Proposed byKolossos (talk)
Discussion
Motivation

I'm trying also on a low level of objects to link between OpenStreetMap and Wikipedia/Wikidata (see project WIWOSM), but with this proposed property I try to link between projects on the higher level of classes. These object classes are represented in Openstreetmap by the tagging schema. I would try for each entry in "Map_Features"-site (see source) to find an item in Wikidata. So I see a usage for this property only for some hundreds of items. If it's not matching exactly, I would not fill this property. At some points we will have discussion, because it is definitly not easy in each case. So we would learn where both projects matching good and where not. Perhaps we see that the structure in OpenStreetMap is for some point better than ours. Benefit can be in both directions Wikidata would get some map-icons and OpenStreetMap could profit from the translations in Wikidata. Later, tools can use this links so that we could compare e.g. all lighthouses in OpenStreetMap with all objects that are instances of class lighthouse (Q39715) and so on.

After approval I would need some help for the template that generates the URL's. I would also try to add this connection of both projects in taginfo so that we would have this link also in the backward direction. --Kolossos (talk) 19:19, 12 April 2014 (UTC)

  Support. Sounds to be useful. Where do you plan to place the links apart from one of them at the item page using MediaWiki:Gadget-Preview.js? Isn't there yet a connection at least from one to the other? Do you want to have both at the item talk page? Regards, --Marsupium (talk) 12:59, 13 April 2014 (UTC)
  Comment Surely the link to the OSM-Wiki is more important, because it's closer to the heart of OSM. This link will go to the English description page, and on each of these pages is a small link to Taginfo. Also Taginfo has links to the OSM-Wiki in different languages. So if you and others are thinking two links are to confusing, I can live with one link to the Wiki. Taginfo is more technical and provides statistics, links to Overpass-Turbo and JOSM. --Kolossos (talk) 16:15, 13 April 2014 (UTC)
  Support. After disussing some questions I understand, that this fits with the possibility easy to make maps out of Wikidata. I can use this also here in east germany, poland and czech via [1]. Conny (talk) 19:21, 14 April 2014 (UTC).
  Support I also discussed this with Kolossos and got convinced very fast. This will be a very powerful link to show geographical items on maps and much more. As said this property will be used on few high-level items, e.g. bridge (Q12280). Every item that's an instance of (P31) bridge (Q12280) will then be linked to the corresponding OSM tag. --Thiemo Mättig (WMDE) 16:49, 17 April 2014 (UTC)
  Weak support. I think this should be implemented, but in a cleaner way than what's proposed above, e.g. with property name "OpenStreetMap tag" and without including the "tag:" prefix in the values, as that would be redundant. Also, it would be better if the values were not free-form text (i.e. strings), but an item instead (not sure that's the proper term within Wikibase's data model); That way the data model would be cleaner since tags can only be added if they're already presented in the Wikidata system. We could also include a threshold for adding such tags to the list of OSM tags in the data model, something like a minimum of X usages as counted by Taginfo. This approach would help consolidate the tags (since adding a new tag isn't left to a user's sole discretion as happens in OSM), and would also make it easier to manipulate geodata without doing a lot of string parsing. --Waldir (talk) 15:22, 26 April 2014 (UTC)
  Comment The "tag:" is not redundant, because there exit also some rare cases of "key:" e.g. Key:admin_level. We should have the flexibility to support theses cases. A cleaner way would be in my eyes to split "key" and "value" in two separate fields of one property, but this seems not possible. The tagging in OSM is OSM-specific, so I see no link to Wikidata-items, e.g. not everyone would combine "prisons" in the category "amenity"[2]. Also for object classes with small number of items I see a small risk of miss-using this feature. It will be a lot of work to support only entries of the map feature page. --Kolossos (talk) 16:41, 29 April 2014 (UTC)

Proposed bySlomox (talk)
Discussion

Many populated places were founded before writing became common in that part of the world. So we don't know when the places were founded, but at some time they suddenly appear in written records. Munich (Q1726) was first mentioned in the Augsburger Schied (Q760561) from 1158. The relevant information is the time, so the property should be of type "time" and the exact record (Augsburger Schied) can be optionally stored as a qualifier.

Besides the most obvious use case, populated places, this property could be used for many other items as well. For some people we don't know their birth and death dates, but we know that they appeared in records at some time and vanished from them later. The same applies for buildings, institutions or even whole people (like the Chauci (Q168549) being mentioned in 12 BC for the first time). Slomox (talk) 10:47, 5 February 2014 (UTC)

Maybe "time of first record"? Their existence isn't always written e.g. hieroglyphics. --Izno (talk) 16:22, 5 February 2014 (UTC)
Good idea. Not sure what should be the extent of this property though… Note sure it's a good idea to mix it with a floruit (Q36424).

Of course retrieving the instances list by a query is possible, but closing the list, as in saying there is only and will ever only have this precise list needs to be indicated. By the number of instances and the number of results in the query this is possible, or by a sequence of followed by (P156) terminated with followed by (P156) we got another possibility, but we must still keep this problem in mind.

One of four properties I'm proposing to handle approximate dates. Wikisource will need something like this for several authors, Commons probably needs it for some creators and Wikipedia for some biographies. It can be used for other things, in the same way as the standard term, for when those things have "flourished". - AdamBMorgan (talk) 21:30, 16 April 2014 (UTC)

I'm a bit uneasy about this. The two examples you give each refer to a single year from which I am guessing that these authors are known for a single publication in which case why not just use notable work (P800) to link to that work? Other cases will need a start and end date for Floruit. It probably won't do any harm though and it will be on a limited enough number of items that it can be changed later if need be. Filceolaire (talk) 21:34, 17 April 2014 (UTC)
The examples were just the first I found. There are more on, for example, WorldCat or the Dictionary of National Biography, I just needed some that already had data items. Many do have a range to show when they are known to be active. "Floruit" is pretty standard for this sort of this; it's the only to date some authors and creators. - AdamBMorgan (talk) 01:51, 19 April 2014 (UTC)

