Motivation

When Wikimdia Taiwan offered a story from Li Mei-shu's edit-a-thon, that story said that the standard does not appear in the property of Wikidata. Therefore, I propose this property to mark the oil paintings. Taiwania Justo (talk) 03:55, 10 April 2018 (UTC)[reply]

WikiProject sum of all paintings has more than 50 participants and couldn't be pinged. Please post on the WikiProject's talk page instead. Taiwania Justo (talk) 06:16, 10 April 2018 (UTC)[reply]

Support we should probably note that while "French" is in the name, it is a widely-used size standard for all paintings on canvas, no matter the country of origin. ArthurPSmith (talk) 21:27, 10 April 2018 (UTC)[reply]
@Taiwania Justo: The allowed values and example given above do not match those in the Wikipedia article suggested as a source; can we have some clarity please? If there are a reasonable, finite number of forms, the datatype should be "item". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:30, 10 April 2018 (UTC)[reply]
- @Pigsonthewing: Roger that. I changed to the "item" first. If any evidence about the "string" form of the property is appeared, we can change it back. Taiwania Justo (talk) 00:56, 11 April 2018 (UTC)[reply]
  - The source has given on the information above. Taiwania Justo (talk) 01:07, 11 April 2018 (UTC)[reply]
Comment If you make items for these, couldn't you link them with aspect ratio (W:H) (P2061) from paintings? On the items, the string should be available in a format other than the label. Maybe this property with string format could be used there.

Comment Item datatype allows you to specify the dimensions on the target item, so that seems useful. Obviously aspect ratio (W:H) (P2061), while related, is quite different (and most of these various sizes have very close to one or two standard aspect ratios anyway).

- So where would the string "M40" go?

  - What's wrong with the label? We don't do anything special for other categorization items like endangered species (Q11394) right? Or a little closer to this one, A4 (Q280184) - that has no string property set to A4. ArthurPSmith (talk) 20:39, 18 April 2018 (UTC)[reply]
