I think it's needed and useful; we could use qualifiers to distinguish between different code versions. Ricordisamoa 20:09, 20 April 2013 (UTC)[reply]

Should we use qualifiers or simply imply the code version? --Ricordisamoa 22:51, 2 May 2013 (UTC)[reply]
I think we must use qualifiers, maybe the begin\end date of validity (when will be available the DataType), or the code version. --β16 - (talk) 08:10, 3 May 2013 (UTC)[reply]
  •  Oppose there are many different cadasters, its have different domains, different formats and etc. Mixing all cadasters in single property is bad idea. This makes the property usage difficult. But  Support creating "Italian new catastal code" property. — Ivan A. Krestinin (talk) 14:29, 23 July 2013 (UTC)[reply]

Traces the origin of separating organizations in other organizations. Jfhutson (talk) 14:23, 4 May 2013 (UTC)[reply]

Can this be achieved with the existing part of (P361) property and date qualifiers like until? For example, 'Presbyterian Church in America' part of 'Presbyterian Church in the United States' until (date of separation)? Emw (talk) 17:28, 4 May 2013 (UTC)[reply]
The PCA did not exist until it separated. It was founded because of disagreements between individuals within the church, so those individuals formed a new body. --Jfhutson (talk) 17:55, 4 May 2013 (UTC)[reply]
Good point. The basic semantics of this property -- part of something separating into something new -- seem applicable well beyond religious schisms. It seems like it could easily cover events like forks in software development, seccession (like South Sudan separating from Sudan), and likely other types of branching splits. Emw (talk) 18:46, 4 May 2013 (UTC)[reply]

There are many cases where such forks are well-documented, and this will allow us to automatically construct graphs (visual or otherwise) of the lineage. It would also be a good use case for qualifiers (date forked) when they are available. Superm401 - Talk 07:43, 4 April 2013 (UTC)[reply]

It might be appropriate to reuse based on ("the work(s) used as basis for subject") for this. I'm not sure, and that isn't well-documented. Superm401 - Talk 07:49, 4 April 2013 (UTC)[reply]
  • This property seems useful, but I would suggest that it's applicable in other domains, and thus should be crafted to be more generic. This relationship seems like a high-level genealogical description that could apply to evolutionary descent, historical linguistics, population migration, and historical splits in world religions and political movements and parties. The different domains use different idioms, but they seem to describe the same underlying thing. Emw (talk) 04:13, 10 April 2013 (UTC)[reply]
    Although I agree that evolutionary descent, population dynamics, etc. are similar/analogous to "forked from" in some ways, I think that's too broad. I have a couple possible updated proposals:
    1. Use a qualifier for based on (P144), e.g. "derivative work". I think "based on" is too vague without qualifiers; it could mean anything from "inpisred by" to "reimplementation of" (e.g. the GNU system is a cleanroom re-implementation of UNIX ("based on" in one sense), but not a derivative work of it). A qualifier makes "based on" more useful.
    2. Have a separate broader property than "forked from", but not so broad as the above. Perhaps, "derived from copyrighted work".
    Everyone, let me know what you think (I tend towards preferring the qualifier approach now that they're available), and if you prefer I make a new proposal, I can do that. Superm401 - Talk 02:53, 27 May 2013 (UTC)[reply]

   Not done
Descriptioncitations and quotes of Authors and other Works.
Data typeItem
Domainbooks, but maybe can be extended at every Creative Work (citations are commons in Movies too).
Allowed valuesIn the Books, domain, we could start with Authors and Works. I'm not sure if we want to use this for quotes as well.
SourceIt is a property form (I mapped it here).
Proposed byAubrey (talk)

It would be very useful to store the chapter/page/section of the citing work. I can say, for example, that Hamlet cites the bible (bad example, I know), but like this is not useful. With qulifiers, we could say that the First act of Hamlet cites the third cchapter of the Genesis, which I think is something worth saving.

In it.source, we have 2 templates that could map this property: AutoreCitato and TestoCitato (cited author and cited text). These templates make a wikilink from the cited author/text to his/its wikisource page, and also create a category which stores all the pages in which the author/text has been cited (ex. s:it:Categoria:Testi in cui è citato Dante Alighieri). --Aubrey (talk) 16:05, 1 June 2013 (UTC)[reply]

  • Symbol wait.svg Wait I think it is better to wait until the book data model is more developed and the people more used to it.