A qualifier to help handle unknown and uncertain dates. Where the official date is "between X and Y", this will be X. Personally, I intend to use it for authors: for example, set date of birth (P569) to unknown value then use this and another qualifier to set out the bounds of the period in which the author was born (rather than just leave it unknown or set to a generic decade or century). It could be used for other events with uncertain dates, however. - AdamBMorgan (talk) 21:41, 16 April 2014 (UTC)

Another qualifier, the last of four proposals to help handle uncertain dates. Circa is a common term (see circa (Q5727902) for reference) but one not currently supported by Wikidata to the best of my knowledge. With this qualifier, any date could be set to unknown value and the "circa" qualifier used for an clear approximation. This will be needed to fully support Wikisource and it will also be needed for Commons (creator biths/deaths and creation dates) and Wikipedia articles. - AdamBMorgan (talk) 22:09, 16 April 2014 (UTC)

  Oppose. There is already provision for dates to have an uncertainty which can be set to a month, a year, a decade, a century, a millenium etc. using the current UI. Filceolaire (talk) 21:21, 17 April 2014 (UTC)
True, but that's rather clumsy. The academic use of "circa" doesn't come with a defined degree of error but it's usually based on some research to narrow it down to something at least a little more specific than a decade (which would be the most likely of the existing options). We would be losing some precision if this information is not recorded. Selection by decade also has a problem at the borderlines: for example, "c. 1855" is straightforward enough but is "c. 1850" in the 1840s or the 1850s? The actual date could be in either decade; the user making that choice increases the potential error in the data held. (As a qualifier, it could also actually be paired with a date set to a decade, rather than the "unknown value" as described.) - AdamBMorgan (talk) 01:45, 19 April 2014 (UTC)
The data structure and API actually allow you to specify a date like "between 1846 and 1855" or "between Apirl 18 and 23 1956". All that is needed is a bit of user interface code to allow dates like this to be entered directly.

Motivation. References are always supposed to support the claim, but this qualifier is needed to represent counter-claims, when another source just says that the statement is dubious.--Micru (talk) 08:57, 7 May 2014 (UTC)

  • The idea sounds interesting but I am not sure I understand how you propose to implement it. I guess we should have both the source that initially made the claim and the source that disputed it in the "references" section, like this ? --Zolo (talk) 07:34, 8 May 2014 (UTC)
    Zolo, yes that would be it. The normal reference and the critical reference will be both in the references section. This qualifier will point out to the one that is being critical with the statement.--Micru (talk) 08:51, 8 May 2014 (UTC)
@Micru:, I think that what Yair rand meant is that this property should be used in the reference section, which is not the same thing as the qualifiers. I agree, and I think you do to, as you supported my example this (it's just that you mixed up the words, sources are not qualifiers). --Zolo (talk) 10:09, 18 May 2014 (UTC)
@Zolo: Not sure if I understood correctly your example. Please check the disputed statement in Waltz No. 17 in E-flat major, Op. posth. (Q16747520) [5] and tell me if that is what you had in mind.--Micru (talk) 15:13, 18 May 2014 (UTC)
@Micru: no actually I had this in mind. I think it makes more sense: this is a statement about what the source says, not really a qualifier of the statement. It is sort of the inverse of p248 (p248: source says X, p1310: source says not X. When transcluded in Wikipedia, I would imagine it in a footnote like: "source: value of p238, for a contrarian view, see value of p1310. ". --Zolo (talk) 15:29, 18 May 2014 (UTC)
@Zolo: The only problem I see with this is that it is not really visible...and it is something you really want to convey clearly. It would be also nice if we could instead qualify the statement with a more generic property that would allow us to add different nuances. For instance calling this property "type of statement" with values "criticism", "uncertainty", etc. That way perhaps we would achieve the needed separation between information/source, plus conveying a different meaning in a visible way, but we would have to add the statement twice with the same value, one of them qualified with "type of statement:criticism". What do you think of it?--Micru (talk) 16:28, 18 May 2014 (UTC)
@Micru: on the face of it, it seems attractive to have "type of statement" as a qualifier in addition to "disputed by" in the source, but it makes the structure more complicated. If you want to say "composed by Chopin according to X but not to Y" you have to specify that "type of statement = criticism" only applies to source B and not to source A. And if you want to put "type of statement" as a qualifier rather than in the references, it seems that you need to have 2 "composed by Chopin" statements (1) "composed by Chopin source: Kobylańska Katalog" 2) "composed by Chopin type of statement "criticism", source Chomiński catalog"). That said, it may be ok to do it that way. Something similar seems to be required for other qualifiers (if you want to say: composed by Chopin determination method (P459) musical analysis, source A and composed by Chopin determination method (P459), handwriting analysis, source B, you may also need two different statements).--Zolo (talk) 20:28, 18 May 2014 (UTC)
Yes, that was what I meant. Using the property in the references section makes for a clearer division between sources of statements and the statements themselves. There are some clear problems with this, but I think they're less severe than the problems posed by putting source data in as qualifiers.
It also occurs to me that in certain cases, one could just reframe "X says the value of Y is not Z" as "X says the value of Y is (unspecified, maybe "unknown") but definitely not (qualifier) Z", by using a separate statement. --Yair rand (talk) 00:21, 19 May 2014 (UTC)
Zolo, Yair rand: If we change the name of this property to "type of statement" (to be used as Zolo described), then this property can also be used to capture uncertainty as Random knowledge donator requested on the project chat. Any concern about it?--Micru (talk) 11:14, 19 May 2014 (UTC)
Yes, if we're going to touch the roots of Wikidata, we need a clear plan, usecases and a RfC. These are complex questions. TomT0m (talk) 11:47, 19 May 2014 (UTC)
Thinking some more about it "type of statement" does not sound like such a good idea. If X shows that Y it is not by Chopin", then if X is the most authoritative source, we would have something like "composer: Chopin, type of statement: refutation, rank:preferred". But rank = preferred means that it will be the value retrieved by default. And if the client does not analyze all qualifiers (which would be a very stringent requirement), which means that it is likely to get "composer: Chopin" while it should really be "composer: not Chopin". So I'd say that we should stick to "disputed by" in the source (in this case: "composer: Chopin, source(stated in Z-disputed by Y), rank: deprecated. We also have the issue that 3 ranks may not be enough and that ranks conflate relevance and reliability, but if we are displeased with that we should try to have a built-in solution (split into relevance rank and reliability rank, and/or add levels). Trying to get around that using qualifiers appears to make the structure rather confuse. --Zolo (talk) 17:58, 19 May 2014 (UTC)

