Pictogram voting comment.svg Comment: This is an incomplete proposal. The only unique content is the description, and the French version seems to mean something slightly different than the English version. Both seem to have something to do with association under the French law of 1901 (Q11513034) but I don't know what, and my native language is English. The rest of the proposal is just template messages: no examples, and no discussion of motivation. --Closeapple (talk) 07:07, 25 October 2014 (UTC)[reply]

Motivation: We need this property to express the election periodOursana (talk) 11:21, 15 October 2014 (UTC)[reply]

Do we need a way to clarify cases like the U.S. House of Representatives in the U.S., where there are elections every 2 years, but the term of office is 6 years, because only 1/3 of seats are up for re-election each time? Or en:Cambridge City Council where "Elections for a third of the seats take place 3 out of every 4 years" ? -- Jheald (talk) 16:22, 15 October 2014 (UTC)[reply]
strong yes, but first we have to install the general property for hundreds or thousands of parliaments in the world and their different election periods, because also in your example we need this property, and then use qualifier with applies to part (P518) 1/3 or 33 %--Oursana (talk) 22:03, 24 October 2014 (UTC)[reply]

Proposed bySweet kate (talk)

With founded by (P112) being limited to the domain of person (Q215627), there's no current way I see to indicate when something was founded by an organization. Lots of schools are founded by religious organizations, new non-profits are organized by other non-profits, foundations are chartered by social groups, etc. Unless someone has a better idea? Sweet kate (talk) 22:30, 24 November 2014 (UTC)[reply]

 Support Very useful also for hospitals: Haydom Lutheran Hospital (Q15838483) => Norwegian Lutheran Mission (Q1770870). It might be good to at least discuss a domain change for founded by (P112). --Tobias1984 (talk) 09:14, 25 November 2014 (UTC)[reply]
 Oppose Use founded by (P112). Snipre (talk) 13:53, 25 November 2014 (UTC)[reply]
 Oppose Same as Snipre. --Casper Tinan (talk) 14:08, 25 November 2014 (UTC)[reply]
Then as Tobias1984 says, we need a domain change for founded by (P112). How do we make that happen? (I was using founded by (P112) and it was telling me it was a constraint violation, which is why I requested this property.) Sweet kate (talk) 14:58, 25 November 2014 (UTC)[reply]
@Sweet kate: I just checked, and the constraint template can't handle or-relationships at the moment Template:Constraint:Value_type. I think we will just have to ignore the constraint violations until the template can handle this. Maybe User:Ivan A. Krestinin has a better idea? --Tobias1984 (talk) 15:17, 25 November 2014 (UTC)[reply]
There are technical ways to resolve this. But I am not sure that relations person -> organization and organization -> organization are the same type of relations. founded by (P112) is used already in 4 templates in ruwiki and in unknown number of templates in other wikies. Are you sure that these infoboxes are ready to display organizations too? Labels and another context of these infoboxes can conflict with organizations. It is more simple to split two properties in infobox than filter single property. Also difficult cases can present with organization was founded by some person, but some organization is legal and financial founder. So I think more accurate way is creating new property, so  Support. — Ivan A. Krestinin (talk) 19:41, 25 November 2014 (UTC)[reply]
@Snipre:, @Casper Tinan:, given Ivan A. Krestinin's feedback, any additional thoughts? Sweet kate (talk) 21:57, 8 January 2015 (UTC)[reply]
No, we have to change the constraints. For me they are no problems because we can filter and differentiate person from organizations using P31. From concept point of view there is no reasons to differentiate persons and organizations in term of fondation. Snipre (talk) 10:06, 16 January 2015 (UTC)[reply]
I cannot see in what way the Founder-foundation relation could differ depending on the nature of the founder. As the concept is the same, there is no reason for creating a duplicate property.Casper Tinan (talk) 10:32, 16 January 2015 (UTC)[reply]
 Oppose the constraint on founded by (P112) should be changed to juridical person (Q155076) and that would allow both people and organizations to be founders of other organizations Apohllo (talk) 00:34, 16 January 2015 (UTC)[reply]

Case definitions for infectious conditions under public health surveillance (US CDC, 1997) provides definitions for various case definitions used in epidemiology. In the scope of Wikidata, number confirmed, number probable and number suspected seem relevant. These would be used as qualifiers on number of cases claims.

