Symbol support vote.svg Support. I guess "decimal value or decimal approximation" would be a more correct label but that sure sounds nerdish. About the number of digits, I think we should give as many as possible (depending on the number of digits allowed or the minimum value allower for the precision parameter. Note that we can diistinguish between decimal values and decimal approximation depending on the whether the precision is set to 0 or not. --Zolo (talk) 18:22, 10 February 2014 (UTC)
Symbol support vote.svg Support, we can have several approximation, the precision value will give the interval in which the constant is. I think we can also have an aproximation algorithm or formula property to give the way to calculate the approximations or the formulas that gives the values of the numbers. TomT0m (talk) 18:42, 10 February 2014 (UTC)
@TomT0m: not sure how we should do approximation algorithm. It seems difficult to do it directly in Wikidata. It would have to be a string, but length is limited to 400 chars and we would need to clearly define the syntax we need to use beforehand. One possible solution: pi (Q167): newproperty:numerical value computable through: Leibniz formula for π (Q306467). And then Leibinz formula could be defined on an external page. We could link to the external page using described at URL (P973) or a new, more restrictive, property. We could even ensure that some external pages are machine readable by requiring it to be in code and add a qualifier to specify the language. --Zolo (talk) 19:35, 11 February 2014 (UTC)

This property could be used similar to architect, where a painter decorated a building or main part of it - Oursana

If we have a "painter" property we would need to use it for simple paintings as well (if we have a "painter" property it would be odd not to use it on Mona Lisa). And it means that we would need to deal with potentially many properties (painter, sculptor...) while in most cases, creator (P170) alone is clear enough. I would prefer to use p170 with qualifiers (either part of (P361) or a new "role" qualifier), as suggested in this model that Marsupium has pointed to in Wikidata_talk:WikiProject Visual arts/Item_structure#Creator option problem. --Zolo (talk) 09:22, 5 December 2013 (UTC)
Zolo, your first link is a dead link. And it has nothing to do with your example of Mona Lisa. I mean cases where the painter is not creator (P170). I was inspired by architect (P84) which is also inconsistent to what you wrote above. I had in mind Tornabuoni Chapel (Q2593098) and we need to add Domenico Ghirlandaio (Q191423). I did not dare to use creator (P170), because he is not creator (P170) from the chapel but from the frescos. I do not see how to solve it with your suggestions. Or shall use creator (P170) for Domenico Ghirlandaio (Q191423)? --Oursana (talk) 22:59, 5 December 2013 (UTC)
Symbol oppose vote.svg Oppose I think this is a very bad idea, sorry ;), but it is not a nice solution to make a painter property refer to things inside a building in opposite to creator (P170) which would only be used referring to the item itself. We should solve that problem by ignoring the problem and add the very general creator (P170) to Tornabuoni Chapel (Q2593098) (I think it is enough general to do it and we can add qualifiers as Zolo pointed out) or create an item xyz for the frescos and state: <xyz> creator (P170) <Domenico Ghirlandaio (Q191423)>. <xyz> isLocatedIn (I don't know which property Tornabuoni Chapel (Q2593098). I agree with Zolo that we should not create a painter property without adding it to the Mona Lisa.
Apart from that the {{Property proposal}} should perhaps be filled with English text to facilitate non-German-speaking users to contribute. And anyway the multilingual text does not seem to be appropriate. Finally Wikidata:Property proposal/Place seems to be the false property proposal page. --Marsupium (talk) 17:43, 6 December 2013 (UTC)
Sloppy copy-paste sorry the link is fixed, and I meant applies to part (P518) not part of (P361) What I meant with qualifiers was something like:
or
I know it is different from Mona Lisa, but if we have a "painter" property it would be strange no to use it every time the creator is the painter (we use 'architect' every time the creator is the arhitect).
The text in German is here because it is automatically added by the property-proposal pre filled form (I think we should try to enhance it but that is probably not the best place to talk about it ;). --Zolo (talk) 18:34, 6 December 2013 (UTC)

@Zolo: I can agree with this but I also do not see the need for architect (P84), also there creator (P170) with qualifier would be sufficient.

This is the wrong example for my purpose. The Tornabuoni Chapel is most famous for the fresco done only by Domenico Ghirlandaio.--Oursana (talk) 11:07, 14 December 2013 (UTC)
OK, we should perhaps find a way to state that, the part a chapel is famous for, I am not sure, perhaps. But this additional property is surely not a clean way to do so. Can we close the discussion, Oursana? (Can I unwatch the page? ;)) Regards, --Marsupium (talk) 18:25, 30 December 2013 (UTC)
@ Marsupium: Yes, we can close the discussion, perhaps I will ask you again, when I try to express this. --Oursana (talk) 23:44, 5 January 2014 (UTC)
Symbol oppose vote.svg Oppose We have to separate the paintings from the building. And link the painting to the building with the property "part of": if different painters worked on the paintings the above solution is a nightmare. Building and painting as well specific parts of the building need different items. It is the only solution if we want to be able to add more data about the painting like style, date of renovation or destruction. Snipre (talk) 19:02, 30 December 2013 (UTC)

@Raoli: Corrected copy-paste error: visitor per year (museum) or number of users per year (railway line) are the same concept so is it possible to find an unique property for both uses instead of creating two differents properties with the same concept but using different definition ? Something like attendance. In french we have one word which can be applied in the two cited cases: "fréquentation" Snipre (talk) 18:59, 15 January 2014 (UTC)
@Snipre: Yes, it's not a problem for me, it seems a good idea en-"attendance", fr-"fréquentation", it-"frequentazione", but I would add "per year", eg: en-"attendance per year", fr-"fréquentation par année", it-"frequentazione per anno" or en-"yearly attendance", fr-"fréquentation annuelle", it-"frequentazione annua".

Moreover, the transportation property is "per day" and this property was proposed "per year". How would you merge that? I guess that the number of people who ride the said line in a year is an enormous number. Moreover, what would it mean to take the maximum for this merged property? This will be the most visited museum or transportation road; is this somehow meaningful?