Discussion

I think we need licensing information on Wikidata but I am not entirely sure how to approach this best, so I am posting here to get the discussion going. As for data type, it may be useful to be more specific (e.g. CC BY 4.0 - or perhaps even the language- and country-specific deeds - instead of Creative Commons Attribution (Q6905323)). As mentioned in the allowed values, it would make sense to include things like CC0 or PD here, but both are technically not licenses, so perhaps the property would have to be named differently. In principle, it would be desirable to extend this beyond CC licenses, so I have opted not to put CC into the property name, but I can see that it would also make sense (particularly now that no good repository of other licenses exists) to make this property more specific by naming it CC license or open license or some such.

Discussion

@Napoleon.tan, Snipre, Tobias1984, Presentime, Pere prlpz: please comment. GZWDer (talk) 16:00, 14 January 2014 (UTC)

  OpposeI see two reasons for not creating this property:
  • as already said, blood type is a medical data and medical data is particularly sensible. And even if they is a source I am not sure that everyone accepts the spreading of this kind of data. Just an example: blood type is depending on the parents blood type and by in some cases analyzing blood type within a family can show biological relations which are not corresponding to the legal relations (to be simple, in some cases this can show that a child is not the biological child of 2 parents). So if this can be public in some way this doesn't mean that everyone wants to see this kind of information largely published.
  • then the question is to know if this kind of information is easily accessible for a large number of persons. Blood type is not a characteristic of a person, this doesn't say anything about him. I know that in some countries blood type like Japan is important but if this concerns only the japanese Wikipedia perhaps this doesn't need to be on wikidata but can stay on the japanese infoboxes. If this information is only available for some thousands of persons and is interesting only few wp's, I think we can discuss about its usefulness at a worlwide scale. This is a personal point of view but a database with a lot of properties but not filled in a systematic way is not very interesting, I prefer few properties which are present in most items of the same class offering a real added value in term of query and analysis.
Can someone estimate the percentage of persons infoboxes in the jp:WP which have this property filled ? Snipre (talk) 18:05, 14 January 2014 (UTC)
  • Privacy: This property can be used based on reliable source. I would add only with reliable, publicly accessible, secondary sources. Then we won't make public any data which is not public already. Anyway, I think there will be a lot more people worried by us publishing their age, names of parents or sons, ancestry, criminal history, or other data about them, than people worried by us spreading their blood type. Furthermore, publishing it in wikidata or publishing it in Japanese Wikipedia makes no difference.
  • Utility: I must admit that being interested in celebrities'blood type sounds bizarre to me. Anyway, if some people from another culture or with different interests than me are interested in bloody type, I don't see any harm in helping them to get that information. In fact, since it is part of human knowledge published in reliable sources, giving access to it is in line with WMF goal.
  • "World-wide": If just one WMF project was going to use this information, you could be right that Wikidata won't be of great help in such job and information could be just stored locally in infoboxes. But if such information is going to be used by two projects (e.g. Japanese and Korean or Ainu wikipedias) or more, Wikidata can be a great help.
On the other hand, I don't expect most Wikipedias using this property. Therefore, having it for Japanese use won't make blood type appear in enwiki infoboxes.--Pere prlpz (talk) 20:17, 14 January 2014 (UTC)
I am not sure that only the limited information of these four types: "A,B,AB,O" would be enough to prove that somebody is or isn't related to each other. If you find a piece of clothes from Thirty Years' War (Q2487) in Germany and find A-type blood in it. Then it's suddenly more likely that the owner comes from Sweden, but it does not prove anything. (And this example comes from real life.) -- Lavallen (talk) 20:30, 14 January 2014 (UTC)
@Lavallen: Just have a look at this. This can't be used for all cases but they are some constrained cases. Snipre (talk) 21:00, 14 January 2014 (UTC)
@Lavallen: Blood types can be used to prove that a given person is not the offspring of a certain couple. This is the main reason to use this property only when blood type has been published by publicly accessible secondary reliable sources.--Pere prlpz (talk) 09:23, 15 January 2014 (UTC)
@Pere prlpz: Here we reach the problem: what is a reliable source for this kind of data ? Again, as it is a normally a medical data, the only person who can say the blood type is the person itself: there is no public document with this kind of data unlike for names, age or adresses. All other sources are problematic because you don't know how they get the data and if the person of interest gave his agreement. This is a problem for living persons, for dead persons you can assume that some documents are public. For me reliable sources are not enough, an agreement or a public declaration of the person of interest about this data is necessary in order to respect the private life of the persons. You can find a lot of data from people press (relationship, disease,...) but in some cases the persons laid some complaint against the newspapers: can we use this kind of information in that case even if the data is published ? Snipre (talk) 13:20, 15 January 2014 (UTC)
@Snipre: We have long worked definitions of what a reliable source is in all Wikipedias. We can treat reliable sources about blood type just in the same way as we treat reliable sources about any personal data. For instance, how do you know age, marital status or number of children of any notable people? You just check in books, newspapers or other reliable sources. If there is no information in any reliable source about a certain property for a given person, we just don't use that property for that person. For example, most of people with infoboxes in Wikipedias don't have information about spouses - it happens in Wikipedia in the same way as it happens in reliable sources. Very few people is expected to have information in "blood type" property, a lot less people than nearly any other personal data. This is not a problem. This is just what reliable sources do.
The only difference between blood type and other potentially private data (let's say, age) is the number of notable people with coverage by reliable sources and the number of readers and wikipedias interested in using it. Although, except for quantity, blood type is not different from age.--Pere prlpz (talk) 17:18, 15 January 2014 (UTC)
  Support I think this is reasonable. We can add it to people where it has relevance and can be sourced. It can also be used as a qualifier for medical topics. Certain diseases are tied to the blood type and we should be able to express that. --Tobias1984 (talk) 10:34, 15 January 2014 (UTC)
This information cannot be added if not the person him/herself has provided it. The person hirself is the only primary source except for medical journals, which we never have access to, and never should use. I'm afraid that the published blood-type therefor sometimes is fake, but I cannot see that as a problem. Wikidata will never be used to give medical treatment to these people. -- Lavallen (talk) 19:55, 15 January 2014 (UTC)
Look at this example: en:Blood type distribution by country. That is information we need to bring into the database. We are not going to add it to every person on Wikidata, but probably to a few people where it hase relevance. But we also need to store statistical information and the information how blood groups make certain diseases more likely. --Tobias1984 (talk) 11:41, 16 January 2014 (UTC)

  •   Oppose. First, this is medical data, and as such subject to additional legal protection in many jurisdictions. I anticipate needless complications arising from this if Wikidata collects such data. Second, it is not useful for the purposes of our projects, as the only real use of this data is in actual medical applications, for which no professional would rely on Wikidata. The apparent facetious/prurient/superstitious interest in this data as related to celebrities in Japan appears to me to be not within the scope of the purpose of our projects. Sandstein (talk) 20:47, 6 April 2014 (UTC)
  Support. I like to think no data is beyond the scope of our project, provided it is useful to someone and properly sourced. Blood type is big in Japan, the Japanese Wikipedia uses it, so I can't see why we shouldn't include it. As per the legal issues, by using this property we would be republishing data that is already public. If someone tried to defame someone on Wikidata using their blood type (I can't quite picture that, but let's imagine), the data would have no source so the claim would be removed. Mushroom (talk) 22:30, 6 April 2014 (UTC)

Just as occupation:sportsperson can have the property sport (P641):long jump (Q170737) so occupation musician can have this property.

It can also be used as a qualifier to performer (P175) on an album or a single item to specify what each performer did on that item just as character role (P453) can be used to qualify cast member (P161) on film items. Filceolaire (talk) 12:55, 14 April 2014 (UTC)

  Question However, to be strict, values must be of type civic community (Q1021096)? For most items these simultaneously are municipality of Switzerland (Q70208) as subclass of municipality (Q15284), but in other cases like Bern (Q70) and civic community of Bern (Q1014896) they are (since 17something or much later?) extremely distinct? -- Gymel (talk) 09:58, 10 May 2014 (UTC)

But considering Leo Merz (Q2800146), HLS: "Merz, Leo // geboren 13.7.1869 Thun, gestorben 21.9.1952 Bern, christkath., von Hägendorf und Bern". Isn't it that he died in Bern (Q70) but the proper item for his Heimatort Bern should rather be civic community of Bern (Q1014896)? -- Gymel (talk) 12:17, 10 May 2014 (UTC)
Values for Leo Merz (Q2800146) would be Hägendorf (Q67184) and Bern (Q70).
civic community of Bern (Q1014896) is a more like a corporation of citizens than a "place of origin". While he as alive, Leo Merz may be been entitled to participate in that corporation. Some of the civic community (Q1021096) limit benefits to citizens that are also resident in the municipality. --- Jura 12:51, 10 May 2014 (UTC)
But isn't it true that any person "heimatberechtigt" in Bern is member of the Burgergemeinde by birth and opting out is impossible except by changing the Herkunftsort to some other place (I'm aware of the fact that the incorporatedness of the Burgergemeinde Bern is somehow exceptional even for Switzerland but otherwise there is no difference)? -- Gymel (talk) 16:20, 10 May 2014 (UTC)

Discussion

The primary identifier allocated & used by Australia for people, organisations and places, including subjects with no relation to Australia. It is led by the National Library of Australia (Q623578), all other significant Australian libraries are members of the consortium, and they are integrating other datasets built by organisations, and is now a mandated part of research data at universities[10]. 'Trove' is the public website to access the data, 'People Australia' is a funded program to hold/build the dataset.

Regarding automation for population of this field, the NLA party ID exists on ~250 Wikipedia pages (see w:Special:LinkSearch/nla.gov.au/nla.party), however the People Australia records can be correlated with Wikipedia entries via identifiers that are common to both, such as Template:Cite Australian Dictionary of Biography (Q6703319). John Vandenberg (talk) 07:47, 6 April 2014 (UTC)

  Question John: How does this identifiers compares with Libraries Australia ID (P409)?--Micru (talk) 18:14, 30 April 2014 (UTC)
  • @billinghurst, Micru:, the simple explanation is that Libraries Australia ID (P409) is one of several identifier for authors/subjects of items held by libraries in Australia, and is managed using librarian practises without public use as a after-thought (it is like a national OCLC number), whereas the party id is a unique identifier for things known by any contributing member to the open consortium (which includes major datasets already built by large groups, but every Australian academic can also contribute individually) with Libraries Australia only being the primary dataset and the NLA acting as manager, and is managed using modern minting practises via modern protocols, with use by the general public as the primary objective. For NLA identifier 35411562, which is Andrew Barton Paterson (Q436699) the NLA party record is nla.party-514760 (as EAC 2004++ XML), where you can see 35411562 and many more identifiers listed, making this the primary entry point into Australian public datasets (esp. research, but other federal funded programs are also requiring grant recipients align themselves with NLA party IDs).

