Welcome to 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
Apache Jena is an effort undergoing incubation at The Apache Software Foundation (ASF),
sponsored by the Incubator project. Incubation is required of all newly accepted
projects until a further review indicates that the infrastructure, communications, and
decision making process have stabilized in a manner consistent with other successful
ASF projects. While incubation status is not necessarily a reflection of the completeness
or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
