All,

I noticed reference to the above in the minutes of today's meeting. I 
would like some clarification of what is sought here. For instance, is 
it SPARQL down the JDBC channel and RDF back but serialized as a SQL 
resultset in form palatable to JDBC? Or are we looking of an RDF graph 
exposed as a Java Object via JDBC?

At the current time Virtuoso already supports SPARQL via JDBC using 
SPASQL (SPARQL inside SQL). This is how the Virtuoso Providers for 
Sesame and Jena have been implemented. Likewise, SPARQL via ODBC is how 
we implemented the Redland Provider.

In all of the cases above you have access to physical and virtual 
triples (over native Virtuoso SQL, 3rd party ODBC or JDBC accessible 
data sources amongst others).
