Proposed byPathoschild

This property would contain the language scope defined in the ISO 639-3 standard; see Scope of denotation for language identifiers for a full description. This property is of general interest — the standard is widely recognized (including by the Wikimedia Foundation for its language codes), and the scope is used by the Wikimedia language committee to determine the eligibility for new wikis. —Pathoschild 20:56, 16 August 2014 (UTC)

It's not a duplicate of those. English has ISO 639-1 code "en", ISO 639-2/3 "eng" and is an individual language. Norwegian has ISO 639-1 code "no", ISO 639-2/3 "nor" and is a macrolanguage. - Nikki (talk) 13:24, 26 June 2015 (UTC)
ISO 639-3 only includes three scopes, "individual", "macrolanguage" and "special" (see [1]), it doesn't include "dialect" or "language collection" like this proposal suggests. - Nikki (talk) 13:24, 26 June 2015 (UTC)

        • Not really, depending on the country, primaries might just be an internal thing of some organization. We might not even now if they are held or not. Their main function is to designate an official candidate of an organization. If people are candidates to the actual election or not can be independent of that.

A political party can "protect" their ballots from such behaviour, but normally they don't. It was some noise about that in the last municipal election. A socialist in this way hijacked a seat that belonged to the nationalist party in a municipality.

ExampleGallaudet University (Q1056373) → 1864
Sourceexternal references, Wikipedia list articles, Wikipedia articles

On English Wikipedia, "Infobox university" frequently contains multiple founding dates for university. Some universities started out as polytechnics or as non-degree-granting (or as colleges where one could study for degrees issued by other universities). In Britain, when a university has the power to grant its own degrees, is is referred to as having attained "university status", and that is marked on a number of Wikipedia article pages in the infobox. See, for instance, the English Wikipedia articles for De Montfort University (Q3551402) and Buckinghamshire New University (Q448403).

The idea is we could then the "inception" property for marking when the organisation started, and this property to mark when it formally became a degree-granting higher education institution. —Tom Morris (talk) 11:56, 15 April 2016 (UTC)

I can't find any correct way of representing this currently - the best I managed was start point (P1427) which is clearly an incorrect usage. The origin of the material used is sometimes significant, in the example above it's significant as local stone, in archaeological contexts it's often significant as something that has travelled a long way.

I'm pretty sure we have a property lying around somewhere that can do this. "produces" is pretty close (if in fact the original creation rationale wasn't exactly this) and I'm pretty sure the inverse is currently being proposed. --Izno (talk) 16:29, 8 February 2016 (UTC)
With produces you could, for quarried/mined/manufactured material, say but the list of users would be immensely long in some cases and it is not in this context normally a significant aspect of the producing entity. It would also not be possible to use that for other materials, e.g. is fairly nonsensical,
⟨ Coastline of the North Sea (Q5138396)      ⟩ product or material produced (P1056)   ⟨ amber (Q25381)      ⟩
used by (P1535)   ⟨ Temple of Apollo, Delphi ⟩
very much is nonsensical (see w:Amber Road for how many places would need to be listed). Thryduulf (talk: local | en.wp | en.wikt) 01:25, 9 February 2016 (UTC)

⟨ 2015 Grand Prix de Fourmies (Q20872499)      ⟩ time search ⟨  17039 second (Q11574) ⟩

I work about cycling as you know. This morning, I discover thanks to @Edoderoo: the brand new property length (P2043) and I already use this property, like in Grand Prix de Fourmies 2015. One problem is solve. For the average speed, is ask to @Sjoerddebruin:, he gives me a link, and there is a property for speed that will exist. So to have an infobox that entirely works with Wikidata, it lacks me a property to write the time of a race. I find this data on the databases like ProCyclingStats.

The time will be written on Wikidata when we realise the classifications. We have general classification of the 2015 Coupe Sels (Q20895314) as example. It lacks the time for the winner, and the gap (écart in French) for all the other cyclists. The type of data is the same, we just are interested by the gap between these cyclists and the winner. For team time trial, we use the time, and the delay (retard in French) like here. Time is expressed in hours, minutes and seconds. It is also possible we use the centièmes de secondes but it is rare.

