SPARQL-MM

Extending SPARQL to Multimedia

SPARQL-MM is a multimedia-extension for SPARQL 1.1 implemented for Sesame. By now it supports relation, aggregation and accessor functions for Media Fragments URI 1.0 - and features are constantly extended.

Usage

SPARQL-MM can easily appended to any Sesame Triplestore via Java Class Loader Technology. The package is available on Maven Central.
