Apache Jena

Apache Jena is a Java framework for building Semantic Web and Linked Data applications.

ARQ is a query engine that supports SPARQL.

TDB Engine: seems to be an RDF store.

tdbloader (and tdbloader2 on Unix only?) is a bulk loader for TDB. After loading, data should be able to be queried with tdbquery.

./tdbquery --loc /path/to/database 'select * where { ?s ?p ?o }'