I need your thoughts about these properties, time and gap. Another will can be bonifications sometimes used in stage races. Jérémy-Günther-Heinz Jähnick (talk) 14:30, 10 September 2015 (UTC)

PS : to be more precise, I want the possibility to write 3 h 56 min 30 s (for example) on a same line, like dates. It must be fast to complete, and very easy. Jérémy-Günther-Heinz Jähnick (talk) 10:09, 11 September 2015 (UTC)

  •   Support This will enhance the cycling project. Also thanks for the length (P2043), a good step ahead I believe! Edoderoo (talk) 15:03, 10 September 2015 (UTC)

  • Comment. Is this supposed to work with any length of time? Please consider the name carefully. Note that we already have a badly named duration (P2047) that is intended to apply only to the length of recorded works, like films and albums. Is this proposal intended solely for the "winning time" in races? - dcljr (talk) 22:32, 24 September 2015 (UTC) — [Nevermind about "duration": I've renamed it to the more appropriate "running time". Forgot that property names are easily changed. :) - dcljr (talk) 18:11, 25 September 2015 (UTC)]
    • Comment. I think what might work would be something like participant (P710) with qualifiers of "finishing position" <number>/"classification" <string> and "finishing time"
  •   Comment use duration (P2047) --Pasleim (talk) 12:15, 1 October 2015 (UTC)
    • duration (P2047) is only for the length of recorded works. - dcljr (talk) 18:45, 1 October 2015 (UTC)
    • Comment To respond, if you read, I need three properties for time : time, gap and bonification. These properties will be always use as qualifiers, except the time for a cycling race, we already have the place in the fr:Module:Infobox/Descriptif course cycliste. There is particular cases on classifications like time trial where it is a little different that a general classification. Finally, I will repeat that I absolutely want to have the possibility to write a date in hours, minutes and seconds on a same line. It is very important because it needs to be very easy to be adopted by other users. Jérémy-Günther-Heinz Jähnick (talk) 15:37, 6 October 2015 (UTC)
      • Jérémy-Günther-Heinz Jähnick: Can we rename this as "race time" so it is clear it is for races and not for other things?
        • @Jérémy-Günther-Heinz Jähnick: I would actually recommend something like "elapsed time" since it should be able to be used for other things. However it needs to be differentiated from most of the 'time' properties which are really for identifying 'point in time' (which at the moment means dates, not really times). This property should be able to be used for any event with a recorded elapsed time. Josh Baumgartner (talk) 16:34, 23 October 2015 (UTC)
          • @Joshbaumgartner: it is as you want. My level in English is not very good, so if I can understand when somebody speaks to me or write to me, it is a little complicated for me to respond by speaking or by writing. Jérémy-Günther-Heinz Jähnick (talk) 16:46, 23 October 2015 (UTC)
Note that you will not be able to enter times in Hours/minutes/seconds as the "quantity with units" datatype only takes decimal numbers at the moment. Ask at Wikidata:Contact the development team for info about when this might be fixed.
Instead of the "gap" times can we just give the "race time" for each rider so one property does both jobs?
No idea what 'bonification' is but it sounds very rude in English. Joe Filceolaire (talk) 23:38, 6 October 2015 (UTC)
I really need three properties, bonifications is a time of 10, 5 and 3 seconds winning on the general classification for the three first of a stage for the general classification. I don't have the word in english but is is maybe the same. In this case for example, we need to have a property for the time and another for the gap/delay. So, in total, it is three properties. It is not a problem if I must wait few monthes. I let a message on Wikidata:Contact the development team. Jérémy-Günther-Heinz Jähnick (talk) 08:30, 7 October 2015 (UTC)
@Filceolaire: "Bonifications" means time bonuses. --Casper Tinan (talk) 11:56, 7 October 2015 (UTC)
Thanks Casper. So 'Bonification' is similar to the 'time penalties' added to competitors times in some sports except it's a time reduction. That property could be useful for a number of sports. Joe Filceolaire (talk) 21:29, 7 October 2015 (UTC)
  •   Support as "elapsed time". As noted, times will have to be entered in seconds, minutes, hours, etc., not in a combination. The numbers might seem odd but they will work (just require some client processing to make human readable). I would also support sub-properties such as gap time, penalty time, and bonus time. If negative numbers are acceptable, maybe penalty time and bonus time can be combined? I filled in som of the template as well. Josh Baumgartner (talk) 16:34, 23 October 2015 (UTC)