Symbol oppose vote.svg Oppose. I agree that 'instance of' should not be used as a qualifier, but I question the need for such a qualifier in the first place. More specifically, I am concerned that this property will encourage poor separation of concerns in properties. In particular, the "Chelsea Manning (Q298423) sex or gender (P21):female (Q6581072), => gender identity (Q48264)" example seems problematic; more on that here. Also, please put more explicit information in the examples; it's inconvenient to trace down the background on the mentioned properties. Emw (talk) 15:48, 15 December 2013 (UTC)
Emw; I think we need qualifiers for some properties and this property would help us effectively separate concerns without needing a million specific properties. Filceolaire (talk) 16:28, 26 December 2013 (UTC)
Filceolaire, I agree that we need qualifiers in general, but I think this particular qualifier has a few issues:
  • It would not be in line with Semantic Web standards
The proposal indicates this qualifier would be a mechanism to create subproperties. Subproperties are properties. Subproperties are defined in OWL and RDFS by making a statement in the property definition like we do with 'domain' etc., not in statements in property usages in items.
Qualifiers, as far as I can tell, are already outside the scope of the web standards (Did I miss something?) Subproperties are in the semantic standards but are not supported by wikidata. The day that wikidata starts supporting subproperties (and searching accross a property plus it's subproperties simultaneously) I will support replacing all of these 'specifically' subproperties with specialised properties where we can use the subproperty mechanism to search accross all of these at the same time. Filceolaire (talk) 00:42, 30 December 2013 (UTC)
Filceolaire, qualifiers are not officially supported in W3C standards, but they have been given some thought: see Defining N-ary Relations on the Semantic Web. On the other hand, subproperties have been officially supported in Semantic Web standards, including those for queries, and reasoning engines as rdfs:subPropertyOf for almost a decade.
The fact that subproperties are defined in Semantic Web standards is in itself a very strong reason to structure them as closely as possible to those standards on Wikidata. rdf:type and rdfs:subClassOf are defined in Semantic Web standards but not in Wikibase, yet we structure them as closely as possible to those standards in P31 and P279 -- debates on those properties revolve around their semantics as defined in the standards.
W3C standards define a subproperty as a property of a property, not a property of a property instance. In other words, anyone wanting to use a subproperty would use it as a parameter of Px as we define them in property documentation templates -- not as a qualifier of an instance of Px as used in a statement. We have established practices for modeling these property parameters in Template:Property_documentation. Emw (talk) 02:00, 3 January 2014 (UTC)
  • It would make constraints and semantic reasoning difficult or impossible
This point is closely related to the one above. By departing from Semantic Web standards, we also make it more difficult or impossible to deal with constraints. For example, if we say "Moulay Ali Cherif relative: Al Hassan Addakhil, type of kinship: ancestor" (example taken from Property_talk:P1039), then how do we ensure that the 'ancestor' subproperty of 'relative' fulfills constraints? (And why not just use 'ancestor'?) Even if we can express constraints this way in Wikidata's in-house constraint handling system, how would we represent these constraints in OWL when subproperties are defined in qualifiers? Emw (talk) 17:06, 28 December 2013 (UTC)
For the specific example you gave here: 'ancestor' is a subclass of 'relative'. That's what the constraint should check for. when we have implemented queries we can look again at whether this structure is, or is not, a problem. Filceolaire (talk) 00:42, 30 December 2013 (UTC)
Reinventing the wheels of the Semantic Web is perilous. A protocol to verify subproperties based on corresponding class definitions is a neat idea, but it ignores conventions ubiquitous in the rest of the world. Subproperty semantics and entailment as defined in RDF model theory and SPARQL have well-known computational properties and a large toolchain to support inference and querying. Adopting W3C conventions will let us build up support for subproperties above and outside Wikibase now -- as we do reasonably successfully for constraints, queries and class hierarchies -- while also being as closely compatible with the rest of the Semantic Web as possible. Emw (talk) 02:00, 3 January 2014 (UTC)
  • It would be a way to create new properties without community review
Since subproperties are properties, this qualifier would be a way to create properties without input from other Wikidata editors. Having a formal property proposal helps ensure new properties are well-defined, not redundant with existing properties, known to relevant interest groups, etc.
This one isn't a bug; it's a feature. Our property approval process is quite time consuming. Being able to create specialist subProperties, without having to go through that process, is, I believe, a good thing. We already have a number of other mechanisms for doing this e.g. the 'significant event (P793)' property. Filceolaire (talk) 00:42, 30 December 2013 (UTC)
Then let's set up a streamlined process for creating subproperties the right way. I don't think anyone contests the fact that properties like significant event (P793) are innovative solutions, but my concern here is that they are not nearly as robust as solutions from W3C standards, and will have a long-term effect of making Wikidata an insular project in the Semantic Web -- or further fragment the Semantic Web. The further we drift from those standards, the harder it will be to import and export to other Semantic Web projects, and take advantage of the edge-cases solved and compelling tools built for such projects. If bureaucratic slowness is preventing useful properties and causing us to implement non-standard workaround solution, then let's cut red tape so we can hew closely to standard solutions.

Looks like valid objections to me. -- Lavallen (talk) 18:41, 28 December 2013 (UTC)
Remember that even if this property is not created then these informal sub-properties will still continue to be created. They just won't use this specialist property; they will use 'instance of' and other properties instead. Filceolaire (talk) 00:46, 30 December 2013 (UTC)
The semantics of instance of (P31) are those of rdf:type. Thus, using P31 to define subproperties is incorrect. Emw (talk) 03:19, 3 January 2014 (UTC)
Pictogram voting question.svg Question With the current updates from the sex or gender discussion, is it worth revisiting this property for use instead of instance of (P31) for, for example, specifying that a particular 'sex or gender' statement is specifically about gender identity (Q48264)?

Example plant (Q756) disjoint with animal (Q729)
Source reliable sources
Proposed by Emw (talk) 14:33, 4 January 2014 (UTC)
Class A is disjoint with class B.

This property would let us state that two classes are disjoint. It would have the semantics of owl:disjointWith. It is closely related to proposed enhancements for property parameters currently being discussed.

Disjointness is inherited. For example, if plant (Q756) disjoint with animal (Q729) and mammal (Q7377) subclass of (P279) animal (Q729), then mammal (Q7377) disjoint with plant (Q756). And, because David Bowie (Q5383) instance of (P31) human (Q5) and human (Q5) 'disjoint with' plant (Q756), we know David Bowie (Q5383) instance of (P31) plant (Q756) is incorrect.

Disjointness is how the Semantic Web knows that David Bowie is not a plant. "But", you might say, "David Bowie is a human, and human is not declared as a subclass of plant, so we already know he is not a plant." Surprisingly, that is not the case. This is because the Semantic Web operates on the open world assumption (OWA), which is described nicely here. Disjointness in the Semantic Web is also explained well here and in slides 5-7 here.

First: it's a bad example. Second: How does this property supports us providing useful data for infoboxes? --Succu (talk) 18:45, 4 January 2014 (UTC)
Hi Succu, to understand better what is as sake here see hte Wikimedia grant by Markus Kroetsch, one of the maker of this project here. Wikidata is an ecosystem for which infoboxes are only a part of the truth. TomT0m (talk) 19:04, 4 January 2014 (UTC)
I know Markus, I know his grant - but you did not answer my question. --Succu (talk) 19:10, 4 January 2014 (UTC)
OK, then the answer is "it's not supposed to add any data in infoboxes". It's just another way to express constraints (like) such as one of, domain, range ...
Question: Both plant (Q756) and animal (Q729) are organism (Q7239). David Bowie (Q5383) is a organism (Q7239) is valid to. So why should I regard plant (Q756) and animal (Q729) as disjoint. --Succu (talk) 19:17, 4 January 2014 (UTC)
Because the organism class itself is not constrained. This statement just says, if it's a plant, it's not an animal, and converse. It does not say that if it's a plant it's not an organism. TomT0m (talk) 19:24, 4 January 2014 (UTC)
So what is necessary to be him not a bacteria (Q10876) or mineral (Q7946)? --Succu (talk) 20:05, 4 January 2014 (UTC)
To every instances of organism, it is enough to state that, as plant is a subclass of organisms, that (living) organisms are disjoint with minerals. For bacteria, we should look a bit closer to the subclass relationships beetween them. Any idea you could have ? TomT0m (talk) 13:18, 5 January 2014 (UTC)

Klortho, if this is a „no-brainer“ then how will you source such claims? --Succu (talk) 20:40, 4 January 2014 (UTC)
Well, I don't think opinions on talk pages have the same sourcing requirements as articles (or items), but I take your point that "no brainer" is an overstatement. From my perspective, it seems like an obvious choice to add because it's a pretty fundamental part of the OWL standard, and very useful for machine inferencing. You asked about infoboxes before, but keep in mind that that's just one of the use-cases for Wikidata, and a human-oriented one. While it is obvious to humans that "plant" and "animal" are disjoint, a machine couldn't make that assumption by itself. Statements using this property would be helpful to support queries using negation, like (a bit contrived) "list all the non-animal things that are native to Maryland".

