Motivation
[edit]When trying to figure out what images there are available for paintings, I noticed that this is actually fairly complex to determine (see Wikidata_talk:WikiProject_sum_of_all_paintings#Resolution_of_image), The two measures above can help with that. To scale with Wikidata's (or Commons) size, it would be helpful to store them as value rather than to re-calculate on every request. Initially I looked at A3 (Q3410190), but given the available files A4 (Q280184) seems more realistic (Add your motivation for this property here.) --- Jura 10:07, 17 November 2021 (UTC)
