interess for the property inverse? edit

Hello,

I find usefull to create the inverse property of recording or performance of (P2550). The label is already existing recording/performed version (Q67006033).

What do you think about?

Hello SAPA bdc  . In RDF, a triple reads in both directions. Therefore a property normally doesn't need an inverse property; it only needs an inverse label so that humans can easily read the triple in reverse direction. The human readable interface of Wikidata however doesn't make inverse statements readily visible. One has to clink on "What links here", in the tools menu, or open up the "Derived statements" at the bottom of the item. Or else these inverse triples can be retrieve via the query service.
This being said, in Wikidata, certain important properties do have inverse properties. The most notorious one is part of (P361) and its inverse property has part(s) (P527). This relationship particular is structurally quite fundamental, so I presume this inverse property was created to ensure the relationship would be visible to human readers on both ends of the triple.
Inverse properties should however generally be avoided, because they multiply the editing effort by two : a given triple has to be populated twice. Therefore, I would not recommend creating an inverse property for recording or performance of (P2550). Fjjulien (talk) 02:54, 3 December 2021 (UTC)Reply

Conflicts with "“instance of (P31): release (Q2031291)" ? edit

Hi. I don't really understand this constraint: Conflicts with "instance of (P31): release (Q2031291)". Why is release(Q2031291) in conflict when all it's subclasses are okay? The description reads, "item is a recording or release of this composition" The Domain says, "items with instance of (P31) of release (Q2031291) or its subclasses"

I'm really confused. But I'm also pretty inexperienced in reading these property constraints. Thanks --Metadatum (talk) 01:10, 23 April 2022 (UTC)Reply