Pictogram voting comment.svg Comment this property can be useful as you told, but for big hierarchies could be difficult manage this: if I understand correctly, every item of a hierarchy should has statements of this property with the other items of the hierarchy itself. Is not complicated? --Paperoastro (talk) 15:03, 5 January 2014 (UTC)
How to use it is probably an open question, but I don't think it's a good reason not to have this property. We will figure out how to use it properly, and having a systematic rule to add it every time it is possible to do this might not be a good idea, maybe we could have a put it when somebody has identified a concrete problem that actually occurs policy, or when it's useful for some tool for some reason,I don't know. TomT0m (talk) 15:22, 5 January 2014 (UTC)
I don't think this is right: "every item of a hierarchy should has statements of this property with the other items of the hierarchy itself". The example User:Emw gave is a good one. "plant" and "animal" are part of a large, complex hierarchy, but you gain a lot even if all you do is to add one statement that they are disjoint sets. Then you know that every subclass of plant is also disjoint with animals (and every subclass of animals), and that any instance of plant, or any instance of any subclass of plant, is not an instance of (any subclass of) animal. And so a machine could deduce that a rose is not a cat, or (reiterating the example above) that David Bowie is not a plant. If more "disjoint" statement were added, at other levels of the hierarchy, of course that would be helpful, but not necessary. Klortho (talk) 01:31, 6 January 2014 (UTC)
That's true if we have a real tree, with disjoint leaves and in which each class at the same level are also disjoint. It's not the general case though. Maybe it would be easier to manage with an nary equivalent, owl all disjoint classes, with the list of disjoint subclasses as a qualifier of the statement in their parent leave. Or some higher level way to tag all classes of a whole tree as a hierarchy with these properties, with an item for the hierarchy itself. TomT0m (talk) 11:47, 6 January 2014 (UTC)
EDIT: Actually I was looking for DisjointUnion which is stronger and better in the case we know every subclasses of some hierarchy : Not only the subclasses are all disjoint, but the union of the listed subclasses is their parent class in the tree. TomT0m (talk) 19:05, 6 January 2014 (UTC)
I think we should to be aware of the implications and discuss them first. So I have a question. Assumig a family (Q35409) with five genus (Q34740) G1, G2, G3, G4, G5: how do I express they are disjoint to each other? --Succu (talk) 14:22, 6 January 2014 (UTC)
Did not see your comment, but my answer above is a good answer to your question, you say the class corresponding to your family is the disjoint union of the G1, G2, G3, G4, G5 classes. With the bonus that every instances of your genre is an instance of exactly one of the G1 ... G5 classes, no more, no less. TomT0m (talk) 19:09, 6 January 2014 (UTC)
TomT0m, so we need another property DisjointUnion? I'm I right that this property needs to know all affected genra? --Succu (talk) 20:54, 8 January 2014 (UTC)
Absolutely. If we are not complete about the gena, we should use AllDisjointWith (that's 3 properties), who just says that no individual is an instance of two of any G1...G5 pairs. TomT0m (talk) 21:30, 8 January 2014 (UTC)
Instances of taxa are rare. Recently some authors regarded some species of the formerly of AllDisjointWith genus Aloe (Q127134) as disjoint and established the new genera Aloidendron (Q13539278) and Aloiampelos (Q13539282). So how will we reflect this? --Succu (talk) 22:14, 8 January 2014 (UTC)
I see this as a separate discussion, that doesn't really address the usefulness (or not) of the "disjoint with" property. Whether or not an AllDisjointWith or DisjointUnion property gets defined in the future, this simple binary disjoint with property would still be useful, wouldn't it?

Since disjoint with is reciprocal, presumably the other ten could be inferred (automatically). Klortho (talk) 02:52, 15 January 2014 (UTC)
@Klortho: No, we would need an order of n² statements, the realation is not transitive as an equivalence relation. If <Bob> is not <Jessy> and <Jessy> is not <Bob>, we can't deduce that <Bob> is not <Bob>. This is true for an equality relation (an equivalence relation, symmetric, transitive and reflexive), not for a not equal relationship. That's why the n-ary AllDisjointWith property is interesting in such cases (we could express the list of arguments with qualifiers instead of like OWL does with a list of statements). TomT0m (talk) 12:05, 15 January 2014 (UTC)
Yes, that's right: order of n². Here, n=5. The number of statements is the (n-1)th triangle number. The 4th triangle number = 10. I didn't say transitive, I said "reciprocal", by which I meant (using your terminology) "symmetric". If <Bob> is not <Jessy>, then <Jessy> is not <Bob>. I agree that an n-ary AllDisjointWith property would be useful, but the point I'm trying to make is that the statements can be done with a single "disjoint with" property. And the broader point, in answer to User:Succu, is that this "disjoint with" property is useful, whether or not an n-ary AllDisjointWith property is ever implemented. 130.14.9.92 18:13, 15 January 2014 (UTC)
OK, lets us assume that genus Aloe (Q127134) consist of 500 accepted species (the actual number is a little bit higher). Than we need 124,750 statements. Assuming further a single new species is described. To make clear this species is destinct from all the others we have to add 500 more statements. A lot of statements to make clear what is clear by taxonomic defenition. --Succu (talk) 18:41, 15 January 2014 (UTC)

Sorry to beat this dead horse, User:Succu, but I guess I still don't see why the fact that this property is not powerful enough to handle that use case means that we shouldn't have it at all.

To be consistant we have to put all "not a ..." or create a new set of rules that will be difficult to apply. If the structure of "instance of" and "subclass of" is well done, you can define all the definitions which can be applied to an item by recursion and by definition all the rest can't be applied to your item. If you choose to define item with what they are and what they aren't, you have to cover all cases. If you choose to define the items only by what they are, by reasoning you can assume what they are not. Snipre (talk) 23:00, 6 January 2014 (UTC)
That's wrong, read the discussion. We have efficient solutions to manage that, see the discussion above. Plus the close world hypothesis you advocate for is probably not a good idea in a very open database like this one. I don't think for example we can deduce that James Bond car is not red because we know nothing about its color in the database. TomT0m (talk) 23:31, 6 January 2014 (UTC)

Comment: My initial impression of "disjoint with" is that it should only be used to say that two classes which share the same parent class should be linked. In other words, two species which share a genus might have the statement, whereas a genus in one family as opposed to a genus in a second family (with both families in the same order). What would have the disjoint with statement in this latter case would be the two family statements; then it is implied, as disjoint with is an inheritable statement, that the two genus are disjoint with each other.

At that case then, you can say that living thing is disjoint with non-living thing, and thus you never need to make the statement organism disjoint with machine, because there are no machines (currently) that we call machines that are both living and non-living.

