not to mention Bill Gates (Q5284) with occupation philanthropist (Q12362622) ... not a big source of income, I'd say. Ghouston ( talk ) 10:59, 24 September 2020 (UTC) anecdote (Q193206) and Russian jokes (Q2374151) [ edit ]

There is a bit of a mess here. Most of wikis currently located at the child ( Russian jokes (Q2374151) ) seem to belong to the parent ( anecdote (Q193206) ), property topic's main category (P910) clashes, etc. Please help to assign inter-wikis correctly. Cheers, Henry Merrivale ( talk ) 10:46, 17 September 2020 (UTC).

It seems these wiki articles actually form quite a spectrum of descriptions: short accounts that are not at all necessarily humorous (en:Anecdote, simple:Anecdote, it:Aneddoto); short, usually humorous story (fi:Anekdootti, de:Anekdote); short, (necessarily) humorous story, but without any national specifics (ru:Анекдот, be_x_old:Анэкдот, be:Анекдот, sk:Anekdota_(zábavný_príbeh), bg:Анекдот, mk:Анегдота); short, humorous story, just like the previous one, but in the context of Russian and Soviet culture (en:Russian_jokes, tl:Mga_birong_Ruso). This probably needs more wikidata items, but I'm not sure how much. -- MetaWat ( talk ) 19:31, 17 September 2020 (UTC) Also, for an example of a ruwiki article similar in nature to en:Russian_jokes, see East Germany jokes (Q5328438) . -- MetaWat ( talk ) 23:58, 17 September 2020 (UTC)Thanks, MetaWat for the analysis. I participated in these items but now I see that the situation is even more complex. I have no will here to separate into more items but it would probably solve the issue. -- Infovarius ( talk ) 15:39, 21 September 2020 (UTC)Possible duplicated information[ edit ]

See Q3132861#P1343 and Q3132861#P4823 . Now we have three ways to link an item to an ANB article (using described by source (P1343) = American National Biography (Q465854) ; using American National Biography ID (P4823) ; creating an item for the specific ANB article). In my opinion the second is useful (convienent for query); the third can provide some meta-informtion about ANB articles, but what is the proper way to link such items from the subject item. @ Gamaliel :.-- GZWDer ( talk ) 04:04, 18 September 2020 (UTC)

Yes, I think when we have an identifier statement like American National Biography ID (P4823) , then described by source (P1343) is redundant and should be omitted -- keep described by source (P1343) for sources without an identifier property. The statement is subject of (P805) qualifier on the American National Biography ID (P4823) statement for the item specifically representing this article is a nice touch, and IMO a good way to record this linkage. Jheald ( talk ) 20:28, 18 September 2020 (UTC) I agree, generally when we add a new identifier we delete the now redundant way of linking. We remove "described at url" and "described by source". -- RAN ( talk ) 21:35, 19 September 2020 (UTC) I perfectly agree, in such cases described by source (P1343) is redundant and should be removed; some time ago I saw a different view here , but I think P1343 is as superfluous with American National Biography ID (P4823) as with Dictionary of Swedish National Biography ID (P3217) . -- Epì dosis 10:24, 26 September 2020 (UTC)Difference between set (Q36161) , group (Q16887380) , class (Q16889133) , and class (Q5127848) [ edit ]

I'm trying to understand the difference between the above three way of classifying collections of things. My current understanding is as follows:

class (Q16889133) are collections of things that meet a certain rule.Groups are like classes except have a more 'concrete' rule (eg. for people they must associate with each other or for objects they must be physically close).Sets are classes that can only contain mathematical objects and unlike the other two cannot change with time. class (Q5127848) are more general classes and encompass class (Q16889133) and set (Q36161) (but not group (Q16887380) for some reason).Members are instance of (P31) class (Q5127848) .Members are instance of (P31) class (Q16889133) .Members are part of (P361) groups.Elements are part of (P361) sets.

However sets are class (Q5127848) , so should part of (P361) be a subproperty of instance of (P31) ? Or should we say elements are instance of (P31) sets? Should groups be instance of (P31) class (Q5127848) ? At the moment metaclass (Q19478619) subclass of (P279) class (Q5127848) of class (Q16889133) . Should it instead be metaclass (Q19478619) subclass of (P279) class (Q16889133) of class (Q5127848) so set (Q36161) can be instance of (P31) metaclass (Q19478619) ? (edited to include class (Q16889133) ) -- Cdo256 ( talk ) 06:26, 18 September 2020 (UTC)

