I have not discussed it directly with Tracker developers, but it's my
impression that they don't feel that Tracker is ready to support a
SPARQL interface for queries yet.

I'm still puzzled, because personally I feel that using a service is
much easier than having to reinvent serializing, parsing and not least
querying every time you begin a new software project?

The Soprano server has a D-Bus, TCP and unix sockets interface for
querying, and wrapping classes for the D-Bus interface are also

Backend, serializer and parser plugins are developed with the Soprano
