Metadata properties

Read this first

If Semantic Web concepts like "range", "domain", "type", "Class", "subClassOf", "Property" and "subPropertyOf" are Chinese to you, I highly recommend reading:

The OWL 2 Primer explains those basic Semantic Web concepts. Once you've read that, use http://www.w3.org/TR/rdf-schema/#ch_properties as a reference for the definitions of "range", "domain", etc.

  • rdf:type and rdfs:subClassOf are probably not very relevant for statements on properties.
  • Range, domain and subproperty of are exceedingly relevant.

There are several more pieces of vocabulary relevant for statements on properties -- e.g. inverse of (owl:inverseOf) -- but I recommend understanding the basic properties first. Familiarity with them is essential for anyone discussing statements on properties. Emw (talk) 13:11, 14 November 2014 (UTC)

Properties for property domains

Properties used for:

  1. Specifying which items may bear a given property ("property domain")
  2. Specifying which values a given property may be assigned ("property value domain")

datatype item
links to a class-item (an item which subclass of and instance of properties link to). The property should (mostly) only be used on items which are an instance of (P31) of items which are subclasses of the class-item specified by this property.
matches the rdfs:domain property Filceolaire (talk) 18:06, 8 October 2013 (UTC)
Symbol support vote.svg Conditional support. I would support storing domain claims only if the semantics matched those of rdfs:domain. This implies constraints that can be leveraged by semantic reasoners to do type inference, as summarized in http://www.ksl.stanford.edu/software/jtp/doc/owl-reasoning.html. These are "strong" constraints. User:Silver_hr made some informative comments on this in W3C standards for property "domain" and "allowed values". Emw (talk) 15:56, 14 October 2013 (UTC)
@Emw : I doubt we can seriously align the semantics to those of owl like that, as we would have to ckeck the consistency of the whole wiki and of the database all the time. I'm pretty sure considering the size and perimeter of the database it would be kind of really hard, and that it would be all the time inconsistent, so anything could be logically deduced ... We need something weaker, and try to achive all ontology consistency and zero constraint violation with the tools we have. TomT0m (talk) 18:05, 14 October 2013 (UTC)
Having the definition of 'domain' match rdfs:domain is independent of how we ensure consistency in the knowledgebase. It simply means that for a property P that has the domain C, "resources denoted by the subjects of triples whose predicate is P are instances of the class C." Whether we want to prevent inconsistent statements though measures in the UI or simply detect inconsistent statements after the fact as we currently do is an independent matter -- we can still use rdfs:domain as the formal definition of 'domain'. Emw (talk) 19:36, 14 October 2013 (UTC)
Formal definitions in owl is useful if we want to prove that the onlogy is consistent and the datas are consistent. If there is inconsistencies, then by en:explosion principle then anything becomes virtually inferable, that makes inferences pretty useless, so we lose the advantages of having strong and well defined semantics. If a kitten can become a mayor, then we can't decently say the range of the mayor property is a subclass of human in those conditions. Or we need to make a special case in the ontology just for that, or to weaken the constraint insanely. That means if we do a owl export of that, the database will have to be badly curated before we actually can use it in a reasoner. TomT0m (talk) 20:23, 14 October 2013 (UTC)
Using rdfs:domain as the definition of domain does not in itself prove that the ontology is consistent. It simply provides one of multiple criteria to show that. Consistency enforcement is a distinct, independent matter, as explained above.
Furthermore, citing exceedingly rare counterexamples as a reason to abandon the idea of property domain and range constraints is in my opinion a red herring. First, we should ask ourselves if such counterexamples are actually valid. Can a kitten be a mayor, or can a horse be a senator? No, they can't -- by default, considering such things to be invalid subjects of properties conventionally restricted to humans is entirely reasonable. It is completely sensible to assert that kittens cannot be mayors. Second, if there is a compelling reason to expand the domain or range of properties beyond their conventional values, then we have a viable option in the case of crazy office holders or other subjects of properties conventionally restricted to humans: expand the domain from human (Q5) to person (Q215627). As described in the Wikipedia article Person, that term is quite the catch-all. Third, the fact that some properties might have unintuitively broad domains and ranges does not negate the fact that other properties actually do have well-defined domains and ranges. The domain of encodes (P688) is subclasses of gene (Q7187), and its range is subclasses of protein (Q8054) or RNA (Q11053). The statement no label (Q14862218) encodes (P688) kitten (Q147) is always wrong. Emw (talk) 22:05, 14 October 2013 (UTC)

Symbol support vote.svg Conditional support. As @Emw: mentions, encodes (P688) should have domain gene (Q7187) and range protein (Q8054). But there are hundreds of Wikipedia articles (and therefore Wikidata items) about both the gene (Q7187) and the protein (Q8054), for example BRCA2, DNA repair associated (Q421651). Therefore the property encodes (P688) points to the same item. This happens for many other items where the domain and range are conflated in common language (and in Wikipedia articles). I support Domain, but are we prepared make items on Wikidata separate, even when the domain and range are conflated in Wikipedia (or invent a new semantics of Domain for these cases)? Jefft0 (talk) 13:17, 29 November 2014 (UTC)
Jefft0, we should not diverge from the standard semantics of domain, i.e. rdfs:domain. This property will be an important basis for inference, like instance of (P31) having the semantics of rdf:type and subclass of (P279) having the semantics of rdfs:subClassOf. More specifically, Wikidata's domain property should take the semantics as used in OWL 2 DL, the reference ontology language of the Semantic Web.
Your concern about conflation among relata is warranted. The folks at WikiProject Molecular biology have fortunately already split Wikidata's items about genes from items about their products; see Wikidata_talk:WikiProject_Molecular_biology#Distinguishing_between_genes_and_proteins. But conflation affects other swaths of knowledge -- e.g. infectious diseases are often conflated with their pathogen, and other effects with their causes.
Having a domain property will standard semantics will help reveal these logical issues. It will also make Wikidata more interoperable with the rest of the Semantic Web. Emw (talk) 03:06, 4 December 2014 (UTC)
  • Pictogram voting comment.svg Comment. Filceolaire, Laddo, TomT0m, Paperoastro, Jefft0, I have changed the proposed property's description from "type(s) of items that may bear this property" to an extremely close paraphrasing of the definition of rdfs:domain: "any resource that has this property is an instance of one or more of those classes". The former definition was vague and could be interpreted as having non-W3C semantics. It's important to align our definitions with the W3C standards to ensure interoperability with the rest of the Semantic Web. Emw (talk) 05:04, 19 December 2014 (UTC)

  • Symbol oppose vote.svg OpposeSymbol oppose vote.svg Oppose Ontotext's experience with large LOD datasets shows that the semantics of rdfs:domain and rdfs:range are often useless and even dangerous, because they propagate wrongly applied properties into wrong types.
    • The "infer" semantics of these properties is surprising to most people (anyone with an OO background), who expect a "constraint" semantics.
    • That's the reason why schema.org has NOT adopted rdfs:domain and rdfs:range but weaker schema:domainIncludes and schema:rangeIncludes. Please read "The decision to allow multiple domains and ranges was purely pragmatic" on that page and reflect upon it! schema.org is a large ontology, supported by all search engines, and has a good class hierarchy and good props.
    • Wikidata has good props (due to strong editorial process) but horrible class hierarchy. Don't exacerbate this problem by inferring types from property assertions! Let's first look at how can we fix the class hierarchy.
    • "is an instance of one or more of those classes" doesn't work with rdfs:domain&range, because rdfs:domain=class1,class2 infers both classes as type of object. Eg on dbpedia mapping wiki, someone said that the domain of firstAscentYear is Peak,Volcano (meaning either peak or volcano). But now every ascended thing becomes BOTH a peak and a volcano :-(
    • The DBpedia ObjectProperty extractor doesn't pay attention to declared domain/range of properties (so on DBpedia these are "wishful thinking" really). So if you apply domain/range reasoning, you'll mis-type all kinds of objects.