@Yair rand: Fair enough. What about something like label: 'elapsed time', description: 'measured time elapsed over the course of an event'? Are there specific concerns behind wanting to keep the property more specific? Josh Baumgartner (talk) 22:21, 17 November 2015 (UTC)
@Joshbaumgartner: Would this be used for any event? For example, would it have a value of a number of days for long events like olympics, elections, wars, etc? If so, that would be redundant with start/end date data. I think this needs a more restrictive scope than that. --Yair rand (talk) 01:21, 23 December 2015 (UTC)

Using a generic property would follow the same logic as significant event (P793): it is easy to adapt to the specific product that we want (say light crude oil (Q1047462) instead of just "oil"), and in case a specific property is created afterwards, data can still be transferred. --Zolo (talk) 08:48, 17 December 2015 (UTC)

This is effectively a unique ID for a older vessels. Danrok (talk) 13:54, 24 November 2015 (UTC)

  Question @Danrok: Are you withdrawing this proposal, or do you still see it as useful? Josh Baumgartner (talk) 19:35, 7 January 2016 (UTC)
@Joshbaumgartner: Not withdrawing it. As far as I can see, it is very useful because it is a unique ID. Radio call-sign and code letters are basically the same thing and should share this property. Danrok (talk) 14:25, 8 January 2016 (UTC)
  Support as proposed. Thanks for the clarification, Danrok. Would it make sense to add a filter to this property? Josh Baumgartner (talk) 17:05, 8 January 2016 (UTC)
  Question @Danrok: How certain are we that older vessels carry unique codes? Is there something like a partial source you can show as an example? Lymantria (talk) 20:47, 27 April 2016 (UTC)
@Lymantria: "no two ships bore the same code letters at the same time" quoted from the Wikipedia article. Either way, this property is definitely needed, it is the predecessor to IMO ship number (P458). The subject item in the proposal should be international maritime signal flag (Q1671640), instead of international maritime signal flag (Q1671640). Danrok (talk) 21:33, 27 April 2016 (UTC)
@Danrok: I suppose you mean code letters (Q5140072) for the subject? I understand from [:en:Call sign]] that when it comes to combination with call signs, the ship code may contain numerals as well. Would [0-9A-Z]+ make sense as regex for allowed values? Lymantria (talk) 06:45, 28 April 2016 (UTC)
@Lymantria: Yes, it is a string of alpha-numeric characters. Spaces and lower-case a-z should also be allowed. For example, Mercury-Redstone 3 (Q623903)'s radio call sign was "Freedom 7". Danrok (talk) 12:48, 28 April 2016 (UTC)
So, I think it may be best to use this existing property call sign (P2317) to cover all call signs, including the older "non-radio" maritime code letters. Danrok (talk) 13:00, 28 April 2016 (UTC)
I agree, but then descriptions of call sign (P2317) have to be adjusted. I can consider this request withdrawn? Lymantria (talk) 13:57, 28 April 2016 (UTC) (forgot to @Danrok:)
As said above, this property can double-up as call sign (Q353659). Danrok (talk) 21:50, 27 April 2016 (UTC)

  Not done I consider this request withdrawn, in favour of use of call sign (P2317) for this matter. Lymantria (talk) 07:43, 5 May 2016 (UTC)

Sourceexternal reference, Wikipedia list article, etc.

