This page is for the proposal of new properties.

Before proposing a property

  1. Check if the property already exists by looking at Wikidata:List of properties (research on manual list) and Special:ListProperties.
  2. Check if the property was previously proposed or is on the pending list.
  3. Check if you can give a similar label and definition as an existing Wikipedia infobox parameter, or if it can be matched to an infobox, to or from which data can be transferred automatically.
  4. Select the right datatype for the property.
  5. Start writing the documentation based on the preload form below and add it in the appropriate section.

Creating the property

  1. Once consensus is reached, change status=ready on the template, to attract the attention of a property creator.
  2. Creation can be done 1 week after the proposal, by a property creator or an administrator.
  3. See steps when creating properties.

On this page, old discussions are archived. An overview of all archives can be found at this page's archive index. The current archive is located at 2020/07.

A very comprehensive and detailed database that described the use of firearms in works of fiction.

I might be wrong but this might be our first property related to firearms. Once we are done, we can make properties for actors, firearms and manufactors as well.

Another thing to note, animated televisions shows (that doesn't include anime) are usually banned unless the firearms are clearly identifiable.

I'm not sure whether or not placeholder articles should be included. --Trade (talk) 20:50, 27 June 2019 (UTC)

Usually we prefer properties in the direction that connects many items to one, rather than one item to many. Jheald (talk) 17:39, 8 July 2019 (UTC)

--Oursana (talk) 02:28, 15 July 2019 (UTC)

  • Pictogram voting comment.svg Comment I agree with Jheald here - the direction of this property feels wrong to me. Is there not a risk that a given item could have a lot of statements for this property? Marking as not ready. − Pintoch (talk) 21:09, 23 July 2019 (UTC)
    • one item to many?? I do not understand the arguments of Jheald and Pintoch. Could you please give an example and explain. There are very few Werkverzeichnis, normally none to one, maximum very seldom 3--Oursana (talk) 10:37, 24 July 2019 (UTC)
      • By one item to many we mean that it would be more natural to add a statement in the other direction, from each "catalogue raisonné" to its subject. The many in this phrase does not mean that there would be too many links to do it in the other direction, it is just a description of the relation (see en:One-to-many (data model) ). − Pintoch (talk) 10:49, 24 July 2019 (UTC)
        • I'm neutral on this one. I'm quite reluctant about creating one to many properties, in this case one person with multiple catalogue raisonnées, but what would be the maximum here? What artist has more than 10 of them? Maybe Rembrandt (Q5598)? @Jane023: as our catalog queen, what do you think? Multichill (talk) 09:40, 27 July 2019 (UTC)
          • Thanks for the ping. Though I am all for more catalogs raisonné on Wikidata for artists, the catalogue raisonné (Q1050259) is currently also in use for all sorts of things, not just "all works by artists", but also "all items in collection". That said, yes it would be nice to have a link from the artist to an item about their most notable (or only!) monograph. But the problem here is exactly the same as the one for the "Notable print" proposal for paintings that I had before. Who is to say that the notable print is indeed notable? Is it notable because it made the painting famous? Or is it notable because it was copied by a notable painter? Or was it made when the painting was in an important collection? Though valid, those questions don't even come near the crux of the matter which is that the print (or catalog in this case) has a specific instance as an edition. Do we want all editions and/or translations? I think not. The way to handle the problem this proposal tries to address is to try and address the issue of having a "reasonator-like link" on the artist page that will point the reader to all Wikidata resources available, such as the creator lists of course, but also (and not limited to) the catalog raisonné listeria list (if it exists).