  • I would support starting with a "weak" property meaning "only items that are instances of at least one of the classes indicated here can have this property". So really a straightforward replacement for Template:Constraint:Type|relation=instance (not sure for |relation = subclass).
    As for rdfs domain, am not opposed to creating it as a second, separate property, but I am not convinced it is really enforceable in Wikidata.
    I am inclined to think those properties would be mostly useful as maintenance tools (sanity checks, add missing p31..) than for inferrence. "property:father domain:person" might tell us that everything with a father is a person, but I do not quite see the point of knowing that given that anyhow any item with a father statement should also be marked as an instance of person through P31 and P279.--Zolo (talk) 22:22, 29 December 2014 (UTC)

I've tweaked the description again to use an extremely close paraphrasing of the definition of rdfs:range: "the values of this property are instances of one or more of those classes".

Constraints declared in statements on properties will not be enforced in Wikibase. I think that's wise; hard constraints are not a good idea at this phase in Wikidata's development. Domain and range are fundamental properties used throughout the Semantic Web. Bots and other tools can be built as we make statements about domain and range. Let's not wait another 6 months, let's create this property soon. Emw (talk) 19:41, 7 December 2014 (UTC)
We don't need to have these constraints used in the Wikibase system but I don't want to use template in the talk page and statements to define constraints: only one place should be used to describe the constraints and to feed the constraint checking bots. Snipre (talk) 15:05, 9 December 2014 (UTC)
Snipre, I agree. Statements on properties involving metaproperties like range, domain, inverse of, etc. would be the sole place for such constraints. In time, they would replace the system of templates currently used in property talk pages. But we need to create these properties first. Emw (talk) 01:21, 10 December 2014 (UTC)
@Snipre: Could you provide link to the system discussion, definition, roadmap or something else? — Ivan A. Krestinin (talk) 20:25, 12 December 2014 (UTC)
@Ivan A. Krestinin: Better ask for Lydia. The only thing I have is this comment from her.
Emw No. If there is no use, no creation. We should wait until we see the final system in order to create the correct and most appropriate properties. I don't want to have to modify and to delete an bunch of statements which were bad used. Snipre (talk) 07:41, 13 December 2014 (UTC)
Snipre, again, constraints declared in statements on properties will not be enforced in Wikibase, per the Wikidata development plan. The development plan comes from Lydia. The reason statements on properties exist is to replace the hackish Property Talk page templates with content on the Property page itself. Range is a fundamental property used throughout the Semantic Web in precisely the way it is being proposed here. This is "the correct and most appropriate" property for what is being proposed here. Bot implementers and third parties using RDF exports cannot being work with this property until it is created. Waiting "until we see the final system in order" is putting the horse before the cart. If you have some reason to object to using range as defined in W3C standards (which is what is being proposed here) then please outline that. Otherwise, we should move forward and create this property.
Ivan, Innocent bystander, Tobias, Zolo, others, could you please weigh in here, preferably including a concrete 'Support' or 'Oppose' vote with any explanation? I do not want to let this proposal languish for months. Let's decide to create it or not. If not, let's come up with things we need from the Wikidata development team in order to use this most basic of properties. I for one think we should get on with it and create this property for the reasons described above. Emw (talk) 02:38, 19 December 2014 (UTC)
As for me the property is useless without other properties described in #Originally proposed section below. Also current suggestion mixes different relations: {{Constraint:Value type|relation=instance}}, {{Constraint:Value type|relation=subclass}}, {{Constraint:One of}}. I think we need concertize the property meaning. — Ivan A. Krestinin (talk) 05:03, 19 December 2014 (UTC)
Emw If you read my comment you will see that I never speak about constraints enforced in Wikibase. Before any creation we have to have a good idea about what we will have at the end. First from the comment of Lydia I pointed it seems that a group of students is working on the constraints. Do you know that thing ? For me this is not clear so first we have to clarify that thing. Then if we create this property statements is it planned with the current bot to migrate from the current system using the talk page templates to the new statements system ? I am not against this property I just want a clear technical solution with the implication of all persons using these constraints. I want to avoid a mixture of systems, I want to be able to delete the talk page templates when I create the corresponding statements about the constraints. I don't want to see statements about constraints AND talk page templates at the same time because the next time we will have to change a constraint we have to know where we have to change it. Is my position clear now ? Snipre (talk) 10:03, 19 December 2014 (UTC)
I know about the student group, but I do not see any activity of this group, no planes, no declarations, no roadmaps. So I think about current system migration from templates on talk pages to properties. This migration requires a number of new properties. But I want to avoid properties duplication. So created properties must be usable for constraints checks too. Now we already have some duplication: allowed values of {{Property documentation}} is duplicate class parameter of {{Constraint:Value type}} and values of {{Constraint:One of}}. This duplication present because allowed values is not defined enough. Relation between it and property values can be instance, subclass, value list or another. Will new domain property be bad defined too? — Ivan A. Krestinin (talk) 22:19, 19 December 2014 (UTC)

A range implies... a minimum value and a maximum value? A domain? A set of allowed values? An item representing a numerical domain? -- LaddΩ chat ;) 03:45, 12 November 2014 (UTC)

User:Laddo, see rdfs:range and https://www.google.com/search?q=rdfs%3Arange. I recommend Googling "rdf rdfs owl (name of property)" if you're unsure of the meaning of these proposals. These properties of properties should all be based on properties in RDF, RDFS and OWL -- i.e. Semantic Web standards.
We should deprecate "allowed values" as soon as possible. It's unclear whether it refers to rdfs:range or owl:oneOf. Editors routinely use "allowed values" both ways, making the property quite ambiguous. Emw (talk) 12:38, 14 November 2014 (UTC)
I agree that "allowed values" is kind of a melting pot at the moment, and I'd gladly get rid of it, but it's hard to stop using it as long as the properties from this section cannot be implemented. -- LaddΩ chat ;) 00:30, 15 November 2014 (UTC)
Emw, LaddΩ If I am reading the definition you linked to properly it is saying that rdf:range should always link to a Class which in wikidata terms means it should always link to an item which has a subclass of statement. This means that rdf:range is not equivalent to this property. This property is for defining the acceptable values for date or number items which is quite different from rdf:range. Can you confirm that is your interpretation of rdfs:range ? Filceolaire (talk) 22:18, 17 November 2014 (UTC)
Filceolaire, you're right, thanks for the careful reading. I've struck my support. There are other way to encode this information in OWL, but range is not it. Emw (talk) 03:47, 19 December 2014 (UTC)
Name changed from 'Numeric value Domain. Wording of the description changed to make clear this property refers to the Range and not the Domain. The more I look at this the more it seems to me that Domain and Range should link both to Query entities. Queries will have functions like has statement:Instance of:human and more than:0. and has format:NNN??#. Anyone else see that? Filceolaire (talk) 22:44, 17 November 2014 (UTC)
@Filceolaire: I used "numerical domain" because I thought it might specify not only the min and max, but also the nature of acceptable values: real number (Q12916) (floats), integer (Q12503), natural number (Q21199), rational number (Q1244890)... I'm pretty sure a query is not adequate for a numerical domain/range, but since I haven't yet read rdfs:range, let me give a more informed opinion in a couple more days. -- LaddΩ chat ;) 02:18, 20 November 2014 (UTC)
LaddΩ, rdf:range links to a class of items so it will be of no use for properties with date, numeric or text datatype. It is only for Properties with Item datatype. My point was that the kinds of properties we need for defining the range of Date, numeric and text datatypes look more like queries and less like the properties we use with itemsFilceolaire (talk) 11:17, 20 November 2014 (UTC)

comment: Editor Laddo has asked for my comments. I come here knowing nothing about Wikidata. That is my <rant />. I am very much in favor of the liberal use of descriptions that aid understanding so for that reason I am in favor of Description. In re-reading my <rant />, I think that I failed to get across the essence of what I wanted to say. If I am writing a template that uses some wikidata property, I can, I presume, troll wikidata until I find it and then I can include it in my template. Because I did the research, I know what that cryptic bit of text is and what it means (at least for the short term). Some time later another editor reading my template's code might be able to infer what {{#property:P289}} is and does, but without she researches it, she won't know. So, perhaps what it is that I'm looking for is some way to alias {{#property:P289}} to something that immediately conveys to a human reader what that property thing is / does without needing to look it up every time I see it (because I won't remember day to day what it means – I suspect that to be a common affliction, especially as we age).