The number of an individual vehicle is often a noted fact, especially for rail locomotives. There are two use cases for this I can think of, the first is on items about individual vehicles and the second is on items about notable events (e.g. accidents) where that vehicle is significantly involved (where it would be used as a qualifier to item operated (P121). aircraft registration (P426) exists for aircraft and is used in a broadly similar way, and IMO ship number (P458) exists for ships but I'm don't that merging or generalising those would be a good idea - indeed it might be better split this proposal into separate properties for rail vehicles and road vehicles? Thryduulf (talk: local | en.wp | en.wikt) 15:28, 17 November 2015 (UTC)

@Snipre: That would prevent validation of values. Code letters are always letters as far as I know. Plus, there's also another one for ships called Official Numbers [3], a system which came after code letters, and before IMO ship numbers. These unique IDs are very important because they allow for the finding of a ship on say the Lloyd's Register, and other official paperwork, archives, etc. I need to read-up more on official numbers before making a proposal on that. Danrok (talk) 13:56, 26 November 2015 (UTC)

      • But the property doesn't exist! The constraints for inventory number (P217) are not wrong, they exist to enable validation of the accession numbers for items in a GLAM collection and are correct for that job. That is a completely different concept to fleet numbers and registration numbers of vehicles (which may or may not be part of a collection, and when they are will likely have an accession number as well as a fleet and/or registration number). Thryduulf (talk: local | en.wp | en.wikt) 20:11, 8 March 2016 (UTC)
      • @pigsonthewing: as my above comment doesn't seem to have been spotted. Thryduulf (talk: local | en.wp | en.wikt) 12:44, 11 March 2016 (UTC)
  • @Thryduulf, pigsonthewing: In no way is a vehicle's registration number the same as a museum's inventory number. That is definitely not how this should be done. Boats and planes are held in collections, so clearly the two would become muddled up. Danrok (talk) 21:24, 11 March 2016 (UTC)
    • Which is why I wrote "No prejudice against a separate property, if that is not deemed appropriate, for registration numbers". inventory number (P217) is qualified by the name of the collection to which the inventory number refers; and thus multiple values may be stored. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:57, 11 March 2016 (UTC)
      • @pigsonthewing, Danrok: a fleet number is not conceptually different to a registration number (it's a unique identifier for a vehicle), but both are very different to accession numbers and there is no collection name with which you can qualify a fleet number if the vehicle is not in a collection. Thryduulf (talk: local | en.wp | en.wikt) 17:20, 14 March 2016 (UTC)
        • You're being Anglo-centric. In some countries, the registration number changes with the registered owner, or yearly. However, this is not the place to debate such matters. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:45, 14 March 2016 (UTC)
          • eh? Accession numbers are stable and don't change yearly, whereas fleet and registration numbers can - this is another argument against inventory number (P217)'s suitability. Thryduulf (talk: local | en.wp | en.wikt) 12:36, 16 March 2016 (UTC)
            • Accession numbers can and do change; we have start- and end- date properties for use as qualifiers in such cases. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:48, 16 March 2016 (UTC)
  • I think that it is important that inventory number (P217) is only used for a collection's inventory reference, and nothing else. It's an ID which unambiguously pinpoints an item in a collection which could be very large, and contain very similar items. If we start storing any "other marks" in inventory number (P217) that just creates work for anyone using the data, they will have to code some method of separating values stored in inventory number (P217). It also increases the possibility of mistakes and mix-ups. That's just making things more complicated than they need to be, with no benefit that I can see. Danrok (talk) 18:32, 14 March 2016 (UTC)
    • I agree entirely. The fleet number of a vehicle is "a collection's inventory reference" and it does "unambiguously pinpoint an item in a collection which could be very large, and contain very similar items". That is precisely what it is for. We already have "method of separating values stored in 217": qualify them with the name of the collection or issuing body; and dates if relevant. However, this is not the place to debate such matters. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:45, 14 March 2016 (UTC)
      • It is clear from the description, constraints and proposal for inventory number (P217) that it is only intended to be used for GLAM collections. A vehicle in a museum may have one of these, an operational vehicle does not as it is not in a GLAM collection (or in most cases in any collection at all). A registration number issued by, e.g. the DVLA is a conceptually very, very different thing in both form and purpose to an accession number issued by e.g. the National Motor Museum. Vehicles may have multiple concurrent fleet and registration numbers, but only one accession or inventory number is current at any one time. Thryduulf (talk: local | en.wp | en.wikt) 12:36, 16 March 2016 (UTC)
        • You are, sadly and inexplicably, making things up. There is nothing in the description which mentions, let alone limits this to, GLAMs. Anything with fleet number is part of a collection; that is what the "fleet" is. As I said early on, constraints which are wrong can be - and should be - changed. A registration number issued by the DVLA is a conceptually very, very different thing in both form and purpose to a fleet number; which is why, I repeat, I wrote "No prejudice against a separate property, if that is not deemed appropriate, for registration numbers". And once again, this is not the place to debate such matters; and the use of P217 is now being discussed on Project chat. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:03, 16 March 2016 (UTC)
  •   Support Useful property. To me, inventory number (P217) is conceptually something completely different. --Srittau (talk) 14:18, 16 March 2016 (UTC)
  •   Support (though I would simplify the label to "fleet number" and clarify that it should be owner/operator-based, not an external registration number.) It seems to me Andy's claim rests upon an assumption about the meaning of the word "collection". What does "collection" in the context of inventory number (P217) signify? Well, it's clear from the discussion page and usage that it refers specifically to the property collection (P195), which has corresponding item public collection (Q2982955), described as a collection of "works", and a subclass of art collection (Q7328910). The set of locomotives owned or operated by a particular railroad, while technically a "collection" in the sense of something that contains multiple items, does not to me by any stretch qualify as either a public collection (Q2982955) or art collection (Q7328910). I also am quite concerned that Andy acted to close the discussion rather than simply add an "oppose" comment. If there is a significant concern about the creation of duplicate properties let's maybe start an RFC with concrete proposals for how to deal with it. I don't think this qualifies as a duplicate in any case. ArthurPSmith (talk) 17:57, 17 March 2016 (UTC)

