Soprano (formally known as QRDF) is a library which provides a nice Qt
interface to RDF storage solutions. It has a modular structure which
allows to replace the actual RDF storage implementation used.
Soprano has the following features:
* Full context (i.e. named graph) support
* Plugin structure for extensibility.
* Backend plugins for:
- Redland
- Sesame2
* Parser and serializer plugins for:
- raptor (rdf+xml, turtle, trig, nTriples)
- nQuads
* A server and client lib which allows a simple remote
Soprano server.
* Simple sopranod server application.
* Simple command line tool to perform commands on models in
a Soprano server (sopranocmd)
* Rule-based Forward inference engine.
* Full-text index based on CLucene which indexes all literal
statements (i.e. those statements with a literal object node)
* Hierarchical architecture which allows to stack multiple filter models
on top of an RDF storage.