Here is Editor Laddo's snippet of en:Template:Infobox ship characteristics/sandbox that uses {{#property:P289}}:

{{#if:{{{Ship class|}}}<!-- either -->{{#property:P289}}|<tr style="vertical-align:top;"><td>Class & type:</td><td>
{{#if:{{{Ship class|}}}|{{{Ship class|}}}|[[{{#property:P289}}]]}}</td></tr>
}}

When I first saw this it was a meaningless change because I couldn't attach meaning to {{#property:P289}}. After some study, I could infer that it might provide ship-class information if the template didn't already have it. If there were such a thing as {{#property_alias:ship_class}} then Editor Laddo's code would look like this and anyone reading it would have a much better chance of understanding the code at first reading without needing a dictionary:

{{#if:{{{Ship class|}}}<!-- either -->{{#property_alias:ship_class}}|<tr style="vertical-align:top;"><td>Class & type:</td><td>
{{#if:{{{Ship class|}}}|{{{Ship class|}}}|[[{{#property_alias:ship_class}}]]}}</td></tr>
}}

I am old enough to remember programming in BASIC on the first IBM PCs. In those days, variable names were one or two characters. It was great to move on to C where variable names could mean something. Wikidata properties that are just numbers seem like a throwback to those not-so-great days of BASIC. Am I making any sense?

I would add one other, unrelated comment. At enwiki, the use of tooltips is rather strongly discouraged for reasons of accessibility (see en:Wikipedia:Manual_of_Style/Accessibility#Text).

  • Closed this as not done, because the request has been open for about a month and it lacks a proper motivation and description and the example is unclear. This makes it impossible to create the property. Mbch331 (talk) 11:40, 8 November 2015 (UTC)

      • We shouldn't guess what it's meant for, we shouldn't go to other projects to see why a proposal has been done. The example doesn't match the allowed values, so the example is invalid. When asked for more information by 2 opposes, no information is provided. When I mark the proposal as not done, additional information is provided. The information needed to create a property should be provided upon the moment of proposing the property. And still not all information is provided. A link to a template isn't a property title. If you still want this property, place a proper request that doesn't make others guessing at what you want. Mbch331 (talk) 14:30, 8 November 2015 (UTC)
        • It's not clear if all opposes actually read the proposal, so I'd rather not get involved. IMHO the template needs to be checked in detail to assess the proposal. Obviously, it can help to re-state the project goal each time and, yes, including "en:Template:" in the label isn't needed, but we wouldn't have done that anyways. --- Jura 15:50, 8 November 2015 (UTC)

I've gone further and read the linked template, but it is a WP template and doesn't say anything about Wikidata implementation. If we don't have that information, then there really isn't anything to work with here and thus my opposition until the proposal is fleshed out to actually explain what the property is, what it is meant to do, and how it should be implemented.

    Symbol oppose vote.svg Oppose the name, and that the value includes a unit - I would restrict input to metric and mm. There are too many systems otherwise, Imperial, Portuguese, Spanish, Swedish, Prussian ... support the general idea. Please see the proposal for #Track gauge below. HSRtrack (talk) 18:24, 14 May 2013 (UTC) Changed to Symbol support vote.svg Support after merging the two proposals. HSRtrack (talk) 22:53, 23 May 2013 (UTC)
    Comments: I agree with HSRtrack that is should be numeric (in mm, without unit). en:wiki uses this list: en:Template:RailGauge/entry_check.
    Small gauges <100 mm: Note that small gauges are used too (say under 100 mm), mostly for toys and models. In [:en:Template:RailGauge], they are not separated. Now about precision: if we adhere to the generic safe 3 significant figures of precision, we'll need decimal places when the gauge is under 100 mm.
    Definition in inches: Some rail gauges are defined in imperial measures originally (inches). These may well be converted to mm, provided that re-converting to inches results in the same defined imperial measure. This is called a round-trip conversion check. It can be demonstrated that in this an integer value in mm (say >100mm) corresponds to 132 inch or larger. (That is: calculating back from mm to inch results in 132 inches or larger, so there is no overprecision since there are no gauges defined by 164.)
    For gauges <100mm (including to-scale models) one should/could use decimal inch values. An issue here could be: when the scale is defined like 1:132, typically imperial, the round trip check should work. en:User:DePiep= -DePiep (talk) 10:07, 16 May 2013 (UTC)
    I added a section about units at en:track gauge. Support two decimal digits as found in en:List of rail transport modelling scale standards HSRtrack (talk) 16:50, 22 May 2013 (UTC)
    Symbol support vote.svg Support Don't worry about the number of decimals - datatype number can support any number of decimal places and nothing here will influence that. Filceolaire (talk) 12:58, 26 May 2013 (UTC)
    Maybe restriction to two decimal places is wanted, since it disallows inputs like 1000.0000000001, 1000.000000001 (one zero less), 1000.0000000002 HSRtrack (talk) 13:16, 26 May 2013 (UTC)
    IMHO it should be of "number with unit" datatype. --Ricordisamoa 18:34, 28 May 2013 (UTC)
    Why do we need unit? It will be simplier if use one unit. And in infobox we can make units conversion.--Ahonc (talk) 20:54, 28 May 2013 (UTC)
    If the unit is always "mm" as proposed, then it is redundant. If the unit can be different from mm, then it will render lot of data useless to many people. What is 1 Prussian foot? HSRtrack (talk) 21:40, 28 May 2013 (UTC)

    This property would be similar to endemic to (P183) but for languages, dialects, folk dances, cooking styles and other regional cultural expressions instead of species Filceolaire (talk) 00:25, 7 November 2014 (UTC)

    Symbol support vote.svg Support I was looking for a way to link instruments to where they're from but couldn't find any suitable property. This seems to be what I was looking for.
    One thing I would say, though, is that culture is the result of a group of people behaving in a common way and many (if not most) cultural things are really linked to an ethnic group (Q41710) or social group (Q874405) (including religious groups) and then to specific areas via the regions those groups of people live in, rather than directly to an area. Not all groups of people have a clearly defined area either.
    Some examples: haka (Q3595586) is a dance of the Māori people (Q6122670) of New Zealand (Q664), Muong (Q3236789) is spoken by the Muong people (Q72805) of Vietnam (Q881), t'rưng (Q7667735) is an instrument used by the Jarai people (Q2467559) and Bahnar people (Q1347290) of Vietnam (Q881), Hmong language (Q33813) is spoken by the Hmong people (Q219205) of southern People's Republic of China (Q148), Vietnam (Q881), Laos (Q819) and Thailand (Q869), Ainu cuisine (Q4697541) is the style of cooking of the Ainu people (Q101828) of northern Japan (Q17).

    • Symbol oppose vote.svg Oppose. The images you link to show the upper note and the lower note that the instrument can play. Wouldn't it be much better to have statements giving the upper and lower notes? That way we could not only automatically generate these images we could also use this info in other ways? You could use this for the range a singers voice could achieve too. I would suggest using datatype "item" for these "upper note" and "lower note" properties - we can have items for each note all the way up to the highest and lowest notes large organs can achieve.