The WHO and CDC provide case definitions for outbreaks and uses these for reporting, e.g., The coarser number of cases (proposed above) is typically used by mass media, but more granular figures are also of interest in comprehensive coverage. Emw (talk) 03:55, 31 October 2014 (UTC)[reply]

 Support. Filceolaire (talk) 23:25, 2 November 2014 (UTC)[reply]
 Support Wikidata should store information from reliable sources about particular disease outbreaks. This data is especially useful when particular Wikipedia articles cover those diseases. The paper "Case definitions for infectious conditions under public health surveillance" is a good idea for defining what characteristics of disease outbreaks should be measured and quantified, and what the numbers presented mean. When this kind of information is available it seems reasonable to put it in Wikidata because this is the sort of information which could be called in multiple Wikimedia projects.

Proposed byFilceolaire (talk)

This is so that we can identify where one property is the inverse of another property. For Symmetric properties the object can be the same as the subject as the second example above. This is different from the Constraint as in most cases we will not be requiring that there is always a statement using the reverse property wherever the property is used. Filceolaire (talk) 17:36, 13 November 2014 (UTC)[reply]

I've updated the property to note it implements owl:inverseOf, not owl:InverseFunctionalProperty, per Vladimir's comment below.
  •  Oppose Oppose Have to agree with @Snipre: owl:inverseOf just creates redundant triples.
    • Since you can query a relation in any direction (in WDQ, in a SPARQL triple pattern, even in a SPARQL property path), inverses are never necessary
    • An entity with many incoming relations (eg Germany) will also get a lot of outgoing relations, and its RDF file (to be served out of the entity URL when one of the RDF mime types is requested) may become too large. That's why in the Getty vocabularies LOD we decided to eliminate downward properties.
    • Read the judicious reasons why the PROV ontology has no inverses. And even more: reserves the names of potential inverse properties. Wikidata might adopt such practice, but DO NOT create pairs of inverse properties!
    • @Emw: owl:inverseOf has nothing to do with owl:InverseFunctionalProperty. IFP is used for stuff like "if two people have the same SSN then they are the same person". --Vladimir Alexiev (talk) 02:45, 23 December 2014 (UTC)[reply]
Vladimir, thanks for the correction regarding owl:inverseOf and owl:InverseFunctionalProperty, and for the pointers to PROV-O and the Getty Vocabularies. Given that other major vocabularies like the Relation Ontology (RO) use inverse properties and owl:inverseOf is a widely used feature per, it's not immediately clear to me that inverse of would be a bad idea. I'll need to read around more, but those resources you are good to have on hand. Emw (talk) 08:14, 23 December 2014 (UTC)[reply]
User:Emw, I work for a semantic repository vendor, so I can only say "the more triples the better" ;-). But you should consider the consequences. If you create Q an inverse property of P, then both props will get used. Then the RDF export either has to materialize all pairs xPy and yQx, or leave it to a reasoner or repo to do the inverse inferencing, or burden the user with seeking both patterns ?x P ?y and ?y Q ?x in queries. Which is exactly what PROV wants to avoid.
The right approach is not to omit an inverse declaration, but NOT to create Q in the first place: you don't need redundant properties. --Vladimir Alexiev (talk) 09:01, 23 December 2014 (UTC)[reply]
@Vladimir Alexiev, Snipre: This proposal is about creating the "inverseOf" property, not choosing if we should have properties that are inverse of others. It's a point that is more important than the creation of this property and should maybe be the topic of a WD:RFC. As there are currently some properties that are inverse of an other, do you agree to the creation of an "inverseOf" property in order to manage them (property that may be removed when we will get free of properties that are "inverseOf" others if there is a community consensus about it)? Tpt (talk) 10:30, 23 December 2014 (UTC)[reply]
 Support @Tpt: if inverseOf will be clearly described as a book-keeping property, used to "seek and destroy" actual inverses; with a reference to the PROV considerations given above. What I oppose is to make automatic inferencing for inverse and symmetric properties, which I've seen elsewhere in a request

Some properties are transitive i.e. if A => B and B => C then A => C. Others are not. This allows us to specify for each property which case applies. This property can also be used for any other boolean properties/characteristics. Knowing whether or not a property is transitive will mean will mean we know whether or not we can follow a property up the chain. Filceolaire (talk) 17:53, 13 November 2014 (UTC)[reply]

