Use for Wikipedia? edit
Can we use this for the number of articles on items about Wikipedia language versions?

- @Jura1: I'd rather use number of parts of this work (P2635). --Marsupium (talk) 08:17, 13 June 2018 (UTC)
Use as qualifier for Stack Exchange tag (P1482)? edit
@Jura1, Marsupium: WikiProject Properties has more than 50 participants and couldn't be pinged. Please post on the WikiProject's talk page instead.
Hi! I want to add this as qualifier to Stack Exchange tag (P1482) to state that (see https://www.wikidata.org/wiki/Q2539#P1482):
- machine learning (Q2539) has tag https://stats.stackexchange.com/tags/machine-learning with:
- number of records: 19,909
- point in time: 10 September 2023
- applies to part: question (as opposed to answer, user)
So I've added to this prop:
- property scope constraint
- property scope
- as main value
- as qualifier
- property scope
Do you agree in general?
And another question: I get a warning that "point in time" cannot be applied to Stack Exchange tag (P1482).
- And that's correct: here "point in time" and "applies to part" are sub-qualifiers (qualifiers to the qualifier, not to the main snak).
- Wikidata doesn't support such complex constructs, and I'd rather not create a sub-object for "Machine Learning on stats.stackexchange.com"
- So do you agree with this slight twisting of the semantics?
