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?

Perhaps that could be derived from the type constraints in linked
properties, but I think it would make sense as an explicit property on the
Main subject (P921) ?
I certainly don't think users should have to query properties to find metadata