I have created several special items to fulfill this structural need:
For example, the OWL spec notes that "in mereology, the partOf relation is defined to be transitive, reflexive, and antisymmetric". We should model this like so:
part of (P361)
Emw (talk) 14:52, 19 December 2014 (UTC)[reply]
Note: apparently OWL considers asymmetric and antisymmetric properties to be the same. seems to contradict that. I'm rusty on my logic and don't have time at the moment to investigate that further. In any case, we should not be going outside OWL in these kinds of statements, so I've updated the 'part of' example above to use 'asymmetric' rather than 'antisymmetric'. We should merge Q18647520 into asymmetric Wikidata property (Q18647519) if 'antisymmetric' is conflated with 'asymmetric' in OWL. Emw (talk) 15:01, 19 December 2014 (UTC)[reply]
  • "Comply with semantic web standards" sounds right and mighty, but the fact is that there's modest RDFS inferencing on the real semantic web, and very little OWL inferencing. In general, we should not introduce property characteristics before the Wikidata community fully understands the implications of RDFS & OWL inferencing. The horrible class hierarchy shows that the community does not understand even the implications of rdfs:subClassOf. --Vladimir Alexiev (talk) 03:14, 23 December 2014 (UTC)[reply]

Vladimir Alexiev, thanks for those summaries. I agree that Wikidatans should be made aware of the definition and implications of these property characteristics. At the same time, I think we should support these Semantic Web standards from OWL 2 DL in Wikidata, even if certain technologies like Ontotext's GraphDB may not.
User:Emw, I never said GraphDB does not support them (in fact it supports them more efficiently than many competing products). I'm only making wikipedians aware of what these mean in terms of inference. (Please don't talk of "OWL DL": OWL2 has 3 more profiles: EL, RL and QL, that are just as important as DL. Talk of "OWL2".)
Vladimir, referring to "OWL 2 DL" is entirely reasonable and done in many reliable sources. Including the "2" makes sense because OWL 1 DL doesn't include several major features of OWL 2 DL, e.g. punning. Including the "DL" makes sense because it distinguishes the referrent from OWL Full. As noted in Section 10 of the OWL 2 Primer, all OWL 2 EL, RL and QL reasoners are also OWL 2 DL reasoners, but OWL 2 DL is tuned for a more general set of cases. So if we want to talk about the current decidable subset of OWL without getting into the weeds of the various more specific profiles -- as I think we often do when discussing modeling issues on Wikidata -- the way to do so is by referring to "OWL 2 DL". And if we're being persnickety, then it should be "OWL 2" not "OWL2", as most reliable sources use the spaced styling. Emw (talk) 16:13, 24 December 2014 (UTC)[reply]
@Emw: "Decidable" is not the same as "decidable in a reasonable amount of time". RL, QL, EL have many benefits compared to DL, which itself has benefits compared to Full, that's why W3C bothered to define RL, QL, EL in OWL2. It's not the time and place to decide on any sort of commitment that Wikidata may have towards DL, RL, QL, EL, that's why I suggest you don't refer to DL specifically, refer just to "OWL 2". Vladimir Alexiev (talk) 14:08, 25 December 2014 (UTC), corrected on 7 Jan 2015.[reply]
Major ontologies use owl:ReflexiveProperty and owl:TransitiveProperty. The OWL 2 recommendation outlines stories for these features in Use Case #5, Use Case #6 and Use Case #8. See Simple part-whole relations in OWL Ontologies by Rector et al. and Relations in Biomedical Ontologies (RO) by Smith et al. for descriptions of how part of (P361) is transitive, reflexive and asymmetric. RO is a foundation in many natural science ontologies. So we do indeed want a way to represent owl:ReflexiveProperty, for example.
Transitivity is no doubt needed. But consider again what I wrote about owl:ReflexiveProperty above (local reflexivity = self-restriction is another story, see below). I think we need stronger practical (actual) examples of what it's useful for. RDFS and OWL also define a bunch of properties to be reflexive, including rdfs:subClassOf and rdfs:subPropertyOf. But I cannot think of any practical use for this reflexivity: can you?
You said: "owl:ReflexiveProperty P means xPx for every item x. You don't want that, believe me!"? The description is helpful but neither that in itself nor the vague warning is a compelling argument against encoding reflexivity in property statements. Regarding their usefulness, see the use cases linked in the comment you're replying to, and the discussions of part of in the linked papers. Emw (talk) 16:13, 24 December 2014 (UTC)[reply]
This is not a vague warning, but a very real consequence of using reflexive properties. If you declare such owl:ReflexiveProperty for some props and export the ontology to RDF & OWL, complying repositories have to to make these inferences. For example, "x rdfs:subClassOf x" and "p rdfs:subPropertyOf p" for every class and property. And speaking from experience, these are always useless. If you want to declare part of as reflexive, then for each item you must make the reflexive claim (at least for items falling in its domain), else the property is violated. In other words, interpreting part of as proper part of is more sensible and useful. Vladimir Alexiev (talk) 14:08, 25 December 2014 (UTC)[reply]
I am wary of tying Wikidata's vocabulary to seemingly custom, proprietary features like step properties used in only one particular software product.
Likewise I think we should avoid defining "real" Semantic Web inferencing in a way that excludes significant RDFS and OWL inferencing engines like, say, ELK, Pellet, Racer and FaCT and ontologies that use owl:TransitiveProperty like those in the OBO Foundry.
I never said to exclude TransitiveProperty (just gave a better construct that ties step & transitive). I don't understand how you concluded that "step properties" is a feature of our product. It's a very basic concept: many transitive properties feed off (are declared as superproperties of) a step property. Example from wikidata: "member of" is the step property of "part of". Example from SKOS: skos:broader is the step property of skos:broaderTransitive. RDFS is amiss not to declare such, so both of the most popular RDF APIs do it: Sesame (sesame:directSubClassOf, sesame:directSubPropertyOf and sesame:directType) and Jena.
