Incorrect use of subclass of (P279)
Hello –
This edit to "dry stone wall" (Q544504) 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 dry stone wall (Q544504)subclass of (P279)fabrication method (P2079). Before you use these properties, please look at the object item 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 "A" is only a subclass of "B" if all instances of "A" are also instances of "B".) There is often another property better suited to expressing the relationship you had in mind; you can search for one here. Thanks! Swpb (talk) 20:24, 11 July 2023 (UTC)