  • Jean-Fred (talk) 16:30, 30 September 2019 (UTC)
  • I'm also skeptical about this property. IMO characters (P674) would be enough in this case. Sir Lothar (talk) 13:49, 3 October 2019 (UTC)
    • That means one would need to know all characters, enter all characters, be sure that a given Wikidata item includes all characters. Not sure how one could do the last one and if it's efficient to do the first two in advance. --- Jura 15:43, 4 October 2019 (UTC)
      Hmmm, looking deeping, I guess there is some precedent for that, with things like number of children (P1971), number of episodes (P1113), number of seasons (P2437) (although, for the last two, the count is inferred via inverse properties) ; or the combo number of parts of this work (P2635)/tracklist (P658).
      I find the argument “how can we be sure that characters (P674) is complete” a bit curious to be honest − it could apply for a lot of properties − “number of actors” for cast member (P161), “number of editions” for has edition or translation (P747), “number of parts” for has part (P527), etc. − no?
      Also, is this supposed to be qualified to make the difference between, starter characters, unlockable characters and downloadable characters? How about palette swaps?
      Jean-Fred (talk) 17:04, 4 October 2019 (UTC)
      “one would need to know all characters” → Are there cases where one would know the number but not have the list? Jean-Fred (talk) 17:05, 4 October 2019 (UTC)
      Having a list isn't enough, we also need someone to add all of them to Wikidata in a structured way. Which is a ton of work and IMO way more work than the few people currently active in that area on Wikidata are able to handle. --Kam Solusar (talk) 15:24, 5 February 2020 (UTC)
      • I'm not sure about the need for this property as I don't edit these items, but I tried to spell out what would the underlying assumptions of the "use P674" argument. I don't think it's comparable with "number of editions" as that is not a static number. --- Jura 11:39, 5 October 2019 (UTC)
        • Well, from a gamer's point of view, i just don't see how this property could be useful, that's why I wrote I'm skeptical. It's much more informative to write for example, that one can choose Raiden, Sub-Zero or Scorpion in Mortal Kombat (Q150294), than to say it has max. number of 7 playable characters.

      @Trade: Any character that doesn't have its own item can have one created. That's how such properties work. --Yair rand (talk) 20:08, 12 January 2020 (UTC)
      Can have its own item. Unfortunately, in practice, that's not the case, not even remotely. Creating items for all characters takes time and effort, even more so if we expect those tens of thousands of character items to contain more than just a label and description in one or two languages plus a instance of (P31) statement. I've worked quite a bit in this area here on Wikidata and AFAICS we only have very few game items that have a complete list of all characters (playable or otherwise). There simply aren't enough active users here compared to decdicated gaming databases, and not enough users willing to invest all that time and work to create, expand and source thousands of such items manually. Plus users of our data have no way of knowing whether a game item has a complete list of characters or if some/most are still missing. Which would make numbers of characters derived by counting the listed characters inherently unreliable. At least for the forseeable future. --Kam Solusar (talk) 15:24, 5 February 2020 (UTC)
  • Symbol support vote.svg Support Yes, in theory the number could be derived from the characters listed on the game's item. But we're very, very far from having items for each and every character and no way of marking a character list as complete. At the current state of things I really can't see us getting to the point where it would be a reliable method, at least within the next decade or so. But a simple "number of characters" statement as proposed would be way less work to implement and would be reliable and of use for users of our data instantly, instead of potentially being somewhat reliable many years down the road. --Kam Solusar (talk)

What we should be doing today is setting up the foundations for that to be possible. I'm still too new to Wikidata to say with confidence whether Tinker Bell's approach is the best one, but from what I can tell, it makes sense to me.

Create a relationship to indicate when items are featured in a creative work. Featured items could be either animate or inanimate. This would allow Wikidata to reflect the instances when items are depicted in popular culture. present in work (P1441) comes close to serving this purpose, but that property was created to identify when a fictional entity (Q14897293) or historical person is present within a creative work.

    As this was brought up by others: I oppose the use of present in work (P1441) for the examples mentioned by you. present in work (P1441) is used to indicate entities that appear as part of the story of a fictional work, not as part of the soundtrack, cast or film set; e.g. there is a difference if Marlene Dietrich (Q4612) "appears" in a film as a character or as an actress and I think it is useful to be able to distinguish between those cases. - Valentina.Anitnelav (talk) 08:50, 5 November 2019 (UTC)

Adding those 100 statements to the item for Lincoln would be problematic as it makes that item take long to load.

I think this is interesting cultural data to capture, for instance, it provides data on things like which fashion brand is name-dropped the most in rap. However, there is also application to literary works - with the distinction from present in work (P1441) being that these entities are not actually present in the events of a work, only mentioned by name. See discussion at project chat here: Wikidata:Project_chat/Archive/2019/11#How_can_we_state_that_a_person/entity_was_named_in_a_creative_work

The difference from other proposals such as Wikidata:Property_proposal/mentioned_in_work and Wikidata:Property_proposal/Mentioned_at is the better defined scope/application of this property not currently covered by existing related properties (and also this property is a statement on the work item, since an entity could be mentioned in thousands of works - leading to excessive statements on the entity item). --SilentSpike (talk) 16:44, 8 November 2019 (UTC)

