Apache Jena can be utilized to create and run semantic Web applications, linked-data apps, Web-based tools, various types of websites, and even and modern Web servers.
Jena is a collection of tools ranging from an RDF API, to a TDB persistent data store, and up to a SPARQL-compliant engine.
On top of these there's support for the Web Ontology Language (also known as OWL) and a basic inference API.
Most of the Jena framework revolves around RDF, so you'd better be comfortable with the notion of working with it.
Usage instructions and in-depth documentation is included with the download package.