Maybe looking at the (English language) descriptions (in addition to the statements on the these items) can help: set (Q36161) : well-defined mathematical collection of distinct objects group (Q16887380) : summarizes entities with similar characteristics together class (Q5127848) : philosophical term denoting a group of things derived from extensional or intensional definition--- Jura 06:33, 18 September 2020 (UTC)I got confused between class (Q16889133) , and class (Q5127848) , but I meant class (Q16889133) .The en description of class (Q16889133) : collection of items in an ontology sharing common characteristics is very terse and doesn't distinguish itself well from group (Q16887380) : summarizes entities with similar characteristics together.I guess what I really want is examples of: when a class (Q5127848) is not a class (Q16889133) when a group (Q16887380) is not a class (Q16889133) (if ever)when a class (Q16889133) is not a group (Q16887380) -- Cdo256 ( talk ) 06:57, 18 September 2020 (UTC) Cdo256 , these are really good questions; I've been considering some of the same items and how to clarify the distinctions between them. So, what are the differences between set (Q36161) , group (Q16887380) , class (Q16889133) , and class (Q5127848) and when should or shouldn't each be used? (I will also include class (Q217594) in my reponse). Based on the linked Wikipedia page , class (Q16889133) is specifically a class in a "knowledge represenation" (i.e. an ontology). Thus Q16889133 is a good item to use when talking about Wikidata classes. You can be more specific, however, by using Wikidata metaclass (Q19361238) for classes of classes and Wikidata instance class (Q21522908) for classes of instances.The item class (Q5127848) refers to the philosophical concept of a "class," and is broader than class (Q16889133) . A class has to actually be included in an ontology to be an instance of class (Q16889133) (which presumably means its insances have some shared characteristic) but every collection of things is a class (Q5127848) , so the set "{1, apple, every left shoe}" is a class (Q5127848) but not a class (Q5127848) .The Wikidata items class (Q217594) and set (Q36161) are types of mathematical objects that should be used only within the scope of mathematics. There are several formal (not-quite-equivalent) definitions of " class " and " set ," but for the sake of understanding the difference between a set and a class, a "set" is defined such that it generally matches your intuition for a colleciton of items except that that certain collections are prohibited. You cannot, for example, have a set that contains all sets that don't contain themselves (otherwise you break mathematics !). A "class" is then either a set or a collection of sets that is not itself a set. (An example of class that is not a set is the class that contains all sets.) See Wikipedia:Class (set theory) for details.To reverse engineer a definition for group (Q16887380) , I translated all the descriptions to English. A summary of common descriptions are "entities with similar characteristics," "set of things or people," "group of living things," "two or more objects," or "entities with similar characteristics and coexistence." (My favorite Google translation, however, is: "what is and what is what is" ����) My assesment, then, is that a "group" is an exaustive collection of two or more concurrent physical things (real or fictional) that have an mutual association or defining charactersitic. So examples of groups are: The Beatles (Q1299) , the stars in our galaxy, and Bonnie and Clyde (Q219937) . Examples that are not groups are John Lennon (only one item), the set {John Lennon and Paul McCartney} (not exhaustive), the set of real numbers (not physical), presidents of the United States (not concurrent), and the set { New York City (Q60) and Julius Caesar (Q1048) } (no association). So every group is a class (Q16889133) , but not every class (Q16889133) is a group.I'll leave the question of the difference between part of (P361) and instance of (P31) for another time and/or person :)— The-erinaceous-one ( talk ) 10:53, 18 September 2020 (UTC) (please ping me in responses) The-erinaceous-one , thank you for the very detailed response. That's cleared up my main confusion. I'll have to have a think about this for a few days for it to sink in properly. -- Cdo256 ( talk ) 02:52, 19 September 2020 (UTC) Cdo256 , no problem! I appreciated the nudge to start sorting out our various types of collections on Wikidata.My assesment of group (Q16887380) was a bit off, however: it matched the descriptions, but looking at all the direct subgroups [1] , we find that groups also can contain events and abstract objects, and there are subclasses group of 0 (Q39604693) and monad (Q39604065) which have fewer than 2 items by definition. This seem to be the result of inconsisent modeling, however, and I am trying to fix it.In addition to the items mention above, I've discovered that there's also collection (Q28813620) : a set of items held singly, which is not clearly defined at all. So this all goes to say that there's a lot of muddled modeling when it comes to collections on Wikidata. In order to organize all the information about these various types of collections, I've made a page where I'll be trying to sort this all out: User:The-erinaceous-one/types of collections . I would welcome any contributions!— The Erinaceous One ���� 09:50, 19 September 2020 (UTC)More generally, Wikidata doesn't work that well for general abstract concepts with several definitions for the same/similar names. This can be because the Wikipedia articles tend to combine them, because various Wikipedia versions combine them differently or because different Wikidata contributors try to insert these elements in various ways into the P279-tree. It can be solved, but generally requires creating new well-defined and described items and having some sitelinks on items for Wikimedia page relating two or more distinct concepts (Q37152856) . Individual instances are generally better maintained (and easier to maintain). --- Jura 08:45, 19 September 2020 (UTC)--- Jura 08:45, 19 September 2020 (UTC) Yes, it's difficult to create really clear modeling in Wikidata (and probably anywhere), especially when we're dealing with foundational abstract concepts in the ontology. I think we'll be able to sort out the various types of collections, though, in such a way that they are defined clearly and editors understand how to use them. For example, the description for group (Q16887380) , "summarizes entities with similar characteristics together," has never been revised and clearly has room for improvement. — The Erinaceous One ���� 07:35, 21 September 2020 (UTC)There's the nice Q+-template that gives class (Q16889133) : collection of items in an ontology sharing common characteristics / class (Q5127848) : philosophical term denoting a group of things derived from extensional or intensional definition / class (Q16889133) : collection of items in an ontology sharing common characteristics. This discussion would likely be easier to read if it the template would be used more when otherwise it's necessary to click on the item to know which is meant.

