Virtuoso OntoDriver
As a user, I want to be able to use Virtuoso server as storage. This will, according to documentation, require a custom OntoDriver implementation using either Virtuoso's RDF4J or Jena provider.
The driver should probably allow the user to choose whether the RDF4J or Jena Virtuoso Provider will be used for connection. The other choice is to support only one of the providers for starters.
Note that Virtuoso code (including the providers) is licensed under GPLv2, so the driver, which will probably have to incorporate the provider(s) - as they are not published in Maven - will have to adhere to this license as well.
Relevant sources:
Waiting for OpenLink to publish its RDF4J/Jena provider in Maven. See issue 249 and the corresponding PR 905 for mavenizing the RDF4J provider.
