OWL-Sight is an lightweight web-based ontology browser. Our web browser can only understand HTML, so we can’t use them to browse Semantic Web. OWL-sight is an interesting try. Just like protege, it lists the trees of classes and properties, and the releationship between them. But it’s just a browser, you can not use it to edit the ontology.