Since we're on that topic then, would we actually say that living thing and non-living thing are disjoint if we know of the existence of cyborgs (or at least can imagine such an idea), for example? Or of certain organic and non-organic systems which are harvested to create energy such as an algae solar pool? How does disjointedness interact with qualifiers, such as a ship being first termed a destroyer and then later in its life a battleship? How does it interact, as is common in biology (and I'm sure elsewhere), that certain taxa are organized and re-organized and sometimes end up in two disjoint groups? --Izno (talk) 00:14, 7 January 2014 (UTC)

"How does disjointedness interact with qualifiers, such as a ship being first termed a destroyer and then later in its life a battleship?"
Being an instance of two disjoint classes at the same time would make Wikidata inconsistent. If a ship was a destroyer and later transformed into a battleship, then I do not see that as inconsistent. This suggests that when reasoning with disjointness, we need to account for temporal qualifiers in rdf:type. Perhaps we could do this by ranking P31 claims so that the most current claim is ranked higher than P31 claims that are no longer valid. Emw (talk) 12:17, 7 January 2014 (UTC)
We also have to take into account sources in some way then; example, some sources will express that item A is of type B according to sources D, E, and F, while item A is of type C according to sources G and H, where types B and C are disjoint. Real world example: there is a ship (class?) in the Swedish Navy which according to the Swedish Navy is classified as a patrol boat, while other navies and sources consider it to be a frigate. Ranking may be one solution to this, but there will be other cases where there is no highest-ranked type but instead two or more types ranked of the same highest level (i.e. "preferred" in Wikidata). What then? This is the same type of question I levied about taxa, I suppose, but ships are another convenient one to pick on. :) --Izno (talk) 20:30, 7 January 2014 (UTC)
I don't understand why this would be an issue peculiar to this property. Isn't it true that you can always have contradictory statements in Wikidata, each of which have different sources? Klortho (talk) 03:37, 10 January 2014 (UTC)
Absolutely. I'm just asking what "disjoint with" means on a particular item's page when that's the case. --Izno (talk) 17:01, 11 January 2014 (UTC)
Symbol oppose vote.svg Oppose. All species are disjoint with other species and the same for other taxon ranks so this property is no additional info in those case.

Template:Filceolaire This information is good both for inferencing and for consistency checks (therefore). It's no information added because you know those classes are disjoint, but a machine whould not know it unless we tell him. It would for example be not a problem that a pig is noted as both a pig and a plant. If we want that a machine and a reasoner catch this, we will have to inform it, give him a hint.

I don't know in English, but in Italian we have onorificenza (that is an award conferred to a notable personality following his career or merits; for example, in sports there is Star of Sports Merit (Q3972928)) and "titolo sportivo" (that is gained as a result of a sporting competition). For example, Pietro Mennea (Q5444) has the "onorificenza" Commander of the Order of Merit of the Italian Republic (Q14539729) and won the title ("titolo sportivo") of Olympic champion in 200 meters. I think they are different things. -- Yiyi .... (talk!) 15:50, 29 November 2013 (UTC)
It sounds like onorificenza is still an award; who confers it? In Australia we have the Australian Sports Medal (Q1649458) which sounds similar, and you can see on Kevin Coombs (Q6396063). John Vandenberg (talk) 17:00, 29 November 2013 (UTC)
It's given by Italian National Olympic Committee (Q1114833). But, I repeat: I think they are different things, because a medal is given for ONE competition, while a "onorificenza" is an award given following a long carrer (like Pritzker Architecture Prize (Q133160) or Knight of the Legion of Honour (Q10855271)). -- Yiyi ....

Source reliable sources in line with Wikidata BLP policies
Proposed by Emw (talk) 05:51, 23 December 2013 (UTC)

P21 has been labeled 'sex' since February and has always listed restrictions in its description that indicate it concerns the biological sex of the subject. The property is used in almost a million items. Properties like mother (P25) and father (P22) have constraints based on the value of P21.

However, P21 doesn't handle the distinction between sex and gender well, making P21 statements about transgender people like Chelsea Manning (Q298423) complicated. One solution that has been proposed is to rename P21 from 'sex' to 'sex or gender' (which may likely end up being 'gender or sex'). A separate proposal would create separate properties for 'sex' and 'gender'. This proposal is intended as a wider review for the latter.

Both ideas have gotten support at different times from mostly non-overlapping audiences, including Sj, Shii, Maximilianklein, Bluerasberry, 朝彦, Jaredzimmerman_(WMF), Emw, Tobias1984, Ajraddatz, Avenue, Zolo, Arctic.gnome and Bever.

The proposed property includes both gender identity and gender expression (Q15404978). Human Rights Campaign defines gender expression as: "External manifestation of one’s gender identity, usually expressed through masculine, feminine or gender-variant behavior, clothing, haircut, voice or body characteristics. Typically, transgender people seek to make their gender expression match their gender identity, rather than their birth-assigned sex."

To avoid having redundant 'sex' and 'gender' claims in almost all Wikidata items about people, this property would not be applied for cisgender individuals. This omission would also apply to the alternative proposal. Here's a comparison:

Option A (this proposal):
sex (P21) male (Q6581097)
gender (Px) no label (Q15304678)
sex (P21) male (Q6581097)
Option B (the proposal discussed here):
gender or sex (P21) male (Q6581097) specifically sex (Q290)
gender or sex (P21) no label (Q15304678) specifically gender identity (Q48264)
gender or sex (P21) male (Q6581097)

Both of these approaches have advantages and disadvantages. Discussion of that is linked from the points listed here. In brief, Option A accepts the possibility of occasional false positive claims about a person's sex to preserve constraints for properties like 'mother' and 'father' that assume biological sex, and to keep a clean separation of concerns between what everyone seems to agree are separate properties. Option B ensures that we will have less-than-occasional false positive claims about a person's sex, but it weakens inferences we can make with properties like 'mother' and 'father', and does away with a clean separation of concerns.

While they differ significantly, both options acknowledge that we need a better way to structure data for transgender people. If this proposal doesn't get sufficient support, then we would go with Option B. I just wanted a final, wider community review of this alternative before we make a significant change to one of Wikidata's most popular properties. Emw (talk) 05:51, 23 December 2013 (UTC)

  • Symbol oppose vote.svg Oppose When you consider the fall out of ending the use of the "GND attribute", I hate to see another big change that does not come to a working conclusion. An alternate way of dealing with a "Chelsey Manning" case is to use qualifiers where a date is used to indicate such a change. Having another attribute to indicate a changed gender is imo not really useful. Being a father or mother is the indication of functioning sexuality. On a similar note, a eunuch is not really male either; he never reached puberty and therefore never became a functioning male. It is never considered in these discussions but we deal with them in Wikidata. Thanks, GerardM (talk) 09:59, 23 December 2013 (UTC)

