Since everything is RDF data, and\neverything is identified with a URI, this \"foreign\" RDF data might be\nconceptually dealt with as just another graph:\nTracker provides means to make RDF triple stores publicly available as SPARQL\nendpoints both via HTTP(S) and D-Bus protocols. By default, triple stores\nare not exported as endpoints, and are considered private to a process.\n"});