  •   Comment The linked discussion on Project chat (now archived at Wikidata:Project chat/Archive/2016/03#P217 - should it be broadened?) was not explicitly closed, but does not seem to my (biased) eyes as concluding in favour of broadening inventory number (P217). Accordingly I think the objections to this proposal with that reasoning can be dismissed when judging whether this property has gained consensus or not (currently I'm seeing a likely consensus for either combined or separate properties, but no consensus between the two options).

    • There is no consensus for your proposal, in either form (there may be for a "registration number" property, as I have already indicated) - since, as I demonstrate irrefutably above, it is flawed and unnecessary for a fleet number (which is equally irrefutably an "identifier for a physical object... in a collection"), with P217 being perfectly adequate for that purpose, and the objections to using that being based on a false premise otherwise.

DescriptionThe measure of the number of elements if the item represents a set and the number of elements is unknown or changing. Sets with fixed amounts should use cardinality of the group (P1164) instead.
Representscardinality (Q4049983)
Data typeItem
Allowed valuesall instances of cardinal numbers (which include natural numbers and also : n (many) (Q22952775), aleph ω (Q22952698), aleph one (Q2832673), aleph null (Q1445491), beth ω (Q22952652), beth two (Q22952656))
Examplephalanx of the foot (Q184494)n (many) (Q22952775)
Proposed byUser:Thewormsterror

I stumbled across phalanx of the foot (Q184494) that had the incorrect property of being an instance of bone. Switching this to subclass alone would be technically correct but incomplete. Having a cardinality would really help describe the concept. One could argue that in this particular case the item most likely should be renamed to Phalange of the foot (that's probably for another debate). However there are many other items where the cardinality would be handy like "Presidents of Egypt".