There is a difference between being a parent and being a father or a mother. Parent indicates a role re upbringing of a child. Father / mother are typically the parents of a child. At the time of conception these people were sexually active and effective at that. As to this whole transgender issue what is the problem with using qualifiers to indicate this? GerardM (talk) 17:21, 25 December 2013 (UTC)
  • Symbol oppose vote.svg Oppose For most people we have no way of knowing whether their biological sex matches their gender expression and we never will know this. See the lengthy discussion at Property_talk:P21#Transgender_.2F_Cisgender_changes. Having a combined property accurately reflects this ambiguity. Where we do have more info this can be expressed using qualifiers. Filceolaire (talk) 12:07, 23 December 2013 (UTC)
  • Symbol oppose vote.svg Oppose for now. I think this one needs to be an RFC where we map out all variations and ensure we have a well documented structure. At present I prefer option B, as these are tightly entwined properties and if a person has undergone changes to either, the details and history of those changes are best kept in a single property. For most cases, a single value without qualifiers is sufficient. That means someone trying to use the data can request a single property and all qualifiers; if the result is a single item, use it; if there are qualifiers or multiple results, the reuser knows 'its complicated'. If we split sex and gender, all reusers need to request two properties and compare them to determine whether 'its simple' or 'its complicated'. The reality is if there are two properties, many reusers will only look at one, and will display the wrong result. FWIW, this may not be the politically correct method of encoding this data, and it doesnt encode all variations, but medical condition (P1050) => gender identity disorder (Q1049021) or transsexualism (Q190965) or hermaphroditism (Q7847568) and significant event (P793) => Sexual reassignment surgery (Q1053501) (with a date qualifier, and maybe a sex qualifier?) is one way to accurately record some important data items. See w:Gender identity disorder , http://www.genderpsychology.org/transsexual/icd_10.html , etc. John Vandenberg (talk) 17:01, 23 December 2013 (UTC)
John, I hadn't considered it that way, but I think your scenario could actually be seen as a disadvantage of Option B. It implies that users will need to include a nested query whenever they want to ensure they are dealing with statements only about sex or only about gender. And unless we decide to make the sex or gender statement preferred, having both properties in one multi-property seems like it would require users to add boilerplate code to all queries involving P21 in order to ensure they get a single statement value. That seems like it would raise the barrier to entry for querying demographic information in Wikidata.
Also, how do you figure that having biological sex and gender expression in two different properties means users are more likely to display the wrong result? Can you give an example of a wrong result you're thinking of?
How would constraints for properties like 'mother', 'father', 'brother' and 'sister' be handled with Option B? Do we have any examples of constraints based on qualifiers? Does OWL support constraints based on qualifiers? We have favorable answers for all of these with Option A, but I don't think we do with Option B. Emw (talk) 03:27, 24 December 2013 (UTC)
Most re-users don't want to make statements about only sex or only gender. Mostly they want to have one value: male, female, or 'its complicated'. The data re-user may drill into the 'its complicated' subset if it is significant within their dataset. An example of displaying the wrong result: If a person is sex: male and gender: female, if the data re-user only looks at 'sex', they will group them into the male bucket.
sex assignment is a "fact" in most cases - only parts of the world where there are poor birth records is it debatable what sex was assigned at birth, and for most people there is no debate as they and everyone else happily accepts their sex assignment at birth. For gender identity, it is complicated. The taxonomy of gender is in flux in science. The acceptance of gender complexity varies greatly across cultures. Re-users who do want to make accurate demographic queries will be defining their own buckets, with granularity and composition determined by their own needs, country definitions, or cultural biases. They need to check the qualifiers and the sources of each statement in order to associate trust-levels with those statements. Anyone doing serious demography will replace : gender=female (source: imported from Wikipedia) with gender=unknown. The year that sex/gender changes occur is also very significant (child vs adult), and each country can have its own age brackets to differentiate child-sexuality-adjustment vs adult disorders. Some re-users will only be interested in gender when a sex change has occurred. etc.
I don't understand the problem with mother & father. In Option B, a parent may have 'sex/gender' => ('male' [qualified],'female' [qualified]), in which case the constraint on father and mother will both work. It isnt possible to accurately constrain mother & father on sex or gender. Like sex/gender, mother and father are both state defined (birth assigned) roles and fluid personal-choice roles not constrained by sex or gender or by time. In humans, a biological male may expresses as female but behave as a father or be listed as a father on adoption papers because the country doesnt recognise them as female. But then the state recognises them as a female or they undergo a sex change, and they wish to be known as the mother. But maybe the child is old enough to reject the parents wish to be referred to as the mother. John Vandenberg (talk) 05:07, 24 December 2013 (UTC)
I think that's a reasonable position, though I disagree with a few points. For example, if a user is querying only sex and thus ends up grouping into the male bucket a person sexed male and gendered female, then I don't see how we can say that is necessarily wrong. If we're talking about a biographical infobox on English Wikipedia, then of course it is wrong in the sense that it would be a major editorial error of omission. But I don't see that as a realistic scenario. If biographical infoboxes on Wikipedia are interested in sex, then gender is almost certainly also relevant. So the main consumers of Wikidata would include both properties in their display. Option B requires users to do reasoning about two properties within the results of one property, which seems like it would be at least as complex as doing so within the results of two properties.
Your points about the complex definition of 'mother' and 'father' are worth considering when talking about constraints, as these properties are often used in introductions to the topic. See OWL 2 Primer: Complex Classes. For example, is a transgender (note: not transsexual) man a mother or a father, or both? If it's both, then we cannot say that 'mother' and 'father' are disjoint, etc. Emw (talk) 14:41, 24 December 2013 (UTC)

Motivation. The idea is to separate circumstances from the medical cause (cause of death (P509)), to provide more structured data. See the talk here: Property_talk:P509. In modern times the cause of death normally has a specific meaning, and is determined by a medical examiner, e.g. the coroner. So, let's not mix-up these two things.

Pictogram voting comment.svg Comment. I encourage users interested in this kind of data to read Documenting Death -- The Certificate and the US Standard Death Certificate. For even more detail, see the CDC's Physicians' Handbook on Medical Certification of Death. More detail on "manner of death", which I think would be a better label for this property, is available on pages 42 and 43 of that CDC document.
"Homicide" and "automobile accident" are widely reported as "cause of death" by organizations like the CDC (here) and WHO (here). As seen on the US Standard Death Certificate, though, they are slightly different concepts: "homicide" and "accident" would be specified as the "manner of death", whereas some disease or health problem (ideally, something with an ICD-10 code) would be specified as a "cause of death".
The death certificate of Michael Jackson (certificate, amendment) is informative here. It provides fields for "manner of death" (field 119 in certificate, filled in as "homicide" in amendment) and "how injury occurred" (field 124 in certificate, filled in as "intravenous injection by another" in amendment). It also shows "acute propofol intoxication" as the most immediate cause of death (field 107A, the closest match for our cause of death (P509) property) and "benzodiazepine effect" as "other significant conditions contributing to death but not resulting in the underlying cause" (field 112).
As a matter of modeling, I would capture this information in properties, not qualifiers, because qualifiers will not be queryable in the foreseeable future. Just order the properties in the UI so they're clustered together, like we do for 'place of death' and 'date of death', etc. I would support this property if it were relabeled "manner of death" and the documentation updated to indicate that it should have values limited to "natural", "accident", "suicide", "homicide", "pending investigation" or "could not be determined". Emw (talk) 05:13, 6 February 2014 (UTC)
Pictogram voting comment.svg Comment I see that the WHO are using the label Specified external causes of death rather than just cause of death, on this page here: Availability and quality of cause-of-death data for estimating the global burden of injuries. I think that Specified external causes of death is essentially the same as circumstances of death (circum- being similar to external). So, perhaps we should rename cause of death (P509) to internal cause of death, and call this new one external cause of death? Both of these terms seem to be in common use, one example here: Alcohol Prohibition and Infant Mortality (first paragraph). Danrok (talk) 01:01, 7 February 2014 (UTC)
Danrok, the WHO paper we're looking at here, Availability and quality of cause-of-death data for estimating the global burden of injuries, only considers external causes of death. That paper is narrowly focused and has about 20 citations. The landmark WHO publication The Global Burden of Disease: 2004 Update, cited over 2700 times since 2008, has some analysis on deaths by "external cause of death" (Figure 25, page 49), but it doesn't use the term as categorically different than "cause of death". The Depew paper you note is marked as a draft; it has no citations. None of these papers indicate that dichotomizing "cause of death" into "external cause of death" and "internal cause of death" is common in controlled vocabularies.
Google Scholar gives a rough basis for comparison:
The last phrasing, "manner of death", also has the significant benefit of appearing in a major controlled vocabulary, the US Standard Death Certificate. Manner of death includes external causes of death -- i.e., accident, suicide, homicide -- they're just high-level. Page 43 of the CDC Physicians' Handbook notes "Deaths not due to external causes should be identified as 'Natural'." The difference between "manner of death" and "cause of death" is specificity: the former has 4 broad classes (plus 2 for uncertain causes) and the latter gets a precise value. The death certificate of Paul Walker, an American actor, is a good example of where an external cause of death is listed as both the cause of death and manner of death, at different granularities: the cause was "combined effects of traumatic and thermal injuries" and the manner was "accident". With the rubric from the external causes WHO table, the cause of death would likely be captured in controlled vocabulary as an unintentional car injury (with a code somewhere in the ICD-10 range V40-V49) and fire (a code in X00–X19). The manner of death would be the broad cause accident (Q171558).
So all external causes of death are still causes of death. I don't think relabeling our "cause of death" property (P509) "internal cause of death" would be a good idea. "Cause of death" is a fundamental and universally recognized property in demography. It should be used to capture an underlying cause of death, using items linked to ICD-10 codes. If we want another related property similar to cause of death (P509), then I think structuring it only the lines of manner of death, which would include "natural cause", would be best. Based on the prevalence of the term in relevant literature shown above and its usage by a major health organization, I would label that property "manner of death", with alias "circumstances of death".