      • Why not both? I would support adding properties and items for the upper and lower notes too, but I don't think that would replace the images. Generating the images automatically is a nice idea in theory, but it's not that simple to do. Both examples I linked have more than simply two notes, plus you have to deal with things like choosing the best clef to use. Even if you figure out all the properties needed to provide enough information and create all the necessary items, you then need something which is capable of bringing it all together and something to generate the image itself. It's a rather complicated process to generate an image, especially when the images already exist. - Nikki (talk) 15:37, 29 April 2015 (UTC)
    • Per Filceolaire, far better to have a property for the item representing the top note, and another for the bottom note. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:30, 30 April 2015 (UTC)
      The existing images are stored on Commons and references to the images are duplicated across Wikipedias (e.g. commons:File:Range_flute.png is used by 25 different Wikipedias). It would make sense if the infoboxes could access references to the images from a central data repository instead of having to duplicate them. Isn't that exactly one of the reasons Wikidata exists?
      Not having this property will not stop the images from being added, they will just end up being added using image (P18) instead (as has already happened for western concert flute (Q209554)), which seems rather suboptimal, since as I mentioned, image (P18) would normally be used for pictures of the instrument itself, not for its playing range. They are images of two completely different things, so it makes sense to keep them separated.

    "pts/supertuxkart" seems to be a test suite rather than a product result. That is why it is in "http://openbenchmarking.org/test/" rather than "http://openbenchmarking.org/results/".

    It also seems to me that a particular grammatical category is not really a "class", but I'm open to discussion. Popcorndude (talk) 00:57, 21 August 2015 (UTC)
    @Popcorndude: There is linguistic discussions on the enwiki article on type–token distinction (Q175928). So yes, I say it's modellable by classes. There is a class of sentences in which a special grammatical category appears. If a sentence is made of words of other linguistic entities, then each linguistic entity can be bound to fulfil a grammatical role ... subjonctive is bound to a class of particular forms of verbs ...
    If I say that the "subjonctive" concept is very closely related to all the sentenses (or sentences parts) that are written in the subjonctive mode, would make sense ? We could say "this is subjonctive" irl. Then "subjonctive" would be a subclass of sentences, or the precise relevant linguistic items. "Grammatical mode" would be the metaclass (see Help:Classification) of all the relevant classes of sentences relevant to model grammar. I think this would do the trick.author  TomT0m / talk page 07:19, 21 August 2015 (UTC)

    User:SynConlanger, the idea was to link grammemes (past tense, subjunctive, perfect, dual, etc.) with the corresponding grammatical category (tense, mood, aspect, number, etc.). However, now that I think about it, User:TomT0m is right (so far as I understand him), and this could just as easily be modeled by having all the grammatical categories be subclasses of grammatical category, and then just have all the grammemes be subclasses of them and instances of grammeme. Is that what you meant TomT0m, or have I totally misunderstood your suggestion? Popcorndude (talk) 15:33, 21 August 2015 (UTC)
    @Popcorndude: I think we're on the same page :) I did not know the grammeme word. author  TomT0m / talk page 15:40, 21 August 2015 (UTC)
    Grammeme is a quite obsolete term for an emic grammatical entity. It was in vogue during the "tagmemic linguistic" era. But I'm a phonetician/phonologist not a morphosyntactician so I may be wrong! But I got the point! I agree in having "grammatical category" < "tense" < "past" and the like (where < means "contains the subclass" or whatever it may be metadata-ly speaking). --SynConlanger (talk) 17:17, 21 August 2015 (UTC)
    In that case I will retract this proposal. I would not be surprised to find that some other term is now prefered to "grammeme", but it was an item that already existed, so it seems like I might as well use it anyway. Popcorndude (talk) 17:45, 21 August 2015 (UTC)

Anyway, to get rid of the wording, we should use a more precise definition, such as "horizontal, vertical and depth" or x,y,z coordinates of the bounding box of an object, where x is the front horizontal measure, y is the front vertical measure and z is the depth of the box, and the object is seen with the front to back side aligned with the z axis.

            • It's worse than that. In English a football pitch has length and width. Do other languages have these four names (length, height, depth, width) with the same meanings. Plus (in English) a building has height above ground level but a hole has depth below ground level and so both refer to the vertical dimension in those cases Holes have a side-to-side width dimension and a front-to-back dimension which we can't call depth because that is the top-to-bottom dimension.

    Je voudrais créer les propriétés sémantiques pour décrire un jeu de données. L'unité statistique permet de décrire l'élément représenté dans la base de données.

    I would like to create semantic properties which describe a dataset. A statistical unit is the unit of the dataset. For instance, this can be a country for the Penn World Tables dataset, an item for Wikidata, an individual in a poll, an household in an official statistical survey such as Labor Force survey or even a street in datasets like FANTOIR.

    In eswiki we want to link items of countries and municipalities to the list of municipalities for that country. I asked about it in the Project chat how to do it and they suggested the use of a generic property like "has list" that has to be created (because I found properties for specific lists but not a generic one to use for this use case).

      @Pigsonthewing: Up to a point, but that shouldn't necessarily count against it. To start with, even when an inverse property like is a list of (P360) exists, there's no way to search and access that inverse relationship in Lua, eg from the infobox for Spain. Secondly, even given that P360 exists, how (even in SPARQL) does one find lists which are relevant to the whole of Spain ? The P360 statement might have the qualifier country (P17) = Spain (Q29) -- or it might not. It might be implicit in the thing that the list was of eg municipality of Spain (Q2074737) -- but it's quite hard to frame a search for "things which are specific to Spain" (that we might have a list of). Then one would need to check that the list was not subject to a further narrowing limitation -- eg "list of municipality of Spain (Q2074737) in Andulusia". And even with all that, one would still not get to the real motivation for this property, to identify lists related to Spain that are sufficiently significant to consider linking to from the infobox for Spain.
      I am not sure I see how all that could be achieved just with P360. Jheald (talk) 15:49, 24 November 2015 (UTC)
      @Pigsonthewing: If you have better ideas I accept suggestions. I asked in the Wikidata:Project chat and proposed this suggestion to stop people of eswiki from adding the list as instance of (P31) and removing the other elements for the municipalities. This is the best solution I get and it would be a lot of work for me to make our template to work with Lua instead of with Wikicode, so if you have a better solution I am completely willing to know it. -- Agabi10 (talk) 23:21, 24 November 2015 (UTC)

    Such qualifier is useful only for specific kind of map projection (Q186386) (usually small) in which latitude and longitude can be converted to x and y value in the picture of map using linear function (Q188597). However if you look at Antarctica.svg, the translation to x and y is rather complex. The general solution to the problem is creating function, which test whether the given coordinate is visible on the map, and converts it to pair of (x, y) in the picture. Paweł Ziemian (talk) 11:54, 13 June 2015 (UTC)
    @Filceolaire: A statement with coordinates of northernmost point (P1332) d:o 1333, 1334 and 1335 have all both latitude and longitude. Adding all four, therefor gives 4 longitudes + 4 latitudes = 8 numbers. That would give us an unsolvable system of linear equations (Q11203). We need exactly four numbers here to copy the functions of present templates like Template:Location map Andorra (Q12259). That is easiest accomplished by adding coordinates of the most NW and SE points of the map.
    @Paweł Ziemian: That also includes nations like Russia and Greenland. They are the exceptions, they cannot be solved in a simple way like most other nations and regions in the world. -- Innocent bystander (talk) 18:05, 6 July 2015 (UTC)
    Yes, I know. It was an example, where the problem is easiest to observe (I think). Paweł Ziemian (talk) 18:43, 6 July 2015 (UTC)
    Innocent bystander What if we take the 'northernmost' and 'southernmost' points and discard their longitude values and then take the 'easternmost' and 'westernmost' and discard the latitude. Now we have two latitude values and two longitude values and the problem of finding NW and SE coordinates from these is solvable. Greenland shouldn't be a problem nor should Russia since we specify which point is easternmost and which is westernmost. Antartica only has a 'northernmost' point, defining a circular map. Similarly for the Artic sea. Easy peasy.
    "Ah" you say "but that means the map of russia and of greenland is not square!" and I say that depends on which projection you are using. These maps are square if you use the Peters equal area projection for instance. This will, however, distort the shape of Russia and Greenland. You would be better to use a polar projection for the maps. The centre of this polar projection should be at a latitude half way between the 'northernmost' and 'southernmost' points and a longitude half way between the east and west extreme points. Not hard to calculate. The north south east and west limits of the maps should be at or beyond the NSEW extreme points. Sounds perfectly possible to me. Google earth does this all the time - draws a polar projection with a centre point wherever the centre of your screen is. I'm still Opposed to creating new properties. Filceolaire (talk) 00:27, 8 July 2015 (UTC)
    A map of Russia or Greenland with the same longitude in the left upper and left lower corner are possible to create, but they are aestheticly awkward. Maps with other kind of projections exists in these cases, so it is solvable. The problem is that somebody have to create these maps and templates. We are not flooded with such skilled users on Commons and the Wikipedias. -- Innocent bystander (talk) 05:05, 8 July 2015 (UTC)
    This guy got an individual engagement grant to do exactly these maps. You should talk to him. Filceolaire (talk) 22:33, 16 July 2015 (UTC)
    There are several use cases with map overlays, where the placement of the overlay object would be needed. I had thought of using the northernmost coordinate and it's companions, but they are coordinate points, consisting of both longitude and latitude. This means there has to be either a more suitable property (a corner point, such as presented here) or a more suitable datatype (lat or long only, and a corresponding property). I think the previous would be more lightweight. So, I Symbol support vote.svg Support --Susannaanas (talk) 08:37, 14 September 2015 (UTC)

    I would delete female population (P1539) and male population (P1540) as well. Just use population (P1082) with qualifier applies to part (P518) then it can be used for all the cross tabs in the census - sex, age, religion, race, etc. Filceolaire (talk) 16:50, 30 April 2015 (UTC)
    @Filceolaire: Is it the concept you don't like or the formulation? How about a gender neutrally formulated property for the gender ratio? There is en:List of countries by sex ratio, but I'd rather see a percentage of total. Male ratio could work as well, but focus is frequently on the female part. --- Jura 17:04, 30 April 2015 (UTC)
    @Filceolaire: care to explain? --- Jura 02:19, 3 May 2015 (UTC)
    Jura, Antrocent I have been thinking about how we can express this in a gender neutral way. I think I would prefer the property was called "Proportion of population". Examples:
    "Proportion of population:0.8(applies to part:male)", "Proportion of population:0.2(applies to part:female)", "Proportion of population:0.1(applies to part:Roman Catholic)", "Proportion of population:0.08(applies to part:HIV positive)". When the number of people who identify as neither male nor female goes above 0.005 we should include them in the info boxes. With this property we can do that. We won't need to redefine the property. OK? Filceolaire (talk) 23:36, 5 May 2015 (UTC)
    This is tempting indeed and could store the information:
    • Using a generic field mixing it with other information is always possible, but generally not preferred (the answer to the question asked by Filceolaire is here).
    • In this case, it would complicate things twice:
      1. once we have to check if the property actually contains information about the gender ratio,
      2. then if it's the male or the female part.
    I suppose it's still not gender neutral, as one would have to pick one or the other when adding the statement. --- Jura 10:54, 8 May 2015 (UTC)

    For EU databases, bots or other automated ways of extracting data should also be avoided
    because of the Directive’s prohibition on “repeated and systematic extraction” of even insubstantial amounts of data.
    

    This suggests another couple of statements we need to be able to make about our authority control properties and other properties that refer to databases.

    Discussion

    This is a spatial extent for an object in some direction, going perpendicular on a plane, and unless otherwise specified it is the maximum length in any direction.

    • A qualifier instance of (height (Q208826) is this right?) would take whats given as subject item above and will specify what the extent measure. (For example the height of a mountain.)
    • A qualifier geoid (perhaps better called datum) which gives the interpretation of the items referenced, that is a height is according to the instance of. Default is WGS84 (World Geodetic System (Q215848)).
    • A qualifier reference item which would be interpreted according to the instance of and geoid if that is given. The measured length is by extension to the surface of this item. Could be an extended plane.
    • A qualifier extent coordinate system to specify the local coordinate system. Default is spherical coordinate system (Q203218).
    • A qualifier azimuth or orientation according to the instance of and geoide. Defaults to "unknown".
    • A qualifier inclination or polar angle according to the instance of and geoide. Defaults to "unknown".

    Tried to reformulate the spatial extents to be a single generic one. It seems that there is a problem whether the system is a local one when the reference system point back to itself or the geoid is undefined, or it is a global one references something else. One way around could be to drop geoid and only use reference item and infer geoid from this item. The item lives within some other system or is self referencing. No reference item would be interpreted as a self reference.

    Note that if the azimuth and/or inclination is set wrong the measurement axis my never touch the surface of the reference item. Jeblad (talk) 01:38, 30 October 2014 (UTC)

    Wait until we have the 'number with dimension' datatype, though I am really not clear how this is used and whether it would be better using a collection of specific properties such as 'Base' for mountains. Filceolaire (talk) 20:59, 31 October 2014 (UTC)
    Filceolaire can you point me to wherever a discussion about a 'number with dimension' datatype is going on? Getting a quantity datatype right is difficult, but rather easy compared to a dimension datatype. To make an example, a length dimension can exist and within that dimension there can be two length measures that can not be compared. Most of the time this situation arise because of lost knowledge about how base units relates, or becase there is (or was) conflicting definitions. My favorite example is the length measure "coffestops", see also m:Wikidata/Notes/Values. Another nice one is that "there are 4 stone throws (w:no:Steinkast) on one arrow shot (w:no:Pilskudd)", that is old Norse length measures. There is also "vika sjóvar" which is the distance you row a boat in two hours, which is calculated to be 11 112 meter on Wikipedia. :D In effect you have subdimensions within a dimension, but note that subdimensions in this case does not imply subclasses you can cast to a common baseclass (length is an abstract property and you can't cast a coffestop to a base class). Anyhow, I think it is better to create usable solutions and reprocess existing properties later when someone create the perfect solution. Jeblad (talk) 15:32, 5 November 2014 (UTC)
    See Wikidata:Requests_for_comment/Dimensions_and_units_for_the_quantity_datatype. Filceolaire (talk) 19:08, 5 November 2014 (UTC)
    I saw that page, didn't realize it was a proposed as an implementation. As it stands it is probably not a solution, in fact I think it will make it really hard to solve some real-world problems.
    Perhaps I should try to make a better explanation. That page describe the preferred units to use, it does not describe the role the measurement have. A property (predicate) describes the role a specific value (object) has in relation to an item (subject). An extent is such a property, and that will use a length measurement, possibly with units according to the given page. It is possible to use a length as a property, but then you must add qualifiers to say that this is in fact an extent. I think it is better to say what you measure with the property itself, and then add refinements to that, otherwise you need qualifiers about qualifiers (statements about reified statements about reified statements). An extent can have an orientation, but a length does not have one. It might not even be a measurement in a straight line. Jeblad (talk) 19:43, 5 November 2014 (UTC)
    In this case instance-of seems to be right as this would be a statement about a height, that is a height measurement. Usually it is wrong to use instance-of as a qualifier, that is rdf:type about a statement. Jeblad (talk) 02:32, 23 November 2014 (UTC)
    Pictogram voting comment.svg Comment. Jeblad, Filceolaire, how about using first-class properties like height (or spatial height) when applicable, and this property for more complex spatial extents? This approach works well for our kinship properties, where we have first-class properties like mother, father, brother, sister and child for basic relations, and relative with a type of kinship qualifier for more distant relations.

