Gabriel Roldan (cced) I believe has been working on database catalog 
stuff in Java with GeoTools.  He may have some code that you could 
reuse.  He's focused on CS-W2, but there may be some backend stuff you 
could use.  He's also looking to make it a plug-in to GeoServer's new 
modular architecture, run it as a service there.

Even if there's not much code overlap, it might be interesting to try to 
incorporate some of your stuff to the GeoServer architecture.  It's now 
spring based, which I think should be compatible with what you're doing, 
and it could ship as a plug-in to GeoServer and as a stand alone app 
built on the same architecture.  Just something to think about, I like 
your approach a lot, it's in line with what I've been thinking about 
recently.

Also note that the coming Feature Model stuff in GeoTools is an POJO 
abstraction of geospatial objects, and should be rich enough to handle 
even more complex metadata elements, and also be able to give simpler 
views on them.

best regards,

Chris
