I realise that this can be achieved by traversing succeeded by, until the end, but that requires an unknown, and potentially large number of calls, and there is no knowing how branched the tree will be, or if there is a loop somewhere on the way. This property should hold the most relevant value(s), like Benin for Dahomey, or Greater London for County of London. Rotsee (talk) 18:24, 8 April 2014 (UTC)

  Comment I think the need is a real one but the request is not mature enough. Maybe we don't really need to use a new property and deal with this with located in or part of properties with qualifiers to note the validity of the claims, or even just have the geographical locations as coordinates or something and a tool to show this on a map together with nowdays locations. is currently part of seems too dependant of the instant, and can be obsoleted, which imply imo it is not really better than the properties that exists now used in combination. TomT0m (talk) 18:34, 8 April 2014 (UTC)
Many properties are easily obseleted, so while it is a a bit troubling, it wouldn't have to be a showstopper. I'm sure you are right that there might be better ways to address the need, though I'm not sure how. Rotsee (talk)
@Rotsee: I have already started to work with this parameter in this template, and that with parameter located in the administrative territorial entity (P131). Look at Q14934211 where Kinda Municipality (Q515299) have this value with normal rank.
The "prefferred rank" here is used for the county and province the municipality was located in when it existed, and the "normal rank" without "enddate" has the value it is located in now. Using succeeded by am I worried that it would sometimes give a misleading result, since the succession looks very complicated in some cases. (A small municipality is merged into a larger municipality who is later split, take Nyköping as an example.) The consequence is that you cannot use a simple parser to get this value, but it's fully solvable with Lua.
@TomT0m: I do not trust a solution based on coordinates at all today. I have seen such files and they are very simplified, and may give a lot of false positive. -- Lavallen (talk) 07:02, 9 April 2014 (UTC)
@Lavallen: I really like that approach! And I agree that trying to follow succeeded by can be very misleading, or, in some extreme cases, even unsolvable (e.g. loops created when entities are reintroduced). Rotsee (talk) 07:20, 9 April 2014 (UTC)
In "reintroduced entities" have I created separate items for the two entities. Look at Q14943851 and Q1255130. I do not consider them as the same entity, rather as a new entity with the same name as the old one.
And I started to work with this before "ranks" was introduced, so you will find many examples where I haven't finished the work with this parameter yet. -- Lavallen (talk) 07:25, 9 April 2014 (UTC)

Robot and gadget jobsJVbot can already populate from Wikipedia
Proposed byJohn Vandenberg (talk)

English Wikipedia infoboxes use the ISSN based way to link to JSTOR. e.g. w:American Literature (journal) includes JSTOR = 00029831 which is the ISSN for the journal. However we already record ISSNs in ISSN (P236), so it doesnt seem sensible to have another property which is the ISSN that JSTOR recognises, stored in a different encoding. I have randomly reviewed old journals in JSTOR, and it appears they always have an ISSN, so I assume JSTOR or someone else is arranging ISSNs to be issued for these old journals, even for single volume series like this.

However JSTOR also has a textual code for each journal. For the items with a value in the English Wikipedia journal infobox, the JSTOR ISSN value can be transformed into a JSTOR journal code by parsing the JSTOR page. e.g. includes 'londonjmed' in the HTML source in a simple to extract manner - I am happy to do that as a batch job.

  Support. TomT0m (talk) 17:24, 3 March 2014 (UTC)
  Comment John, can you explain to me what the advantage is for having these codes? As you say, the enWP infobox uses the ISSN (minus the dash) to link to JSTOR. I don't see that as a problem, because the reader will not even see this (just a bluelinked "JSTOR" appears in the infobox). Thanks. --Randykitty (talk) 17:31, 20 March 2014 (UTC)
Whether we use the JSTOR ISSN or the JSTOR journal code is of no consequence to Wikipedia - the template will display a link that goes to the same location.
The difference is what we store on Wikidata, and how re-usable / useful is it. If we try to use the JSTOR ISSN, we need to somehow annotate which specific ISSN is the one that works in JSTOR URLs. It cant use any ISSN for the journal - only one works. What might be worth exploring is whether the JSTOR ISSN is the Linking-ISSN (see Property talk:P236#Unique constraint). I see two options for achieving this.
  1. create a new property for the JSTOR ISSN
  2. attach a qualifier to one of the ISSN to mark it as the JSTOR ISSN
IMO, the first of those options is silly - it is a duplication of data. The second option could work.
The advantage of recording the JSTOR journal code is that avoid the above problem of JSTOR ISSNs, and I am willing to bet that the JSTOR journal code is more stable than the JSTOR ISSN and even the Linking-ISSN. John Vandenberg (talk) 01:58, 22 March 2014 (UTC)