Data typeItem
Allowed valuesindividuals, groups, or schools of thought
ExampleFort Roughs → country: <Principality of Sealand → according to: Paddy Roy Bates>; <United Kingdom → according to: Government of the United Kingdom>
Proposed by — PinkAmpers&(Je vous invite à me parler)

One of the founding principles of Wikidata is that we need to be able to represent multiple divergent points of view without declaring any individual one to be correct. As such, we need a property essentially saying "this group/person claims such-and-such". "Stated in" only makes sense for creative works, and "imported from" only makes sense with other databases and the like. This will be useful for all sorts of complicated or contested issues, such as border disputes, competing scientific theories, or definition-related disagreements. — PinkAmpers&(Je vous invite à me parler) 15:54, 31 May 2013 (UTC)[reply]

 Oppose If you source with the newspaper article, the official report of an organisation, an TV/radio emission according to Help:sources you don't need this property which doesn't provide any possibility to check if the affirmation is correct. Snipre (talk) 17:52, 31 May 2013 (UTC)[reply]
But we don't need to check if the claim is correct. That's what ranks will be for. And no, a reliable source stating that Paddy Bates claimed sovereignty over Sealand doesn't constitute a TV station stating that he actually held such sovereignty. (In fact, journalistic/academic objectivity would prohibit any reliable source from saying such a thing.) — PinkAmpers&(Je vous invite à me parler) 06:14, 2 June 2013 (UTC)[reply]
If we want to say: Senkaku Islands is part of Japan according to Japan and part of China according to Japan, could arguably be expressed by "Senkaku Island. part of Japan. stated in: some japanese sources. etc." But still that may not be extremely clear. So agree that we need something, but I think it should be used as a qualifier, not in a source. (part of Japan, according to: Japanese government, source: text that says that it is the Japanese position).
This is related to Wikidata:Property proposal/Generic#Truth value. We apparently need a RFC on those things. --Zolo (talk) 07:05, 2 June 2013 (UTC)[reply]

    Proposed bySilkyShark (talk) 00:51, 8 June 2013 (UTC)[reply]


    What's the reason for this proposal? What should we do with this database id? How to use it? To source something? Regarding plants the provided information is very unreliable. --Succu (talk) 21:04, 8 June 2013 (UTC)[reply]
    It identifies the 'data item', giving us a way to use other references and making sure that all references are for the same species, it also does give reference information, in my opinion the reliability of all taxo info seems to be depending on which field you are in, some databases are considered the correct for animals, or one type of animals and wrong for plants, mushrooms, algae, bacteria and so on and vice versa. I think that wikidata should refer to them all. SilkyShark (talk) 03:38, 9 June 2013 (UTC)[reply]
    I also see the problem that ITIS is quite outdated (most squamta entries are as of 1996). However, ITIS is huge and in contrast to many other databases in the public domain and all data is accessible. Thus, we could use it as a basis for referencing all those basic things like species A in genus B if both, A and B have still the same name. Also it can be used as the basis for authors and year of description claims as these do not change in most cases. However, I would not add new items based on ITIS or even add claims if others exist.  — Felix Reimann (talk) 19:50, 25 June 2013 (UTC)[reply]
    ITIS is good source when you don't have any other source for taxonomy. I wouldn't use it for bot runs, or at least not in specific things. But I think it could be used to add higher than family taxonomic ranks. I don't know if it is good argument but getting ITIS link from wikidata helps making new articles and using it as rough source for taxonomy. Linnea (talk) 20:08, 3 July 2013 (UTC)[reply]

    Correct: we have to create an new item for all element representing the concept of the elements and then as instance of this new item all items describing the isotopes (just a small correction the current item for helium is in reality helium-2 item for sitelinks point of view).

    Motivation. Support point in time (P585) can be misinterpreted. For example if we have a population figure for 2009 then point in time (P585) should be used as a qualifier to identify the year the population was measured. point in time (P585) 2009.

    •  Oppose – Use point in time (P585) instead. It is not ambiguous. If used as a qualifier for a claim, it tells when the claim is valid. If used as part of a source, it dates the source. (PS. the wording "qualifier for sources" in the proposal a wrong. Sources do not have qualifiers. Only claims have qualifiers). Byrial (talk) 14:42, 8 June 2013 (UTC). PPS. If only one "as of" property exists, you cannot select the wrong one. If two such properties exist, there is always the possibility that the wrong one is used. Therefore it is better NOT to create a secong one. Byrial (talk) 14:48, 8 June 2013 (UTC)[reply]
    •  Oppose There is no possible misinterpretion: point in time (P585) as qualifier of a statement concerns the statement's value and point in time (P585) applied in the source section refers to the source.

    @Byrial and Sniper: That does make sense. --Tobias1984 (talk) 16:18, 8 June 2013 (UTC)[reply]
    The ambiguity is not date retrieved vs date of validity of the claim, it is between various dates that can apply to the source itself.

