1 Graph Visualisation
RDF Gravity defines a visualization package on top of the JUNG Graph API.
For graph layout, it uses the layout algorithms directly supported by the Jung API.
2 Global & Local Filters
The tool allows a user to specify Global and Local filters to have specific views on the graph.
The above functionality allows having customizable graph views on a complex graph structure.
3 Full Text Search
RDF Gravity provides a full text search over concepts, properties and instances specified in a RDF file.
4 Visualising Multiple RDF Files
RDF Gravity allows a user to view multiple graph structures contained in multiple RDF files through a single view.
