New request for comments: Community request for the development team to access inverse properties on client wikis. (Summary: We currently cannot access inverse property values on Wikipedia. This can be a data management issue on Wikipedia as we must always ask ourself if we must introduce an inverse property for cases where we need them. So I think it’s useful to gather the usecases community would want and draft a request for an API to the devteam to do that.)
