So, okay, the "value added" stuff you have will indeed be relationships
between entities, which is not too unexpected.
So, yes, I would want a real-time query service (for enhancement of
individual items on display in my system) _as well as_ a bulk download
(for enhancing my data on indexing).
For real time query, I'd have a specific entity at hand roughly
corresponding to a 'manifestation'. I'd want to look it up in your
system by any identifiers I have (oclcnum, lccn, isbn, issn; any other
music-related identifiers that are useful?) to find a match. Then I'd
want to find out it's workset ID (or possibly expression ID?) in your
system, and be able to find all the OTHER manifestations/expressions in
those sets, from your system, with citation details about those items.
(Author, title, publisher, year, etc; also oclcnum/lccn/isbn/issn/etc if
available. Just giving me Marc with everything might be sufficient).
If you have work identifiers from other systems that correspond to your
workID (OCLC workID? etc), I'd want to know those.
For bulk download, yeah, I'd just want everything you could give me,
really.
Some of the details can't really be spec'd in advance, it requires an
interative process of people trying to use it and seeing what they need.
I know this makes things hard from a grant-funded project management
perspective.