  • Pictogram voting comment.svg Comment Responding to some of Jura's questions (from project chat) here for archival purposes:
What type of work would this apply to? How many such statements should we have? Most works have a person or place index should these all be included?
  1. I think this can apply to any sort of work that has written or spoken content. My main motivation is the application to lyrical works as that's where I see the most value in how this represents cultural influence and reach (i.e. if many songs name the same entity, then it is shown to be culturally significant). However, the same line of thinking can be extended to written works (see example 4 of the proposal) where the existing property for something's presence in the work doesn't quite cover the case of an entity only mentioned by name.
  2. As many as are valid statements? I don't see an abundance of statements existing for most works since the use case and allowed values of this property limit what it applies to (i.e. persons/locations actually present in the work are already captured via other properties and this is also only applicable entities with names - aka "grass" does not mean there should be a statement for grass (Q643352)). As for works that are very referential, that seems to me like a valid use case where there may exist many values and the use of this property helps to establish that the work is heavily referential in a machine readable way.
  3. Good question, I'm not sure to be honest. My gut reaction is no since those seem like metadata about the work rather than actually being part of the work. However, perhaps they should with a qualifier to indicate that they're part of the index (also keep in mind, persons/places that are present in the work are already captured by other properties and don't belong in this property about entities only named).

    • I don't believe so since there's a distinctly different set of allowed values. That property would cover works paying tribute to other works by borrowing ideas, concepts or events specific to them (which cannot really apply to any given entity). Whereas this property can apply to any given entity explicitly named (only) in a work. I feel like that's not the best explination possible, perhaps Valentina.Anitnelav can shed some light on the difference more succinctly. --SilentSpike (talk) 19:55, 11 November 2019 (UTC)
    • Currently they are not exactly equivalent (as explained by SilentSpike) and I admit that I'm also a bit partial to having a distinct property for references between works. On the other hand it might be actually possible to subsume this ("mentions") proposal under Wikidata:Property proposal/references by broadening the latter's scope to include all kinds of entities. If such a property should be accepted (in spite of concerns that it might be too broad) one should probably follow Jmabels proposal to indicate the kind of reference via a qualifier, maybe a new one along the lines of <kind of reference> that may take values like "mention", "allusion", "parody", "copy of style", etc. - Valentina.Anitnelav (talk) 20:08, 11 November 2019 (UTC)

This is about adding a property to indicate which publishers make their work available online at no cost. The main motivation I see is to keep track of en:Open access scientific venues (journals and conferences) but the notion would make sense more broadly, e.g., for online newspapers (some require a subscription and some do not), online TV channels, etc.

We already have access status (P6954) but this is explicitly intended as a qualifier to indicate whether the DOI for a *single entity* (e.g., a single article) is open-access or not. So I think this is complementary to the proposal: it's better to indicate the access status of individual articles with access status (P6954) when they have a Wikidata entity, but for all the research articles, news articles, etc., that don't, then the availability status could be inferred from the status of the publisher.

There may be some corner cases in the definition, e.g., some scientific publishers distribute some works as open-access if the authors pay an extra charge; so I think the proposal should indicate the default status of articles (i.e., requiring no extra payment), possibly in a certain date range.

Another possibility is to use access status (P6954) as a qualifier of ISSN (P236) but this would not work for media without an ISSN. --A3nm (talk) 15:50, 14 December 2019 (UTC)


Thanks @ArthurPSmith: @Jheald: @Swpb: for the feedback!

Motivation[edit] is a fan-curated fairly complete database of things related to Star Trek (Q1092). Unfortunately they don't seem to have a URI system or canonical link element (Q1033568). This has the disadvantage that its not an id in that there is no single canonical string that represents an article. For instance these two ids:

Help:Add main subject with Mix-n-Match explains the steps of using Mix'n'Match (MxM) to identify items that are values for main subject (P921).

Initially, I used Sandbox-External identifier (P2536). That works mostly, but could use a few improvements. To avoid problems with other experiments, this proposal for a temporary property. Also, a dedicated property would make it easier to include custom code in MxM.

