[Data-modeling] Types for subjects

[Ed Laurent]

I like the idea of having a single "Media subject" type. Another option
might be to keep all the existing types and have them include or delegate
from the new generalized type. Then the existing subject types could be
evaluated on a case by case basis by base members to see if they should be
deleted or merged.
