From the website:
RDF Gravity is a tool for visualising RDF/OWL Graphs/ ontologies.
Its main features are:
- Graph Visualization
- Global and Local Filters (enabling specific views on a graph)
- Full text Search
- Generating views from RDQL Queries
- Visualising multiple RDF files
RDF Gravity is implemented by using the JUNG Graph API and Jena semantic web toolkit.
Truly stunning work.
Too bad that RDF will never progress beyond simple indexing to complex and interchangeable indexing.
I say that. So long as Tim Berners-Lee clings to the notion of new names (URLs) as overcoming the problems with old names (anything else), RDF is unlikely to improve.
If an RDF could identify a subject using multiple properties and then inform others of that complex identification, then at least there would be an opportunity to either agree or disagree with an identification.
As it is now, who knows what anyone is identifying with a URL?
Your guess is as good as mine.
So if I were to say that “http://semweb.salzburgresearch.at/apps/rdf-gravity/index.html” is truly stunning work, do I mean the software? The website? Something I saw at the website?
If that sounds trivial, imagine the same situation and the URL is a pointer to a procedure for the coolant system on a nuclear reactor. Not quite so trivial is it?
Best to know what we are talking about in most situations.
