Sure. All these use cases stand and can co-exist. I can look at the
data in any of those responses, or data I glean from elsewhere, to
figure out if the URI I'm accessing refers to the content I received
or the subject of that content. That model works for any protocol BTW.

OK, we differ here then. I would prefer to bookmark the movie because
that's what I'm interested in. The page will change over the years but
the movie will still persist. Today you have no choice because your
conceptual model does not give a URI to the movie and doesn't see the
need to generate 2 URIs.

i don't think this has anything to do with microdata.