This is the Danish authorities simplistic quality indicator, like the (Australia) ARC journal rank. According to this English summary, in Denmark "Publishing in series of level 2 earns more points than publishing in series of level 1." John Vandenberg (talk) 07:32, 6 March 2014 (UTC)

The Norwegian official journal list also uses the same two level ranking[3]. It will be interesting to compare all these rankings using Wikidata. ;-) John Vandenberg (talk) 08:00, 6 March 2014 (UTC)
The Norwegian list includes many journals that have changed levels over the years[4].
I have looked for other Scandinavian countries that might share the same property, but didnt find any. What I did find is European Reference Index for the Humanities (Q15904698) which has gone through two major iterations (2007 and 2011) and looks likely to be gearing up to start the process again. Initially it had categories "A, B, C"[5] but has renamed and reordered them to "NAT (C) INT1 (A), INT2 (B)". The French journal ranking system was similar to ERIH. Interestingly hosting and maintenance of ERIH is in the process this semester of being delegated to the Norwegian organisation w:Norwegian Social Science Data Services that is responsible for their national registry. Searching ERIH also shows journals that have changed category from 2007 to 2011. The ERIH category is provided a few times on Wikipedia articles[6]. John Vandenberg (talk) 14:18, 7 March 2014 (UTC)
  Comment I don't really see the usefulness of including these obscure rankings that are produced by small research communities. Like the French exercise, these things come and then often go again without leaving much trace. --Randykitty (talk) 17:36, 20 March 2014 (UTC)
Randykitty, I dont think size matters! The Scandinavian countries are well known for having high class research - i.e. in the top of the OECD. These indicators are part of the qualitative assessment which feeds government policy and funding decisions which produce high class research.
Secondly, The Norwegian system has been in operation since 2004, and they regularly review and revise the ranking of journals. e.g. Ramus (Q15763952) 's history can be seen here.
Thirdly, as seen over on Wikidata:Property proposal/Authority control, these journal lists are used by Danish and Norwegian Wikipedia, due to their importance for the readership of those Wikipedias. John Vandenberg (talk) 06:00, 6 April 2014 (UTC)

This is more appropriate to the proposed Commonsdata - the wikidata for describing files on Commons.

@Filceolaire: yes this would also be useful on Commons.

    Just a note of the French case, to see if that sounds acceptable:
    • MPs are elected by geographic constituencies, and are usually members of a party.
    • I do not think party affiliation has any official status, but "parliamentary groups" have. Parliamentary groups are MPs that bunch together on political affinity. Normally, all members of the same party are in the same group, but there can be more than one party in one group).
    So would it be ok this way ?

    And a note on New Zealand, which elects MPs under the hybrid MMP system: some MPs (electorate MPs) represent an electorate and other MPs (list MPs) have no electorate, but essentially represent just their party. We have even had a law (since expired) forcing list MPs to resign from parliament if they leave the party they were elected to represent. So here party affiliation can indeed have official status. --Avenue (talk) 02:26, 6 December 2013 (UTC)
    On another discussion about presidents, we concluded it would be beneficial to use items like <president of the united states> instead of <president> (quelified) of <United States>. I guess to be consistent we would have to create one deputee items for parliement posts. TomT0m (talk) 21:22, 5 December 2013 (UTC)
I think it makes sense to create items like "French député of the Fifth Republic", but all members of the parliament have the same status (for France at least), so I do not think it would be necessary to create items for "representative of constituency XX". And given that constituencies can change from one election to the next, that would require many additional items (on the other hand, I guess we will need items for the constituencies ("French constituency XX (period 2012-2017). --Zolo (talk) 21:57, 5 December 2013 (UTC)

