Thanks Patrick,
I see that Sesame does have an implementation of Trippi so I guess it
would be possible to use Virtuoso through it.
My program already accesses Virtuoso through tha Jena provider, I guess
I'll change it to use the Sesame provider, put Trippi on it and see how
it all works together.

Hi Alex,
This one goes to Virtuoso devs.
Is there a release or are there plans to develop a Trippi Connector for
Virtuoso Triple Store?
http://trippi.sourceforge.net/implementation-guide.html
I would like to test Fedora Commons Repository backed by Virtuoso OS
both as its relational database and as its resource index (triple store)
to reduce number of components, the former through JDBC and the later
through Trippi (I believe it is the only way).
As I already have a Virtuoso OS instance running with dbpedia loaded, I
think it makes sense to use it for the Fedora triples about the Digital
Objects in the repository so later I can do some nice reasoning using
both graphs.
Details:
https://wiki.duraspace.org/display/FCR30/Installation+and+Configuration+Guide#InstallationandConfigurationGuide-OtherDatabases
https://wiki.duraspace.org/display/FCR30/Resource+Index#ResourceIndex-Configuration
We will have a look at this API to see how difficult it is to write an
adapter for Virtuoso in it.
Note that we already support Jena and Sesame for Virtuoso, as well as
the possibility to use the SPASQL protocol to embed SPARQL/SPARUL
queries direct inside JDBC statement execution.
See: http://ods.openlinksw.com/dataspace/dav/wiki/Main/VOSRDFDataProviders
http://docs.openlinksw.com/virtuoso/VirtuosoDriverJDBC.html#jdbc3features
Note that Virtuoso also has a full ODBC based driver that can handle
both relational queries and SPARQL queries (using SPARQL) as detailed in:
