[Bug 317271] Re: nepomukservicestub causes crash in Soprano::Redland backend

[Sergei Andreev]

And how about this new backend:
"A new backend for Soprano which could finally let us drop the sesame2 backend which needs a JVM.

Today I committed the new Virtuoso Soprano backend. Virtuoso is a
powerful SQL/RDF DB server created by OpenLink Software. OpenLink
provides an open-source version of their database server released under
the GPL. The official description from their homepage reads:

    At core, Virtuoso is a high-performance object-relational SQL database. As a database, it provides transactions, a smart SQL compiler, powerful stored-procedure language with optional Java and .Net server-side hosting, hot backup, SQL-99 support and more. It has all major data-access interfaces, such as ODBC, JDBC, ADO .Net and OLE/DB.
    [...]
    OpenLink Virtuoso supports SPARQL embedded into SQL for querying RDF data stored in Virtuoso’s database. SPARQL benefits from low-level support in the engine itself, such as SPARQL-aware type-casting rules and a dedicated IRI data type. This is the newest and fastest developing area in Virtuoso."

[...]
Virtuoso not only frees us from the shackles of the java dependency. It also provides a bunch of features that Sesame2 does not. Most importantly Virtuoso features full text indexing which can be used within SPARQL queries
[...]
The nice guys at OpenLink were very open to the idea of using their server in KDE. With the release of Virtuoso 5.0.10 they introduced a new lite mode which trims the server down to our needs. The memory usage goes down to a minimum: IMHO roughly 80M is acceptable. (Especially since the JVM easily goes up to 10 times that value!) That in combination with disabling pretty much all features except for SPARQL we have a decent desktop DB solution.
