Resolution status:

API:

I find this spec a little confusing, though it's helped by the concrete
examples of use. You are right to identify local/internal and
remote/external sources for metadata, but the API doesn't feel very
Javascripty to me.

I think the approach of so many different specialized typed interfaces
may be too cumbersome for both implementers and authors. I would take a
more combinatorial approach, where the author uses the API to extract
sets of metadata via certain selection criteria, then further filter
those with selection criteria, or iterate through them generically and
programmatically.

It seems that you are considering the case of multiple instances of
orthogonal or even conflicting metadata, possibly in different formats,
being extracted from the same media resource (thus the returnset being
an array), but I couldn't see that explicitly described anywhere.

I realize that these are pretty high-level comments, but I'm happy to
join a telcon sometime to discuss them further, or expand on them via
email. Unless you have specific implementer feedback about these, I
think it might be fruitful to reexamine this approach before the CR phase.