Ivan A. Krestinin, Secretlondon, Tobias1984, what do you think of using powerplant (P516) with qualifier no label (P992) => booster (Q741745) or space tug (Q1958838)?--Micru (talk) 11:50, 24 November 2013 (UTC)

Currently I would prefer your solution, possibly with using "instance of" as the qualifier. --Tobias1984 (talk) 17:53, 24 November 2013 (UTC)
I do not think that P516 is applicable for this case. This usage is equals to Benedict XVI (Q2494) <powerplant (P516)> Mercedes-Benz M-Class (Q849935). — Ivan A. Krestinin (talk) 07:53, 25 November 2013 (UTC)
But then it would be just easier to request a property for "launch configuration" and add all the data of the launch, and not only the upper stage. It would even be possible to use time and height qualifiers to reconstruct the whole launch. The term upper stage could be avoided by just giving the stages consecutive numbers. --Tobias1984 (talk) 14:00, 25 November 2013 (UTC)
You propose group some subset of properties. But currently we have no such functionality. Somewhere I seen request for some grouping elements, but it does not implemented now. No need to avoid this missing using qualifiers. Qualifiers was developed for another purposes. Now about upper stages: maybe you are confused by English name of this device. In English it has "stage" word in name. This confuses with rocket stages. But this is not part of rocket, this is separate device. It start its work after separation from rocket. It is developed and produced by different organizations. For example Russian upper stage Fregat (Q1453740) can be used with Ukrainian Zenit (Q1748964) rocket. — Ivan A. Krestinin (talk) 19:03, 25 November 2013 (UTC)
Ivan A. Krestinin: If you check the usage of p516 you will see that it is a common use. If you want a specific property for rockets, then "launch configuration" can be used.--Micru (talk) 18:51, 25 November 2013 (UTC)

Tobias1984, I think Ivan is right that the English name (upper stage booster) is misleading, because it is not part of the "launch configuration". A more appropriate name would be "payload deliverer" or "space tug" (reference), since it is the vehicle that once all the stages are gone, sets the payload into the right orbit (see this video by the end).--Micru (talk) 19:30, 25 November 2013 (UTC)

Pictogram voting comment.svg Comment This is different from connecting line (P81). connecting line (P81) is desired to be set as the physical line which runs through the station. There are cases (in Japan, for example), where many different services may run under the "offical name" of the same line. For example, the aforementioned Chūō Line (Rapid) (Q1191297) is a part of Chūō Main Line (Q1078110), the official name of the physical track. Its local counterpart, Chūō-Sōbu Line (Q1091295) is also under the same physical track. --Wanderer28 (talk) 13:42, 17 February 2014 (UTC)

  • Reopen with other rationale. Now we have writable and readable file format but what about its own file format, which isn't only a property for software but also for programming languages. The appropriate description would be: "Subject's own file format". Besides statements (like in Adobe Photoshop (Q129793)) will be usually duplicated, so what about merge these properties to Supported file format? Or, we can use writable and readable file format properties only if they're appropriate (e.g. software can only read file format) --Rezonansowy (talk) 19:14, 18 January 2014 (UTC)

This is especially needed for academic journals, and is essentially genre (P136) for academic output that is not artistic. It could be used for any education or research relationships. magazines also have a specialty, or subject area. I could not find a more generic property which fulfills this need; apologies if it exists and I didnt find it. main subject (P921) might be sufficient, however its description ('main topic of creative work') doesnt feel right for a publishing venue and also doesnt feel right for 'papers' which consist of little more than data or a proof (i.e. not creative). I would be happy with a very generic 'subject topic' property. John Vandenberg (talk) 12:46, 28 February 2014 (UTC)

Pictogram voting comment.svg Comment string 'Micru' may have a trust value to insiders, but it doesnt to an average Wikidata data consumer. Also we should design systems that mean it doesnt matter who added a piece of data-our processes should provide quality rather than the names of the people adding the data. If a responsibility/trust statement is going to have any meaning, it needs to link to an item that has properties that describe how responsible/trustable the person is (e.g. admin, trillions of edits). I think Wikidata will need to add a 'Wikimedia user' class eventually, and there are notable people that have website account on (P553) on Wikipedia, but it needs to be carefully planned.
I think it is more feasible to add a new source rather than qualify the 'imported from' statement. Maybe, a user who has verified a bot-created property can add a 'stated in <source>' or 'part of <database>' source, or a new 'exists in <database>' clause? They might also remove the 'imported from' clause as it has been replaced by a better/human checked statement. John Vandenberg (talk) 12:05, 5 December 2013 (UTC)

