RDF Model Browser (http://visualrdf.sourceforge.net) is a software
platform for interactive visualization of RDF models. It is intended to
give comprehensive experience with the model using multiple interactive
views. Several views are implemented with this release. 

The cornerstone is Resource-Property-Resource Tree view. Unlike many
other graph visualization tools, it represents RDF model graph as a tree.
Since graphs are fundamentally different from trees some nodes of the
model appear in the tree more than once. A simple layout algorithm is
used for user friendly graph to tree mapping. Full view of a resource
including all its literals is available through Resource view. This view
provides simple HTML visualization of a single resource or a property. In
RDF a property is also a resource.

A filter may be applied to Resource-Property-Resource Tree view to screen
out properties irrelevant to user. If user wants to focus on a single
property the view becomes Resource Tree view.

Both tree views support inverted view where the tree hierarchy is
composed by object rather than by subject. This allows for convenient
representation of models which focus on categorization of
objects.Combined with interactive browsing and property selection the
choice of forward and inverse hierarchical visualizations gives user a
powerful tool for model comprehension. A model can be viewed in a variety
of ways and the user may select appropriate visualizations for different
parts of the model. 

The software is implemented as Java Servlets 2.3 web application. This
allows for easy deployment and integration with other applications. It
has been tested with Apache Tomcat and should be compatible with any
other J2EE Servlet version 2.3 container. 

The software is available under GPL.