If you are trying to create a database outside of Wikidata, this isn't the place to get help. Maybe try stackoverflow.com? If you want to use Wikidata to acheive your goals, then you'll need to provide more details about what you are trying to do, what you have tried, and where you got stuck.

I'm trying to build out a complete reference so that I'll be able to use Wikidata for a Wikipedia application. However, for the author (P50) field, it displays on Wikipedia as "First Last", rather than "Last, First" as Wikipedia style normally dictates. I've filled out the first and last name fields on the author's item, so Wikidata should be able to handle this, but it doesn't seem able to yet. Could this be addressed? {{u| Sdkb }} talk 08:01, 19 September 2020 (UTC)

Using en:Template:Cite Q ? It's using the author (P50) field on the publication (and you'd have to check the template source code to find what it takes from the author item), but it's an issue for that template specifically. There must be lots of such examples throughout Wikipedia. It says on the documentation:

Order of precedence for rendering author names:

stated as (P1932) qualifier on author (P50) author name string (P2093) author (P50) label in English author (P50) label in any other language Ghouston

Ghouston ( talk ) 08:35, 19 September 2020 (UTC)

@ Ghouston : Thanks for the link. I'm not sure how I'd use that template within w:Template:Wikidata , and in any case, it doesn't appear to handle the author name properly itself.If you all want some incentive to fix this, the page where I'm trying to do this is on the path to soon becoming a featured list . The Wikidata links are much less likely to survive the upcoming FLC review if en-WP editors can point to a way in which the Wikidata-derived citations are inferior than if they display identically. So this issue will potentially determine whether or not we're able to get some featured-level Wikidata-integrated content on en-WP. {{u| Sdkb }}  talk 03:24, 20 September 2020 (UTC) I don't think that using en:Template:Wikidata to generate text, as on that page, is permitted in the English Wikipedia in any case ( en:Wikipedia:Wikidata#Appropriate_usage_in_articles ). At best, Wikidata can supply data for infoboxes, and references e.g., via en:Template:Cite Q . I guess the names in a citation should be taken as written in the work itself, instead of generated from everything that we may know about the author. But trying to convert a value from stated as (P1932) automatically may be complex and error-prone. The text I quoted from Cite Q above is actually from the "issues" section on the template, so may not be the way it's currently done. Another listed issue is "Author name should display as "Last, First Middle" to match Wikipedia house style". The template authors have probably realised that it's difficult. Ghouston ( talk ) 04:17, 20 September 2020 (UTC) @ Ghouston : I just added that last listed issue earlier today haha; there wasn't anything previously. I'm not sure who to ping who might be interested in working on this, but there are probably quite a few instances of w:Template:Wikidata that include a reference with an author name (and if there aren't currently, we hope there ultimately will be), so fixing this will have a widespread impact. {{u| Sdkb }}  talk 06:53, 20 September 2020 (UTC) Well, I think the only way it could be done reliably is by specifying the names manually in the right order, either in a new qualifier for the publication items in Wikidata, or in Wikipedia as a parameter to the template. Ghouston ( talk ) 08:03, 20 September 2020 (UTC) en:Template:Wikidata uses en:Module:Cite Q to display some references (those with the right properties). It may also compile reference statements in a best-effort way (those which have divergent properties). In that case, it simply takes the label from the author's Wikidata item. To convert that into "Last, First" is tricky indeed, as there's not one rule which can be applied to all names (think of first names that consist of two detached parts and last names consisting of multiple parts). It would help if all author items have a given name (P735) and a family name (P734) statement, but that's not the case (also because not all given and family names have a Wikidata item). And if you would want to use those statements and retrieve them, then that means that you would first need to load the author's Wikidata item, which is an expensive operation. Maybe an option to give a Wikidata item a person's name (with one field for the given name and one for the family name) instead of a single label would be a nice feature. But for now, some best-effort approach may be thought of perhaps. Also pinging @ Mike Peel as he's planning to improve en:Module:Cite Q soon. Thayts ( talk ) 17:56, 20 September 2020 (UTC) Using given name (P735) and family name (P734) wouldn't be a reliable way to reproduce an author's name, as written on a particular text. It may not even be in the same script, or if you