I am not sure that renaming NLA is necessary, it aligns with VIAF usage, and our nomenclature. I would agree that this proposed property should not be that similar so it can be differentiated, and wonder whether it should be aligned with something like "PeopleAustralia-identifier".  — billinghurst sDrewth 14:49, 6 May 2014 (UTC)

'Trove' cant be in the name, as 'Trove' is a front-end website that uses many different IDs, and it does not mint these IDs. 'People Australia identifier' would be acceptable to start with, however this identifier is also for other types of entities such as CSIRO (see examples). This proposed identifier is called NLA party ID[11], or NLA Persistent Identifier. Property:P409 should probably be renamed, as it is actually the Australian National Bibliographic Database identifier (which was based on the 'Australian Name Authority File', which uses different IDs), and is served via the 'Kinetica Service'. It is common to call Libraries Australia ID (P409) the 'AuCNLKIN ID', where AuCNLKIN is the MARC Org code for 'Australian Commonwealth National Library Kinetica Service'. It is also common to call the old NLA identifier the 'Libraries Australia identifier'. Whatever we call them, I think we will need to add notes into the description to help the user pick the right property, and periodically run a bot that resolves the property values to detect if the wrong property has been used.

@Zolo, Lavallen, FelixReimann, GZWDer, Jakec: It's that, or we use part of, I would prefer that. It apply to any kind of lists, the type of the list is a good information of the kind of sequence, so it seems generic enough to me ... TomT0m (talk) 22:27, 15 February 2014 (UTC)

So an item like "Astronomical naming conventions for minor planets" (I am not aware of any item like that today) would fit for example 4 Vesta (Q3030). That sounds good!
But I have mainly used P155/156 for the evolution of administrative division (see Ytterlännäs rural municipality (Q13604045)). Would communal reorganisation (Q1497011) fit for such items? - Then, I am not sure "part of" would fit for that purpose. We maybe need this new property, then? -- Lavallen (talk) 05:54, 16 February 2014 (UTC)
@Lavallen: I guess the most accurate list for that would link a geographical territory item, such as an item for an urban area with the local jusrisdiction in which he belongs, and that the law about the territorial entity is a qualifier or a source for the change of jurisdiction in this case ... I don't realise if it is a realistic solution in this case though.
For example if <urban area X> and <urban area Y> where two <village X/Y(resp)> that appeared to have been reorganized as a single unit <XY city>, we could have <urban area X jurisdictions> as the list item and
⟨ town XY ⟩ follows (P155)   ⟨ village X ⟩
in list Search ⟨ urban area X jurisdictions ⟩
and
⟨ town XY ⟩ follows (P155)   ⟨ village Y ⟩
in list Search ⟨ urban area Y jurisdictions ⟩
... TomT0m (talk) 16:21, 16 February 2014 (UTC)
These are actually municipalities (local political autonomic areas), not urban areas (who are mainly statistical units). (I do not know any good way to describe the succession of urban areas yet.) I do not completely understand what you mean with jurisdictions here. Municipalities of different kinds are of course jurisdictions in themselves, who are independent up to the central government, with one exception. "Municipalsamhällen" did not used to be completely independent to the municipalities they were connected. -- Lavallen (talk) 19:09, 16 February 2014 (UTC)
I think this amounts to the same thing as using this property as qualifier. I tend to like using qualifiers better as it is more concise (we do not have the rather useless repetition "instance of French cabinet" / "in list: French cabinets").
The solution you propose would probably easier to use in templates fr:Modèle:Insérer dynastie but I really don't like those templates :] And for other purposes, using "instance of French cabinet, succeeded by X" is more straightforward, as we avoid intermediate items like history of french governments (Q684321) that might sometimes be machine-confusing or human-confusing. --Zolo (talk) 19:10, 16 February 2014 (UTC)
@Zolo: This does not work if the item belongs to several sequences. For example, a serie episode belongs to a season and to the whole serial. There is several Pierre Laval government in the french Third Republic, which are identified by a number on (working in importing governments into Wikidata :) ) which does not follow immediately on the sequence of governments, there may be albums that are sequel of others in a discography but not chronologically on the same discography ... This may not be useful in all cases but I already seen several cases in which this can be used. TomT0m (talk) 19:20, 16 February 2014 (UTC)
@TomT0m:, that's true that element order may not always be obvious, but I do not understand how this property would improve things. If you want to say that Gouvernement Jacques Chirac (2) comes chronologically just after Laurent Fabius cabinet, but that as a "Jacques Chirac cabinet" it comes after Jacques Chirac 1, how would those two differ:
  1. instance of Cabinet of Francepreceded by Laurent Favius Cabinet / instance of Jacques Chirac (1) Cabinet preceded by Jacques Chirac 1
  2. preceded by Laurent Fabius Cabinet in sequence: Cabinet of France preceded by Jacques Chirac (1) Cabinet in sequence:Jacques Chirac Cabinet
-Zolo (talk) 22:23, 16 February 2014 (UTC)
@Zolo:OK you meant the solution to qualify the type claims. I don't really like these solutions as it seems a little weird for my computer scientisf self to do that, a type usually defines (or is defined by) the properties of its instances. Adding informations when we type something is OK for template type (that defines the concrete type actually) but it's not the case here. In particular, Jacques Chirac Cabinet is a subtype of Cabinet of France. Here in a sense we have two kinds of list, one who is attached to Cabinet of France and one who is attached to Jacques Chirac Cabinet, and we define them when we instanciate the classes, in a sense. Qualify the type claim is kind of an equivalent call a constructor with a parameter in object programming, a notion that absolutely does not exists here. OK, I'm beginning to sort out the node into my head :) here instance of (P31) is supposed to have a typing semantic, like in RDF/OWL. But using following / preceeded by we give it a sequence semantic (to the class), and classes have usually not a list semantic but a simple set of elements semantic. By expressing in separate statement it seems cleaner : we don't mix the two semantics. OWL Punning OWL Punning allows to treat an item as both a class and an individual, so there is no conceptual difficulties for him to be both a class and a list, but using the two semantics in the same claim seems not so clean, or even impossible in systems like OWL punning.
Of course some people in this project do not care of this kind of details or easily overcome by a little data processing when exporting datas (I understand that) but imho trying to be as clean as possible might not be useless (the cost is not very high, just a qualifier and one or two claims). I think Emw would back me up here (even if he would like to be even more aligned with OWL :) ) TomT0m (talk) 22:59, 16 February 2014 (UTC)
@TomT0m:. That seams to make sense. Still I am pretty sure I have seen cases where "preceded by" is not perfectly clear even when we know what sequence it is referring to. I'd like to find some of these before I make up my mind: not sure whether we should have special properties like "chronologically preceded by in sequence", or simply add statements to the sequnce item, like "instance of chronological sequence.--Zolo (talk) 07:26, 22 February 2014 (UTC)
So 'Star Wars A New Hope' would be in 2 lists, one with the sequence in which the films were issued, the other by internal chronology? That could work. See the discussion about Preceded by and followed by and the difference between a series of books/TV shows (previous not replaced) and a sequence of political office holders (each replaces the previous). Going to think some more before voting. Filceolaire (talk) 21:02, 24 February 2014 (UTC)
@Zolo, Filceolaire: Thinking about this a little more, I think it would be better if this property was used as a main property with precedeed/followed by as qualifier, for example
⟨ Toy Story 2 (Q187266)      ⟩ in list Search ⟨ Q2732470 ⟩