I found a similar property called cardinality of the group (P1164). I propose renaming that to cardinality (count) or just plainly count since it actually measures the count and doesn't deal well with sets where the count is unknown or changing. It might be brought up that another option is that we get rid of that but I think that property is handy for things where the count never changes like 'the 3 stooges' or 'the 7 dwarfs' (in snow white).

I would like to point out that very often the only cardinalities used here will be zero (Q204), 1 (Q199) and n (many) (Q22952775). By themselves zero (Q204), 1 (Q199) don't make much sense but they can used as qualifiers.

Since this is used so often in modeling it would allow us to for example to say things like a table has N legs if we reference this with the part of property. I hope people can understand what I'm getting at.

In line with the table example I also think we could have another property min cardinality, which would only allow natural numbers. 99% of the time it would be 0 or 1. But in the case of a table it would be 3. Matching that with cardinality n(many) would mean that a table has between 3 to N legs.

There are many many applications for this property and I'm surprised it doesn't exist yet since it's so common in UML, Merise and many other modeling diagrams.  – The preceding unsigned comment was added by Thewormsterror (talk • contribs).

@Thewormsterror: It exists, it's quantity (P1114)  . It's supposed to link a class (set) to its number of instances, originally. It may have evolved over time, as other properties in Wikidata. But this won't work for infinite set of classes however, so we need a property with item datatype. author  TomT0m / talk page 15:13, 22 March 2016 (UTC)
@TomT0m: Basically I want to compliment the quantity property with a cardinality property. This one would basically be used for 2 main things (there are other types of cardinalities for rare situations). The first of the 2 being for things that are changing but must be N. Like Birds of North America (Q2904442) or List of heads of state of Egypt (Q774262). We know they are plural but the amount often changes, hence the cardinality would be n (many) (Q22952775). But then we can also use qualifiers with properties such as part of. So you could say something like a planet is part of 0 (rogue planet) or 1 (normal planet) solar system. For this we would need 2 properties min cardinality and (max) cardinality. That is what I would prefer from this discussion. I really hope people can understand the difference from quantity here. Thewormsterror (talk) 17:00, 25 March 2016 (UTC)
@Thewormsterror: I don't think your examples are useful. Wikidata has already mechanisms for changing values : several statements qualified with their dates of validity. For unknown values there is the special value unknown value Help. So I don't get your point. author  TomT0m / talk page 17:12, 25 March 2016 (UTC)
@TomT0m: I'm sorry, I might not have explained well enough. I remember in my class in university not everyone understood the point of cardinality. Let me start by saying that the point of all properties on wikidata is to gather relevant information on entities and that's what I'm trying to do here. The information is not that there are 5 or 7 or 1000 elements (quantity) that are changing over time, if the cardinality is N the information is that there are a variable N amount of elements where N is set containing all natural numbers. I think why this is difficult to understand is that 99.9% of the time the cardinality will be n and will just mean that the thing can be plural. But there are a few entities that are bigger than N such as infinite set (Q205140) which has a cardinality of aleph null (Q1445491). And very often the cardinality will be fixed which I think is why you misunderstood. For example lets say that there have been 46 presidents so far, the quantity is 46, but the cardinality is N, since there can be more, if the cardinality was 46 that means that 46 is an absolute value. Furthermore I hope people can understand the cardinality is the set of allowed values and not the values themselves. So if the quantity is fixed at 5 and has always been 5, the cardinality would be the set with only one element 5, so for fixed quantity items it's easy to confuse the 2. Thewormsterror (talk) 05:30, 27 March 2016 (UTC)
@Thewormsterror: I think I understand your point but I don't see how the "n" cardinality would be useful. The quantity (P1114)   property datatype is number and the set of values defined by this datatype is definitely a subset of Q - mod the precision information, so say an interval in Q - so there is no possible infinite values (maybe unknown value Help fits however) - plus the infinite values. In the example of phalange of the human foot we can be way more precise using the precision notion - unlikely to have a human foot or a table with 1000000 feets. author  TomT0m / talk page
@TomT0m: I think I'm pretty bad with the examples I've given here. I understand why you would think N is not very useful by itself. If it's used as a property it really only describes things as being plural. When the cardinality is used as a qualifier for properties it can be very useful though. As qualifiers the 3 main cardinalities used would be 0, 1, and N. Adding in min cardinality (I really want this too) as another property would also be amazing at describing triples. Let's say I wanted to describe a solar system. A solar system may have up to N planets and a planet is part of 0 or 1 solar systems. You would therefore say a planet is part of a solar system with min cardinality 0 and (max) cardinality 1. And a solar system has part of planet with min cardinality 0 and (max) cardinality N. The min cardinality is important because it differentiates must have and may have but really only works as a qualifier. I hope I'm getting my point across. But in this example you see where max cardinality can be 1 since a planet can not be part of more than 1 solar system. Thewormsterror (talk) 11:26, 27 March 2016 (UTC)
@Thewormsterror: OK, I think I'm beginning to understand, you speaking of describing classes in a way similar to a class definition in UML for example.
For example for the solar system class you mean something like
Is that so ? I wonder then if it should be the same property as the one for mathematical sets. But yes, it could be useful and would probably help us to build a better constraint system. author  TomT0m / talk page 12:40, 27 March 2016 (UTC)
@TomT0m: You got it. The reason I thought the property might as well be the same, is because the concept of cardinality is either describing an entity or a relationship. As I see it, we could either have 2 properties: min cardinality and cardinality, or 3 properties : min cardinality, max cardinality and cardinality; with min and max being for qualifiers and cardinality being only for entities. Conceptually I think the first solution is better, however the second solution is easier to understand. Thewormsterror (talk) 02:09, 28 March 2016 (UTC)
  Support but just for the cardinality of mathematical sets at this point. Might need some thinking for number of values of properties - although we already have unique value constraint, and a value can either be unique, non unique (n) and cannot be infinite ... author  TomT0m / talk page 10:38, 27 March 2016 (UTC)
I'm still waiting for this to be added :) if possible Thewormsterror (talk) 19:05, 1 May 2016 (UTC)