I concluded that step properties were a feature of your software because the link in your previous comment ("See this Ontotext GraphDB performance hint") links to a section titled "TransitiveProperty Through Step Property". The fact that that's a subsection of "Consider Specialized Property Constructs" (emphasis mine) and returns no clearly applicable results suggests that "step property" is a non-standard term with no (or little) use beyond your Ontotext product. It's discussed in the context of a "transitiveOver" property construct, which is also non-standard. The optimization technique may well be useful, but in my opinion the proper place to discuss supporting it is a W3C mailing list, e.g. or rather than a project that strives for compatibility with current Semantic Web standards.
You concluded wrong. These are suggestions and ideas how to implement a transitive property more efficiently by declaring which is its step property. They are not "ontologies" nor features of GraphDB. They are not limited to GraphDB: the same considerations apply to any reasoner.
The basic idea of Semantic Web is openness: anyone is free to create new constructs (and it's no coincidence that all RDFS and OWL constructs are expressed in RDF, i.e. the schema and data are expressed using the same data model). If Wikidata adopts a construct like "p transitiveOver q", that will allow more efficient reasoning with transitive properties, and at the same time can be exported using the standard construct Vladimir Alexiev (talk) 14:08, 25 December 2014 (UTC)[reply]
 p ptop:transitiveOver q.
 q rdfs:subProperty of p.
 p owl:TransitiveProperty.
That said, if you could convince Markus Krötzsch that Wikidata should support step properties as you suggest, then I would probably support your proposal. Otherwise, I think we can use standard techniques to achieve something like step properties. For example, part of (P361) would have the statement "instance of (P31) transitive property (Q18647515)" and member of (P463) could be made a "step property" by the claim "member of subproperty of (P1647) part of". Property transitivity is not inherited via subproperty of to my understanding, so member of would thus be a non-transitive step property of part of by those straightfoward, standards-compliant techniques. Emw (talk) 16:13, 24 December 2014 (UTC)[reply]
In my page above I also write that "subPropertyOf" could be used to declare the step property, HOWEVER that's not fully robust. The reasoner also needs a "promise" that the transitive property won't be asserted explicitly (ad-hoc). If not, transitiveOver will miss to make some part of the closure, since it seeks to extend the path only using the step prop, not the transitive prop (that's what makes the reasoning faster). I think this matches best-practice usage: editors will only claim member of whereas some reasoning mechanism will infer part of as the closure of member. Vladimir Alexiev (talk) 14:08, 25 December 2014 (UTC)[reply]
I agree that Wikidata's class hierarchy is messy, particularly towards the top. I would say that derives at least as much from differences in philosophical perspective as misunderstanding of the implications of rdfs:subClassOf (subclass of (P279)). We could clean up our class hierarachy by importing a well-known upper ontology like, say, BFO, but I think that's a separate discussion. For now I think educating the Wikidata community on basic things like "what is a reflexive property?", etc. in an easy-to-understand way would greatly help.
I hope we won't have to go the BFO or DOLCE way, IMHO it's too abstract for most people.
The main reasons are: 1. there's no editorial control over "subclass of" (which is just as important as property definition), 2. No editorial control over "instance of" (which is non-transitive and a critical point: no classes below this point admitted). 3. No clarity what's "design" vs what's a "physical item", something that FRBR addressed 10-15 years ago for Works. @Emw: Could you please help me start a RFD on this important topic?
BFO, DOLCE, SUMO etc. are easy to crudely simplify to everyday terms (s/continuant/object, s/occurrent/event, etc.) and they provide a robust ontological framework for representing knowledge. They are also used in many of the world's major scientific ontologies, e.g. Gene Ontology and other OBO Foundry ontologies.
BFO at least has a clear way to discuss "design" vs. "physical item"; see the Information Artifact Ontology and its constituent Document Act Ontology (more). These are both considerably more comprehensive than FRBR as they take into account a broad range of knowledge describable via documentality. They also have the advantage of being coherently tied back to an upper ontology, and seeing use in many domain ontologies.
I don't see how your points 1 and 2 are arguments against importing an upper ontology like BFO. The fact that there is little active curation of the top of the hierarchy is as much an argument against having a hierarchy as it is an argument against having an imported upper hierarchy -- both would be subject to uninformed editors adding mistaken claims and making the hierarchy a mess. Same with your comment on instance of; how it is specifically an argument against importing an upper ontology like BFO is unclear. And your "no classes below this point admitted" comment warrants refinement: Wikidata is replete with metamodeling, where classes are classified with instance of and have many classes below them via asserted subclass of claims.
I'm not arguing against BFO, I said I hope we won't have to go to such levels since they're complex. I very much doubt your claim "they're easy to simplify". I think it'll take real ontologists to figure out how to apply it to Wikidata, and then a genius to cast it to practical terms that the wide editorial community can understand. Wikidata, IMHO, needs first and foremost practical solutions!). I've worked with data models for 20 years and ontologies for 4 years, but I'll admit without shame that I'm a little scared. I've read about BFO (in the context of VIVO), I'll read about IAO, DAO, documentality.

