Re: [Virtuoso-users] Trippi connector

[Patrick van Kleef]

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:

#InstallationandConfigurationGuide-OtherDatabases

+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.

Note that Virtuoso also has a full ODBC based driver that can handle  
both relational queries and SPARQL queries (using SPARQL) as detailed  
in:
