Apache Jena is an open source Semantic Web framework for the Java by HP Labs (until October 2009), then Apache Software Foundation. It provides an API to extract data from and write to RDF graphs. The graphs are represented as an abstract "model". A model can be sourced with data from files, databases, URLs or a combination of these. A Model can also be queried through SPARQL 1.1. Jena is similar to RDF4J (formerly OpenRDF Sesame) though, unlike RDF4J, Jena provides support for Web Ontology Language (OWL). The framework has various internal reasoners can be set up to work in Jena.

Jena supports serialisation of RDF graphs to:

• a RDF database
• a relational database
• RDF/XML
• Turtle
• Notation 3