@Casper Tinan: France national rugby union team (Q518116) representing French Rugby Federation (Q1479321) seems like a good idea to me, but not Mona Lisa (Q12418) representing "Lisa Gherardini". We can use the word "represent" in some languages here, but that probably does not work for all languages. In any case, the semantics is a bit different (even though there are arguably commonalities as well). Keeping a separate depicts (P180) sounds better to me. --Zolo (talk) 09:24, 1 March 2014 (UTC)
@Zolo: I am not opposed to having separate properties for the different meaning of "represents" : depicts/portrays, symbolizes/embodies, acts on the behalf of. Yet, it would make it difficult to correctly label the different properties in some languages. For instance, the french label for depicts (P180) should also be "représente". (the label "décrit" for this property is totally wrong as it implies a description only with words). Casper Tinan (talk) 11:32, 1 March 2014 (UTC)

Proposed byCasper Tinan (talk)

Motivation : This property will be useful to indicate the first match ever played by a notable team or in which match a sportsperson began his international career. For the latter case, the property would be used as a qualifier. Casper Tinan (talk) 14:33, 15 March 2014 (UTC)

  Oppose the key event significant event (P793) property seems highly usable for this. TomT0m (talk) 19:47, 16 March 2014 (UTC)
@TomT0m: I disagree. If you look at the example mentioned above, the infobox mentions for each national rugby team its first official match, its largest victory and its largest defeat. How could an infobox model choose which claim correspond to each case if you only use the key event property ? Casper Tinan (talk) 21:17, 16 March 2014 (UTC)
@Casper Tinan: the details needs to be figured out, but see Property_talk:P793 : there is several complex example that solves this kind of problems using qualifiers. Plus with claime on the match item itself we can also check things in the model code. We need to think at a higher level than just the property level imho. TomT0m (talk) 21:45, 16 March 2014 (UTC)
@TomT0m: I just had a look at the page you mentioned. The problem is that you almost always need a qualifier and then cannot use the property itself as a qualifier. This would make it impossible to handle basic cases such as

Jonathan Sexton (Q1400144) > member of sports team (P54) > Ireland national rugby union team (Q599903) ("first match" (Pxxxx) > "Ireland vs Fiji, 21 november 2009" Jonathan Sexton (Q1400144) > member of sports team (P54) > British & Irish Lions (Q733600) ("first match" (Pxxxx) > "Australia vs British and Irish Lions, 22 june 2013" Casper Tinan (talk) 21:17, 17 March 2014 (UTC)

@Casper Tinan: Hmm, seems weird, why is the first match so important that it really needs a special treatment ? To retreive the first match it seems simpler to have a match database and to query the set of matches in which the player played for the team and show the first one sorted by date ... TomT0m (talk) 11:50, 18 March 2014 (UTC)
First and last matches are used to populate table such as this one fr:Liste des sélectionnés en équipe de Nouvelle-Zélande de rugby à XV. I hope it would be possible in the future to use wikidata to generate this kind of list.

Data typeItem
ExampleTsavo Man-Eaters (Q2510263) -> Panthera leo (Q140), Bonnie and Clyde (Q219937) -> human (Q5)
Proposed byZolo (talk)

Note: Not sure it has been already proposed are just discussed in other talk pages. Many items are about several things of the same type, like groups of people. Note that using "subclass of" does not seem correct here, are we are more interested in the properties of the group than in the properties of items that make up the group. One way to see this is that "Tsavo Man-Eaters" takes an "s": the item describes a pair of lions taken as a unit, not the common features shared by two lions. For instance, it would not be correct to say "species: Panthera Leo": each individual is a Panthera Leo, but the item as a whole is not.

  • create items about "groups of people", "groups of lions. But for humans that requires a) the creation of many items, and probably b) the creation of a special property linking "group of lion" to "lion". And for the querying software, that requires a) check the value of p279 for all p31 values so that it knows that a group of lion is a subclass of group, b) have a special function telling it how it should behavee when encountering subclasses of group. So I think my proposed solution is all round better than that.
  • Just have "p31: group" and add a qualifier "of humans" etc. That is more or less equivalent to this proposal but using qualifiers for essential information does not seem to be a super idea, as qualifiers are somewhat cumbersome to deal with (wikidataquery and other tools do not currently handle them, apparently it is not foreseen to use them in the near future for in-Wikidata queries etc.).