    Yes, but there is no guarantee that users will use publication date (P577) to mean "date of publication" rather than "date retrieved". And really if I saw just one date, I would tend to think it means "date of publication". And if I saw "date of publication: 2005, date: 2007", I would open my eyes in bewilderment. --Zolo (talk) 16:33, 8 June 2013 (UTC)[reply]
    Possible solution: Different labels for properties when used as statement or source-qualifier. --Tobias1984 (talk) 16:39, 8 June 2013 (UTC)[reply]
    What Zolo says do make sense, but the proposal as it is now (both text and the motivation) does not, as sources and qualifiers are different things which cannot be mistaken for each other. If the proposal is rewritten along the lines of Zolo's argumentation, I may support it. As the proposal is now, it does not make sense, and I have to oppose. Byrial (talk) 17:11, 8 June 2013 (UTC)[reply]
    It is true that my support does not really match the description of this property, nor the initial motivation. I think that the use of the word "qualifier" was a terminological mistake, as is shown by the mention @Filceolaire, can I change the description in the template from "qualifier for source statements" to as "property to be used in the 'reference' part of a statement"  ?
    The problem with that is that 'date retrieved' won't be used in a primary source statement (The wikidata page template in english uses 'source' not 'reference' for these statements so that is what I've called them). It will be used to qualify a 'stated in' database source or a web site source property so I think 'qualifier for source statements' is the right term.. Filceolaire (talk) 21:01, 8 June 2013 (UTC)[reply]
    "Statement" is the term used in WD:Glossary. It is not used in item pages themselves, so that it is a bit confusing, but still they are not qualifiers are there is no softwarewise hierarchy between properties in the reference field. I think we can simply say "to be used in the source field". --Zolo (talk) 05:11, 9 June 2013 (UTC)[reply]
    Changed to 'used in the source field for online sources' though I think there is a hierarchy for properties in the sources between the property you enter when you click 'source' and the properties you enter later by clicking 'add'. Filceolaire (talk) 08:09, 9 June 2013 (UTC)[reply]
    @Zolo I can imagine a population figure where the population property has the qualifier 'as of' 2009 to tell us what year the census was carried out and the source for this has a 'publication date' 2010 for the date the hard copy was published and a second source, for the online version of the same info, has a 'date retrieved' 6 June, 2013. Each of these date properties have different meanings and I don't think any of them can be combined without creating confusion. Filceolaire (talk) 21:01, 8 June 2013 (UTC)[reply]
    @Zolo. Don't add complexity by mixing database and document. If you have a document, the date of publication is enough, no access date is required and I would say no access date is relevant. When access date is necessary ? When the data origin is not static and no normal way exists to track changes in the source. So you can have only one date for source, date of publication or as of for date access, if you have 2, one is unecessary and has to be deleted.
    And be coherent: if you are afraid that people don't use the correct property between date of publication and as of, how do you want to offer a simpler system by adding a new property ? Snipre (talk) 17:39, 8 June 2013 (UTC)[reply]
    I would also think that in many cases the accessdates is not very interesting, but things are not always as clear cut as database entries vs scholarly articles. The access date is provided for most quality content in Wikipedia, for all types of online sources. It is documented in all examples provided in the documentation en:template:cite web, one of Wikipedia's most used templates. We can't discount that on a vague feeling that is is not useful.
    I do not expect to eliminate errors by adding a new property, but it will make them easier to detect. The confusion is much more likely between publication date (P577) and point in time (P585) than between publication date (P577) and "date retrieved" (all the more as "as of" cannot be translated exactly in all languages). If we have a "date retrieved" property, we will not need point in time (P585) in the reference field, so that we can detect it as a likely error. We cannot do that if we use "as of" for "date retrieved". --Zolo (talk) 18:45, 8 June 2013 (UTC)[reply]
    Domain description amended as proposal below. Filceolaire (talk) 22:23, 9 June 2013 (UTC)[reply]
    @Zolo. I am not so sure: for all hard documents you will have a publication date and no contributor will add twice the publication date property with two different dates: he will understand the problem and will look for a better property. For online database there is no publication date so considering the action of adding a data in wikidata as a publication of the data seems for me very strange. But contributors will definitively use point in time (P585) so they will be aware of that property so what is the differentce of point in time (P585) as qualifer and "date retrieved" for sources ? I agree that the sense "date retrieved" is a little better but in the other sense you add a new property leading to more choices and this will increase the number of wrong choices statistically speaking. Snipre (talk) 12:03, 10 June 2013 (UTC)[reply]
    I think people will sometimes use point in time (P585) to mean date of publication, especially if it is renamed from "as of" to "date" which seems necessary because "as of" does not really mean "date something took place". Granted, using separate items for metadata about the source itself should make things more manageable, but still I would be surprised if we do not encounter this problem, and I do not think a separate "date retrieved" property would make anything substantially more complex. --Zolo (talk) 15:40, 10 June 2013 (UTC)[reply]

    ExampleOpeth (Q18557) => Mikael Åkerfeldt (Q450285)
    Proposed byMicru (talk)

    Motivation: There is no generic property for "members of organizations" only specific ones like P100 (P100), cast member (P161), member of sports team (P54) and member of political party (P102). Eventually this property could be combined with the proposed property "as", providing greater flexibility instead of having to create specific properties every time.