    I wonder if there should be no default for geoid, and the interpretation should be length along major axis. The next minor axis in following order will then give the reference system according to the right hand rule. Jeblad (talk) 14:11, 28 February 2015 (UTC)

    Properties Litholex ID (P731), BGS Lexicon ID (P732) and DINOloket (P733) are examples of similar properties which exist for stratigraphic unit identification systems of other countries. This property proposal allows for Australian stratigraphic units to be linked to the authoritative catalogue (the Australian Stratigraphic Units Database) for such information on Australia.

    The Australian Stratigraphic Units Database (ASUD) originated as the National Register of Stratigraphic Names in 1949. The register was originally set up to help geoscientists adhere to the (then) newly created Australian Code of Stratigraphic Nomenclature (Lenz, et al, 1996). All information was held in a card file system until 1979 when the database was first developed electronically. The database now records information on all Australian stratigraphic units and their usage in literature, making it a centralised reference point for all Australian stratigraphic unit information. The database is also the repository for definition descriptions for these units. The database is maintained by Geoscience Australia in collaboration with the Geological Society of Australia's Australian Stratigraphy Commission. Dhx1 (talk) 10:22, 22 November 2015 (UTC)

    • BA candidate.svg Weak oppose To be clear, this is a (very) miniature version of what one may find on Wikipedia. I see a few issues with this specific website. 1. its title makes you think of everything about Shakespeare, but it's mainly where Russia intersects with Shakespeare, excluding most important information. 2. It still seems to be in its infancy and doesn't cover many topics, but does cover topics such as "Shakespeare in Russia." 3. The ID for the article in Russian is not the same ID for the article in English. For the example above, the English ID is 4360 (vs. 4284), so the URL is http://world-shake.ru/en/Encyclopaedia/4360.html. Nonetheless, if we only care about the Russian language section, this is moot. 4. I saw at least two likely copyright violations on the website, specifically with images. I only browsed a few pages so they may be the only ones. While it's not against policy as far as I know, it is still something we should keep in mind when linking to external sites. On the other hand, the site seems to be on the right track and has a plethora of references in each article, some inline, some not, so in some ways. Hazmat2 (talk) 22:47, 21 May 2015 (UTC)

    Proposal format

    @Zolo: Please complete the template for each of these nominations. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:44, 5 November 2015 (UTC)
    @Pigsonthewing: once again, what's the point of adding {{Property documentation}} here ? It would not add any useful information, and would arguably blur the connection between the three proposed properties (perhaps we should just have one property or whatever). --Zolo (talk) 15:42, 6 November 2015 (UTC)
    @Zolo: Once again, this was explained to you on 19 October, by User:Nikki. Your continued obstinacy in this matter is unbecoming of an admin. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:55, 6 November 2015 (UTC)
    @Pigsonthewing: as you can see I had replied to Nikki at the time, and so had Jura. The template would not add anything relevant for this proposal, just translate a few words, so few that it couldn't possibly include more people in the discussion. You can't assume I will comply with your request if you are unable to provide a rationale. --Zolo (talk) 07:50, 7 November 2015 (UTC)
    Interesting discussion! @Zolo: - I think you should go ahead and create those proper requests because that needs to be made in oder to complete the property (and the property will link back to this page). Not doing so just forces Andy to do it for you, which I just see as being impolite and putting the burden on the admin rather than the proposer. --Jane023 (talk) 10:05, 8 November 2015 (UTC)
    Andy has visibly no intention to add the template, and I am certainly not suggesting that he should. I would just like to know why it would be helpful to add it in this case. Afaik, the only recent discussion on the topic was in the mix'n'match section of Wikidata:Property proposal/Archive/39, and that was inconclusive at best.
    Now that there are statements on properties, mechanically copying the template from the proposal page should be avoided, as it adds a lot of redundant data that need to be cleaned up. If you look at the latest properties I created like Property talk:P2266, it does not reuse anything from the template from the discussion, nor should it. Had there be no template like here, things would have been done exactly the same way. --Zolo (talk) 10:53, 8 November 2015 (UTC)
    What seems even more problematic is that if you use the template, Pigsonthewing edits the content of the proposal template without noting the changes in the comments making it difficulte to determine what people agreed to (Diff). --- Jura 11:24, 8 November 2015 (UTC)
    Jura1 is upset because I fixed some formatting errors in a proposal he recently made. This is normal, and I reminded him on my talk page that he doesn't "own" the proposal. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:53, 8 November 2015 (UTC)
    I wasn't even involved in the proposal mentioned in the diff. --- Jura 13:55, 8 November 2015 (UTC)
    No-one said you were. The diff shows me in the process of cleaning up the template having created the property; as required by the appropriate process (Point 5 at Wikidata:Property creators#Steps when creating properties), and as every template creator should do. Nonetheless, my point about our recent interaction remains valid. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:02, 8 November 2015 (UTC)
    I think you misunderstand the outlined process. Probably because you didn't attempt to follow it. Obviously, I disagree with you doing such edits. --- Jura 14:13, 8 November 2015 (UTC)
    Jane's point is valid, but it is not necessarily me who would have to do the work; whoever creates the property would have had to create the templates, due to Zolo's disruptive refusal to do so. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:58, 8 November 2015 (UTC)
    Let's be creative. Why not divide the process into two steps : formal acceptance after the initial discussion, then creation by the proposer of the required template as a required step before the creation ? A proposal is sometime not mature enough to create the template before discussion, and the template creation is a waste of time if the proposal is rejected. author  TomT0m / talk page 14:07, 8 November 2015 (UTC)
    Because that would deprive us of the benefits of using the template from the outset; and because there is no guarantee that a proponent would return to carry out such a task; or if they did, that they would do so in a timely manner. When used properly, the current process works well (further: no cogent argument has been made that it does not; much else evidence been provided). But again, you are welcome to make such a proposal in the appropriate place, for the community to consider. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:56, 8 November 2015 (UTC)
    @Pigsonthewing: Seriously, you really think that there is evidences that all this process works fine ? Well, just compare the number of infoboxes not migrated yet ... This is so sloooooow ... I can show proposals of mine a year old ... I could read mockeries of wikipedians mock the bureaucraty required to create a single property. author  TomT0m / talk page 20:02, 8 November 2015 (UTC)
    Please explain how not using the template would improve the issues you describe - or indeed how u`sing it causes them. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 01:02, 9 November 2015 (UTC)

    This is a waste of time and energy. I just added the templates. Please do come up with a better way of handling this in the future, but not here. Probably better to move this to Wikidata talk:Property proposal. Maybe create a template like {{Proposed property}} in which you fill out all the information. Once you created the property the template will suggest the missing claims to be added and the contents of the {{Property documentation}} to be added to the talk page. Multichill (talk) 11:54, 8 November 2015 (UTC)

    Thanks for doing it, I have copied that to Wikidata talk:Property proposal--Zolo (talk) 13:41, 8 November 2015 (UTC)
    The better way of handling this is for Zolo to use the standard template in his proposals; as he has been requested to do several times, and not just by me. He is disrupting this page to make a point. If he thinks the template is subomptimal, he is welcome to suggest changes to it (or indeed, its deletion), in order that the community can reach consensus as to whether those changes should be made; or whether the previous consensus, which resulted in this template, holds. Both he and you are admins, and so should be aware that this is how Wikidata works. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:53, 8 November 2015 (UTC)
    Better pursue this off-topic discussion at Wikidata talk:Property proposal. Just some quick clarifications as I find your reaction really puzzling. I have no wish to change the property documentation template. The way Wikidata works is that we need not follow rules when none was ever decided, and none was for the property proposal format. Prior to this discussion, only one other user said we I should have added the template. I had explained why I had not, and a third user supported me, and nothing beyond that. Were it not for your puzzling reaction, there would not have been much disruption. Ok that's all for me here. --Zolo (talk) 23:29, 8 November 2015 (UTC)
    Consensus clearly exists for the process (including use of the template) outlined at the top of this and all its sister pages. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 01:09, 9 November 2015 (UTC)

