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 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. 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.

Description is an encoding of or stands for
Data type Item
Domain code (Q188889)
See also notation (P913) is the reverse for some examples

Codes and other signs such as character encoding (Q184759) and data format (Q494823) relate code symbols to other entities. This property should allow to express the encoding relationship for both single codes and full encoding systems. Aliases for some examples are "serializes" (e.g. RDF/XML (Q48940)Resource Description Framework (Q54872)) and "stands for" (e.g. heart (Q826930)love (Q316)).

Update: for some cases depicts (P180) does the job, for others a reverse of notation (P913) would be needed.
currency symbol description (P489) is a subproperty of notation (P913) which is the reverse of the proposed property for some examples. Do you oppose the broad application of the proposal, so should I better propose a more specific sub-property? --JakobVoss (talk) 11:24, 15 June 2016 (UTC)

  • Pictogram voting comment.svg Comment if this is to be item datatype, the example should show a link to an item, not a text string. Also a few more examples (including a matronymic surname) would be nice. ArthurPSmith (talk) 13:58, 14 July 2016 (UTC)
    • There is no item for "Jóhannesson" yet.

has grammatical case[edit]

Description the cases a language has
Data type Item
Domain languages
Allowed values all grammatical cases
Example German (Q188)dative case (Q145599)

I want to make queries about which languages have which cases. Or which languages have the most cases. Tobias1984 (talk) 19:50, 5 July 2016 (UTC)

  • Symbol support vote.svg weak support - the classification of cases a language has seems useful without straying too far into linguistic information that is Wiktionary's domain. I'm not sure though whether analysing which languages have the most cases is entirely valid the further from Indo-European languages you get? Thryduulf (talk) 22:03, 5 July 2016 (UTC)
  • Symbol oppose vote.svg oppose - External sites and data already contain this information your looking for, such as WALS that has CC-BY data, where we already have the WALS lect code (P1466) that should ideally be filled in for all languages. I would say, its more useful to fill that property instead of creating this new property. Thadguidry (talk) 16:17, 7 July 2016 (UTC)
I don't see how the fact that an external site contains this information means that Wikidata shouldn't have it. ChristianKl (talk) 19:50, 8 July 2016 (UTC)

  • Can we have a more general property? Maybe something like "has gramatical feature"? ChristianKl (talk) 19:50, 8 July 2016 (UTC)
    • @ChristianKl: That would be a possibility too. In that case the example of German also has different times (Pluperfect (Q623742)), a plural form (plural (Q146786)), honorific form(honorific (Q1326966)), article (article (Q103184)) with different genders (qualifiers?). Also the you form is gender neutral (as opposed to Turkish and Arabic I think). Your suggestion would gather much more statements per item, and I can't think of a downside for querying. --Tobias1984 (talk) 09:27, 10 July 2016 (UTC)
    • As there should be several values for this property, I don't think it's an advantage to combine it with other things.
      --- Jura 05:32, 11 July 2016 (UTC)
    • If we broaden it to that, I would prefer has quality (P1552). --Izno (talk) 11:46, 13 July 2016 (UTC)
  • Symbol support vote.svg Support. I think it's a good way to start.
    --- Jura 05:32, 11 July 2016 (UTC)
  • Symbol support vote.svg Support seems to be useful. We should think about properties for tenses and genders etc. -- T.seppelt (talk) 14:29, 17 July 2016 (UTC)