use the English label instead of the native version, it may not be the same transliteration. If Jane Brown writes an article, and puts her name on it like that, would you really want to reference it as "Brown, Jane Elizabeth de Pfeffel", just because the middle names are available in Wikidata? What if she changed her surname in the meantime? Ghouston ( talk ) 23:03, 20 September 2020 (UTC)Loading the author's Wikidata item would be a cost that would probably be paid anyway, to allow linking to the author's Wikipedia page if they have one. Ghouston ( talk ) 23:09, 20 September 2020 (UTC) That does not require the whole item to be loaded, so that's less expensive. Regarding author name changes etc., maybe we would need to have separate string-based properties for author names, but that would be a maintenance hell. Thayts ( talk ) 09:00, 21 September 2020 (UTC) They would only have to be set on items that are used as references in Wikipedia, and only when somebody cares enough to want perfect formatting. Once set they won't need to change, so no maintenance is needed. Ghouston ( talk ) 09:46, 21 September 2020 (UTC) It'd still be a violation of w:Don't repeat yourself , create busywork for perfectionists, etc. So generally a bad idea. {{u| Sdkb }}  talk 23:55, 21 September 2020 (UTC)Although, I suppose it's not just Wikipedia (in its various languages with different requirements), but anybody who wants to generate reference lists from Wikidata would have the same problem. Ghouston ( talk ) 09:52, 21 September 2020 (UTC)Maybe there's a way that name formats could be put on a person item, to avoid repetition. We could have a new property "name style" which would have a multilingual string similar to stated as (P1932) , and matching the way that the name is written in works (books, films, whatever). E.g., for Iain Banks (Q312579) the first such statement could be "Iain Banks" and second "Iain M. Banks". This property would have qualifiers like "name format last first" which would take a monolingual string value, in this case "Banks, IanIain" (English). The algorithm for formatting an author name on a given publication would be a) for each name associated with a work, get a name style, from a "name style" qualifier if set, otherwise from stated as (P1932) (if neither is set, use the label of the author item following a language fallback list.) b) find a matching "name style" statement on the author item, pick the preferred format qualifier, e.g., "name format last first" or "name format last initials", and select the preferred language by following a language fallback list. So then you can get a formatted name like "Banks, Iain M." from Consider Phlebas (Q261728) or "Liu, Cixin" from The Three-Body Problem (Q607112) , or something different if you were prioritizing Chinese. Ghouston ( talk ) 00:50, 22 September 2020 (UTC) @ Ghouston : May I hope that you did not mean to suggest that we would translate the Scottish Iain to Ian for an English-language label, and that was just a typo? - Jmabel ( talk ) 01:51, 22 September 2020 (UTC) Oh no, I started out with "Ian" throughout and then noticed the mistake and fixed most of them. Putting a language label on a name, especially when it's "en" used as a default for all kinds of names, will always look wrong though. But I wouldn't like it to be like labels, where there are dozens of identical labels for the various languages using Latin-based scripts. Ghouston ( talk ) 04:03, 22 September 2020 (UTC) But still, how would you handle changed names and maybe pseudonyms for different works by the same person? Thayts ( talk ) 07:51, 22 September 2020 (UTC) On the item for the person, there'd be a separate "name style" statement for each name variant. Perhaps the details could be improved somehow, but basically there's a collection of formatted names on the person's item, and a method of selecting the one required. Ghouston ( talk ) 08:39, 22 September 2020 (UTC)Looking at Douglas Adams (Q42) , we have "Douglas" and "Noel" as given names, with series ordinal (P1545) as qualifiers and "Douglas" given preferred rank, and of course "Adams" as family name. Should we set a standard that the preferred rank would mean translate that to "Adams, Douglas" rather than "Adams, Douglas Noel"? With that, I think we'd have all the needed information already in the item.Does anyone know how the "Last, First" format typically works for countries in which the last name is normally listed first? I.e. is it "Mao, Zedong" or just "Mao Zedong"? If it's the latter, we might have an issue. But that is I think a level of detail that even Wikipedia citations aren't yet built to handle; if you do {{cite book|last1=Mao|first1=Zedong}}, it'll spit out "Mao, Zedong". That's the main edge case I can think of. I also recently encountered an instance at Frank Parkhurst Brackett where I got a value type constraint error for listing "Parkhurst" as the second given name (what I think we're supposed to do for middle names) because it's classified as a family name, but that's tangential. {{u| Sdkb }}  talk 17:05, 22 September 2020 (UTC) I don't think this is a problem. But for non-Latin names, one common issue is that there could be multiple Latin transliterations for a name, and the person may use a specific transliteration for their name. For instance, the family name of Steven Chu (Q172466) is Zhu (Q13391907) , which is most commonly transliterated as "Zhu" nowadays, but he uses "Chu" instead. -- Stevenliuyi ( talk ) 20:40, 22 September 2020 (UTC) The preferred rank shouldn't be used like that, because "Noel" is just as valid as "Douglas". Besides that, is also offers no help if you want to match the specific form of the name on a particular work, e.g., "Iain M. Banks", when M. is a made-up initial used on only certain works, or works by "Richard Bachmann" ( Q39829 , so do you cite them with the pseudonym or the real name, I have no idea), or for people who change their names and if you want to cite the earlier works with the original name. I'm assuming you want to cite works using the name as given on that work, although I don't know for sure that that's the preferred practice. Ghouston ( talk ) 22:33, 22 September 2020 (UTC) George Eliot (Q131333) is another that comes to mind, should her works be cited as "Evans, Mary"? Ghouston ( talk ) 22:38, 22 September 2020 (UTC)"Douglas", "Noel" ought to be handled as a sequence, not as one being more preferred. - Jmabel ( talk ) 22:40, 22 September 2020 (UTC) Yes, they already have series ordinal (P1545) qualifiers, and that's enough. Ghouston ( talk ) 22:57, 22 September 2020 (UTC)Steven Chu was born in the United States, and maybe his birth certificate reads "Chu". Perhaps family name (P734) should be set to a surname item for Chu in the Latin alphabet, which doesn't seem to exist at present. Ghouston ( talk ) 23:13, 22 September 2020 (UTC) It would be harder to decide which family name to use for those who have more mixed background, such as Charles K. Kao (Q16389) (whose family name is Gao (Q713706) ). I guess maybe we could set multiple family name (P734) and use qualifiers to differentiate? -- Stevenliuyi ( talk ) 00:48, 23 September 2020 (UTC) Yes, multiple versions of the surname are probably needed in some cases, such as when an author has had works published in multiple scripts. Ghouston ( talk ) 01:17, 23 September 2020 (UTC)I'm surprised nobody here has suggested that the enwiki "Last, First" standard should be abandoned. Names are far harder than any normal person assumes - see this page of falsehoods . The only reliable programmatic approach to handling a name is to spit it out exactly as it was originally provided. On works that means use author name string (P2093) or the stated as (P1932) qualifier on author (P50) and hope that whatever process got those values into Wikidata didn't already munge the names (which sadly often happens). ArthurPSmith ( talk ) 13:27, 24 September 2020 (UTC) @ ArthurPSmith : Wow, that essay is a humbling read for anyone who, like me (and I assume most of us here), likes to fit things neatly into boxes. False assumption 18 is speaking directly to us: People’s names have an order to them. Picking any ordering scheme will automatically result in consistent ordering among all systems, as long as both use the same ordering scheme for the same name. Number 30 is also relevant: There exists an algorithm which transforms names and can be reversed losslessly. (Yes, yes, you can do it if your algorithm returns the input. You get a gold star.) It's a reason to be very glad we use Q identifiers, where the only assumption is one person per person.Regarding the circumstances here, w:Template:Wikidata is still obviously in beta, so our goal shouldn't be to get something that'll work perfectly in every possible situation, but rather something good enough that it's capable of spitting out "Seery, John Evan" when presented with John Evan Seery (Q97940622) (possibly with a parameter flipping the switch), and future-proof enough that it can be improved over time. I could always replace author (P50) with author name string (P2093) at the reference being drawn from at Pomona College (Q7227384) , but that's not future-proof, since it'd disconnect the reference from the author's item. {{u| Sdkb }}  talk 22:04, 24 September 2020 (UTC) Thanks for posting the "Falsehoods Programmers Believe About Names" link, it's a classic. It seems that this discussion is still at the stage that some people still think that given name (P735) and family name (P734) are sufficient. The suggested alternative is to declare that producing references, or reference lists, with names formatted to a particular Wikipedia or academic standard is too hard, and we don't even try. The alternative that I proposed above was to allow names, formatted manually into different styles, to be stored in the author's item and selected as required. But that requires a whole new mechanism. Ghouston ( talk ) 22:37, 24 September 2020 (UTC)Importing a template[ edit ]

