               Jena RDF API and toolkit - release 1.2

Jena is a java API for manipulating RDF models. Its features include:

  o statement centric methods for manipulating an RDF model as a set of
    RDF triples
  o resource centric methods for manipulating an RDF model as a set of
    resources with properties
  o cascading method calls for more convenient programming
  o built in support for RDF containers - bag, alt and seq
  o integrated parsers (ARP and David Megginson's RDFFilter)

This latest release of the jena toolkit integrates a number of new

  o new ARP parser compliant with latest working group recommendations
  o integrated query language (RDQL)
  o support for storing DAML ontologies in a model
  o persistent storage module based on Berkeley DB
  o open architecture supporting other storage implementations

The current release, 1.2.0, is a preview release. We hope it as stable
and functional as jena always has been and should be backward
compatible with previous releases. In the next release we would like
to make various changes, such as cleaning up some features of the API
and shortening the package names, which will require changes to
existing code. Ideally we'd like to make all such changes in one go to
minimise the number of times people have to tweak their client code.
Hence we are putting out this preview release now. Any suggestions you
have for changes to the API - now is a good time to make them! Send
them to the discussion list at: http://groups.yahoo.com/group/jena-dev
