The tracker-store is a desktop service that offers the application developer a query capability against data that it stores. The data that it stores must be strictly defined by a schema (which is what in RDF is called an ontology). The schemas that we ship by default are the Nepomuk ones. The query language is SPARQL. The service provides the opportunity to the application developer to store. The application developer uses the an extension to SPARQL, SPARQL Update, which we support too. The communication between application and tracker-store happens over DBus. Nepomuk's ontologies: http://www.semanticdesktop.org/ontologies/ SPARQL: http://www.w3.org/TR/rdf-sparql-query/ SPARQL Update: http://jena.hpl.hp.com/~afs/SPARQL-Update.html RDF: http://www.w3.org/RDF/ Let me know if that was a helpful description for you.
