Yes, I agree. I'm planning to get us started on this thread as soon as
student research help shows up with the beginning of the academic year
here.

No too esoteric. Any discussion of web metadata frameworks need to
follow a parallel track - on the one hand 'constrained' by the current
limited web architecture, on the other hand how the web architecture
should be expanded to allow better expression of semantics.
