Hi,

we implemented a simple tool (FRODO RDFSViz) which
provides a visualization service for ontologies
represented in RDF Schema. It uses the Java RDF API implementation
(Sergey Melnik) and the Graphviz graph drawing program (AT&T and
Lucent Bell Labs).

An online demo (Java servlet) is available at:

	http://www.dfki.uni-kl.de/frodo/RDFSViz/

A downloadable version will soon be made available.

The tool creates simple class diagrams where classes become vertices
and rdfs:subClassOf relations become edges. Optionally, properties
with rdfs:Class-valued domains and ranges are also visualized as
(labeled) edges. Future extensions are planned, e.g., to show properties with
range rdfs:Literal or to support the strawman syntax.

It is quite similar to the Rudolf RDFViz tool (Dan Brickley) which
visualizes general RDF models, but these visualizations are (in our
opinion) not well suited for complex ontologies/RDF schemas.

The FRODO RDFSViz tool was implemented in the FRODO project (A
Framework for Distributed Organizational Memories) at DFKI Kaiserslautern
(German Research Center for Artificial Intelligence).

Comments, bug reports, ideas for improvements etc. are welcome.
