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. Best regards, Dima