Hello,

I want to get an Overview about the next events related to Wikidata. The Wikidata event site shows as far as I think not all events. In German Wikipedia there are for special events or for regular events pages with information about how it is possible to attend and what the event is about. That other people can find the event there is a calendar and for the calendar there is a template.

Making IIIF manifests (P6108) link to something viewable[ edit ]

There was chat today in the zoom call about IIIF and Commons (cf some background and notes at Commons VP ), that it would be nice if IIIF manifest (P6108) actually linked to an app displaying the image (with its metadata), rather than to the raw JSON of the manifest.

i.e. it would be nice if going to Q21627180#P6108 , clicking on the blue link took you to eg

https://mirador.toolforge.org/?manifest=https://damsssl.llgc.org.uk/iiif/2.0/1130163/manifest.json

displaying the image, with metadata in the manifest available under the (i) button at the top right, rather than the raw JSON of

https://damsssl.llgc.org.uk/iiif/2.0/1130163/manifest.json

even though the latter would still be the value of the property, returned by SPARQL etc.

I was about to simply add a formatter URL (P1630) statement for the IIIF manifest (P6108) property. But I wanted to check: will this break anything, given that the property is already URL-valued?

For instance, should I also set say formatter URI for RDF resource (P1921) = $1 to make sure that RDF applications get the underlying URL, not the viewer URL? Would this sort it out? Would it be enough? Or would some applications and/or queries still get the wrong URL? Jheald ( talk ) 19:48, 21 September 2020 (UTC)

Hmm. Experimenting with the sandbox & sandbox url property, User:Jon Harald Soby has shown that that (probably) doesn't work. As a fallback attempt: can anyone put together a gadget to give a drop-down choice of link destinations, when a property has choices of third-party formatter URL (P3303) defined?

I have a question: how do I model middle name initials for a person? I have David Tabb (Q42887966) which is stated as "David L. Tabb" in ORCID but we dont know what the middle name actually is. Is there a way to model this? Should I use David Tabb (Q42887966) given name (P735) L. (Q19803509) for this? Why wasnt this properly imported from ORCID? -- Hannes Röst ( talk ) 16:05, 23 September 2020 (UTC)

Not sure on how to model it; however many of our researcher items with ORCID links had the names actually imported from elsewhere (PubMed records for example), so the names often differ at least slightly from the name as recorded in ORCID. This isn't always a bad thing - sometimes the name publicly shown in ORCID is just a first name for example. However, I have run into some cases where the link was clearly wrong for some reason, i.e. a completely different name (a coauthor on some article, and the wrong name linked for some reason). ArthurPSmith ( talk ) 17:19, 23 September 2020 (UTC) Hannes Röst On the item for the author, use given name (P735) L. (Q19803509) with series ordinal (P1545) = "2" until the middle name is identified, at which point "L." can be replaced with the actual name. If you want to change the way an author is displayed on a publication item, use the qualifier stated as (P1932) .

Should we create a new property called Military specialty, or some similar name to hold: chaplain, sapper, rifleman, sniper, medic, cook, radioman and other military occupations? Or should we model it as: conflict=World_War_II with subject_has_role=chaplain ? Let me know which one you think would work best. -- RAN ( talk ) 18:13, 23 September 2020 (UTC)

Military occupations are occupations and can be stored in our existing occupation (P106) . If that's not doing the job, can you explain why you think it's not appropriate for what you want to do? ChristianKl ❫ 17:34, 24 September 2020 (UTC)Conflict/subject-has-role won't work as not all military service actually takes place during a conflict.

So we support review score (P444) but it's not widely populated (a few thousand uses). Are there legal/copyright issues that prevent us from mass importing these scores from places like Metacritic (Q150248) and Rotten Tomatoes (Q105584) ? What about aggregations of user reviews available on Goodreads (Q2359213) ? There might be ToS issues with some sources but do we care? Also, how do we deal with the fact that these scores change over time? I don't think we can keep multiple timestamped scores from the same source sanely.

Label/description conflict with a deleted item?[ edit ]Tracked in Phabricator Task T263730

Hello - This is my first import project, and I am not clear on what the spreadsheet should look like to make the data import as easy as possible. My intention is to populate the hardiness zone (P8194) property for US cities. I have a spreadsheet of US cities with their QIDs and labels, and I used the postal code data to create a mapping to USDA Plant Hardiness Zones. I have both the IDs and labels of the Zones in the spreadsheet here https://lite.framacalc.org/9j5d-usda-hardiness-zones-jdc . Here is a sample of the data in the spreadsheet

Unique ID Name zipcode zone zone_qid
http://www.wikidata.org/entity/Q60 New York City 11004 7b Q96279219
http://www.wikidata.org/entity/Q60 New York City 11005 7a Q96578142


I am looking at this step in the import process: https://www.wikidata.org/wiki/Wikidata:Data_Import_Guide/Step_5:_Format_the_data_to_be_imported . Ideally, the 'Unique ID' will be the subject in a statement with the P8194 property and the zone_qid column would be the object. Should I remove the 'zipcode' and 'zone' columns and just rename the 'zone_qid' to 'hardiness zone' and consider it good? Looking at the example spreadsheet in Format the data to be imported, I don't see any property IDs, so should I just use the labels?