@Thewormsterror, TomT0m:  Done Created this property with some hesitation. In accordance with TomT0m I added a constraint to restrict the domain to set (Q36161). I noted that group cardinality (P1164) is related, but is restricted to finite groups and has quantity datatype. I added a "conflicts with" constraint with this property and with quantity (P1114). The latter so that you may relax the domain when all turns out to work out as expected. Happy editing! Lymantria (talk) 16:56, 6 May 2016 (UTC)

            • Wikipedia lists 200+ major active social networks. Are you proposing to create properties for each? Will the research be skipped over? What can Wikidata take from these external-id? Most uses have been speculative.

              From my perspective, this proposal is easier to use, work with, reuse, verify, and more flexible than a splitting URLs into P553+P554. If we could write default JS to breakdown and reassemble URLs for P553/P554 then lets do that. But I'm skeptical that'll happen in the next decade. Dispenser (talk) 18:42, 9 April 2016 (UTC)

involved in event

   Not done
Descriptionpeople, vehicles, and other items involved in this event
Data typeItem
Domainoccurrence (Q1190554)

I was trying to describe which aircraft was involved in Flydubai Flight 981 (Q23253749). Currently there is no way to do this, except using item operated (P121) with a aircraft registration (P426) qualifier. But this seems like a misuse of item operated (P121), since this property is supposed to describe a class of vehicles used by an organization, not an individual vehicle involved in an event. Also, it does not allow to link to the item of an individual vehicle. In cases like this an item describing the vehicle involved would be quite advantageous, since it allows to capture a lot of information that is referenced in the article, like production date, ownership changes, images etc.

