Happy New Year!
 
(I'm awake again ...)
 
I think we've got two separate areas of focus: 1) the "obtain" function; 2)
granularity of metadata description. Both are interesting.
 
1) is concerned with a specific item (although it may be distinguished from
other items of the same manifestation merely by its "obtainability"), and covers
attributes such as loan status, opening hours for physical access, access
restrictions based on licenses, etc. as well as bibliographic attributes which
make a specific item "special" (e.g. missing pages, autographed by author,
previously owned by a specific person or group, etc.).
 
2) is concerned with what is being described by metadata: (in descending order
of granularity) a super-collection, a collection, a work and all its
expressions/manifestations/items (the traditional bibliographic record), a
specific expression/manifestation/item (a FRBRised "record"), a specific
attribute of a specific resource (an RDF triple).
 
I think we need to cover both areas in the LLD work, but not necessarily via the
use-case cluster mechanism. 1) definitely needs the use-case approach, but 2)
could be handled by adding a page to the wiki's Resources section (perhaps via
the Library standards and linked data page). As we've already discussed, neither
collection-level description nor FRBRised description are generally used by
libraries at present, so 2) is more hypothetical than practical. Of course, we
could just add two use-case clusters, one for each focus ...
 
I'm happy to add a wiki page on granularity (for 2)) if that's the approach we
agree on.
 
Cheers
 
Gordon

It depends how we define the cluster -- whether it's about "obtain" or about
collections.
