Jurisdiction

The jurisdiction is imported and should be a country/state. Could someone make applies to jurisdiction (P1001) mandatory? --Hannolans (talk) 09:31, 24 April 2017 (UTC)

I found out how to enable this with properties. --Hannolans (talk) 14:24, 25 April 2017 (UTC)

Restricted to literary and artistic works?

A public domain date can only apply to literary and artistic works, databases (in some jurisdiction), inventions (in case of patents). It cannot be applied to persons as the term of protection for works created by that person might differ per work. Can we restrict this property to disallow its use at persons? Martsniez (talk) 15:26, 26 January 2018 (UTC)

@Martsniez: agree, added the constraint. It only gives three results right now: H. G. Wells (Q42511), Gertrude Stein (Q188385) & Príncipe Pretinho (Q16930304). Multichill (talk) 22:27, 26 January 2018 (UTC)