    • @Pigsonthewing: : I think we need to talk about how to handle these. We already have RKDartist and RKDimages and others from the RKD like Depeicts Iconclass notation, etc. I think there should be some way to connect these so that users are 1) not confused when they select a property and 2) users can easily see the connections. Most large image databases for art will include a separate index for artists, and each is a gateway to the other. We need a better way to handle these. I discussed this a bit yesterday with @Spinster: because we are thinking about addling lots of properties for museum collections that also have similar constructs, including exhibitions or publications. Perhaps we could figure some property that would combine all of them and if used on an item already sorts to the proper sub-property based on the type of item. --Jane023 (talk) 10:05, 8 November 2015 (UTC)
    • Note: I'v taken the libery to reorganize the discussion for readability. --Zolo (talk) 10:53, 8 November 2015 (UTC)
    • @Jane023: indeed if we go on the current way, like with MoMA artwork id (P2014)-MoMA artist id (P2174) many more properties will be created. I am not sure it is really a problem though. Now that we can add statements on properties, things are relatively easy to monitor. --Zolo (talk) 10:53, 8 November 2015 (UTC)
    We noticed there was a problem with the RKDI database on Mix-n-Match - most of the automatches are incorrect - presumably these have been matched incorrectly (or something went wrong when the database was loaded by Magnus). The issue occurs at the moment the user selects the property. You need to look not just for RKD but also the suffix (@Jheald: discussed user notes for this recently on the Wikidata mailing list). --Jane023 (talk) 11:01, 8 November 2015 (UTC)
    • I think it's probably essential to have different properties, because they have different formatters. It would be horrible to have to work out the type of a thing before you could format its URL. It also would very confusing, if the numerical ranges overlap, to have the same value on a single property apparently applying to a number of different things (and make it harder to implement "unique value" constraint violations).
    At the moment we have Art UK artist ID (P1367), Art UK collection ID (P1751), Art UK venue ID (P1602) and Art UK artwork ID (P1679). Those don't appear to have caused any difficulty with data entry; and most uses of a wrong property on a particular kind of item will trigger a constraint violation. There may be a problem if the number of properties associated with a particular institution becomes larger than the size of the drop-down box, but we've not reached that extent here. Jheald (talk) 11:11, 8 November 2015 (UTC)

    • Symbol support vote.svg Support to create separate props. EAGLE id (P1900) uses a single namespace for different kinds of IDs, so their IDs are of the form "objtyp/lod/x" vs "material/lod/y", etc. I don't like the result (incl. the parasitic word "LOD").
    Propose to rename to "FR Agorha ... ID" (including the country code)
    Agree with @Jane023: that this proliferation of props calls for some reorganization in the future. The formatter can take 2 params: authority and kind, and for each authority we need a table which kinds it supports. But this will make adding instances so much more difficult.

    Motivation

    The Australian Aboriginal languages comprise up to twenty-seven language families and isolates native to the Australian Aborigines of Australia. In the late 18th century, there were between 350 and 750 distinct Aboriginal social groupings, and a similar number of languages or dialects. At the start of the 21st century, fewer than 150 Indigenous languages remain in daily use, and all except roughly 20 are highly endangered. The Australian Institute of Aboriginal and Torres Strait Islander Studies (AIATSIS) is an independent Australian Government statutory authority. It is a collecting, publishing and research institute and is considered to be Australia's premier resource for information about the cultures and societies of Aboriginal and Torres Strait Islander peoples. AUSTLANG is therefore perhaps the best catalogue of Aboriginal languages. Dhx1 (talk) 03:06, 22 November 2015 (UTC)

    Classification of Instructional Programs code

    Domainacademic discipline (Q11862829)
    Robot and gadget jobsimport from freely available database, United States Department of Education (Q861556)
    Motivation

    "The Classification of Instructional Programs (CIP) provides a taxonomic scheme that supports the accurate tracking and reporting of fields of study and program completions activity. CIP was originally developed by the U.S. Department of Education's National Center for Education Statistics (NCES) in 1980, with revisions occurring in 1985, 1990, and 2000." The current CIP is from the year 2010. This is the official taxonomy of educational fields of study for the US government, and all colleges and universities have to report graduates based on these values. CIP codes are also hierarchical: 01 is agriculture (Q11451), 01.09 is animal science (Q168091), and 01.0906 is animal nutrition (Q4764962). This directly maps to Wikidata's instance of (P31) and subclass of (P279) schema. With this data, and creating missing academic discipline (Q11862829) entities, we can better support academic major (P812) as well. Runner1928 (talk) 19:02, 11 November 2015 (UTC)

    This statement is partly incorrect.

    If you want to play with the words but you can't discuss the fact that starting June 2015 the GHS is the unique labelling system valid in EU (see ECHA, first lines: "From 1 June 2015, the Classification, Labelling and Packaging (CLP) Regulation will be the only legislation to apply to the classification and labelling of both substances and mixtures.". What you mentioned is a transient agreement for chemicals produced before the date. Temporary exception due to logistic reality doesn't modify the facts that you can't produces any chemical with the old label even if you can ensure the use of this product before 2017 and that all modifications of labelling between July 2015 and now are not more translated in the old system).

    Pictogram voting comment.svg Comment @Almondega: I think a different label would be good, because we don't always link to the species of the animal (also genus etc.). Also there would be the danger of users misusing it as a property and causing problems with the taxonomy properties. Would "animal model" or "model animal" be the better name? Maybe even "observed in animal model"? --Tobias1984 (talk) 17:39, 12 October 2015 (UTC)
    or simply taxon ? Assuming species or genus are kind of taxons. Animal would suggest it's to link to an instance of animal. author  TomT0m / talk page 17:43, 12 October 2015 (UTC)
    @TomT0m: I think longer labels are much easier to understand in a semantic database, because the claims then complete a sentence. "Taxon" "Mouse" means almost nothing in my opinion. And using labels that are close to taxonomy, will result in more conflicts. For example the item Citrus ×limon (Q500) can be viewed from a food or taxonomy perspective. But we can only have one label, so the conflict is between "Citrus ×limon" and "lemon". Similar for chemical compounds that are also used in pharmaceutics. People would use a property "taxon" for a lot of different things. Especially with the qualifiers I tend to think we should provide unambigeous clarity. --Tobias1984 (talk) 18:00, 12 October 2015 (UTC)
    @Tobias1984: "applies to taxon" then. I can understand the need of clear guideline, I'm a little bit more skeptical on having a lot of very closely called properties because it leads to more confusion of one each other. We have a lot of questions "which property should I use, this one or that one ?",

    so I think it actually would not hurt that taxonomy and this field would share a property if the only difference in their use is the field they apply to. Imagine in molecular biology that a protein or some hormon has a specific effect on some kind on animal, or if in taxonomy one has to specify on which taxon a claim is valid, what's the harm to use this qualifier ? How useful would it be to create qualifier "applies to taxon but only if the claim is in the taxonomy" and "applies to taxon if we're talking about a drug" ? author  TomT0m / talk page 18:15, 12 October 2015 (UTC)

    I concur with Tobias1984 that 'species' is far to broadly used a term in other senses to bind it to a property with this specificity. I also think that TomT0m is right to shoot for properties that are fairly general and multi-purpose at this stage in the game. I think a qualifier "applies to taxon" would work for this particular application and would be generally useful in other biological settings. --I9606 (talk) 18:45, 12 October 2015 (UTC)

    Pictogram voting comment.svg Comment One more : you might want to replace the main snak of all this, and make the taxon the main value of the claim. There is potentially, I guess, various type of doses that might apply to the same taxon, lethal dose, mean journal dose, I don't know. Maybe it would make sense to regroup all this kind of doses in the same statement. This would give something like