No it's not redundant with queries. It's an added information, John might be both preceeded by Pierre as the head of its company and by Paul in its appartment ownership. You can't know which sequence is it just with follows (P155) alone. TomT0m (talk) 12:45, 29 April 2014 (UTC)
You might be able to query anything (appartment owner, head of company) and sort the results by "start/end date", or "date of creation", or "rank" or whatever. precedeed/followed by doesn't seem necessary in the examples you give.--Micru (talk) 12:57, 29 April 2014 (UTC)
Then you don't need follows (P155) and followed by (P156) anywhere. Yet they are very convenient to navigate beetween items. Redundancy is not so much a problem, just because we could do this another way does not mean it's bad. Plus this work if you don't know dates. TomT0m (talk) 15:06, 29 April 2014 (UTC)

It seems pretty obvious, and I don,t see why we'll want to have a bunch of super specific categories ("Authors of plant names work abbreviation", "International Astronomical Union constellation abbreviation"). This is the sort of things people will be adding because it is just obvious, and they will be shoving it in inappropriate properties, and alternative names just don't always cut it (besides, I don't see how this is NOT a useful property in general). Some acronyms (e.g. UNPROFOR) can probably use P743 (P743) (which I found used in Doctor of Philosophy (Q752297), hence the proposal), but I find that property to be annoyingly vague. Besides, an abbreviation can be an initialism in a language and an acronym in another, such as English UN vs. French ONU, only one of which seems to clearly fall under "short name" for me.

I have seen a lot of part of (P361) statements which are used with the same scope. However mass addition of part of (P361) overwhelms the "tree" tool and makes it useless. It makes sense to replace these statements with the new property. לערי ריינהארט (talk) 13:27, 29 April 2014 (UTC)

context can help to increase "granularity" without interfering with the part of relations which should be used for major relations (as the parts of science, major research domains etc.).
context might be regarded as a lexicographic property do distinguish semantically different items. It is not part of the description, it is part of the item and it is machine readable. This may minimize the efforts in adding descriptions for thousand of items. 14:03, 30 April 2014 (UTC)

  Comment It could even be used to suggest properties for the class instances. Say density (Q29539) is linked to a property expressing this relationship beetween an object and a value for example. TomT0m (talk) 16:27, 26 May 2014 (UTC)
  •   Weak oppose. The 'physical object (Q223557)=>density (Q29539)' example suggests this property will be used to unwittingly construct an upper ontology that has lurking alignment problems with major upper ontologies outside Wikidata. A statement about an entity's intrinsic properties is not a suggestion; it formally entails that it has a (possibly unknown) value for the property.
For example, in Basic Formal Ontology 2.0, "photon" is a (distant) subclass of "material entity" and "object", which are analogous to Wikidata's "physical object" item. Photons have no mass, though, so we cannot say that photons are physical objects and also say 'physical object (Q223557)=>density (Q29539)' and also be aligned with BFO. BFO is the most widely used upper ontology in the natural sciences, so it would be advantageous to be aligned with that.
Beyond that note of caution, I would like to see some more background research on how formal ontologies in the wild (or even just in the literature) deal with intrinsicality. As the Stanford Encyclopedia of Philosophy notes in http://plato.stanford.edu/entries/intrinsic-extrinsic/, there is wide disagreement on the precise definition of "intrinsic" and "extrinsic" beyond familiar examples from physics like "mass" and "density". And as far as I'm aware, no major ontology or ontology language supports this distinction.
In summary, I have two concerns. First, I'm concerned that this property and "extrinsic property" will exist be but under-researched and under-defined, and end up causing substantial community confusion like, say, member of (P463). Second, I am concerned that this property is far-reaching yet unconventional in the Semantic Web. Emw (talk) 01:51, 29 May 2014 (UTC)

  Oppose for the moment at least. You did not fill the domain and range (allowed values) in the template, though you imply them:
  • The range sounds far to big with cloths, colors etc. I guess we should have a properties each for colors, cloths and so on. To me, subporperties sound better. Such a property would not have much meaning, used in qualifiers to describe paintings this might be enough, but I'd like to use more general solutions:
  • The domain is far to small. We can take the same property to describe a thing in reality and fiction/arts. We do not need a property "shown with features" in addition to "wearing", "colour" and such properties for real things and perhaps even an property "described with features" for literature!? It will probably be better to describe fictional and real things with the same properties.
And let us first of all see how other formal description frameworks for visual works handle this. Or do you yet know similar solutions? Regards, --Marsupium (talk) 13:47, 19 January 2014 (UTC)
@Marsupium:. I had not thought of literature, but I agree it may be useful there too. At to what exactly we should do, I cannot think of any practical alternative. If we want to go into subproperies, it might get really complicated.
The only website I know supporting something like this is Joconde, and it is just as unspecific as what I propose [12] . Other databases only use a few very general values for their "depict" properties, and this is what is suggested in CONA. But of course, they cannot be as specific as we can, because they do not have like us millions of items about notables people, places etc. ;). --Zolo (talk) 18:19, 15 February 2014 (UTC)
Thanks for pinging me! And thanks for your comment. I think that we have to work out another solution. Especially because of what you pointed out with your last phrase. But if you really need this property for any purpose I do not want to be an obstacle during my absence on WD ;). So I gladly recall my opposition on condition that we may later replace it by other properties and delete it if we agreed on an eventually better model for the description of objects in images. However, I'd probably prefer the use of properties like color (P462) (Cave! The colour of – say – an oil painting may be different from the colour of an object depicted by the corresponding position of the oil painting since the image may show the object in a special light!), "shown with other object" (superclass of wearing), busy with activity and the like.
Best regards, --Marsupium (talk) 14:53, 19 February 2014 (UTC)
P.S.: You might also examine the model of Iconclass (Q1502787): http://www.iconclass.nl/contents-of-iconclass – though it is quite messy as far as I remember. I plan a more general examination on formal models for the description of images (CONA etc.) anyway, but I won't begin before spring and perhaps considerably later. --Marsupium (talk) 14:53, 19 February 2014 (UTC)

@Micru, Filceolaire: I don't agree we need lots of properties for that. This seems to be the right level of genericity : we know it applies to some artistic representation, photography or artworks. There is a very big number of things in a very big number of situations. This thing/situation or properties are pairs of item value which can precisely define the subject, and the types of this item will gives us the nature of this feature. IMHO we got all the information we might want in a flexible way, we don't need a ton of specific properties for each cases, at least until we got a more precise idea of the problems to solve.

Bibcode is similar to CODEN (P1159), for a different discipline. It would be good for the bibcode bot to be able to use Wikidata as its data store, making it easier to add new values as journals change series or new journals arrive. This was proposed to be added to English Wikipedia at w:Template talk:Infobox journal#ADS bibcode. I suggested at Property_talk:P819#Use_on_journals that it might be appropriate to reuse that property for journals, but I think a separate property is more appropriate. John Vandenberg (talk) 14:59, 7 March 2014 (UTC)

  Comment sorry my missing answer here. What is the difference between ADS bibcode (P819) and this new property? --Paperoastro (talk) 20:53, 9 March 2014 (UTC)
Hi User:Paperoastro. This property will have a different set of values, it will be allowed on periodicals instead of articles, and it has a different format - CeMDA instead of YYYYCeMDA..... When people see a ADS bibcode (P819), they will expect it is an article which can be accessed using that bibcode. This proposal for a bibcode reference code will only uniquely identifies a periodical. John Vandenberg (talk) 23:44, 9 March 2014 (UTC)
I understand your proposal, but when I query here, the result is always in the format YYYYCeMDA... See for example this link. Where is the difference? --Paperoastro (talk) 22:19, 10 March 2014 (UTC)
The format of articles in the journal is YYYYCeMDA... The code for the journal is CeMDA. It is useful to have the journal code as a property if you wish to covert a textual citation into an article bibcode. e.g. if I have "Morais, M. H. M.; Namouni, F.; Retrograde resonance in the planar three-body problem, Celestial Mechanics and Dynamical Astronomy, Volume 117, Issue 4, pp.405-421", and I want to create a bibcode, then I need some way to look up "Celestial Mechanics and Dynamical Astronomy" and obtain CeMDA, so that I can create the string 2013CeMDA.117..405M. If we have this property, or someone suggests another property to store this string, I can lookup "Celestial Mechanics and Dynamical Astronomy" in wikidata, and obtain 'CeMDA' via a property. John Vandenberg (talk) 23:45, 10 March 2014 (UTC)
Ok, if I understand correctly, you would use publication date (P577), volume (P478), page(s) (P304), author (P50) and this new property to build the ADS bibcode. In this case, I
  Support this new property, but probably it is better to change the name, because this code (I suppose) exist only in ADS. --Paperoastro (talk) 14:18, 11 March 2014 (UTC) P.S.: a technical problem: exist a manner to know if the list of author in P50 is in the right order?
Offtopic, the 'C' in http://adsabs.harvard.edu/abs/2010CeMDA.106..197C is not mandatory; http://adsabs.harvard.edu/abs/2010CeMDA.106..197 also works. Regarding checking the order of authorship, I dont think we have any tool doing that yet, and the problem is much broader than bibcode. We could check our data against bibliographic databases like Crossref (Q5188229). John Vandenberg (talk) 05:38, 6 April 2014 (UTC)

EINs would be an authoritative point of reference for specific U.S. non-profit/company/corporation profiles. SERutherford (talk) 01:05, 7 April 2014 (UTC)

  Question: Would this field have stability issues? Don't a lot of organizations change their EINs whenever they reorganize? This didn't used to be be common, but it has been since the 1980s. It seems that this number would change out from under an item regularly enough that it could become outdated. Also, there may be arguments about which corporation a wiki page is really about; wiki company article subjects often tend to actually follow a business operation, not a legal corporation, when the subject comes up. Perhaps neither of these are reasons to reject the property, though; but if it's approved, there should probably be documentation to the effect that EIN shouldn't be applied to items that relate to more than 1 historic corporation (or it is obvious and uncontroversial what single series of corporations were the single "main" organization in series). – The preceding unsigned comment was added by Closeapple (talk • contribs) at 2014-04-26T19:57:37 (UTC).
  Comment: The issue of stability is a good point, but wouldn't be much different than the common practice of legal entities' changing their names over time as they reorganize (e.g., ChevronTexaco to Chevron Corporation (Q319642)) and is manageable. Also, a point regarding their stability, EINs are permanent once issued and cannot be reused once canceled (see: www.irs.gov/Businesses/Small-Businesses-&-Self-Employed/Canceling-an-EIN-Closing-Your-Account). -- SERutherford (talk) 21:46, 26 April 2014 (UTC)
I would ask that we better differentiate this to make it country specific or specific to the body, eg. US-EIN, or IRS-EIN. There is a whole world out there and disambiguating is necessary. Similarly, the other descriptive components are are more specific.  — billinghurst sDrewth 14:54, 6 May 2014 (UTC)
Maybe it should be FEIN if we use it; some state tax agencies in the U.S. have a so-called state "EIN" but I think it's always the FEIN unless one hasn't been issued for some obscure reason. (That reason would have to be very obscure, since any entity (including a person) having any employees, and any corporate body filing any federal tax forms, more or less requires an FEIN, even if the organization is filing as tax-exempt.) But what else would EIN or FEIN mean as a property, that would make it ambiguous? We don't normally prefix other properties with their countries, do we? Isn't that what the property description is for? --Closeapple (talk) 17:47, 6 May 2014 (UTC)
This not a item, it is a property and proposed as "Employer Identification Number", not EIN. We don't have "authority control"s, we have specific, and nowhere else do you see any duplication of a property name, so please be specific. Otherwise we end with a string of US-dominated strings, so disambiguate a property now.  — billinghurst sDrewth 14:29, 9 May 2014 (UTC)

Unfortunately not. It seems that Berlin has its own system for its districts and suburbs. --Srittau (talk) 23:45, 27 April 2014 (UTC)
Two digits for districts, two more for suburbs (AGS for anything "Berlin" is 11000000?). I have the impression that there is a uniform scheme all municipalities in Germany have agreed upon ("Gemeindeteilschlüssel", [13]). To construct appropriate subdivisions is the responsibility of the respective municipalities, therefore there is no general meaning apart from "level-1 subdivision" and "level-2 subdivision". However for purposes of destatis the municipalities do not have freedom to enumerate them in arbitrary form. -- Gymel (talk) 00:20, 28 April 2014 (UTC)

  Comment: It seems that this is limited to exactly 12 Wikipedia items, already known, and the code is not duplicated or helpful for grouping the items in any way. Sometimes a unique code for only a dozen items might still be useful: There are probably some codes on Wikidata for admin-1 level divisions of specific countries with very few items at the admin-1 level. (I don't know which, though.) But I think there needs to be some evidence that this code might be the link to some useful information somewhere. Does some significant data use this number, rather than using the "AGS" or "Gemeindeteilschlüssel" mentioned above? --Closeapple (talk) 18:09, 6 May 2014 (UTC)

According to de:Liste_der_Bezirke_und_Ortsteile_Berlins there exist 96 Ortsteile within the 12 districts (four digits, the first two of them reflect the district number of the proposal above), and they are not to be confused with the 95 statistical subdistricts with three-digit-numbers (I probably have confused them already in my comment to the property above). It should be explained for what purpose these Ortsteilnummern might be of use, IMHO it usually suffices to have items for all entities and not to give an arbitray, albeit official numbering. -- Gymel (talk) 11:38, 30 April 2014 (UTC)

An open, authoritative identifier with good worldwide coverage for all corporate entities is needed to cross-reference statements about corporations. This is complementary to Legal Entity Identifier (P1278), because Legal Entity Identifiers are still in the process of standardization and won't have decent worldwide coverage for many years. OpenCorporates identifiers are based on jurisdiction and the company number issued by the corporate registry, and are completely open. An identifier also provides a cross reference to the actively managed corpus of open corporate metadata on OpenCorporates.com. Gangle (talk) 10:55, 13 May 2014 (UTC)

@Micru: - I thought adding this by hand should work well (There aren't that many articles about projections). The data would just serve as general information querying. For example if I am looking for the type of map projections used in Sweden I would get the information from the example. A long term goal would be to categorize the historic and official maps on Commons with this property. And even farther in the future we might have a database of every map ever made by an official institute, with the correct metadata attached to it. Tobias1984 (talk) 14:36, 29 April 2014 (UTC)
@Tobias1984: I am testing a new property assessment method, according to it:
  • previous or requested use in MW projects: 0 (or at least I don't know about it)

      • Yann, sorry that I didn't notify you, I thought you would check. Why do you need a property to link with the category, when it is already in the sitelinks here Category:École pratique des hautes études (Q13355080)? Perhaps I missed something?--Micru (talk) 10:49, 15 June 2014 (UTC)
        • @Micru: It is necessary in a case like Q668 (India). We have link with "Commons category": India, and we could have similarly "Wikisource category": India. We don't have a page on Wikisource called India, so we can't link Wikisource that way. It will be necessary to create interprojects links (Wikipedia article India to Wikisource category India). Regards, Yann (talk) 21:12, 17 June 2014 (UTC)
          • @Yann, tbh the "Commons category" property is redundant. The proper way to do it would be to use "topic's main category" to get the category item, and then from that item extract the sitelink to the category in wikisource. We already had the same discussion for Commons, and as far as remember that was the general consensus, to link categories with categories, pages with pages, and when some cross linking is necessary then use category's main topic (P301)/topic's main category (P910), to allow access to the other sitelinks. That won't work now (because of the missing aleatory access), but it seems counterproductive to create properties to link with each category of sister projects for something that is better done with a Lua script.--Micru (talk) 08:08, 19 June 2014 (UTC)
            • @Micru: Well, right now, the Commons category is useful. It allows interwiki links on Commons. Seeing that the deployment takes time, I only care about what works now, not what might work in an undefined future. Yann (talk) 18:33, 22 June 2014 (UTC)

This would be limited to personal professional partnerships, hence domain person (not organization). There is no need to include co-workers, this can already be determined, to some extent, using the employer property, along with dates. This is needed in order to claim a direct relationship between sportspersons, especially. Perhaps, it could be limited to sports partner, for now, because that's easy to define.

  Comment Jack the Ripper is not such a good example! It's an unsolved case. Also, this needs to be more specific than just "victims", and possibly more than one property is needed, e.g. for "possible victims". Danrok (talk) 03:30, 8 March 2014 (UTC)

Proposed byEmw (talk)

This property would enable military casualty classifications like killed in action (KIA), missing in action (MIA) and died of wounds (DOW / DWRIA) for military personnel. This property is complementary to cause of death (P509) (cause of death) and manner of death (P1196) (manner of death). It is different from those properties because it A) accounts for non-fatal casualties, B) is only applicable for military personnel in active service at the time of the casualty, and C) often has different granularity. This proposal arises from a discussion in Wikidata:Project_chat#Military_units (permalink). Emw (talk) 02:29, 12 May 2014 (UTC)
