Actually Publisher and Creator are subclasses of contributors but certainly not of Actor. Actor is also a subclass of Contributor.

I mean IsA vs. a XML like name of an element like 'Title' vs 'hasTitle'

same here.

A small question though:

why are Publisher and Creator not subclasses of Actor, while Contributor
is ?

I would have expected Creator, Actor and Contributor to be subclasses of
Actor, as well as Person and Organization -- although of course the
Creator/Actor/Contributor distinction is orthogonal to the
Person/Organization partition...

by this, do you mean "is-a" vs. "isA" ?

I agree with that.
