| See also | excluding (P1011): the labels and aliases of excluding (P1011) suggest completeness, i.e. that its values should cover all exceptions, rather than provide examples. excluding (P1011) is also used to exclude parts of the parent entity, in addition to instances or subclasses of it. |
Motivation edit
Used to provide counterexamples to clarify deprecation of subclass of (P279) statements with reason for deprecated rank (P2241) = not all instances of the item are instances of the value class (Q118134102), where such examples are useful, e.g. when counterexamples are not obvious. This will be a curated Wikidata property (Q121928698). Swpb (talk) 18:58, 1 November 2023 (UTC)
