Well - P921 is described as "primary topic of a work", and is an instance of WD property for items about works. Two possible issues:
- "domain" is a much clearer restriction than "main subject/primary topic" - which implies that there may be other secondary subjects. To identifiers, normally the more formal restriction applies. - defining an identifier as a work seems a bit stretched - yet, no domain is given here :-) So perhaps a new property is needed?
