Hi,
One approach to the UI might be to use Cooliris (was piclens) and generate
a media rss file in call number order. It's limited (to people who have
installed cooliris) but it's essentially a coverflow. You can do other
things within the browser, but few are going to feel as immediate and
tranparent to the user.
Again, maybe not for all users, but maybe a cool enhanced version for a
subset.
Generating that media rss file may get tricky (you need uris to thumbs and
"fulls") depending on the API from, and agreements with syndetics.

Depending on what you want to do exactly, yes. Look at
Querying Ontologies in Relational Database Systems - ►hu-berlin.de [PDF]
S Trissl, U Leser - LECTURE NOTES IN COMPUTER SCIENCE, 2005 - Springer
If you need more you're looking at CS literature concerning treatment of
graphs, directed graphs, cyclical, transitive closure, etc.
This can all be done without to much difficulty but as Nate pointed out
updating the data is a problem...I've not tackled that part but there is much
literature on dynamic graphs and I'm assuming this could also be adequately
solved.
a decent UI is probably going to be a bigger job
Yes, that's the real issue. Could call numbers be placed within a hierarchy? Then
display this in an outline view (Windows Explorer) that is also item searchable? Seems
to me there is structure in the call numbers that is hidden in current UIs. I also think
the actual "Call number" should disappear and replaced by a textual label
describing what the numbers mean.
Fun stuff to think about...

Subject: [CODE4LIB] creating call number browse
Hey all,
I would love to tackle the issue of creating a really cool call number
browse tool that utilizes book covers, etc. However, I'd like to do this
outside of my ILS/OPAC. What I don't know is whether there are any
indexing / SQL / query techniques that could be used to browse forward
and backword in an index like this.
Has anyone else worked on developing a tool like this outside of the
OPAC? I guess I would be perfectly happy even if it was something I
could build directly on top of the ILS database and its indexes (we use
SirsiDynix Unicorn).
I wanted to throw a feeler out there before trying to dream up some wild
scheme on my own.

P.S. The version of BiblioCommons released at Oakville Public Library
has a sweet call number browse function accessible from the full record
page. I would love to know know how that was accomplished.
