[Data-modeling] Types for subjects

[Jeff Prucher]

What you're proposing is an even more general type than what's proposed in
DA-445, and wouldn't really address that issue at all.  I kind of think that
having a "media item with subject" type, with only a property for subject,
wouldn't really get us much.
