Constraint violations

Wikidata:Database reports/Constraint violations/P1709

This property has 377 constraint violations i.e. items that doesn't use it as qualifier. We should think about the concept.--Bigbossfarin (talk) 20:49, 1 April 2017 (UTC)

It appears that all the violations are gone. Peter F. Patel-Schneider (talk) 23:14, 16 October 2018 (UTC)

not equivalent to exact match

This property is for classes only whereas skos exact match is for anything. Thus they cannot be equivalent. I've deprecated the claim. Peter F. Patel-Schneider (talk) 23:11, 16 October 2018 (UTC)

@Peter F. Patel-Schneider: Is this a subproperty of exact match?--Malore (talk) 02:14, 31 October 2018 (UTC)

It seems to me that it is. Accordingly, I've added the statement subproperty of (P1647)exact match (P2888). Silver hr (talk) 13:47, 3 August 2022 (UTC)