You ask about how we can represent owl:FunctionalProperty, owl:InverseFunctionalProperty and owl:propertyChainAxiom. Good question! We may be able to capture such knowledge in Wikidata property statements, but like universal and existential quantifier knowledge from owl:allValuesFrom and owl:someValuesFrom, I think Wikidata would need user interface enhancements to make those features understandable to non-specialists. Emw (talk) 07:41, 23 December 2014 (UTC)[reply]
Agree. Manchester Notation was discussed several times (eg Wikidata:Project chat/Archive/2013/07#Turtle vs. Manchester_syntax and Wikidata:Requests for comment/Typing : class ⇄ instance relationship in Wikidata. It is indeed the most readable notation for expressing OWL axiom, while Turtle is the most readable for expressing RDF data, and the two are equal for RDFS axioms. The Quick Reference gives examples for all OWL constructs (though not all examples correlate to each other). Eg here are some examples of self-irreflexivity and self-reflexivity I made up following that quick ref:
 Class: Person
   SubClassOf: not hates Self
 Class: Narcissist
   SubClassOf: Person
   SubClassOf: loves Self
 ObjectProperty: loves
   DisjointWith: hates

Pictogram voting comment.svg Comment However, it's not just about readability of syntax and making nice editing widgets. Wikidatians should also understand the possible inferencing (Open World) vs constraint/validation (Closed World) vs documentation interpretation of the selected constructs, pick an interpretation that's appropriate to the purpose (Wikidata being "LOD in the wild"), document it, and design appropriate editorial policies. The RDF Shapes working group was recently formed precisely because OWL2 semantics cannot be used for validation. Eg see this poll, User:Kcoyle is aware of it.

  • Nevertheless, OWL2 constructs can be used for validation, given appropriate interpretation (eg Pellet ICV)
  •  Support Overall I support using standard vocabs to document properties and classes in Wikipedia, if we are not tempted to blindly stick to OWL semantics without considering the consequences
  • BTW, the OWL vocabulary for classes is quite richer than the vocabulary for properties. We should use that too

@Filceolaire: Are there existing or pending property proposals for start/end dates for these yet? We can just change the datatype for this property to suit your preferences if you would like. The property itself is what's important, not the datatype that it has. TeleComNasSprVen (talk) 17:54, 27 February 2014 (UTC)[reply]
The Domain is the type of item that uses this property. From your description this is items about politicians. For these items we have position held (P39) for each office the politician is elected to. If they are elected 4 times to the same position then position held (P39) has 4 values, each with qualifiers of (P642) to indicate the city/state and start time (P580), end time (P582) for the dates. I don't think this property would add anything.
Well, if that person holds that position (continuously) for several consecutive terms, there might be only one value with start and end date spanning the whole period (i.e. POTUS for 8 years). The proposed property could serve as an additional qualifier explaining that these 8 years span 2 terms. -- Gymel (talk) 21:03, 24 February 2015 (UTC)[reply]