Note it's temporary in the sense that items for a given catalogue only use it for some time, but it's a permanent property as it can be used by other catalogues later. (Add your motivation for this property here.) --- Jura 20:35, 1 April 2020 (UTC)

I'd put those titles and their QID's into a csv file, load it into OpenRefine, tweak the titles to pull out likely label matches, then do OpenRefine's reconcile process to match those labels to Wikidata items, then dump out those title QID and matched QID pairs and load into Quickstatements to add the main subject (P921) statements. Or there might be a way to do it directly in OpenRefine. ArthurPSmith (talk) 17:55, 3 April 2020 (UTC)
        • I haven't tried OpenRefine's matching recently, but essentially, I would have to do all of them myself ;) Also, I couldn't see what's matching in other MxM catalogues. --- Jura 18:12, 3 April 2020 (UTC)

    • @Dhx1: It's an option I considered. An aspect is that the values wouldn't be meaningful by themselves and one would have to retrieve the (unconvertible) units to actually get the information. --- Jura 12:51, 5 May 2020 (UTC)
    • @Dhx1: another aspect is that on the Wikidata GUI, there is just no link to the unit and its item. --- Jura 14:40, 12 May 2020 (UTC)
    • @Dhx1: shall we move ahead with this? --- Jura 16:44, 17 May 2020 (UTC)
    • @Jura1: What about a quantity datatype (no units?) and determination method (P459) as a mandatory qualifier? Otherwise I think it'd be best to have a property created for each type of readability scoring method if the intent is to use the data directly in infoboxes. Dhx1 (talk) 23:15, 17 May 2020 (UTC)
      • @Jura1: Cancel my previous suggestion, as determination method (P459) would probably describe the process used to generate the readability score. For example, a particular software product and version was used, or a score can be generated in two or more ways. Besides creating multiple properties for each readability score method, use of units still seems to be most appropriate despite the limitations you mentioned. Other approaches such as using measurement scale (P1880) as a mandatory qualifier don't match the intended use of the existing properties, even though the labels may imply they could be used. As a third suggestion, I suppose determination method (P459) could be used with two values--i.e. both a scoring mechanism (paper describing the readability scoring system?) and calculating mechanism (software?). Dhx1 (talk) 23:21, 17 May 2020 (UTC)
        • @Dhx1: I hadn't thought of P1880. Let me think about that one. There is indeed a need to indicate the tool used and applying P459 for both would be suboptimal. BTW Talk:Q2114712 has a summary of measures and different formulas to calculate them. --- Jura 09:23, 18 May 2020 (UTC)
        • @Dhx1: do we have any cases where quantities with multiple, unconverted values really work out? It's already not simple for population numbers or elo ratings. The more I think about this proposal, the more like the initial form. --- Jura 14:05, 26 May 2020 (UTC)

We do not have a proper way to describe the canonical heraldic attitude of an animal or person in a coat of arms. In the early days of 2014, the prototype item Coat of arms of the municipality of Östersund (Q10728131) used direction (P560) for this, but that causes a constraint violation. The item lion rampant (Q3241798) uses has quality (P1552). expression, gesture or body pose (P6022) is the closest property we already have, but I think it would best to create a unique property for "heraldic attitude" with its restricted vocabulary of values (Wikidata has 26 of them).

Commons uses depicts (P180) to describe what's visible in an image. Some images are suitable to illustrate elements that can be expected there, but aren't. Obviously not any value should be used with this property. Generally, there would be another image with that element visible. For the first sample this would be File:T de Pisa, Pisa, Italia, 2019 01.jpg.

Given that does not have part (P3113) is meant for has parts of the class (P2670) or has part (P527), I think we lack a suitable property.

@Jura1: - Okay, now i understand a bit more what you're trying to do with this property (with the COVID example). It would basically be a way to model something like 'empty street' (street depicted without people). I still feel this would be overly complicated, if i want to model an empty street i could simply say: 'depicts empty + street', or perhaps 'depicts street --> qualifier: excluding people'. Husky (talk) 13:27, 13 June 2020 (UTC)
So why would this picture have the 'depicted without Rosa 'Astrid Lindgren' (Q4048433)' property? Husky (talk) 20:01, 18 June 2020 (UTC)
The sign used there "Astrid Lindgern" usually implies that the rose next to it is Rosa 'Astrid Lindgren' (Q4048433). --- Jura 12:06, 21 June 2020 (UTC)
Okay, i kind of get the usecase now, but this property would still be far too ambiguous in my opinion. Should all the pictures of Stan Laurel (Q72869) get a 'depicted without' Oliver Hardy (Q72911) if he's not in the picture? For pictures that might be ambiguous, like the roses you mentioned, i think we can do fine with just captions and/or descriptions on the file page. Trying to model this using Wikidata properties would be both overkill and very hard to explain to people. Husky (talk) 14:46, 23 June 2020 (UTC)

I guess I understand it now but I am still not sure if it makes sense, for absence of an object to be noticeable I would have to have expectation for the object to be there. If a file is named "Portrait of President Obama" but he is not in the photo than it is a problem with a file name that should be corrected, but without a clue based on the filename I do not have expectation to see him in the image.

