Sorry not tried it in - but the javadoc says it does work at the Jena
Graph level (the lower level interface) which is the right place to hook
in.
It's a object-copying adapter, converting to it's object model
(java.net.URI, blank node, it's own literal implementations). Blank
nodes wrap the underlying system blank node - amusing way to do it.
An alternative store abstraction is to use SPARQL (QL and protocol)
which would then work for non-Java stores as well.
seeAlso: There is project to do a JDBC driver for SPARQL (SPARQL4j) on
SourceForge.
http://sourceforge.net/projects/sparql4j/ (despite being named on the
project, I'm not active).
