Soprano is a software library that provides an object-oriented C++/Qt4 framework for RDF data. Soprano was created as a sub project under the NEPOMUK project and forms a part of the semantic desktop in KDE Software Compilation 4. Soprano functions as a repository to store information generated by the NEPOMUK server (like ratings, tags or comments), which will then be indexed by Strigi for better search results.

Soprano comes with support for redland and Sesame2 backends for actually storing and querying the RDF data.

Features

• Simple plugin design, with 5 different classes of plugins
• Server/client architecture which allows to run an RDF storage remotely. Interfaces for communication over TCP, Unix sockets, and D-Bus are provided
• Fully documented API using Doxygen
• CLucene index which provides a full-text query index
