Property proposalsEdit

  • some "folio" property? Commons has c:Template:Folio, see also page(s) (P304), column (P3903)
  • ArchDaily architecture office ID:
  • logic:
    • "statement reference" qualifier (can be omitted for formulas with only one operator type), probably numbered values "1", "2" etc.
    • "statements logics"/"statements relations"(?): as qualifier somewhere? (in the formula the referral statement could be represented by e.g. "THIS" (stupid idea?)) easy to complex formulas like simple "AND" (could be added as a qualifier to several) to "((2 XOR 4) AND 3) OR (1 AND NOT 5)" (how many operators shall be accepted?): not well formalized, but I don't see an alternative; TODO: find good examples and further consider with them (a less powerful alternative would be qualifiers "or" and "and", but really not expressive, error-prone and bad with information in qualifiers, so: no!)
  • museum etc. place identifiers (because new items are stressful, and currently probably partly less structured ("followed by" should be used more (also by me); and "shares border with")):
    • "room reference" (datatype: string; cf. OSM key "ref"; number, letter etc.: format constraint Unicode classes!): corresponds to (superclass of (doc says only number)) |1= of c:Template:Room: is sometimes script-dependent (e.g. Baituna al-Tahami Museum): then only use at the room item with writing system (P282) qualifier
    • "showcase reference": see above; some differentiation for room specific vitrine references?
    • "department": a department property with item datatype instead of the current method with special solution for the Louvre and others at Commons??? see 2018-12-19's Wikidata:Property proposal/organizational unit
  • "stated in official website of" (we often don't and also do not want to a have a separate item for the website I assume?) – Probably this can be simply solved by using "publisher" (or a similar property)?? (also: how to crosscheck with "official website"?) (03:58, 14 August 2018 (UTC))

Why the "sum of all paintings" isn't such a good scopeEdit

See Paragone (Q392398): Leonardo – Vasari. It is eurocentristic. See de:Kunstgattung#Probleme des Gattungsbegriffs.

(offtopic: an interesting question:

  • Property mapping (adapted from Wikidata:WikiProject Visual arts/Getty Vocabularies#Ontology mapping):
    SELECT DISTINCT ?wdProp ?wdPropLabel ?relationshipStProp ?relationshipPropLabel ?extProp ?singleValue