     Support --Nightwish62 (talk) 22:35, 13 August 2013 (UTC)[reply]
     Support good for Template:Constraint:Inverse. Also: At least P100 (P100) will be deleted and replaced with member of (P463). We have too many "member of something" properties.PfD member states. --Tobias1984 (talk) 07:08, 14 August 2013 (UTC)[reply]
     Oppose I do not think cast member (P161) should be replaced with a "has member" property (it may be possible to use a more general property than P161 with qualifiers, but am not sure that cast members can really be considered "members" of a movie). member of sports team (P54) and member of political party (P102) can probably be replaced with member of (P463), but not with a "has member" property, as they work the other way around. We could decide that it should be supplemented with the reciprocal "has member" but I do not see much use for that, and I think we should try to avoid properties that require hundreds of values for a single item (the Chinese Communist Party probably has thousands of members in Wikidata...). --Zolo (talk) 07:54, 14 August 2013 (UTC)[reply]
    Is your opposition regarding the substitution of p161 only, or also against the creation of the property for other uses? I agree with you and with FelixReimann's comment below that this property should be only for complete lists of members whenever it makes sense.--Micru (talk) 12:19, 14 August 2013 (UTC)[reply]
    It is also against other uses. Restricting its use for complete list sounds sort of appealing but I do not think it is realistic and Wikidata's data-structure does not seem to be really suited for that. We can only source and qualify individual statements, not a set of statements using a particular property, so taht we cannt state "this list is complete according to X". Things may become messy if different sources conflict or when the list changes over time. Actually we have rather similar issues with has part or parts (P527). --Zolo (talk) 16:22, 14 August 2013 (UTC)[reply]
    Would it be better if I propose a specific property for bands?--Micru (talk) 05:05, 15 August 2013 (UTC)[reply]

      It's your main field of studies. You don't have to add a minor if it doesn't exist in the curriculum, or there's no such explicit destinction. I mean if someone studies computer science, it is "computer science". If someone studies geography, it is "geography". While university systems are different in many countries, any student has a main subject or "major". You could probably rename it to "field of studies" (or German "Studienfach"), but I'm not sure that would be the better naming. The terms "major" and "minor" are used in English-speaking countries, and the corresponding "Hauptfach/Nebenfach" are common in human sciences in Germany as well.--Kompakt (talk) 13:53, 2 August 2013 (UTC)[reply]

If it is intended to be a property for claims of a state, then the label should be changed to 'observer of' (as a partner to the existing 'member of' property), and the description should be more clear, such as 'international organization that the subject organization has observer status with' or some such wording.Joshbaumgartner (talk) 10:48, 9 May 2013 (UTC)[reply]
     Oppose - P100 (P100) is going to be deleted (Wikidata:Properties_for_deletion#member_states_.28P100.29). It would be better to have a qualifier for member of (P463) that says "type of membership". Example:
    • State A
    • type of membership = observing state (qualifier)
    • start time = 1950 (qualifier)
    • end time = 2004 (qualifier)
    • type of membership = full membership (qualifier)
    • start time = 2004 (qualifier)
    • State B
    • type of membership = full membership (qualifier)
    We should archive this proposal and start a discussion about a qualifier. --Tobias1984 (talk) 11:35, 3 August 2013 (UTC)[reply]
    No need for a new property. 'instance of' will work well for this qualifier:
    • State A