These two alternative solution also mean that in order to make valid inferences about groups of things, we should have ad hoc function telling what sort of special behavior the querying engine should have when encountering subclasses of group (case 1), or instances of group (case 2). I think having a separate "instance of group of" would make things simpler and much more efficient. --Zolo (talk) 08:15, 25 January 2014 (UTC)

I would prefer having two statements ("p31:human" and "p31:group") and then qualify "instance of" with quantity (P1114) when the size of the group is known.--Micru (talk) 13:00, 22 March 2014 (UTC)
Does not make really sense, being and instance of human meaning is beeing a human beeing. A group is not a human beeing. TomT0m (talk) 13:30, 22 March 2014 (UTC)
@Zolo: I guess we can do the same using
< group item > instance of (P31)   < set (Q1514741)     >
< group item > has part (P527)   < elements type >
TomT0m (talk) 13:30, 22 March 2014 (UTC)
Also I prefer not to use a double instance of P31. I like the solution proposed by TomT0m. --Paperoastro (talk) 14:05, 22 March 2014 (UTC)
@TomT0m, Paperoastro:. Something like that could work but the current usage of "composed of" seems to be enumerating individual elements (composed of: first lion, second lion) rather than indicating the type of the elements (composed of: lion). And in a way, that is more powerful this way, as it allows to use "composed of" for heterogeous groups. --Zolo (talk) 08:17, 23 March 2014 (UTC)
Good point, the composed of description in basic membership properties help page said its usage was disambiguated by wether or not we apply it to a class item or an instance item. I used composed of when I created items untitled group of superheros, for example, this worked fine for me. TomT0m (talk) 11:52, 23 March 2014 (UTC)
you are right, Zolo: P527 is used also to list the element of multiple star system, as Alpha Centauri (Q12176). --Paperoastro (talk) 19:13, 24 March 2014 (UTC)
@Paperoastro:, but
< star system > has part (P527)   < stard >
is also valid :). TomT0m (talk) 19:22, 24 March 2014 (UTC)

  Comment Hi Nico, if you define the infobox artwork parameter "year" as "artwork completed" what's with "artwork started"? Wikidata:Books task force is using inception (P571) for the time a work has been created. This can be used for artworks as well. There is also point in time (P585) as an alternative. BTW: What I really miss is an origin property for artists (= painters etc., not musicians). creator (P170) was meant for this task but unfortunately it is now used as a placeholder for every kind of "creator" making no difference between software, television series, and paintings. --Kolja21 (talk) 21:03, 14 February 2014 (UTC)
  Oppose @Nicholas1981: isn't significant event (P793) for for miscellaneous events like this? @Kolja21: that is how properties are meant to work on Wikidata, as genarally applicable to the data. Filceolaire (talk) 05:08, 25 February 2014 (UTC)
@Filceolaire: 1) "creator": the properties should be generally held yes, but not ambiguous. We have author (P50), editor (P98), developer (P178), designed by (P287), programmer (P943) etc., but no property for artists (= painter). 2) I'm, like you, not convinced of "completed" but imho we need for performing arts and broadcasting "first performance" (see below). --Kolja21 (talk) 06:03, 25 February 2014 (UTC)

Hi Randykitty, good to see you getting involved here in property development ;-) All Wikidata claims should not need updating. They should be sufficiently qualified claims. See for example the impact factor on Nature (Q180445). This data would be a record of a very large and ground breaking cross-discipline exercise of journal ranking. Academics outside of Australia probably have little interest in this, however research evaluation/bean-counters around the world refer to it, both because the data is very useful, and because the data contains some significant problems. This ranking is accused of being responsible for several Australian journals shutting down because they were a 'C' and universities instructed staff to not publish in them, causing much uproar. Universities in Australia still refer to it, and have typically created their own internal journal rankings which are derivations of it with only minor differences to correct the 'errors' as they perceive them. In ERA, impact factor was not relevant. In ERA 2012, for the sciences, citation count and journal ranking were the primary drivers in the assessment. John Vandenberg (talk) 23:19, 21 March 2014 (UTC)

While many indexes provide unique identifiers for the periodicals they include (i.e. act as authority control, such as Scopus Source ID (P1156)), some indexes do not (especially older print only indexes, which tend to be very authoritative), and it will be a lot of work to define properties for each index. 'indexed in' allows data to be input for indexes which dont have unique identifiers (yet), and provides a simple way to access this information for all indexes (rather than testing the existence of each property). Indexes usually have only partial coverage. An 'indexed in' property could have qualifiers for coverage, such as start-end dates, ranges, etc, to better describe whether the indexing and provide a way to determine whether a journal article is indexed by the bibliographic index. When coverage data is populated, it would be possible to answer questions like 'Does Scopus (Q371467) have better coverage of list of sociology journals (Q2731858) than Academic Search (Q1273969).

  Support. I'll ping Dominic. Emw (talk) 04:11, 3 January 2014 (UTC)

Hi all. Thanks, Eric; sorry I didn't get your ping, John. I don't log into Wikidata enough. I like the idea of adding support for NARA, but we might need to think a bit before implementing it. First is that NARA's "ARC" catalog is no longer supported. It is only maintained right now as a legacy for old incoming links. So, for example, the given link should actually be "". This is the same authority record with the same IDs, just in an improved interface. I have changed all the URLs in English Wikipedia and Commons templates, but obviously some old links persist. The second issue is that there are several different URL structures within the NARA authority file for the type of authority. The URL above is only for person authority records, and there are different URLs (and sets of IDs) if it is an organization, geographical, subject, or specific records type authority record.

I would have to check and make sure I haven't forgotten any more types. As far as I know, only the first three are used with in any large volume on Wikimedia projects so far. And finally, of course, NARA has both an online catalog and an authority file, so catalog records themselves are also different, using the form:

Catalog record IDs go by the name "National Archives Identifier", but I am not sure if there is a preferred name for authority record IDs (it would not be "ARC"). I will have to check on that.

Dominic, do you think it would be reasonable to have 1 property for NARA-ARC ID and 1 property for each of the NARA types -- e.g. 'NARA person ID', 'NARA organization ID', etc.? Regarding this 'NARA-ARC' property, even though the ARC catalog is no longer supported, I'm guessing that there might be users interested in looking up things by legacy ARC ID. Perhaps having both the new and old NARA IDs on the same item would help users like zh:Template:Authority control migrate from NARA ARC to the new recommended NARA type IDs. Emw (talk) 01:30, 6 January 2014 (UTC)
Sorry if I was unclear. What I meant was that ARC and the new catalog ("Online Public Access", OPA) are the same in all respects—same data, same IDs—except it's a different URL structure that takes you to a catalog with a better interface and different name. But they are interchangeable, which was why I was able to the vast majority of ARC links on Wikimedia projects already just by changing a few of the templates that generate links. So what I am saying is that all NARA IDs should be generating links, and links are never necessary; this doesn't break anything, just offers more functionality. Similarly, no properties should be named with "ARC" in them.
To your other point, I would suggest 1 property for catalog records, i.e. "National Archives Identifier", and 1 property for each of the authority record types (unless you think we should limit it only to the most common types). It is conceivable that there could be multiple authority record IDs with different types for the same Wikidata item—for example, the state of Mississippi could be an organization, an geographical location, and a subject. I think we would probably want to call them something like "NARA person authority record identifier" to be specific. I sent an email to our authorities staff to ask if they want to weigh in on any of these issues. Dominic (talk) 04:04, 6 January 2014 (UTC)

Proposed byLavallen (talk)

The exact syntax of this property, am I asking @Lokal Profil: about. Lavallen (talk) 14:09, 6 March 2014 (UTC)

