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 (manual list) and Special:ListProperties.
  2. Check if the property is already pending or has been rejected.
  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. Change status=ready on template to attract the attention of a property creator.
  2. Creation can be done after 1 week by a property creator or an administrator.
  3. See steps when creating properties.

book series[edit]

   In progress
Description серия, в которой выпущена книга (ru) – (Please translate this into English.)
Represents book series (Q277759)
Data type Item
Domain book (Q571)
Allowed values instances of book series (Q277759)
Example Advances in Cryptology — CRYPTO ’86 (Q21721313), Advances in Cryptology — CRYPTO ’87 (Q21704688), Advances in Cryptology — CRYPTO ’98 (Q21722638) -> Lecture Notes in Computer Science (Q924044)
Source for example param "серия" of ru:w:Шаблон:Книга; Google Books; etc.
Robot and gadget jobs will be used by book editing gadget and by w:ru:Модуль:Source to build book reference text.

At this moment Project:Books advices to use of published in (P1433), but distinct property is better. It is much simple to check single property (in LUA) and find out book series instead of generic property along with complex condition checks like "if it's a book, we will call it series, otherwise we will call it book/journal/something else".

  • Oppose--use series (P179) or 1433 as advised. --Izno (talk) 23:56, 13 August 2015 (UTC)
    • @Izno: it is not series (P179), because P179 is about creative work, and proposed property is about specified printed book. Different books can contain same work with the same value of P179, but with different book series. And also current proposal is about to "extract" the described cases from 1433 property, so your argument "use 1433" can't be understood. -- Vlsergey (talk) 08:16, 17 August 2015 (UTC)
      • Take a look at the type constraint report. I don't think this property is being used to indicate a creative work (unless you count phones and cars among such). And I've used it myself to indicate the inclusion of books and characters in a series (whether singular or multiple). Your example does not make it clear how this property (P179) is the incorrect property to use.

        As for 1433, I don't see why extraction is called for. --Izno (talk) 14:19, 17 August 2015 (UTC)

@Izno: Okay, let me provide more detailed example with explanation why P179 is different:

  • Creative work Day Watch (Q2714888) is part of no label (Q20826824). It is what P179 is about and shall be used, i.e. P179 is creative work (FRBR work) property. This creative work was published as part of several books:
    • ISBN 5-17-008349-1 -- 2006 year -- as part of book series called "Звездный лабиринт"
    • ISBN 978-5-17-084937-6 -- 2014 year -- as part of book series called "Проект Сергея Лукьяненко «Дозоры»"
    • ISBN 5-17-025883-6; -- 2004 year -- out of any book series
  • Thus, i need a property used strictly for FRBR item (not FRBR work). It is possible that single Wikidata item will have both P179 and new property specified, but with different values. -- Vlsergey (talk) 14:57, 17 August 2015 (UTC)
Vlsergey, FRBR 'item' is wikidata 'edition'. Yes? Each edition has a publisher (P123) which could sort of do this however many publishers have separate brands which they use for different niches. Penguin Books ( Q1336200) has Puffin Books ( Q4907694) for kids and Pelican Books ( Q17092380) for non-fiction; Gollantz Science fiction books all had yellow covers; Harlequin has multiple 'imprints' for different types of romance novels. I know that many publishers of translations have separate brands for detective, science fiction etc. Is that what this property is for? Could we just use publisher (P123) and have separate items for each brand/imprint with owned by (P127) to indicate which conglomerate owns each of these? I see that Template:Книга ( Q909529 ) has separate items for 'series' and 'publisher' but it isn't clear what the difference is. If this really is a different property then I want to make sure the English description makes clear what it is for and what it is not for and I don't think we are there yet.Joe Filceolaire (talk) 13:14, 24 August 2015 (UTC)
@Filceolaire: it is close by description, but different in details. In Russia publishers do not use different brands, but merge books using same cover style. The most famous, IMHO, are Library of adventure and science fiction (Q4086379) and no label (Q4180211). This "book series brand" can be used by different publishers, and according to our bibliographical description standard (ГОСТ 7.1—2003) "seria" ("Область серии") is a distinguished field from "publisher" ("Область выходных данных"). -- Vlsergey (talk) 13:42, 24 August 2015 (UTC)
Thank you Vlsergey. Can you try and add statements to Library of adventure and science fiction ( Q4086379) to give us an idea as to what a typical 'book series' is? From the google translation of the russian wikipedia article (ru:Библиотека приключений и научной фантастики) it looks like it is a publisher. The article specifically says the brand is copyright and the various versions of this in the post soviet era from other publishers all seem to use slight variations of the name to distinguish themselves so they don't infringe on the brand - in looks like the "book series brand" cannot used by other publishers. Joe Filceolaire (talk) 14:36, 24 August 2015 (UTC)
@Filceolaire: found another good example, already filled with some properties: Lecture Notes in Computer Science. It is owned by single publisher as well (it may be usually the case), has a lot of books inside (~2k) and common topic. And it is obviously about topic and representation, not about content (i.e. no common characters, no common "world"). Regarding brands. "Lectures" are published under brand "Springer Berlin Heidelberg", but some of the books under "Springer Science+Business Media". I.e. it is not "publisher" field value to use. The thing i need is "series" field of w:BibTeX book format (and it is different from "publisher" field). -- VlSergey (трёп) 07:55, 17 December 2015 (UTC)
  • Symbol oppose vote.svg Oppose Use series (P179) or collection (P195). Swpb (talk) 14:00, 2 February 2016 (UTC)
    • They are completely different. P179 is about content (i.e. FRBR Work, not about book), P195 is about physical place of single item. -- VlSergey (трёп) 10:22, 11 February 2016 (UTC)

PlayStation ID (or similar)[edit]

   In progress
Description A property to input the unique identifier of PlayStation software and hardware assigned by Sony Computer Entertainment Inc.
Data type String
Domain PlayStation hardware and software
Allowed values string pattern yet to be defined
Source External databases, game covers, etc.
Robot and gadget jobs There is potential for automation by using existing external data sets e.g.

All software and hardware released for PlayStation consoles (and even the consoles themselves) is assigned a unique reference by Sony Computer Entertainment Inc. This helps correctly identify a product, especially where two or more products share the same name. For example, Ridge Racer (PS1, PAL) is SCES-00001 and Ridge Racer (PSP, PAL) is UCES-00002. This property would be similar to existing Wikidata video game reference properties such as Metacritic ID, Steam ID or MobyGames ID. Macrike (talk) 14:39, 1 January 2016 (UTC)


Italian Senate ID[edit]

  • Pictogram voting comment.svg Comment the English version of your proposal reads "Chamber of Deputies" so it looks like you would be asking for the same. I suppose you mean "Senate".

    Obviously. I copy-pasted the old proposal for the Chamber of Deputies ID and I forgot to correctly change it. Thank you --★ → Airon 90 18:19, 10 January 2016 (UTC)

BookBrainz creator ID[edit]

   In progress
Description identifier for a creator per the BookBrainz open book encyclopedia
Data type String
Domain human (Q5)
Allowed values The same of MusicBrainz, if present
Example Arto Paasilinna (Q211542)5291de51-0ec8-473e-98a3-baf5a7500ef3
Format and edit filter validation The same of MusicBrainz, if present
Formatter URL$1

BookBrainz is the MusicBrainz of books. I think this sentence is sufficient. ★ → Airon 90 09:52, 11 February 2016 (UTC)
