I guess the basic minimum would be P580 (start time) and P582 (end time), if applicable.

Hi all,

Too many items on Wikidata still miss the basic statements. Perhaps we can focus together for a short period of time on a single subject to get this fixed.

For example: all items with instance of (P31) some sort of armed conflict should also contain the point in time (aka start time).

When I just ran a query I saw about 1300 conflicts that are still missing the time.

Query: https://query.wikidata.org/#SELECT%20%3Fitem%20%3FitemLabel%20WHERE%20%7B%0A%20%20%3Fitem%20wdt%3AP31%2Fwdt%3AP279%2a%20wd%3AQ71266556%20.%20%23%20and%20are%20some%20kind%20of%20armed%20conflict%0A%20%20MINUS%20%7B%0A%20%20%20%20%3Fitem%20wdt%3AP580%20%3Fsomething%20.%0A%20%20%7D%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%22.%20%7D%0A%7D%0A

Who has ideas and can help getting this statement added to all the items about ports?

Thanks!

Romaine
