we are proud to announce a first public release of TRIPLE.

TRIPLE is a general RDF query, inference, and transformation
language which allows various semantics of Semantic Web languages
to be defined, either directly with TRIPLE rules, or by
accessing external inference engines (like a DL classifier).

One goal of TRIPLE is to have a language for data integration
which requires one inference process to understand and process
the semantics of several data sources which are expressed
in different (Semantic Web) languages like RDF Schema, DAML+OIL,
OWL, UML, Topic Maps, etc.

TRIPLE also contains a standalone DAML+OIL implementation
with the following features:

- parses DAML+OIL ontologies with Jena
- output in various syntaxes (LISP, XML for FaCT DTD; others
  can easily be added)
- external DL classifier can be automatically invoked
  (at the moment, RACER; support for FaCT will follow)
- output from DL classifier (taxonomy only) can be returned
  in various formats:
  DAML, LISP, XML, DOT (for visualization with GraphViz)

TRIPLE is joint work with Stefan Decker and can be downloaded
(for Linux and Windows) from:
