Jena

Search RDF data with SPARQL: SPARQL and the Jena Toolkit open up the semantic Web. As more data is being stored in RDF formats like RSS, a need has arisen for a simple way to locate specific information. SPARQL, a powerful new query language fills that space, making it easy to find the data you need in the RDF haystack. Take a tour of SPARQL’s features and learn how to use SPARQL queries from your own Java™ applications with the Jena Semantic Web Toolkit.
