IsaViz is a visual environment for browsing and authoring Resource Description Framework (RDF) models represented as graphs. Since version 2.0, IsaViz can render RDF graphs using GSS (Graph Stylesheets), a stylesheet language derived from CSS and SVG for styling RDF models represented as node-link diagrams. In addition to the Sesame 2.0 implementation of FSL, there is now a Sesame 1.2.2 implementation from Ryan Lee from project Simile.
Here are some key features of "IsaViz":
a 2.5D user interface allowing smooth zooming and navigation in the graph
creation and editing of graphs by drawing ellipses, boxes and arcs
RDF/XML, Notation 3 and N-Triple import
RDF/XML, Notation 3 and N-Triple export, but also SVG and PNG export
Requirements:
You will also need to download graphviz/dot for your specific platform (version 1.8.9 or later is mandatory if you are installing IsaViz 2). Note: some instances of version 1.10.0 had a bug that produced incomplete SVG files, but it has been corrected in subsequent releases (newer versions can be obtained on the graphviz.org site).
Finally, as IsaViz is implemented in Java, it requires a JVM (Java Virtual Machine) 1.3.0 or later (1.4.0 or later strongly recommended - see Known problems) since the GUI makes extensive use of Java2D which featured poor performances in JVM 1.2.x. The latest JVM from Sun can be downloaded at http://java.sun.com/j2se/1.4/
