Jenabean

Jenabean binds a Java object model to Jena. It is annotation based and does not place any interface or extension requirements on your java object model. By default jenabean uses typical java bean conventions to derive RDF property URIs, for example, the java bean property “name” would become RDF property “hasName”. jenabean allows for explicit binding between an object property and a particular RDF property.
