Connecting SDB to Protégé

[xavier aimé]

Dear List,

I would like to connect Protégé to my persistent ontology in SDB. But, 
there's no connectors between Protégé and triple stores. I know that 
TopBraid Composer can do that, but it's the standard edition (not free 
edition).

So, I would like to know (i) if it is possible, (ii) and what's the best 
solution.

Thanks in advance,

         XA