    Yes, but the numbers are not always published that way. If a source tells "5% unemployment" we cannot construct the number of unemployed and work force. -- Lavallen (talk) 06:42, 23 February 2014 (UTC)
    So, would you recommend not having a property for number of employed persons? Or just including redundant data? --Yair rand (talk) 13:26, 23 February 2014 (UTC)
    I say that this maybe isn't a number that can always be derived from two other. If a report tells that the unemployment in Foo state is 6%. What should we type here if we do not know the number of "unemployed"? In Sweden one of the systems for counting these numbers is that somebody call 1000 persons and ask if they have worked anything in the last 30 days. If 900 answer yes, then the unemployment is 10%. This does not tell anything about how many they are.
    Another way is to look for how many is registered in the unemployment-bureau and compare with the number of persons in the range of 16-65 years. Then is it possible to derive this number. (Both this methods have serious drawbacks of course, and the politicians tends to choose the method that gives them the best support for their ideas.) -- Lavallen (talk) 14:03, 23 February 2014 (UTC)
    Okay, so in certain cases one can't have the data on the unemployment rate entirely as the number unemployed and the size of the workforce. Are there any cases where one can't derive the number unemployed from the related statistics on unemployment rate and size of the workforce? --Yair rand (talk) 14:18, 23 February 2014 (UTC)
    It's up to the definition of "unemployed". You may have worked one single hour the last month and are therefor not counted as unemployed, but you maybe are still registrered at the unemployment-bureau. And you maybe are a student, occupied 10 hours a day at school, but you are maybe still registrered, because you want an extrajob or a job as soon as the school ends. And you maybe are seriously handicaped, so handicaped that you cannot visit the bureau and not even answer the phone when the Statistics call to ask if you have worked. Or you maybe worked, but for peanuts, since the municipality refuses go give you social aid if you do not do some charity-work. -- Lavallen (talk) 16:00, 23 February 2014 (UTC)
What you told about Sweden is the same as is used by en:International Labour Organization#Labour statistics (ILO). For example, de:Wirtschaft Deutschlands has the unemployment rate (Arbeitslosenquote) provided by the national statistics organisation (destatis) for january 2014, december 2013 and the number from ILO for december 2013. The en:Wikipedia uses the data from Eurostat. I don´t know if Eurostat has the same numebers as the national statistics organisations. fr:Wikipedia has no source and the data is from december 2012. Another possible datasource is the The World factbook. The CIA publishes data about the unemployment rate too, for example for Albania the latest data is 13% (2012 estimated) source. Therefore, we would need two qualifiers for this property: P585 (point in time) and P143 (imported from). --Goldzahn (talk) 00:24, 24 February 2014 (UTC)
I don't think we should use "imported from". IMO, we should have the organization providing the data using stated in (P248) and the definition used using criterion used (P1013) (we would need an item about the definition like "unemployed person according to ILO definition". For France, the most commonly used figure seems to be "person registered by Pôle-Emply, category:A", and for some reason, these data are usually provided by the INSEE, not directly by Pôle-Emploi. --Zolo (talk) 11:19, 24 February 2014 (UTC)
What do you think about the qualifiers used in Q8085? --Goldzahn (talk) 21:09, 28 February 2014 (UTC)
I have tweaked it a bit as Eurostat seemed to mean to things: that data were provided by Eurostat, and that is used Eurostat criteria. Apart from this, I think the unemployment rate should be between 0 and 1, not 1 and 100, and also that this sort of data should go to Austria (Q40), not economy of Austria (Q8085), even though that makes very long items. I see both logical and practical reasons for this. This is the unemployment rate of Austria, not the "unemployment rate of the economy of Austria" and we need to be able to find data about the unemployment rate of some place by directly querying the related item. If the unemployment rate about a small city is in the city-item, the unemployment rate of Austria in "economy of Austria" and the unemployment rate of the US in "US labor market", it is going to be hard to follow. --Zolo (talk) 04:31, 1 March 2014 (UTC)
I don´t know if it is alreay possible, but meta:Wikidata/Notes/Inclusion_syntax#Properties_of_different_items says, that it should be possile (someday?) to access a property of a different item. And, for example, en, de, fr Wikipedia article Austria doesn´t tell the unemployment rate. Another problem that I see: The Eurostat source has the data of 28 states. Is it possible to copy all this data from this first item to all the other items and change in a second step what is different? Because I would like to input all this data, but with as little effort as possible. PS: Could we link to this item on the discussion page of P1198 as an example how to use this property?--Goldzahn (talk) 05:16, 1 March 2014 (UTC)
Accessing other items is not yet possible. But when that will be possible, it will be simpler and more intuitive to access data from the Austria item in an article about the economy of Austria than the other way round. We also have data about the unemployment rate of many cities, but it would not make much sense to create an "economy of city X" item just for storing economic data that can be stored in the main item. Storing everything in the main item is more consistent and more predictable.
I do not think anyone has yet developped any tool for copying a whole statement from one item to the next. Economic data are big and need to be peridocally updated. A bot would certainly be useful, and given that they are usually available in a machine-readable format, that should be doable (unless we want to find copyright issues). --Zolo (talk) 05:48, 1 March 2014 (UTC)

Discussion

Needed to distinguish different shares of ownership.

I think proportion (P1107) is fine for this. That said, if we want to provide this kind of info in a really rigorous way, that is going to be a lot of work. We would need to determine exactly how we count (options, preferred stocks etc.) We can use several definitions in the same item, but that will make things real complicated. We also need to determine whether we count indirect participation. If X owns 20% of Y through its wholly-owned subsidiary Z, I think we should have "Y: owner: Z" but not "Y: owner X" so that percentages do not add up to more than 100%. But this sort of data is not always publically available. --Zolo (talk) 09:43, 24 February 2014 (UTC)
Different kinds of stocks makes it complicated, yes. It's common practice in Swedish newspapers to tell two numbers: 1. How large share of the capital. 2. How large share of the votes in the annual assembly. Golden shares do not exist here, so I do not know how that would affect. -- Lavallen (talk) 10:57, 24 February 2014 (UTC)
proportion (P1107) seems usable! But it is almost impossible to found, as it is not listed at any list of properties.
In some case (preferred stocks, multiple stock classes) in can be complicated, but having a little inaccurate proportion (P1107) is still much better than current nothing (without qualifier). This sort of date is publically available for most of the public companies. --Jklamo (talk) 12:53, 24 February 2014 (UTC)

  • Symbol support vote.svg Support This sounds awesome if datasets exist which report numbers in this way. I know nothing about this kind of epidemiology reporting but it seems sensible. I support this being created, but I suppose that I should ask for a link to a dataset or research paper which presents this kind of data. Having a link to this data would prove that this is a value which already has a history of use. Blue Rasberry (talk) 02:28, 11 January 2014 (UTC)

  • Support. The constraint should be number between 0 and 1, and I think this is a generic property (essentially it is probability (Q9492), not strictly medicine, natural science or even science, which IMO should be accompanied with a 'population' qualifier to an item that defines the population. In chemistry, one example use is isotopes; e.g. what is the prevalence of carbon c-14 (Q840660) in a population of carbon (Q623) obtained from <process>? Compounds, etc also have prevalence relationships recorded by earth/environmental scientists. In pure mathematics, there is mathematical analysis (Q7754), which there is empirical prevalence data before there is a theory to define it. e.g. how frequently does a specific random number generator produce a prime? Even regarding epidemiology, which has such wildly different accuracy rates, the population and study method would need to be defined by many qualifiers if the 'population' isnt an item with its own properties. e.g. We also need to be concerned about multiple species having a relationship with a disease, and different types of relationships: e.g. Disease carrier (Q5282118). e.g. Does malaria (Q12156) => 0.000123 qualified to the UK mean prevalence among humans in the UK .. or rats or sparrows, etc? What method was used to create the sample population from the target population? (is it citizens only?) There is also the relationship between Anopheles (Q158597) and Plasmodium (Q130948) can also be a use of a prevalence property: what percentage of the mozzies in a defined area are carrying the parasite..? @Bluerasberry:, NGOs like Cancer Council and disability organisations have this type of data for their respective domain. I expect Centers for Disease Control and Prevention (Q583725) will have large stockpiles of this data. Australian Bureau of Statistics (Q123347) definitely keeps statistics for diseases of national interest. John Vandenberg (talk) 09:09, 1 February 2014 (UTC)
I would support, but as usual I would like the documentation / examples nailed down a little better. I don't understand the examples "country (Q6256) => United Kingdom (Q145)" or "population => male infants". What are "country" and "population" supposed to be? Qualifiers need properties in those positions, right? If these examples aren't realistic, then they should be dropped from the template. Klortho (talk) 03:37, 2 February 2014 (UTC)

