Ontohub is linked data compliant. That is, the raw text of an ontology and the HTML page containing a conceptual overview of the ontology can be accessed with one and the same URL. If you enter the URL into a browser, a nice HTML page will be shown. If you enter the URL into a tool like Protege, Hets or wget, the raw ontology text will be delivered. It is also possible to request an xml or json representation, useful for machine processing.
