If one would like to toy with this, what files would one look into?

My hazy understanding of this problem looks like this:

- make db models representing persistent state of semantic tags.
fairly easy, but some work.

- implement semanticdb backend interface that talks to the db.

I dont know the cleverest way to do this, but if there isnt some
existing sql interface for emacs, one could implement a little java
prog that serves as a interface to the db. The benefit being the
existence of a lot of jdbc drivers for different db:s, and compilability
with gcj.

And, hmm is that all really?

In fact, with the java route, one could almost machine-map the eieo
tag structures on java classes, that would then be marked up with
xdoclet hibernate tags, and then hibernate could be the persistence
layer into postgres. And the emacs interface to this prog could be a
socket one, or a cmd line one. So if theres no horrible snag like
there being some non-free prog in the chain, it would seems pretty
doable to me. 

Maybe you guys know a more clever route.
