Discussion[edit]

Link "death of (person)" to item about (person)[edit]

significant person (P3342) seems preferable over participant (P710). What do you think?

place of birth (P19) and date of birth (P569)[edit]

Why are these mandatory constraints necessary? --Trade (talk) 21:24, 16 March 2019 (UTC)

Qualifiers[edit]

In key people of a parliaments I need to included the parliamentary group (P4100) as a qualifier. If it is too much specific, it could be use represents (P1268) instead. Do you agree to add it in a constraint list ?. Thanks, Amadalvarez (talk) 05:30, 4 April 2019 (UTC)

I don't think using significant person (P3342) to indicate people holding positions of significance in parliament in general is a good idea. Positions should be indicated by position held (P39). --Yair rand (talk) 07:05, 4 April 2019 (UTC)

mandatory qualifier constraint (Q21510856) = subject has role (P2868)[edit]

@Arbnos: change added subject has role (P2868) we already have mandatory qualifier constraint (Q21510856) = object has role (P3831) what is your idea how both should be used please give us examples - Salgo60 (talk) 11:58, 4 March 2020 (UTC)

?!?! @Arbnos: I dont follow you when we now look on all items with both subject has role (P2868) and object has role (P3831) does it make sense see list for me it looks like people adds the same value twice in most cases... - Salgo60 (talk) 12:37, 4 March 2020 (UTC)

new swap of mandatory qualifier constraint (Q21510856)[edit]

Change @Jroakes: we cant change this every second week please motivate the change we undid 1 week ago see above - Salgo60 (talk) 01:38, 11 March 2020 (UTC)

Custom constraint[edit]

Can someone create a custom constraint that accepts either subject has role (P2868) or object has role (P3831)? Swpb (talk) 14:56, 13 March 2020 (UTC)

@Swpb: please motivate with some examples... then we maybe can easier request that possibility - Salgo60 (talk) 09:06, 28 March 2020 (UTC)
BoJack Horseman (Q65090308) and the items it connects to with this property. But also, given that this entire talk section is a fight over which qualifier the property should take, isn't it obvious that editors sometimes find one qualifier works better, and sometimes the other?