File:Myrthe Morrees, Lynn Wilms en Joelle Smits - 1578063654.JPG, how to say in Structured data that Myrthe is on the left, Lynn in the middle and Joëlle on the right? series ordinal (P1545) isn't suited, because why should we start counting on the left?

  • Perhaps the label "descriptive position within image", to indicate that the property doesn't intend to actually give the subject's location, but just a vague description. My understanding is that this proposal is purely intended for human readable description and is applicable only to limited images with distinct and few subjects. The specific position coordinates can already be compared to generate such descriptions. --SilentSpike (talk) 11:52, 20 June 2020 (UTC)
    • Well, Wikipedia infoboxes generally have such descriptions, so the number isn't that limited. Oddly, the feature you describe doesn't seem to exist or be used there. Can we see it somewhere in action or is it just an abstract possibility, unlikely to be implemented? --- Jura 12:08, 20 June 2020 (UTC)
      • By limited I just meant a limited subset comparatively to the set of all images, a good example of why implicit points of reference are easy to misinterpret (especially for a machine). As for how that would be implemented, I'm not experienced with editing wikipedia, but my understanding is that they can access Wikidata via a Lua Scribunto interface. Looking at the docs, it seems they could access the statements with mw.wikibase.entity:getBestStatements and compare the x/y coordinates as needed to categorise them corresponding to a lua table of descriptive position strings (or even the above Wikidata items). I'm familiar with lua and it seems like a basic operation, but perhaps (likely) there's some wiki specific implementation complexities I wouldn't know about. --SilentSpike (talk) 16:52, 20 June 2020 (UTC) film ID[edit]

I once added all the official German titles for every instance of Star Trek episode (Q61220733) using the property title (P1476). Someone then deleted those and told me to use name (P2561) instead. Which I did. But I still think, it should be called title. It is just not the actual/official/primary title. So how about having a separate property for localised titles? note that some works might multiple localised titles in the same language (example 6 & 7). --Shisma (talk) 09:36, 23 June 2020 (UTC)

Maniadb is a broad database dedicated to music. We already have album-identifying properties for similar databases such as AllMusic album ID (P1729) and MusicBrainz release group ID (P436), however those websites are in English while this one is in Korean, therefore it may have more records dedicated to albums released by non-Western artists.

In de:WP we have lists of public art of Vienna, e.g. and for some prominent objects even indiviual articles, e.g. de:Mozart-Brunnen (Wien) (these lists always includes the ID used by Wiener Kulturgut). The requested ID allows to link to the map of Wiener Kulturgut, where additional information of each object can be received. The register of public art is also available as Open Government Data.

In Commons there is a template Commons:template:Public Art Austria, which uses the same formatter URL. Skunk (talk) 17:17, 2 July 2020 (UTC)

  • Symbol oppose vote.svg Oppose The IDs are the same as Steam application ID (P1733), and Proton is already listed as a third-party formatter URL for Steam application ID. Lewis Hulbert (talk) 23:48, 5 July 2020 (UTC)
  • Pictogram voting comment.svg Comment I used to be of the same opinion as Lewis Hulbert ; however since I have come to understand that ProtonDB is effectively a subset of SteamDB: all items with an entry in ProtonDB will have an entry in SteamDB ; however the reverse is not true − hence ProtonDB claiming it has "only" 14,227 entries ; while SteamDB has over 147,000 entries.
    If this understanding is correct, then I would lean towards Symbol support vote.svg Support. Jean-Fred (talk) 13:09, 6 July 2020 (UTC)
@Jean-Frédéric: I had not thought about this, thanks for bringing it to my attention, if it were to only have a subset of Steam games that have received a rating I would be willing to support, but storing an exact mirror of the Steam application IDs where 100,000 records contain no additional data seems a waste of time. I've tried looking for some obscure games on the Steam marketplace and checking whether they have a ProtonDB entry and they all have so far, although most have had no reports. The homepage's terminology of "14,227 games reported" makes me think that they have the full Steam data incorporated into their database and the figure is only how many have received ratings by their users. PCGamingWiki automatically adds the ProtonDB link to the infobox whenever a Steam ID is present.[5]. It seems a little bit of a shame to not be able to link to useful information on ProtonDB, I wonder if the creation of a generic property like "compatibility rating" (which we could also use for Wine Application Database (Q63196900)) and storing the values on Wikidata?