      • I think it would also be possible to use this property in a more general way, like Riksdagshuset is related to Sveriges riksdag as an example, ie not only for churches/tempels etc... The object in this case should always be an article about architecture, and the subject related to an organisation of some kind. I guess these articles are often merged, but not always. We have hundred of articles about churces and parishes on svwp, they are not so often merged. -- Lavallen (block) 06:50, 20 April 2013 (UTC)[reply]
    I think it could be useful to also have a prperty for an image of the building, for the same purpose as above. In the building-article, the general image-property can be used, but this is for a more specific purpose in the organisation-article. -- Lavallen (block) 08:52, 20 April 2013 (UTC)[reply]
    "place of assembly" or "venue" might work as property labels too. I wouldn't mind having several properties though. The image you mention would go on the item about the building. --  Docu at 21:50, 21 April 2013 (UTC)[reply]
    Your correct, it's better to add an image-property to the architecture-item. -- Lavallen (block) 07:03, 29 April 2013 (UTC)[reply]
    •  Oppose This property seems redundant with part of (P361). If a particular place of worship is part of a secularly-defined or ecclesiastically-defined area, then 'part of' P361 could capture that information. Places of worship within an area could be separated from other parts of an area by having a query select only parts of the area that are an instance of a place of worship. This approach would allow for varying levels of precision, e.g. instances of any given type of venue in any given type of organization, where the type of venue and type of organization are simply query parameters. Emw (talk) 04:08, 25 April 2013 (UTC)[reply]
      • this property would be for the organization, not the building. "Part of" could only work the other way round. --  Docu  at 09:18, 25 April 2013 (UTC)[reply]
    • My point is that this sort of domain-specific information can be better captured with generic properties. An inverse property of "part of" -- e.g. "has part" -- is easily envisionable, and would capture this information while also putting the part-whole claim on the 'whole' (the organization) rather than the 'part' (the building). Having a proliferation of domain-specific properties will raise the barrier to entry for users trying to learn how to find things. Using fewer, but more expressive, generic properties to capture this information as explained above would allow users find items that match what they're looking for much more easily. Emw (talk) 12:13, 25 April 2013 (UTC)[reply]
    • "has part" suggests ownership .. with your suggestion, you'd need a qualifier to define the nature of the part. Essentially, this would lead to two properties being needed for the same. --  Docu  at 05:02, 29 April 2013 (UTC)[reply]
    • Huh? How does saying "X has part Y" imply "X owns Y"? I don't see how that's the case. Saying 'China part of Asia' does not imply that Asia "owns" China, nor would 'Asia has part China'. Other relevant examples are at the bottom of Help:Basic_membership_properties: 'has part' would simply swap the subjects and objects of each claim there, and not introduce the implication of ownership between those items. Emw (talk) 11:59, 29 April 2013 (UTC)[reply]
    • I see the point of 'has part-property' even if it isn't created yet as far as I understand. But it looks to me like we still need a qualifier-property to describe what kind of part it is! --Lavallen (block) 12:44, 29 April 2013 (UTC)[reply]
    • What do you mean, precisely? One interpretation is that we need to know what kind of thing the subject is. That problem is solved by instance of (P31) and subclass of (P279) --having a proliferation of 'part of' properties for each different type of entity is unsustainable. Another interpretation is that we need to know what meaning of "part of" is intended. I think that's a reasonable concern. We likely need better semantics to describe precisely what kind of "part" something is. There's an ongoing discussion about that at Property_talk:P361#Neutrons. Emw(talk) 02:32, 30 April 2013 (UTC)[reply]
    • One of my problems with "instance of" is that it does not make sense to translate it. In English it means everything, but in Swedish it means nothing. It sounds like something a politician would say, a nice looking part of semantic, with no substance. But if you tell me that '"has part" "Gudmundrå kyrka" ("instance of" "church")' is correct, it's fine with me. It does not have to be beautifull, it just have to work. And I saw the talk at "Property_talk:P361" yesterday and it feels like centuries I studied predicate logic, so I abstain from participating there. -- Lavallen(block) 05:27, 30 April 2013 (UTC)[reply]
    • Your problem with "instance of" seems to be with its colloquial usage, which is indeed often nebulous as you say. However, the instance of (P31) property is based onrdf:type, and thus isn't some meaningless phrase, but rather a fundamental tool for classification recommended for the Semantic Web by the W3C. It's used ontokens (instances) to describe what type (class) they are a member of.Emw (talk) 19:00, 5 May 2013 (UTC)[reply]

     Oppose. I think 'part of' can be used to link items to their place of worship. This is used to indicate you are 'part of' a congregation. Filceolaire (talk) 09:10, 18 August 2013 (UTC)  Not done currently no support for creation. --Tobias1984 (talk) 19:39, 24 August 2013 (UTC)[reply]

    Proposed byTCN7JM 02:53, 7 August 2013 (UTC)[reply]

    I believe a property is needed to portray the affiliation of hundreds of teams in minor leagues of sports to their major league affiliates. Past affiliates could be shown using the start and end date qualifiers. TCN7JM 02:53, 7 August 2013 (UTC)[reply]

    • Pictogram voting comment.svg Comment could you expand on the description a little more what "affiliation" encompasses. With such a wording people are going to use it all over Wikidata. How will it work outside of sports? --Tobias1984 (talk) 07:25, 7 August 2013 (UTC)[reply]
      Hmm. Perhaps "affiliated with" may not have been the best wording. I think the wording I was really looking for was "parent club". I've changed the title and the description to match this. TCN7JM 11:21, 7 August 2013 (UTC)[reply]
    • Pictogram voting comment.svg Comment Sorry but I think 'Parent club' is much too specific. 'affiliated with' is better. Examples where this can be used outside sport include:
    'Union' affiliated with 'political party'
    'Political action Committee' affiliated with 'political party'
    'local boy scout troop' affiliated with 'local church'
    'Wikimedia UK' affiliated with 'Wikimedia Foundation'
    It is similar to 'member of' but used for links between two organisations and anywhere the relationship is not called 'membership'.
    It is not used for links to things like 'Atheism' or 'Vegetarianism' where there is no formal organisation you can point to. (In those cases use 'instance of' 'atheist' or 'vegetarian'.) Filceolaire (talk) 15:30, 18 August 2013 (UTC)[reply]

    • Pictogram voting comment.svg Comment You use datatype string, but your example links to an item. It also need another time qualifier because most holidays are pretty recent inventions.

