From my little experience of Web ontologies, and according to a recent study on the use of OWL terms online [1], very very few. But all the OWL-2-specific features are showing up very little yet, in part because they are not well known (I still see often citations of the OWL 1 spec when referring to the standard Web Ontology Language) and in part because the new features are more complicated to use. People tend to use more what can be expressed with a single triple. There is also, I believe, a concern about whether this will interoperate with other people's applications, since not all semweb apps implement an OWL 2 processor. [1] B. Glimm, A. Hogan, M.