  • Pictogram voting comment.svg Comment This could be a very interesting property, but I'd like to be sure to understand the meaning. In the Template:Infobox spaceflight, in the section Main telescope, there is the parameter telescope_wavelength. Do you intend this with this property? --Paperoastro (talk) 00:16, 20 December 2013 (UTC)
  • I think this should be just the property for sending and receiving information. But we should also draft a request for "telescope wavelength". We could also generalize it to any scientific instrumentation. A medical x-ray machine for example detects x-rays. But x-ray machines probably are hooked up to a computer today, so they don't need a property for sending and receiving signals. On the other hand this property can also be used for cell phones, radios, antennas etc... --Tobias1984 (talk) 08:39, 20 December 2013 (UTC)

International number. John Vandenberg (talk) 09:07, 6 March 2014 (UTC)

There is also a GTIN-13 compliant ISMN format (like ISBN-13) which starts with 979-0- instead of M-. Im not sure whether we need both as separate properties, or which we should use if we only have one property (probably the GTIN-13 format) John Vandenberg (talk) 10:17, 6 March 2014 (UTC)

Despite it's name ISMNs do not for musical works but for (editions of) notated (i.e. sheet) music. cf. ismn-international.org. Thus your example above is wrong. ISMNs are a nice international identifier but I doubt whether wikidata will have any items which could carry this property. Does anybody know if ISMNs are retrospectively created for old publications and wether digitizations of sheet music get an ISMN of their own (I can imagine a property version of Editio princeps (Q1249682) which then could be qualified by its ISMN). -- Gymel (talk) 17:33, 6 March 2014 (UTC)

I did state in my example that it was wrong. Anyway, I have now given a proper example, and as you can see ISMNs are given to works that pre-date the ISMN standard - it may only be reprinting that triggers an ISMN being allocated. New compositions which are Creative Commons/Public domain may also be published and thus be allocated ISMNs. Wikipedia already has many articles about notable published compositions, however Wikidata doesnt require a Wikipedia article - Wikidata should have edition items that record the history of a work - the sheet music items wouldnt meet Wikipedia notability criteria, however they would be recorded/described in the Wikipedia article about the work. The ISMN property would also be used in sources items. Wikisource sheet music transcriptions are another source of data items. John Vandenberg (talk) 20:56, 6 March 2014 (UTC)
Still an wikidata item about a work and therefore not suited as an example. The linked en:Three Bagatelles (Ligeti) however displays a reference to the Schott edition with ISMN 979-0-001-11903-0 (improperly attributed as ISBN) as source for the list of movements. Thus:

I see this was previously proposed at Wikidata:Property proposal/Archive/16#International Standard Musical Work Code (en) by User:Pigsonthewing, but not implemented because catalog code (P528)/catalog (P972) could contain this information, with the option of re-opening it. These are international codes; not codes that are specific to one of many catalogs. John Vandenberg (talk) 10:07, 6 March 2014 (UTC)

This is definitely about musical works (Also arrangements and adaptions of works, individual movements or collections). As I understand this is a vehicle for copyright collective (Q1047437) primarily for their mutual clearing activities (IIRC they represent each other on their respective "markets"): Creators (or the "industry"?) register individual works with their agency which in turn assigns an internationally harmonized identifier. However the page ISWC for music users is still "under construction". The online database http://iswcnet.cisac.org/ links creators (composers, arrangers, sometimes performers) via their IDs (which not yet seem to be ISNIs) with works and tendentionally also with recordings (specified by ISRC). Search for "Bach" and "Goldberg" yields about 100 works (mostly arrangements, many for individual variations only) but no ISWC for the original composition. My impression is that ISWCs (much more than ISNI and ISRC) are so execlusively utilized by the IP sector that kind of "general use" as in Wikidata will not be fun. -- Gymel (talk) 07:39, 7 March 2014 (UTC)

International number. This code is also burnt into music CDs. John Vandenberg (talk) 10:27, 6 March 2014 (UTC)

Clarification: It is roughly about "tracks" on CDs and the like:
In the case of Compact Discs the ISRCs and other PQ data are encoded in the disc subcode (Q channel) in the disc mastering process. For this reason, ISRCs must be encoded for each track in the Pre-Master for CD. The ISRC codes, together with the Digital Copy Prohibited flag (if appropriate), and the relevant point of sale code, such as EAN/U PC should be inserted on the Pre-Master during the pre-mastering process from the original master.

Do you mean the automatically generated link when clicking on the number or replacing this property with P973? The first is difficult since the url also includes the name (not only the number). The latter is less useful since it looses the underlying connection between the objects (i.e. the wikidata entity is same-as the given person-id link). It's essentially the same as replacing e.g. IMDb ID (P345) by described at URL (P973) /André Costa (WMSE) (talk) 12:37, 9 March 2014 (UTC)

Pictogram voting comment.svg CommentThus intended usage of the property is not always direct identification in the sense of authority control but rather a kind of categorization as in "This WD item (for a graphic novel, a trekkie convention, a motion picture, ...) belongs to (is somehow related to) the Star Trek universe"? -- Gymel (talk) 07:18, 25 March 2014 (UTC)
It includes specific magazines, such as the example Weird Tales, as well as Amazing Stories, Astounding Stories, and so forth. It also covers fictional universes, like the Star Trek Universe and the Cthulhu Mythos. In these cases, it acts more as subject-based authority control (rather than author-based or work-based). That isn't as common but there are some databases that cover subjects as well as authors and works. In practice, for example, the Star Trek Universe control would be appropriate for Star Trek (Q1092) (the data item for the franchise rather than the series), which already has a VIAF identifier. - AdamBMorgan (talk) 12:29, 25 March 2014 (UTC)
Oh, I see: WD already has items which could be provided with that property. And Star Trek (Q1092) shows that with GND ID (P227) at least one other authority control system already is hooked in. -- Gymel (talk) 16:39, 25 March 2014 (UTC)

Pictogram voting comment.svg Comment 'apple_(5781)' is a complex identifier. Who issues '5781'? A human or software? Is 5781 always 'apple_(5781)'? If so, can we link to just '5781', and let OmegaWiki redirect it to the relevant page? John Vandenberg (talk) 01:35, 7 April 2014 (UTC)
I did a inquiry. [2] --Bigbossfarin (talk) 17:26, 7 April 2014 (UTC)
Answers:
  • The apple part is optional, ignored by Omegawiki, unrelated to the defined meaning, and can be virtually anything.
  • The '(5781)' part is required, used by Omegawiki software, and idenfies a DefinedMeaning.
  • The number is assigned programatically. It may be altered only unter extremely rare conditions, such as (manual) error corrections.
  • Note that an underscore must precede the opening bracket in the URL.

Great, I have changed the 'allowed values' and example to numbers only, and the property URL voodoo will automatically add the '_(' and ')' before and after the number respectively. As noted on the OmegaWiki International Beer Parlour, http://www.omegawiki.org/DefinedMeaning:(5781) also works (but maybe it fails in some cases?, and there is code pending to allow http://www.omegawiki.org/DefinedMeaning:5781 to also work.

The definitive list of languages used by the Australian Bureau of Statistics (Q123347), with many Australian national standards built on top of it, and many applications & even processes/forms that include Joe-Citizen use it. Most language based data reported to the Australian government must reference this code. e.g. Excellence in Research for Australia (Q5419428) uses it to describe the language of a research publication. But perhaps a better example of its relevance is that Schools Interoperability Framework (Q1941131) uses it in the Australian implementation of the framework.[3] John Vandenberg (talk) 10:02, 6 April 2014 (UTC)