    I'm sorry, it wasn't supposed to use string datatype but item datatype, I'll change. The exception that I was talking about was the time qualifier for mobile festivities. Because they are mobile, we can't say when they are celebrated. - Sarilho1 (talk) 13:49, 15 August 2013 (UTC)[reply]
    This property will link to all public holidays celebrated in a place but doesn't identify which holiday is the particular holiday associated with that place. Most countries have a particular holiday they identify as their national holiday (July 4 in the USA, St Patricks day in Ireland). In some countries every village has their own special day. Should we just have a qualifier for the "type" of holiday? Filceolaire (talk) 20:17, 15 August 2013 (UTC)[reply]
    I suppose we could have qualifier 'instance of' 'national holiday'; 'local holiday'; 'public holiday'; 'bank holiday'. Filceolaire (talk) 20:30, 15 August 2013 (UTC)[reply]
    Normally, in the item's page it should have a statement saying where it is celebrated (symmetrical property), so there won't be lack of information. Anyway, I think it could be used a qualifier to do it, if needed. - Sarilho1 (talk) 20:55, 15 August 2013 (UTC)[reply]

    Aren't you making it even more complicated now? National Day of Sweden (Q1348730) is a banking day in Sweden, it has official recognition, but it is not celebrated to any recognized degree, if you do not happen to be at a place the royal family is visiting at that very day.

    I guess we are talking about official celebrations, that must be confirmed, probably, by a constitution. So, I prefer my propose, because we can say which holidays have place in some location, including internationals celebrations, like Christmas. - Sarilho1 (talk) 18:52, 16 August 2013 (UTC)[reply]
    We have items like Christmas in Japan, why not try to do something around them? -- Lavallentalk(block) 19:11, 16 August 2013 (UTC)[reply]
    That's the problem. It's a unofficial celebration, so these property become useless. In all over the world there are celebrated unofficial public holidays. If we want to use this property, we just can use it to official celebrations. - Sarilho1 (talk) 20:42, 16 August 2013 (UTC)[reply]
    All celebrations are unofficial, even Christmas in the country I live. If you are working on these holidays or not is a matter between the employer and employee. (Except for banks who follow special rules.) From my point of view, any kind of item can be attached to this kind of property, even "Ramadan in Greenland". Then you can add "instance of public holiday" or not to any of those items together with other properties describing their importance. -- Lavallentalk(block) 12:24, 17 August 2013 (UTC)[reply]

Maybe "Holiday/festivity in administrative unit". Note "public holidays" could also have been used on the item of the holiday itself. Maybe it's better to have a distinct property for that. --  Docu  at 07:13, 24 August 2013 (UTC)[reply]

     Oppose as per Snipre. Danrok (talk) 22:13, 27 August 2013 (UTC)[reply]

    Note that we have public holiday proposed above this one. Festivities may be a bit problematic, unlike public holidays, there is not necessarily an official list.

    Proposed byJeblad (talk) 15:59, 21 June 2013 (UTC)[reply]

    The intended behavior is to follow Wikidata:Property_proposal/Pending#URL/Website to the site, get the content and then optionally extract a fragment of content with an Xpath-statement, and then check if Property:P387 (quote) can be found within this content. If there is no quote available the check is against the actual value in the statement, and then the match must be more accurate.

    It can work together with other parts of a reference to automate verification of a statement, but only the previous two are planned for inclusion in an extension. It should be possible to use it as an ordinary property, even without the extension, and it should be possible to write gadgets that does the same thing as the extension, but they will make the perceived speed of the site significantly slower.

    This property does not need to be available before some time, that is the URL property must be available for this property to be usable. Jeblad (talk) 15:59, 21 June 2013 (UTC)[reply]

    day in year for periodic occurrence

    Data typeItem
    Allowed valuesitems allowing calculation of date, such as en:Category:Days of the year or more specific ones that might still need creation, e.g. first Sunday in May (Q14582865)
    It's just maths, which can be coded in programs. Here's the some formula for working out the date for Easter: Calculating the Date of Easter. It would be bad practice to look up a date in a data table, when it can be calculated. Calculating it means the answer can always be found - not possible with data because time is endless and data isn't. Danrok (talk) 12:10, 31 August 2013 (UTC)[reply]

    We have items for each day of the year. We have items for each day of the arabic year (and articles for these in Arabic and Farsi). We need to create articles for "first sunday in May" and all the other similar days. These should have properties specifying the day of the week and the earliest and latest day of the year. That should define them.
    We also need items for all the days from Mardi Gras to Easter Monday, whose timing is tied to Easter, each with a statement of how many days before Easter Sunday they should be. For the timing of Easter Sunday we need an item for the 'Spring Equinox', an item for the 'first Full moon after the spring equinox' and Easter is the Sunday after that.Filceolaire (talk) 21:18, 31 August 2013 (UTC)[reply]
    • "We need to create articles for "first sunday in May" and all the other similar days.": Agree, let's create them when needed.
      "These should have properties specifying the day of the week and the earliest and latest day of the year.": Not sure about this. I think either we should defined the frequency in a standardized format (e.g. "1*5:1:7" mentioned above) or leave it to parsing the label "First Sunday in May".
      For Easter related days occurrences, it would be good to have items such as "Easter + 10 days". --  Docu  at 21:01, 1 September 2013 (UTC)[reply]

    Proposed byMicru (talk)

    Motivation: Some items don't have meaning on their own because they are extensions of a main item. They are usually connected in Wikipedia using Template:Main (Q6797933). I was wondering if it would make sense to reproduce this kind of relationship in Wikidata like William Shakespeare (Q692) <has subitem/subitem of> Shakespeare's life (Q8018307), or Finland (Q33) <has subitem/subitem of> history of Finland (Q202808).