Having one property for all of these might be a good solution. I would skip the "/html/" part though and instead just use "raa/fmi/10028200010001" etc. Links to the entityUri would then be generated though{{kulturarvsdata}}. The Initial part of the string could also be limited to only a list of valid combinations.
It's worth noticing that an entity could have several of these entries. My worry therefore would be that it might be harder to identify which of these is which for inclusion in templates. To give a practical example
Lund Cathedral (Q1236689) has both raa/bbr/21300000022524 (facility-level) and raa/bbr/21400000439699 (building-level) and in this case it is the only building in the facility;
from a usability point of view it would then be easier to split the property up into 'bbr-facility', 'bbr-building' etc. (there are a lot of them though). /André Costa (WMSE) (talk) 16:55, 6 March 2014 (UTC)
The version without /html/ links to an api-version of the file, that's great! It's simple to modify the link in WP/Commons to make it readable for ordinary users. The only drawback is that it's maybe not as simple to make human readable links with the present Gadget, but that is of less importance.
The 'building/facility-level'-problem, I think, could be solved by some kind of qualifier. As far as I have understood, it's ~25 museums related to kulturarvsdata, except for the buildings, old tombs and rockcarvings etc. That could make an awful amount of properties. -- Lavallen (talk) 17:46, 6 March 2014 (UTC)
A qualifier could probably solve this yes. For some of these museums the URI is built up using the internally used code/name of the object, for others a separate property (such as RAÄ-number below) might still be needed. Still that would not diminish the value of this property. /André Costa (WMSE) (talk) 11:22, 7 March 2014 (UTC)
@André Costa (WMSE): Can you provide more examples, than fmis and bbr? -- Lavallen (talk) 11:39, 10 March 2014 (UTC)
sv:Kategori:Externa länkmallar via K-samsök has the current encoded ones. Many of these are for specific objects in museums though and are as such less likely to be useful on wikidata. But as an example we have for the quite famous File:Porträtt, Rudolf II som Vertumnus. Guiseppe Arcimboldo - Skoklosters slott - 87582.tif.
All the available services are listed at [9] but the descriptions aren't always clear, some of them should be grouped and they don't always coincide with the uri. /André Costa (WMSE) (talk) 12:58, 10 March 2014 (UTC)

Thanks. Ping me if you need more info on the constraints. Which would the suitable property be for the dataset/service qualifier?

I tested catalog (P972) now in Uppland Runic Inscription 932 (Q7899135). I have doubts if it is a correct use of that property, but maybe we can propose a new property for this. @Paperoastro, Zolo: applies to part (P518) may fit when there is several database-items for the same item. Like when both fmis (cultural heritage) and bbr (protected buildings) have an item for the same object. -- Innocent bystander (talk) (The user previously known as Lavallen) 15:29, 29 April 2014 (UTC)
I now also tested to use RAÄ number (P1262) as qualifier when fmis is used. I also tested an unorthodox way of using P387 (P387) -- Innocent bystander (talk) (The user previously known as Lavallen) 15:38, 29 April 2014 (UTC)
I think P438 (P438) is more suitable than P387 (P387) (left a note on the talk page).
applies to part (P518) may actually be the best fit. catalog (P972) would in part be implicit of the kulturarvsdata property itself whereas applies to part (P518) clarifies which of the individual datasets it comes from. What would then be needed would be the opposite property (i.e. X is a dataset in kulturarvsdata). /André Costa (WMSE) (talk) 07:40, 30 April 2014 (UTC)

Granted, the functionality of the CONOR.SI database is rather limited for now, but it's a relatively new thing that is being actively developed. However, it does list alternative author names which constitutes added value. And no, the :slwiki template doesn't access content by name search, where did you get that idea? — Yerpo Eh? 09:13, 24 April 2014 (UTC)
Sorry, on first inspection I somehow have missed to recognize the authority entry for CONOR.SI at sl:Zofka Kveder and thought that {{Dlib|ime=Zofka Kveder}} would trigger the category listing. Indeed the category is filled by the Lua module and directly reflects usaage of the CONOR.SI parameter (I got my number above indirectly by sl:Posebno:LinkSearch). BTW do you know if there is a relation at all between Digitalna knjižnica Slovenije and Virtualna knjižnica Slovenije and especially whether there are plans to make the digital content accessible via CONOR identifiers? -- Gymel (talk) 12:08, 24 April 2014 (UTC)

|robot and gadget jobs = No current bots or gadgets as far as I know. Someone could do data collection: The Yahoo GeoPlanet API already contains support for English Wikipedia page ID concordance as value "wiki" (as well as several other cross-reference values) in the /concordance data. Where the page ID doesn't exist in the Yahoo data, a bot could be designed to add the WOEID to Wikidata items when there is high confidence: for example, if there is a located in the administrative territorial entity (P131) of type second-level administrative country subdivision (Q13220204) for the Wikidata item, and that matches exactly one name in Yahoo GeoPlanet with the same Admin2, and the name is not ambiguous on the native language Wikipedia (i.e. needs unusual qualifiers in the title), then the item on Wikidata would have a high-confidence match to that WOEID. Or a gadget could allow user-assisted matching. |proposed by = Closeapple (talk) }}


