Incorrect use of instance of (P31)[edit]
Hello –
This edit to "Swan Hill wine region" (Q24521756) was in error. The properties instance of (P31) and subclass of (P279) define key ontological relationships. Because subclass of (P279) is transitive, such errors lead to numerous false inferences, such as Swan Hill wine region (Q24521756)instance of (P31)occurrence (Q1190554). Before you use these properties, please look at the value item in your statement to be sure it's the one you intend. You can also review the usage instructions on these two properties, and Help:Basic membership properties. (In particular, note that all instances of a class must be of the same type.) There is often another property that can accurately express the relationship you had in mind; in this case, has characteristic (P1552) works better. You can search through available properties here. Thanks! Swpb (talk) 13:44, 25 July 2023 (UTC)
- Thank you. I didn't know about has characteristic (P1552). Regards. ScottDavis (talk) 03:11, 27 July 2023 (UTC)