    •  Support  – The preceding unsigned comment was added by King jakob c 2 (talk • contribs).
    •  Oppose the connection is in my opinion so general, that we might as well not make it. I don't think anybody is going to query something like "I want to know all subitems that can be assigned to William Shakespeare (Q692)" --Tobias1984 (talk) 05:56, 14 August 2013 (UTC)[reply]
      Not that query, but for instance it might be useful for visualizers (like Reasonator), to show which other items contain links to useful Wikipedia articles or connections to related Commons categories.--Micru (talk) 12:14, 14 August 2013 (UTC)[reply]
      There is a relation between these items which we should represent, especially as some WPs will include the subitem information in the main article, instead of making it a separate article. This property seems a good way to represent this relation. If, for instance, all economic statistics are on the 'economy of' subitem page. Filceolaire (talk) 03:44, 15 August 2013 (UTC)[reply]
    •  Oppose The relation is based on particular articles of some wikipedias and are not an universal relation: we have to avoid to import specific classification of some wikipedias in wikidata. 10:11, 14 August 2013 (UTC)[reply]
      history of the United States (Q131110) has 57 language versions. I wouldn't call that "a specific classification"...--Micru (talk) 12:14, 14 August 2013 (UTC)[reply]
      Wouah, an example and you do a general case. How many country articles follow this rule ? And if you wait 10 years you will get a History of the economy in US article. There is the category tool in wikipedia to solve this problem and this is the best tool because this tool is specific to each wikipedia as the splitting of subjects between the different articles. Snipre (talk) 12:57, 15 August 2013 (UTC)[reply]
      There are many more examples and I'm sure you are able to find them too. It doesn't matter if the item divisions are specific to a language, you can do the query for the langugage you are interested in, and then you get the articles related. Another option could be to use "main topic" to describe orphan items.--Micru (talk) 17:27, 15 August 2013 (UTC)[reply]
      Yes, there are many examples but I know the reasons of the creation of the existence of articles like History of XXX: this is just because of the main article of XXX was too long and splitting the article in different new articles for readability reasons. But this is completly arbitrary and dependent on the policy of each wikipedia. And finally what is the criterion to allow the link with the property has subitem / subitem of ? Can I create a link World war II has subitem Adolf Hitler ? There is a strong connection, I hope you agree. And know can I link Catholic church has subitem Galileo ? The Galileo case is strongly connected to Catholic church. Washington DC has subitem George Washington ? And for Russia has subitem Catherine The Great ? Italia has subitem pizza ? There is no limits so this will be a mess because you can through this property link what you want if you think there is a connection. Snipre (talk) 12:30, 24 August 2013 (UTC)[reply]
      Snipre: In 10 years the categories will have been replaced by wikidata queries because the category tool is much too blunt an instrument. Our job is to come up with a way of classifying the various items and wikipedia pages so the wikidata query tool can find what the user is looking for. This property will be useful in establishing the link between these pages. If you can think of a better way to describe the relationship between these pages then please feel free to do so. For example we could rename "Main Category topic" to "Main topic" - see comment by Micru above. Would you prefer that? Personally I prefer the current proposal.

    We already have OpenStreetMap relation ID (P402). While it is much more easy to handle, it can only point to a specific type of object in openstreetmap (Relation). Also internal IDs within opensteetmapare not intended to be linked on as they are not stable links to semantical objects. IDs may be replaced in osm if the objects are refined. A very common way to query openstreetmap data is the so called Overpass API using Permanent IDs which is, in fact a query (and not an ID). But since openstreetmap data is in permanent flow, this is also a more stable way to get data from osm. Don't get me wrong: I still want to keep OpenStreetMap relation ID (P402) because I think its simpler and in many cases its stable enough for entities like countries or buildings. But the Permanent-ID is more established and recommended by the openstreetmap community. provides a nice interface to experiment with. any questions? opinions?--Shisma (talk) 09:49, 12 August 2013 (UTC)[reply]

Observe that this does not always affect the Swedish label, since the English or German transliteration may have become more used in Swedish than the correct Swedish transliteration. Also observe that latin-latin transliterations exists, for example between English and Latvian. This can maybe instead be solved with another datatype. -- Lavallentalk(block) 12:25, 20 August 2013 (UTC)[reply]
    •  Oppose. What Lavallen said, plus consider that multiple romanization systems may exist even for the same pair of languages. Take a look at this, for example—for Russian alone a dozen system of romanization exist, all of which are used in English to some extent. The property need to be more specific to be useful, and definitely more than one is needed.—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); August 20, 2013; 18:44 (UTC)

