chronology[edit]

Can this property point to chronology (Q130788) items? E.g., can Universe (Q1) have history of topic (P2184) of chronology of the universe (Q136407)? Runner1928 (talk) 17:52, 6 October 2015 (UTC)[reply]

Done - Mbch331 (talk) 18:42, 6 October 2015 (UTC)[reply]

Multi-history[edit]

What would you say about this kind of change? In big subjects, there are often more than one article describing the history. And while some of you refer "The Swedish Empire" as a historical nation, I would prefer to describe that article as one of a group articles about the history of Sweden. -- Innocent bystander (talk) 12:18, 17 October 2015 (UTC)[reply]

There is no constraint on single value. So I don't see any problem with that change. Mbch331 (talk) 19:38, 18 October 2015 (UTC)[reply]

To-do list[edit]

This query shows a lot of items that should have P2184 statements pointing to them. --Yair rand (talk) 04:44, 27 November 2018 (UTC)[reply]

Main article must have "facet of..." ?[edit]

This constraint seems incorrect. A "history of" is a facet of main topic. Main topic is not a "facet of" any of its daughter sub-topics. Or is it? Retired electrician (talk) 00:06, 14 December 2022 (UTC)[reply]