This property can also be used in other kinds of events, not only accidents and for other types of items, like airplanes, rail vehicles, road vehicles, ships, but also persons and other things involved in an event (that cannot be better described by a narrower property). This is the reason the property is as broad as it is and not something narrower like "vehicle involved in an event" or even "vehicle damaged in an accident". If necessary, such sub-properties could always be created later.

This is a super-property of organizer (P664) and participant (P710).

--Srittau (talk) 19:37, 21 March 2016 (UTC)

  •   Comment I've been musing on something like this due to my work with rail accident entries. I am unsure though why you say that item operated (P121) would not allow the use of an item for the individual aircraft? I was thinking of creating items for the individual train services involved in rail accidents (rather than overloading applies to part (P518)/has part (P527) as at e.g. Dagenham East rail crash (Q5208483)) and linking to that using item operated (P121). I'm not sure that that is the optimal solution, particularly as at Polmont rail accident (Q7225869) the train and the cow that hit are listed as separate types of property, however I'm not sure either that this is the optimal solution either. I'm leaning support but more thought is needed. Thryduulf (talk: local | en.wp | en.wikt) 20:30, 21 March 2016 (UTC)
    • Well, item operated (P121) is currently ill-defined, because its use was broadened in some languages, but not others. Nevertheless according to both the old and the new proposal on its talk page, it is supposed to link organizations to types of vehicles (classes) (or even more broadly defined stuff) used by that organization. I wouldn't like to overload that with individual vehicles (instances) involved in events (like accidents), which - to me - is something very different. --Srittau (talk) 21:07, 21 March 2016 (UTC)
  •   Oppose as proposed. The proposed name is vague and confusing, and reads as if its object should be the event rather than the vehicle. If the example is correct, the property should be called "vehicle involved". If the event is supposed to be the object, then the example needs to be reversed. Assuming the example is as intended, and no item exists for the individual vehicle, what's wrong with using aircraft registration (P426) as a property of the event itself, instead of as a qualifier of a statement for which there is no good existing property or object? Swpb (talk) 19:58, 30 March 2016 (UTC)
    • I am always open for better names and descriptions. But please note that this proposal is not just about vehicles, but a very general way to tie items to events. I have added another example. In the specific case of aviation accidents, it makes sense to create items for the vehicles involved. If you look at Wikipedia articles about those events, you will find detailed background information about the airframes involved, data that should be captured on Wikidata. We also have Commons categories for many individual airplanes, which could be linked to the specific vehicle involved. Similar data is available for other kinds of vehicles, for example rail vehicles. --Srittau (talk) 18:53, 31 March 2016 (UTC)
  •   Oppose - Per Srittau above, and because this information could be mined far more effectively by querying which items link to a particular event via significant event (P793). -- Netoholic (talk) 07:07, 23 April 2016 (UTC)

  •   Comment just noticing that we currently have not much besides publication date (P577) which AFAIK for most works in the visual arts by analogy is the date of first public display (e.g. in an art gallery). Objects like Two men contemplating the Moon (Q232087) use inception (P571) for their creation, could this be applied to films, too? There is also the aspect of manufacturing, e.g. for instances of e.g. bronze sculpture (Q928357) which are produced by casting (Q496098) the manufacturing or producing of some or all individual exemplars may be quite different from conception (AFAIK art historians frown upon the concept of a series of sketches and early stages somehow culminating in the artwork which becomes known) or creation (understood narrowly as the time when the artist made the cast). But for films I'd understand this as being the date when individual copies are created from the master. -- Gymel (talk) 06:16, 12 April 2016 (UTC)

Filmiroda rating


As it happens Hungary has been using its third motion picture rating over the last half a century. Each of them used a different set of categories and were issued by a different body. The latest one has already a property as NMHH film rating (P2363). This property would cover the second of the three. Many of these ratings are still in active use today, and a few times NMHH has also referred back to the Filmiroda ratings instead of re-rating. Thousands of values can be expected (numbering on certificates went up to 11770 but that includes non-notable releases as well). – Máté (talk) 21:27, 9 April 2016 (UTC)
