Well, strictly speaking, it's not *all* QDC specifically. You can
define as many additional schemae as you want. But they all have to
be one- or two-level hierarchies (like QDC) so some models would be
quite difficult to represent. Shallow hierarchial models are what
DSpace can use to support basic searching and browsing. If you can
express it as a tuple {schema, term[, qualifier]} then it is
manipulable in DSpace.
IIRC other types of metadata representations can be stored as
bitstreams, though they can't be directly used by DSpace. They would
be bound to their Items and available for use by other tools.
I guess it would be fair to say that DSpace concentrates on doing IR
well, but tries not to get in the way of people who are willing to
extend it to do other things well.
