RDF-Gravity (Index Page) Sunil Goyal, Rupert Westenthaler {sgoyal, rwestenthaler}@salzburgresearch.at Salzburg Research, Austria RDF Gravity is a tool for visualising RDF/OWL Graphs/ ontologies.
Its main features are: Graph VisualizationGlobal and Local Filters (enabling specific views on a graph) Full text SearchGenerating views from RDQL QueriesVisualising multiple RDF files RDF Gravity is implemented by using the JUNG Graph API and Jena semantic web toolkit. Figure 1: Screenshot of RDF-Gravity, showing a part of Wine Ontology 1 Graph Visualisation RDF Gravity defines a visualization package on top of the JUNG Graph API.
Configurable renderers for edges and nodes of a graph, including different node shapes and edge decorations etc.A Renderer Factory allowing the configuration of the above node and edge renderers based on the type of an edge or node. For graph layout, it uses the layout algorithms directly supported by the Jung API. 2 Global & Local Filters 3 Full Text Search.

Before downloading, please read the license agreement carefully. Download The demo requires Java Web Start to be installed on your machine You can download Java Web Start from here If you're using RDF Gravity for the first time, please check out the documentation page. Sample RDF files are available at - Some FOAF(Friend of a Friend) files in RDF are available at : 1) 2) OWL files 1)Camera Ontology: 2)Countries: 3)Wine Ontology: 4)Food Ontology: Note: Some ontology files (Wine & Food) might take time to load and have an improper layout after loading. For bigger ontologies, its preferred to clear the graph (display area) after loading, by clicking "Clear Graph" in the Local Filter Panel and then display the relevant parts via searching for interested resources.
License Statement: RDF-Gravity (documentation) Sunil Goyal, Rupert Westenthaler {sgoyal, rwestenthaler}@salzburgresearch.at Salzburg Research, Austria 1 Introduction 1.1 Overview RDF GRAph VIsualization Tool (RDF Gravity) is a tool for visualizing directed graphs built in RDF and OWL.
The tool provides a simple yet powerful visualization of RDF graph structures and the ability to filter out and visualize specific parts or fragments of RDF Graphs. Figure 1: A part of Wine Ontology showing different Wines in RDF Gravity Its main features are: Graph Visualization (Renderers/ Zoom/ Selection)Filters (Global, Local, Namespace, Instance level) enabling specific views on a graph. 1.2 Installation RDF Gravity is built in Java and requires JVM1.3 or higher. 2 General Notations The table below provides the notations used the RDF Gravity tool for denoting RDF resources and properties. Table 1: Denotes notations used by the RDF Gravity Tool. 3 Graph Visualization The tool allows user to visualize RDF graphs and navigate through them easily. 3.2 Zoom.
