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.
