Java – Build Your Semantic Web Application using Jena

In my previous articles, I talked about GATE, Protégé, Crunch and Lucene. I used all these tools together with Jena to build a semantic web application.

If you have no idea what semantic web is, here is a good introduction. Tim Berners-Lee originally expressed the vision of the semantic web as follows:

I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A “Semantic Web”, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize.

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:

  • Reading and writing RDF in RDF/XML, N3 and N-Triples
  • An OWL API
  • In-memory and persistent storage
  • SPARQL query engine

So far I only described the components that I used in my application. In future articles I will tell you how I put all the pieces together to build my semantic web application.