Q7953796 ("Where On Earth Identifier") is a numeric identifier assigned to individual places for the Yahoo GeoPlanet (formerly Yahoo! Internet Location Platform) location database, which includes major buildings, parks, neighborhoods, cities, states/provinces, countries, continents, and seas (see Response Data Elements for a list of place types, and Place Types for a subset used for regional divisions). It appears to be useful for Wikimedia purposes because:

  • Its design standard is similar to other authority control numbers: The GeoPlanet "Key Concepts" page states that "WOEIDs are unique and non-repetitive, and are assigned to all entities within the system. A WOEID, once assigned, is never changed or recycled. If a WOEID is deprecated it is mapped to its successor or parent WOEID, so that requests to the service using a deprecated WOEID are served transparently."
  • It's the authority control number for the place names on Flickr pages: click on the location on a Flickr page and you'll see it link to a WOEID. The API (if you have access) also allows one to find nearby place names. If someone wrote the right code on Commons, that would reduce errors in bot and upload autocategorization on Flickr, since the text description (and/or coordinates) could be compared to the Flickr location name, to make category guesses with more confidence and thus less annoyance; for example, if the place name from Flickr also matched a word in the description, it would be more likely that the proper category is the one with that ID.
  • WOEIDs are assigned to neighborhoods and points of interest, not just legal administrative divisions.
  • WOEIDs correspond to GeoPlanet database entries with extensive parent and child location information.
  • The GeoPlaces database already has concordance to some English Wikipedia page IDs, and also contains several other concordance links.

A caveat, which probably isn't relevant to approval here: If a programmer were to use the Yahoo GeoPlanet API as a source for these, Yahoo seems to allow a single application user only a few tens of thousands of requests per day, equivalent to a request every 2 to 4 seconds. Closeapple (talk) 01:09, 25 April 2014 (UTC)

  •   Support in addition to accessing the structured metadata within GeoPlanet, it is used by APIs such as the flickr API, and it also provides a simple way to jump across to resources in other platforms (such as flickr) as demonstrated in the examples above.

@Tobias1984:followed by (P156) only for two items exists at same time; structure replaced by (P167) only for building and structure; this for organization/regime. see Ivan A. Krestinin's comment at "replaces" section at Wikidata:Property proposal/Place.--GZWDer (talk) 17:56, 4 February 2014 (UTC)

structure replaced by (P167) is for buildings (and similar) only. So, has no relevance to organizations. Also, in English succeeded is much the same as replaced in the context of positions of authority. Danrok (talk) 16:35, 7 February 2014 (UTC)
followed by (P156) is used for series of books, albums, TV shows where an item is not replaced by a following item. This is a new property for cases where an organisation item is replaced by another item.

Motivation. Xaris333 (talk) 17:44, 31 March 2014 (UTC)

@Xaris333: The current paradigm of Wikidata is to make properties time independent. So instead of limiting the property to "last season" I would use "league season + time qualifier". In that case you can link to all seasons that have a Wikidata-item:
Real Madrid CF (Q8682)
league season: 2013–14 La Liga (Q6086248)
Qualifier: Point in time: 2013-2014
league season: 2012–13 La Liga (Q720018)
Qualifier: Point in time: 2012-2013
I generally think we need to store this information, but I also don't know if this information could also be queried in a different way. Or even stored in a different way. After all the season of a leuage is a subclass of the leauge itself. If a club played in that leauge it also participated in that season. But until we have that technical capability we might need to use a more direct approach. --Tobias1984 (talk) 20:57, 1 April 2014 (UTC)
I agree. And the most recent completed competitive league season to be at the top of the list. Xaris333 (talk) 21:05, 1 April 2014 (UTC)
  Oppose. This is too specialised. We need a generic property for all athletes/sports teams/candidates competing in sports leagues/races/elections. Renames this as "Participated in" or "Competed in" and move it to Property Proposal/Event I will support. Filceolaire (talk) 15:04, 14 April 2014 (UTC)
As you have season items like 2013–14 La Liga (Q6086248), just add "participant (P710) Real Madrid CF (Q8682)" and start time (P580)/end time (P582) to the them. The rest is deducible.  — Felix Reimann (talk) 09:50, 19 April 2014 (UTC)