    < Chemical > can be given to taxon search < cat >

    @Snipre: So, how do you consider the best way to enter this information? --Almondega (talk) 12:41, 3 November 2015 (UTC)
    Like a qualifier for lethal dose or lethal concentration properties. For example, for lethal concentration properties we need the specie/taxon and the duration of the exposition so the proposed structure doesn't allow to have qualifier for qualifier.
    50 lethal dose (property): 50 mg/kg (value)
    specie/taxon (qualifier): rabbit (value)~
    route of administration (P636) (qualifier): oral (value)
    50 lethal concentration (property): 50 mg/l (value)
    specie/taxon (qualifier): rabbit (value)
    duration (qualifier): 20 min (value)
    route of administration (P636) (qualifier): inhalation (value)
    Snipre (talk) 13:20, 3 November 2015 (UTC)
    What solves this is to make one statement per source (that might give several numbers anyway). So this can be done as well with the previous model. With better "visual search" property because the dose does not mean anything without the species. author  TomT0m / talk page 13:24, 3 November 2015 (UTC)

    Köppen–Geiger climate classification system

       Not done
    DescriptionKöppen climate classification is one of the most widely used climate classification systems. It was first published by Russian German climatologist Wladimir Köppen in 1884, with several later modifications by Köppen himself, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger collaborated with Köppen on changes to the classification system, which is thus sometimes referred to as the Köppen–Geiger climate classification system.

      • Various things have been discussed here and there, it's just that it hasn't gotten to the creation of new property. We could simply use the property "numeric value" for any conversion. The idea of this new property is to do SI conversion calculations when possible. We might need another property if there is a rounding issue involved converting between two non-SI units or if there are some units that can't be converted (reliably) into SI units. --- Jura 14:09, 7 October 2015 (UTC)

    • Symbol support vote.svg Support. We need a generic "is equivalent to" (or "size") property but we also need a very specific property converting every measurement unit to SI units. This will be needed to create tools to compare measurements in various units with each other. The tools will need to go straight to this one single value property to get the info they need. If there are three different inches then they need three different items each with one claim using this property or, at worst various historic values and one current, preferred value.

    Robot and gadget jobsprobably, on a per-journal basis
    Motivation

    As discussed here, the paper-age property page(s) (P304) does not necessarily make sense for articles in online journals. Many articles thus have a journal-specific article ID instead of (or sometimes in addition to) traditional page numbers. They predated DOIs and often form the basis for their article-specific parts but cannot be uniformly deduced from DOI (P356), nor do all journals that use them also have DOIs. I think the best way to handle this kind of information here on Wikidata is a dedicated property. Daniel Mietchen (talk) 04:29, 2 August 2015 (UTC)

    Discussion
    • @Pigsonthewing: A URL datatype could make sense if all of these IDs were formatted uniformly, but they vary a lot between journals and also over time within a given journal, while the format of the ID strings themselves varies less across journals and is rather stable over time. --Daniel Mietchen (talk) 22:04, 2 August 2015 (UTC)

    • @Snipre: Not sure I understand what you mean. The concept of DOI is rather well-defined, and it comes with technical infrastructure to resolve individual identifiers belonging to the system, which we use in DOI (P356). Mixing this up with identifiers external to the system does not make sense to me. --Daniel Mietchen (talk) 03:41, 8 August 2015 (UTC)

A hint it's to be used that way : the article may be published in several journal, in that case the id only make sense associated to the journal it is publicated into.

    • I'm afraid I lean against this. Instead we should just have the "replies to" property since the 'being a reply to' thing is always a property of the newer second article. The first article is not written to be responded to. Joe Filceolaire (talk) 09:59, 8 November 2015 (UTC)

    With this property I can add this information to the infoboxes from Wikidata and it is used in more than one Wikipedia. I looked for properties that can be used to store that value but couldn't found any. -- Agabi10 (talk) 19:50, 31 October 2015 (UTC)

The label should be something more broadly applicable, such as 'jersey number' or maybe even 'competitor number', and the allowed values should be expanded to allow for 00 or larger numbers that are used in some sports. Thus we can avoid having a property like this for every sport. Joshbaumgartner (talk) 09:44, 9 May 2013 (UTC)

    Varietals aren't "genres" and that is the closest thing I can find to what would fit for listing types of grapes, fruits, or herbs used to make wines, liquors, beers, ciders, etc. This is my first time requesting a property and I'm unsure on if I did it right, but, perhaps others interested can help improve this request. Thank you for your consideration. SarahStierch (talk) 17:18, 6 July 2014 (UTC)

    Pictogram voting comment.svg Comment: Sarah, could you give an example of how you see this property being used in a Wikidata statement? For something like Zinfandel (Q204433), we might be able to build a set of varietals with existing properties, e.g. "Zinfandel use (P366) varietal". Other useful statements might be "Zinfandel instance of (P31) cultivar", "Zinfandel subclass of (P279) Vitis vinifera". That instance of and subclass of usage would be consistent with how Wikidata classifies cats and dogs, e.g. Chihuahua (Q653).
    Anyhow, food and drink is an interesting area for structured data. Let me know if the above makes sense or if you have other ideas about how to model things. Cheers, Emw (talk) 19:59, 6 July 2014 (UTC)
    Hi User:Emw! Hmmm.... I'm not really sure actually...I'm pretty open minded and didn't give that aspect much thought outside of wanting to be able to use "varietal" as a statement. I'm not too sure...I can see the cultivar and vitis vinifera probably working best as statements versus the first varietal - but, since Zinfandel is a varietal, and it's a type of vitis vinifera.....hmmmm.... I'm leaning towards your experience in this to guide me! SarahStierch (talk) 20:06, 6 July 2014 (UTC)
    Sarah, things like "Zinfandel" are tricky because they're polysemous. As you you say, Zinfandel is a type of wine and a type of grape. However, many statements for Zinfandel wine are false for Zinfandel grape, and vice versa. For example, Zinfandel wine is not susceptible to bunch rot and Zindandel grapes do not have an alcohol by volume range of 12-17%. The wine derives from the grape. I think these statements illustrate the need for two separate items for the two different senses of Zinfandel.
    This kind of polysemy exists elsewhere, e.g. with the concept "influenza". Influenza is formally a type of disease, but it is often also used to refer to a type of virus. Separating the two concepts into two Wikidata items -- influenza (Q2840) and influenza virus (Q287246) -- allows us to be much more precise and expressive about each subject.
    Perhaps we could do the same here with Zinfandel wine and the Zinfandel grape it derives from. That is, we could reserve Zinfandel (Q204433) for the grape and create a new item Zinfandel wine (Qx) for the wine. What do you think? Emw (talk) 00:29, 7 July 2014 (UTC)
    User:Emw you are a genius! (But you probably knew that already). Making new items for wine is a GREAT idea. How do we make that happen. SarahStierch (talk) 01:59, 8 July 2014 (UTC)
    @SarahStierch: I have started Wikidata:Property_proposal/Natural_science#fruit, I think the first step would be to start creating items for the fruits and linking them with their plants.--Micru (talk) 12:33, 17 August 2014 (UTC)
    @Emw, SarahStierch, Micru: You are absolutely correct about the need for multiple items for Zinfandel (Q204433). It is all in one Wiki article, but Zinfandel wine and Zinfandel grapes are separate and distinct concepts, so if there is data that applies to one and not the other, then they certainly need a new item. It can even be appropriate to give the wine and grapes each their own new item, while retaining the original Zinfandel (Q204433) to cover the general concept of Zinfandel, inclusive of both the wine and grapes, that is discussed in the Wiki article. We currently have material used (P186) (alias ingredient) that can link the wine item with the grape item. Josh Baumgartner (talk) 22:46, 30 October 2015 (UTC)

    @SarahStierch:  Not done This is a valid use-case, but we already have material used (P186).
