What is the reason for the P1629 constraint? edit

I don't understand this constraint:

Property "Wikidata item of this property (P1629)" declared by target items of “subproperty of (P1647)”: If [item A] has this property with value [item B], [item B] is required to have property “Wikidata item of this property (P1629)”.

That is, I understand what it does (I believe), but I don't understand the reason. NisJørgensen (talk) 14:03, 25 July 2019 (UTC)Reply

incorrect claim in core of Wikidata ontology edit

I see the claim here that subproperty of (P1647) subproperty of (P1647) subclass of (P279).

Surely this is incorrect. But the real question is how such a core incorrect claim can have persisted since September 2019 without anyone noticing. Is there any way to protect the core items of the Wikidata ontology from bad changes? Is there nothing in Wikidata that would flag material changes to the core items of the Wikidata ontology?
