"opposite of" vs "inverse of"

@Matěj Suchánek: There is only one property for "inverse of" (for properties), and it has the alias "opposite of". Is opposite of (P461) supposed to be used? Jc86035 (talk) 04:23, 30 May 2017 (UTC)

Something like that should be used since "inverse of" means that the second property should link back to the first one, which is impossible with datatypes other than entites. Sadly, opposite of (P461) has item datatype which doesn't work with properties. Matěj Suchánek (talk) 06:18, 30 May 2017 (UTC)