  •  Oppose: There is also cantor (Q330679). While en:Cantor (church) only mentions his responsibility for vocal music, de:Kantor emphasises that playing the organ is one of his usual duties as well as "Kantor" being the designation for the person in charge of all musical activities in the church. Anyway it would be a bit funny to denote the Thomaskantor (Q641457) Johann Sebastian Bach (Q1339) with this property as the employed organist (Q765778) of St. Thomas Church (Q170402). I think supplying the inverse property, i.e. noting employer (P108) at the person with the specific kind or denomination of tasks as a qualifier would be more exact. Questions like "who played the organ there" perhaps should be more appropriately answered by a (not yet existing) property for the indiviual organ items. -- Gymel (talk) 10:23, 15 June 2014 (UTC)[reply]
    • Cantor would not be appropriate for organists at secular venues. In the UK, churches may have a musical director "in charge of all musical activities", senior (or at least different) to the organist. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 08:40, 5 July 2014 (UTC)[reply]
      • I have to admit that I have no clue what your proposal is aiming at: Is the emphasis on "person employed to play the organ" (which then we deem more important than the musician in charge of everything)? Or is it rather "who played the organ?" (which I consider an appropriate property for the organ, not the church). The :en:infobox you mention has provisions for "organist/director of music", "organist", "organ scholar" and "director of music" (but not "cantor" - bias at work?) and seems to list all lay personell at the given church at the price of selectivity: Not a good supposition for transfering the parameters to wikidata, I think. Singling out the parameter "organist" necessitates a more stringent definition than implicit from the infobox context, therefore my question. -- Gymel (talk) 23:37, 14 July 2014 (UTC)[reply]

Proposed by: Runner1928 (talk)

Motivation: I have worked with US Department of Education data for several years. It is useful and high quality, though the trade-off is that it is often about a year old by the time it's published. IPEDS, the Integrated Postsecondary Education Data System, is a large dataset that, because it is created and published solely by the US federal government, is in the public domain. There are many, many properties for colleges in this data, but some that we might prioritize are:

  • number of students: undergraduate, graduate, ...
  • latitude/longitude location
  • graduation rate
  • faith affiliation
  • official website

But in order to map US colleges in Wikidata to Department of Education data, we must have IPEDS ID values in Wikidata. Then a bot can do the data transfer work. Runner1928 (talk) 21:27, 10 March 2015 (UTC)[reply]

Proposed byJheald (talk)

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

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

The most common type of such "auxiliary" items in categories are survey articles on the topic of the category as a whole, identified by category's main topic (P301). The second most common type of "auxiliary" item is a list paralleling the membership of the category. That is what this proposed property would identify.

Proposed byProgVal (talk)

This property could be useful for editors to not confuse concepts that are close to each other. For instance, one may see peering (Q772532) and think of it as a “political concept” instead of the actual meaning (the technical action of connecting networks). Having Q19400005 mentioned in the page would help distinguish these two concepts.

Moreover, this property could be used in infoboxes to show related (or “going further”) articles.

Proposed byHusky (talk)

When Googling for certain places, in the 'knowledge graph' box a list of 'points of interest' appears (see example), this sounds like a very valuable addition to Wikidata as well. A case could be made that this could be a combination of several different properties (e.g. monuments, parks, squares, etc.), but given that the types of POI's might be endless, and is very difficult to create ranking and filter such a list, i think a single property would be better. I thought about calling this 'touristic attraction', but 'point of interest' sounds a little bit more neutral. I could imagine this would be very useful for Wikivoyage as well. Husky (talk) 23:50, 20 December 2014 (UTC)[reply]

If there were just three POIs for Amsterdam, this might work. Otherwise, shouldn't this work the other way round: determine what are POI for your interest => select the ones that are located in Amsterdam. --- Jura 13:13, 21 December 2014 (UTC)[reply]
  • This seems to me to be inherently subjective. Each wikipedia could have a different opinion on which are the points of interest and each wikivoyage could have an opinion too. We have geolocation so we can find items that are near. We know stuff about each of those items so we can filter to just show museums or monuments or public transport infrastructure or whatever.

Note that it is sometimes a bit messy, because in Lua. For instance, because Lua redirects are not recognized as redirects by the software. Both en:Module:Location map/data/United States and en:Module:Location map/data/United States of America have an item though they are really the same module. This property could help make things a bit clearer, and should help with the maintenance of maps in Wikipedias.