In addition, what about adding a postal code qualifier to the statement, since there might be multiple zones associated with a city. But this usage doesn't look in-line with the property constraints on postal code (P281) . Is there something I need to do to make that happen? And how to indicate the qualifier piece in the spreadsheet?

Handling obsolete official website (P856) [ edit ]

Hi. I am trying to tidy up Life&Style (Q1824415) , which an IP user tried to blank in error and merge with an English language edition of the same magazine. As part of the clean up I noticed that the official website (P856) is no longer valid. According to dewiki, the publication ceased in 2012 and the webarchive copy shows the link has been redirecting visitors to an alternate site since at least 2013. The official website (P856) is still trying to redirect visitors but my browser throws up an error and stops me visiting the site (and I am not going to override my browser to see if the code on the current target is safe). However, there is an archive copy of the original site at https://web.archive.org/web/20090305130649/http://www.lifeandstyle-online.de/
What is the best way to handle this? Should I deprecate the old website (which is now redirecting visitors) or perhaps set the end time (P582) as 2012 to match dewiki's claim that it ceased publication? Where should I insert the archive copy? From Hill To Shore ( talk ) 20:06, 25 September 2020 (UTC)

Deprecation isn't recommended for items which were valid at some time but no longer valid, but end date should be set, even if it's just an unknown value. The archive link can be added as a qualifier. If there was a new site, it could have preferred rank. Especially for entities like former publications, it's not unexpected that much of the data will be out-of-date (purely historical). Ghouston ( talk ) 22:07, 25 September 2020 (UTC)correct way to indicate "mayor of [some place]"[ edit ]

working on: Imre Gálffy (Q1031047)

the subject was the mayor of a town; I tried using: position held (P39) mayor (Q30185) of (P642) Miskolc (Q102397)

It throws a "none of constraint" saying that position held cannot be "mayor". How does Wikidata like to represent this kind of information?

Does it want a separate Q entry for every mayorship in the world? (e.g. Mayor of New York City (Q785304) , Mayor of London, Mayor of Podunk, etc.)? If so, is it ok to blithely create that item on the basis of just knowing one of the previous mayors, and not knowing much more about the government of the town?

Thanks - Kenirwin ( talk ) 00:31, 26 September 2020 (UTC)

It is expecting something like mayor of a place in Canada (Q98880424) or mayor of a place in India (Q98848902) . I can't spot one for Hungary though, so that one may need a new item. From Hill To Shore ( talk ) 01:27, 26 September 2020 (UTC)@ Kenirwin : Yes, it's perfectly fine (and indeed recommended) to create a new item for "Mayor of (wherever)" even if you only currently know one officeholder for that, and nothing much else about it other than applies to jurisdiction (P1001) . There are also tools, such as Petscan , that will allow us to, for example, set everyone in Kategória:Miskolc_polgármesterei to have a position held (P39) to such an item once it exists. -- Oravrattas ( talk ) 07:50, 26 September 2020 (UTC) @ Oravrattas : -- thanks for this; I'd not heard of Petscan before, but it seems pretty great. Do you know of any good English-language instructions for doing the kind of thing you're talking about? It's pretty easy to search PetScan, but I'm finding it harder to understand how to use it to add properties/values in WikiData. I read the manual, but I'm finding it tough to understand. I've created mayor of Miskolc (Q99653360) and added it to the one entry, but PetScan finds about a dozen more where it would be relevant. Thanks! - Kenirwin ( talk ) 18:12, 26 September 2020 (UTC) @ Kenirwin : I'm afraid I don't really know if there are any good instructions anywhere: I've mostly figured it out from trial and error, and watching other people use it. The most important (but most easily overlooked) toggle when using it to create claims in Wikidata, is to make sure that "Use wiki: Wikidata" is selected in the "Other sources" tab, before running the "Do it" (yes, it's rather well hidden!) That will then give you a "Command list" box at the top of the result sets, where you can then enter something like position held (P39) : mayor of Miskolc (Q99653360) , to apply that to all (or a selected subset — e.g. removing the "list of mayors of Miskolc" article first) of the results. (You don't need to worry about filtering out ones that might already have it: QuickStatements will skip anything that would create a duplicate statement.) -- Oravrattas ( talk ) 20:33, 26 September 2020 (UTC) @ Oravrattas : -- that's fantastic -- thanks. Yeah, I was never gonna find that... Thanks so much for your help! - Kenirwin ( talk ) 00:29, 27 September 2020 (UTC)Advice on instance of (P31) and subclass of (P279) [ edit ]

