HP has released a new version of Jena, its open source Semantic Web toolkit used by enterprises and people around the world to create applications that share, process and integrate information across the World Wide Web.

With more than 17,000 downloads so far, Jena is widely recognised as the most popular toolkit for Semantic Web developers. It is capable of supporting applications as diverse as database integration, knowledge management, news syndication and image annotation.

"Approximately 80 per cent of Semantic Web applications that we have seen at recent major conferences have been based on Jena," said Martin Merry, who manages Semantic Web research at HP Labs Bristol, where Jena was developed.

Jena implements the new RDF and OWL Semantic Web language recommendations announced today by the World Wide Web Consortium (W3C) http://www.w3.org/2004/01/sws-pressrelease. These languages herald a new era of information sharing on the Web.

The purpose of the Semantic Web is to make the Word Wide Web understandable by machines, allowing computers to find and integrate information from diverse sources so that it can be used for different purposes. With the use of Jena, more of the Web's content can be created in a machine-comprehensible form, allowing increasingly intelligent gathering, filtering and processing of knowledge.

"We are proud to be supporting open Web standards with this latest version of the highly successful Jena Semantic Web toolkit, created by one of the leading Semantic Web research groups," said Dick Lampman, HP senior vice-president of Research and Director of HP Labs. "HP is excited by the opportunities that the Semantic Web creates for new information integration services and products."

James Hendler, co-Chair of the W3C Web Ontology Working Group and Director of Semantic Web Technology at the Maryland Information and Network Dynamics (MIND) Laboratory, said: "Jena provides a capable and fully featured support package, backed by HP's reputation as a major player in the computing world. We use Jena heavily in the projects the MIND lab is doing with industrial and government partners. I salute both HP's support for OWL and its decision to release Jena as an open source product."

"The idea behind Jena is to make it easy for developers to try out the Semantic Web," said Brian McBride, the originator of Jena at HP Labs, and co-chair of the W3C's RDFCore working group. "Jena is a free, well-engineered, standards-conformant toolkit. The active and growing community of Jena users, developing a wide range of applications including photo annotation, enterprise knowledge management and data integration, indicate that it is succeeding.
