From the official site of Jena:Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine.
Jena is open source and grown out of work with the HP Labs Semantic Web Programme.
The Jena Framework includes:
- A RDF API
- Reading and writing RDF in RDF/XML, N3 and N-Triples
- An OWL API
- In-memory and persistent storage
- SPARQL query engine
Besides, Jena's documentation in sourceforge I found very useful this article by IBM for an introduction on how Jena works.
Another useful link, is this youtube video, which gives detailed instructions on using Jena in Netbeans. I don't know what language is this, but I understood what to do. :)
