"List of qualifier"-query in property documentation template (see top right corner of property talk pages)[edit]
The query used to time-out on some of the frequently used properties. For properties with many uses it now offers a query that checks only the first 0.5 - 1 million statements. --- Jura 12:22, 27 June 2020 (UTC)
use of "novalue"[edit]
For place of birth (P19) and place of death (P20), some qualifiers are used, but many aren't that frequent and some frequent ones aren't currently recommended AFAIK (e.g. country (P17) or located in the administrative territorial entity (P131) which should be on the item used as value, not as a qualifier -- some old bot story).
Accordingly, I set P8379 to novalue. --- Jura 12:22, 27 June 2020 (UTC)
value for date of birth (P569)[edit]
instance of (P31) seems to be the most frequently used, due to a bot tagging them with it.
- instance of (P31) is not a property that should be used as a qualifier.
- Even if the bot hadn't used P31 I don't think the "most frequent" one would be useful for manual editing.
Accordingly, I set this property to sourcing circumstances (P1480) which is occasionally useful. --- Jura 12:22, 27 June 2020 (UTC)
How many values? sample: spouse (P26)[edit]
Current situation:
Uses of P26 | 236,968 |
---|---|
start time (P580) | 34717 |
end time (P582) | 21332 |
place of marriage (P2842) | 2736 |
end cause (P1534) | 1902 |
series ordinal (P1545) | 727 |
I hestitated between adding start time (P580) or the first three of the above. --- Jura 12:43, 27 June 2020 (UTC)
Duplicate required qualifier constraint (Q21510856)?[edit]
Should these be copied or not? I skipped them for now --- Jura 12:43, 27 June 2020 (UTC)
Update qualifier suggestor to use this?[edit]
Currently, the suggester works with the property constraints (see Help:Property constraints portal/Entity suggestions from constraint definitions.
Should this be updated to this property? --- Jura 12:43, 27 June 2020 (UTC)
