    Jena 1.6.0
    A Java API for manipulating RDF models

    Download: http://www.hpl.hp.com/semweb/download.html
    Jena mailing list: jena-dev@yahoogroups.com

New features in Jena 1.6.0 include:

+ Support for N3 in reading and writing RDF models.

  A new streaming N3 parser provides data input and output in N3.
  The inclusion of N3 as a data format for Jena does not provide a rules
  interpreter - it is just for RDF input and output in N3 format.   

  The Jena N3 Writer is a pretty printer for N3.  It is a multi-pass writer
  that looks at the model first before starting to write N3.  As such, it
  is not tuned to writing huge RDF models such as databases.

  Improvement will be made to the Jena N3 Writer to increase its

+ An RDQL query engine that executes the query on a remote
  Sesame repository [1]

Changes in <jena>/lib

One JAR has been removed (rdffilter.jar) as the original Jena RDF/XML
parser has been deprecated after discussion in jena-dev@yahoogroups.com

There are two new JAR files in the lib directory, one for the antlr 2.7.2a2
runtime used by the N3 parser and one for the Sesame client.
