This property should be a qualifier[edit]
This property should be a qualifier, because any person can have more than one occupation in their lifetime. -Theklan (talk) 07:32, 2 December 2021 (UTC)
- Came to this discussion following a similar issue with music bands such as Westlife (Q151241). I agree with Theklan, but haven't found documentation for the right qualifier for that. Should it be series ordinal (P1545)? Eran (talk) 09:54, 1 March 2024 (UTC)
I do not see the constraint violation with date of death Oursana (talk) 11:49, 15 January 2024 (UTC)
- There was problem with uncertain dates. I've fixed it somehow. --Infovarius (talk) 19:31, 16 January 2024 (UTC)
