I'm fuzzy on the criteria for a semantic database, but SPASQL is a
project aimed at providing RDF access to conventional relational data.
There's a project page [SP], a talk I gave at XTech [SX] and a cvs
repository [SC].
At some point, I'd like to add a triple store for stuff that doesn't
fit in the relational schema. This is prototyped in FeDeRate (Algae2
test case [TC]). Also want to port the query federation stuff to the
MySQL implementation (use case [FD]).
Steve Harris, of garlik.com, has implemented a triple store, but not
within MySQL. He might be interested in this work.
