JRDF 0.4 Released

JRDF 0.4.0 is now out. The main difference between it and previous versions is that it is for Java 1.5 and above only. Also, Tom's SPARQL query engine is in. There's also bug fixes to do with RDF/XML parsing (mainly to do with feedback from Kowari developers). There's also initial interfaces for graph and relational operations (which may change). The beginnings of an index interface (using the idea of perfect indexes) has begun (org.jrdf.graph.index package). An NTriple grammar has also been added but there's no parser as yet.