I think the module should be limited to Lua data. In most Wikipedias, the same data are still stored in a Wikistyle template like Template:Location map USA2 (Q2885082). If we also need a property for this, I think it shold be a different one, as templates do not work the same way as modules, and are much harder to reuse. Zolo (talk) 13:16, 5 January 2015 (UTC)[reply]

  • Symbol oppose vote oversat.svg Strong oppose. @Zolo:I think this should be stored in Wikidata so that we no longer need any local location map modules. We can use it in any wikis without copying it. See my propose below.--GZWDer (talk) 13:19, 6 January 2015 (UTC)[reply]
That sounds like a good idea, but it can only works once arbitrary access is ensabled. There are also some ticky points. For example en:Module:Location map/data/USA only includes mainland USA while fr:Module:Carte/données/états-unis also includes Alaska and Hawai. Beside, the French module also contains some language-related data that do not seem really fit for Wikidata. Anoher case is Québec that two modules using different map projection techniques (fr:Module:Carte/données/québec and fr:Module:Carte/données/québec (conique).
There issues are solvable of course,but they suggest that things will not be very totally straightforward, and will require some work from the Wikipedia side. @GZWDer:, I support the poperty you propose below, but given the bleak track-record of most Wikipedias in terms of Wikidata incorporation, I still think of "location map data" property could be useful, at least the very least as a transitory measure, and I do not see any major issue with having that. --Zolo (talk) 14:24, 6 January 2015 (UTC)[reply]

Apparently, most of them are directly copied from enwiki, but rather few languages have the submodules that would be necessary to make it work. I guess it is up to individual Wikipedias to choose if they want to use data-modules or want to wait until they can somehow pull Lua functions directly from Wikidata items. --Zolo (talk) 17:09, 7 January 2015 (UTC)[reply]
 Oppose Lets do this once and do it right even if it takes a little longer. Store the data as statements on wikidata. The example you linked to does bother me as the coordinates quoted ignore Alaska, Hawaii and Puerto Rico. If these map parameters get added on wikidata it will be to an item labelled 'contiguous states of the USA' not to the USA item. Just saying. Filceolaire (talk) 19:56, 19 March 2015 (UTC)[reply]

What instead I think we need is a property that allows to connect two people (especially when one is mentioned often in relation to another). related properties (P1659) is IMO too generic, since I can link not only person but also his company, group, other abstract-concept related to the subject etc...

There's enough of a difference between publication date (P577) and this to warrant the latter's inclusion: a video (this may be an episode, a movie, or something on YouTube even) may have both an airdate, when it is first shown to the public, and a release date when one may acquire it in either a physical or digital form. Furthermore, many videos are often repackaged in compilations or anthologies, whose release dates may be contenders for the 'true' release date.

What about video games? The consensus so far I've seen in most Wikipedias is: "Title of video game in that Wikipedia language (original lang.: Tytuł oryginalny)". This is presented also in infoboxes (e.g. pl:Amnesia: Mroczny obłęd) as a separate row in the header. I understand that it's not so easy to implement in terms of how Wikidata allows you to translate all property values. For most games it would be sufficient to use English as an original title. However, there's a great number of games coming from Japan, and then some... Not sure if this would be something that Wikidata could fix, or we should fix on each Wikipedia separately.

