Thanks for the link, this looks like a useful tool! I am installing it right now (and reading the manual).

However, I was mainly thinking about RDF browsers that can be accessed through a common web browser. So far all of the RDF browsers we have looked into have been integrated into the normal server / webbrowser architecture, so I was implying that. COE requires an installation.

Oh, I think you got me wrong here. I did not mean OWL without any classes, but with a certain ratio of classes to individuals. I prefer ontologies that have a certain set of classes (say 20 to 100) that act as a schema, and where most of the 'actual data' is expressed as individuals and the basic schema stays untouched. Still, you can do a lot of reasoning with such ontologies.