@Xaris333: This also needs time qualifiers (start and end date). League position changes after each game day. But that is the resolution we need in order to make sense of this property. Things like "best position 2012", "worst position between 2000 and 2005" can then be queried. That sounds like a lot of data now but we will probably laugh about this once Wikidata reaches Giga- and TeraStatements. --Tobias1984 (talk) 21:02, 1 April 2014 (UTC)
The idea (due to the template) was to have the final position of the last completed season. Xaris333 (talk) 21:04, 1 April 2014 (UTC)
@Xaris333: It is of course difficult to talk about things that are still work in progress, but I am pretty sure we will be able to query the final position of the season with some Lua-code. In general it would be good to only gather the final position in the beginning until more complex data sets can be easily queried and implemented in the infoboxes. --Tobias1984 (talk) 21:23, 1 April 2014 (UTC)

Another bot could later fill the item from de:Template:Munzinger, parameter 1, but I'd rather like to edit the data manually before such a bot run, since the template is also in use as reference in non-biographical articles (e. g. the template is in an article about a company, while the Munzinger article is about the CEO of that company, not the company itself).

Proposed byAndreasPraefcke (talk)

The (quite large) BEACON files already cover those people that also have a GND authority entry. Munzinger Archiv features many more, though (e. g. sportspeople or diplomats). The Munzinger Archiv products have been a well-known biographical source since way back in the pre-digital age, and the website is freely accessible to many public library users throughout Germany. Even without this possibility, the website features information as to dates and places of birth and death and the formation of the described persons within its free parts that are of some use to users. --AndreasPraefcke (talk) 15:16, 25 April 2014 (UTC)

Alternatively, there could be six different properties (each with only one entry per Wikidata item) for each of the products:

  • Munzinger Sport

  • KDG Komponisten der Gegenwart
  • KLG Kritisches Lexikon der Gegenwartsliteratur
  • KLFG Kritisches Lexikon der fremdsprachigen Gegenwartsliteratur

--AndreasPraefcke (talk) 15:20, 25 April 2014 (UTC)

  Question You mention "the Munzinger Archiv products": Should therefore (in the one-property variant) any value for this property be accompanied by a qualifier noting the Wikidata item of the specific product it applies to? Could that be part of (P361) or collection (P195) - I have no idea wether these are intended to use as qualifiers: It is not the item (i.e. person) which is part of the database or (sub-)collection but rather only the biographical essay referenced by the proposed property. Or would rather be stated in (P248) mandatory even it this might suggest the data here would acctually have been ingested directly rather than imported from intermediate lists? -- Gymel (talk) 22:13, 25 April 2014 (UTC)
Actually, the first two digits of the ID stand for the "product". 00: IBA, 01: Sport, etc. Probably six different properties are best, for future use of Wikidata data within Wikipedia articles. I'd still rather like the whole 13 number ID in the database, regardless if it is somewhat redundant, since everything else is bound to cause difficulties. As to a "source" fields etc., I don't know much and I don't care at all, since I have never found any of those to be of any use before. --AndreasPraefcke (talk) 14:08, 27 April 2014 (UTC)
I would like to   Support the proposed approach of six different (and otherwise "unqualified") properties with "compatible" (i.e. complete) identifiers and the opportunity to impose an additional uniqueness constraint on the values.
The sidebar of the Munzinger corporate home page lists "Munzinger Personen" (IBA?), "Munzinger Sport" and "Munzinger Pop" as one "Biography" Group and "KLG", "KLfG", "KdG" together with the famous KLL (Kindlers Literatur Lexikon, in contrast to the former not even a biographical sketch is shown, just a login prompt) and other more encyclopedia-like products in a different section: I would propose to decoupple at least KLG, KLfG and KdG to property proposals of their own. -- Gymel (talk) 16:06, 27 April 2014 (UTC)