    •  Oppose the examples are about the same chemical, but they are not about the same subject. Ascorbic acid in an organism is not the same thing as ascorbic acid in a beaker. Also I think the scope of this property is not a single semantic concept. Being something and 'having been' something are just to distinct for example. --Tobias1984 (talk) 07:06, 21 August 2013 (UTC)[reply]
    Tobias: I'm not sure I understand what you are saying. How would you describe the relationship between vitamin C (Q199678) and DL-ascorbic acid (Q193598)?
    How are the properties of Ascorbic acid in an organism different from ascorbic acid in a beaker? Should they have different items? Filceolaire (talk) 14:02, 21 August 2013 (UTC)[reply]
    To me a similar example would be to merge the item for "car" with the item for "car accident". The properties of the car don't change but they are expressed in a different situation. A somewhat clumsy link would be: DL-ascorbic acid (Q193598) = "pharmaceutical/biological properties (described in)" = vitamin C (Q199678). --Tobias1984 (talk) 14:17, 21 August 2013 (UTC)[reply]
    I think I see what you mean. DL-ascorbic acid (Q193598) is a chemical compound. vitamin C (Q199678) is a collection of pharmaceutical/biological effects which can be caused by DL-ascorbic acid (Q193598) and other related compounds. Is that it?
    This suggests the relation is sort of like DL-ascorbic acid (Q193598) instance of (P31) vitamin C (Q199678) but not quite. Filceolaire (talk) 15:09, 21 August 2013 (UTC)[reply]
    No. said to be the same as (P460) is for things that are widely thought to be the same as but they aren't or it is disputed. Filceolaire (talk) 15:09, 21 August 2013 (UTC)[reply]
    You can also use said to be the same as (P460) with status "deprecated" or with "start-end date" for the period that it was thought to be the same.--Micru (talk) 18:26, 21 August 2013 (UTC)[reply]
     Oppose On the basis that as far as I can see, the examples given are not exactly the same thing. From the article "Ascorbic acid is one form ("vitamer") of vitamin C". That suggests to me that, possibly, ascorbic acid is a subclass of vitamin C. Danrok (talk) 15:10, 27 August 2013 (UTC)[reply]

    •  Oppose I don't think taking dollars as reference point is a good idea. It hasn't been around for most of human history and it might be difficult to source the exchange rate for currencies that have no economic connection to the dollar (probably up to the 20th century). I think we should go with gold as our reference point because that can be sourced to the beginning of currencies and we can calculate the modern dollar to euro value e.g. from the cost of 1 kg of gold in euro and in dollar. --Tobias1984 (talk) 10:50, 25 August 2013 (UTC)[reply]
    Tobias that is a good suggestion regarding the relevance of gold throughout history. The reason for USD being the central reference is that we live in a fiat currency system currently based around the federal reserve. Plus we are not longer on the gold standard. A commodities property proposal section is needed. Thanks for the suggestion, this is a philosophical economic question honestly.Mcnabber091 (talk) 04:26, 26 August 2013 (UTC)[reply]
    In my opinion economics is pure philosophy :) If this property really needs to be in dollars I suggest naming it "exchange rate to U.S. dollar". It will need time qualifiers for the time this exchange rate was valid. Probably also a place qualifier. The price of one dollar probably varies depending on the country and bank you visit. To keep data coherency we should go with a more or less stable source. --Tobias1984 (talk) 06:12, 26 August 2013 (UTC)[reply]
    While the foreign exchange markets currently us the dollar as their universal yardstick that has not always been the case and may not always be the case in future. This property can be used to show the exchange rate to any currency by changing the number dimension. I would oppose changing the name from "Exchange rate".
    While having a "Price per kilo" property, to show the cost of gold and other commodities, sounds like a good idea it hardly seems like a reason to oppose this property. Can you change that Tobias? Filceolaire (talk) 14:27, 26 August 2013 (UTC)[reply]
    The situation is far more complex than having a single exchange rate property. There are many types of exchange rates which are constantly changing. I don't think we will be storing minute-by-minute rates any time soon, but we could consider storing monthly rates, in which case there's still more than one original source. Here's an example source BIS effective exchange rate indices. If monthly is too frequent, we could just store quarterly rates, or even just annual rates (e.g. December's rate). Danrok (talk) 15:27, 3 September 2013 (UTC)[reply]
    Symbol oppose vote oversat.svg Strong oppose for being US Dollar specific. Use qualifiers as for example: Exchange rate (qualifier instance of (P31): United States dollar (Q4917)): 4,50. Or use and wait for datatype number with unit.  Oppose for the property as a whole: The exchange rate to whatever changes continuously. If this property is created, why shouldn't someone update the property by adding a new value every single second? I do not think that datatype number is designed to hold continuously changing values.  — Felix Reimann (talk) 17:05, 3 September 2013 (UTC)[reply]