In many ways, this is similar to the Dyntaxa ID proposed above. There is little or no original information, just a presentation of highlights as seen from a particular country. If we start this we will end up with a lot of these national databases (something like Bellis perennis may end up with dozens of these ID's as statements). In this particular case I am not impressed with the maps (not the actual distribution, but the states in which it occurs). - Brya (talk) 05:02, 16 February 2015 (UTC)[reply]
The paper Database of Vascular Plants of Canada (VASCAN): a community contributed taxonomic checklist of all vascular plants of Canada, Saint Pierre and Miquelon, and Greenland (2013) gives some background information. The data are released as CC0. --Succu (talk) 10:21, 16 February 2015 (UTC)[reply]
 Support I think it meets the quality requirements for out "identifier + link"-data. @Brya: I think dozens of statements is not even the beginning of what some items will likely have. In my opinion more a problem on the view and filter side of the database than on the data-side of the database. The interface will need to become smarter once we have hundreds or thousands of statements on single items. --Tobias1984 (talk) 10:31, 16 February 2015 (UTC)[reply]
The fact that I have mixed feelings does not mean I don't see some benefits as well. This would be a real database, easily managed. Having a lot of such databases entered into items (and there are quite a few of them!) would make it easy for the user to see what are the "good taxa" that are widely accepted. The fictitious taxa would stay bare of them. But still this means adding a lot of statements for very little real gain in information, a massive redundancy. Also, there would be a skewed effect: taxa in developed countries can be found in lots of databases, while taxa in undeveloped countries have no databases to be listed in. - Brya (talk) 11:44, 16 February 2015 (UTC)[reply]
I would rather have something with real information: we still do not have the e-flora's. - Brya (talk) 11:59, 16 February 2015 (UTC)[reply]
@Brya: That is exactly how I see it. The extra statements are a tradeoff between redundancy and some sort of measure of how established a name is in the literature (The latter with a lot of question marks, if the databases copy data between each other without any checks). The comment about developed countries is a lot more difficult and probably can't be solved intrinsically by Wikidata. It is kind of similar situation to the gender-bias (if it can even be called a bias) on Wikipedia and Wikidata. We can't write more about women, if none of our sources write more about women. So it is a bias of the worlds body of literature and not one of Wikipedia/Wikidata. At least in biology we know that the coverage-situation is improving (on a long time scale). --Tobias1984 (talk) 15:20, 17 February 2015 (UTC)[reply]
In the case of these official national databases, I am not worried about errors: these are to a high standard (the errors can be found in the ambitious world-wide aggregators, like the Catalogue of Life, The Plant List: in these the error rate is pretty much off the scale). But redundancy is an issue: if we adopt VASCAN ID we will also have to adopt the USDA Plants, and VASCAN ID will have little that is not in USDA Plants as well. This is a lot more pronounced in Europe, very likely there will be a French database, a Belgian database, a Dutch database, a British database, a German database, an Austrian database, etc). And, yes, coverage is increasing, even on a short time scale, it is just that garbage seems to be increasing at least as fast. . . - Brya (talk) 18:03, 17 February 2015 (UTC)[reply]
@Brya: Wikidata is all about "somebody says this", it's not up to us to decide whether or not it is an error. It's up to somebody who want to cross datas to decide whether or not it's a good information. Known errors are to be marked "deprecated", that's all. TomT0m (talk)
Ah, the phylosophy of "let's connect everything to everything else, making the biggest, most impenetrable, most error-riddled tangle imaginable". The purpose of Wikidata is to hold structured data based on reliable sources. It is the duty of users to decide what should and what should not be included; Wikidata is here to fight the connect-everything-to-everything-else-phylosophy and to keep out the junk. Marking known errors as "deprecated" proves to be very damaging and is quite insufficient. - Brya (talk) 17:34, 23 February 2015 (UTC)[reply]
Ah, your beautiful comments, formated god knows how (seems it's just done that way to annoy), and unproved claim ... Marking deprecated is the standard way to do in Wikidata. Can't you automatically track the differences beetween the databases ? Is'nt it just an ID property by the way ?

corresponding numerical code

   Not done
Descriptionqualifier for alpabetical codes containing the corresponding numerical value
Data typeString
Allowed values\d+
Exampleeuro (Q4916): ISO 4217 code (P498) => EUR (qualifier => 978)
English (Q1860): GOST 7.75–97 code (P278) => анг (qualifier => 45)

Many of the code systems have both alpha and numeric value for the same entity. There is the problem of entering these codes. In most cases, the code property includes only alphabetical code. And even if there is a separate property for a numeric code, is impossible to establish a correspondence between them. Sometimes code is entered as a string containing both alpha and numeric values, but it reduces the usability of such a value, it must be pre-processed every time before use. The proposed qualifier solves some of these problems. It's must be string, not numeric, because some codes have leading zeroes. —putnik 20:55, 20 March 2015 (UTC)[reply]

  •  Oppose I'd rather see a separate property. --- Jura 14:04, 24 March 2015 (UTC)[reply]
  •  Oppose Agree with Jura: there should be two props "ISO 4217 alphabetic code" and "ISO 4217 numeric code". Two reasons:
    • The chance that people would accurately enter the numberic code as proposed above, approximates zero
    • What matters is that RUR and 810 are obsolete (end time 1998), not so much that they correspond to each other

KulturNav ID

DescriptionThe ids as used by KulturNav, a common site for ontologies used within the cultural sector in Norway and Sweden.

Robot and gadget jobsManuel verification, but could use automatic updates.

Motivation: KulturNav is a common site for all kinds of ontologies used to describe the content in Norwegian and Swedish museums. Often this will map nicely to encyclopedic content in Wikipedia and then further onto Wikidata. Even if almost everything can be mapped to similar descriptions here, one type of mapping seems to me especially interesting and that is persons. A lot of persons that otherwise lacks good IDs given by an autority will be defined in this registry. Over time there will be a separate registry in Norway, the so called Historical person registry, but it will take time to make that an viable option. As most of the historical persons will be cultural persons already described in KulturNav we can speed up things and start building the connections with IDs from KulturNav.

There is a slight problem with how the entity and the dataset is separated. We can always use the UUID from the URL as the identifier, but this is strictly speaking for the dataset and not for the entity. Most datasets seems to have a fragment id #entity.alternativeId-0 and this as the full URL ( could be a valid URI for the entity. It doesn't seem to be available information about this, so it is perhaps better to say we have a seeAlso-like relation with the dataset until they can provide some documentation. Using the UUID is a bit fishy anyhow, so the philosophical problem isn't that important.
