incubator.apache.org/jena/


Welcome to the Apache Jena project! Jena is a Java framework for building Semantic Web applications. Jena provides a collection of tools and Java libraries to help you to develop semantic web and linked-data apps, tools and servers.
The Jena Framework includes:
  • an API for reading, processing and writing RDF data in XML, N-triples and Turtle formats;
  • an ontology API for handling OWL and RDFS ontologies;
  • a rule-based inference engine for reasoning with RDF and OWL data sources;
  • stores to allow large numbers of RDF triples to be efficiently stored on disk;
  • a query engine compliant with the latest SPARQL specification
  • servers to allow RDF data to be published to other applications using a variety of protocols, including SPARQL