Hi. Cdo256 ( talk contribs logs ) has been tidying up on instance of (P31) and subclass of (P279) but has inadvertently been creating constraint violations. I have started a discussion at User talk:Cdo256 but some of the points raised are outside of my experience. I don't have a solid grasp on when instance of (P31) and subclass of (P279) are the correct option, so it may be the user that is correct and it is the property constraint (P2302) that is set wrong. Can someone please offer further advice to the user? Thanks. From Hill To Shore ( talk ) 09:40, 26 September 2020 (UTC)

My feeling is that some of the constraints like the value type constraint (Q21510865) on architectural style (P149) , brand (P1716) , represents (P1268) , and occupation (P106) should be changed to allow both subclasses and instances rather than just instances. Since X instance of (P31) profession (Q28640) implies that X is an indivisible profession with no subclasses however many examples exist where instance of appears to be used the wrong way, for example architect (Q42973) is treated both as an instance and a class (for example urban architect (Q2860261) subclass of (P279) architect (Q42973) , making architect a class), which as Wikidata:WikiProject_Ontology/Problems states, this is an anti-pattern. In the case of occupation (P106) , I think that jobs should prefer to be subclasses rather than instances since a job could be subclassed right down to a specific opening/employee at a specific company. This I think also holds for other properties things like color, shape and texture where it's difficult (or impossible) to define what a specific indivisible shape and color a real world object has. - cdo256 10:41, 26 September 2020 (UTC)String to external-id[ edit ]

Not sure about where I should ask about this. We have Open Food Facts food additive ID (P1820) , Open Food Facts food category ID (P1821) and Open Food Facts ingredient ID (P5930) . Two of them are external-id , one is string datatype. Open Food Facts food additive ID (P1820) should be changed to exernal-id too. Wostr ( talk ) 16:28, 26 September 2020 (UTC)

This request generally go to https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team as it requires the developers to manually update the database. ChristianKl ❫ 19:35, 26 September 2020 (UTC) Thanks. I forgot about this page. Wostr ( talk ) 21:47, 26 September 2020 (UTC)Gitter room[ edit ]

Would anyone be interested in a gitter room for Wikidata (e.g. https://gitter.im/wikimedia/wikidata - currently there are some rooms under https://gitter.im/wikimedia ).

IRC is a bit of a schlep in comparison and there is already a substantial linked data community on gitter with json-ld.org , linkeddata/chat shex and rdf4j to name a few. Iwan.Aucamp ( talk ) 16:34, 26 September 2020 (UTC)

Sitelinks for properties (not just items)[ edit ]

I'm new to Wikidata; please advise me where I can find an existing discussion on this topic if appropriate:

For context, I was looking over the item page for Visual Studio Code (Q19841877) , then followed the subreddit (P3984) identifier property to see what it could do.

I noticed that while there is a Sitelink section for the item, there are no Sitelinks in the properties that I examined.

I understand that the semantics of a property don't, themselves, denote a connection to the reference (Wikipedia), but for many cases, a connection to a reference topic seems immensely helpful.

For this particular property, I happen to know what a subreddit is, and where it comes from. And yes, I can find links to the website at reddit.com. But there are properties, especially identifier properties, that are scoped to a domain (like this one is), and aren't general ontological properties (like "instance of", "inception", "authority" and so on). Some of these domains are unknown to me and, I'm sure, many others.

I thought that for some properties, a Sitelink entry would be appropriate. As an example, for this property, I'd expect to see a Sitelink to en.wikipedia.org/wiki/Reddit, or, at the very least, to the item Reddit (Q1136) . RedCrystal ( talk ) 18:25, 26 September 2020 (UTC)

subreddit (P3984) has both a link to Reddit (Q1136) and subreddit (Q28464970) . The relevant site links are placed on the items. From Hill To Shore ( talk ) 18:32, 26 September 2020 (UTC)It's the nature of sitelinks that one Wikipedia page in a given language has exactly one Wikidata item that links to it. The 1-on-1 relationship is necessary for interwiki links. In this particular case it would make sense to have https://en.wikipedia.org/w/index.php?title=Subreddit&redirect=no as a sitelink for subreddit (Q28464970) that's listed as subject item of this property (P1629) for subreddit (P3984) .In the general case it's a mistake to assume that site-links fully tell you what an item is about. There are plenty of cases where different Wikis have different scopes for articles that are linked to the same Wikidata item. If you want to understand the scope of a property reading the property proposal discussion and the property talk page is where you find the information.

I have been assisting at Wikidata editathons just to discover that, most local languages we were hoping to edit were not supported. This brought the quest for this topic. Since we have Wikidata as our initial point of involving the community, we wish to find out the necessary steps to get these languages on Wikidata.
