OpenID 1.1 RDF Schema [was: RE: Tiny RDF Schema at openid.net?]
Hi David, I've had another look at the 1.1 spec, tweaked the schema, and incorporated some feedback I received from the SemWeb IG (SWIG). The new schema also includes identifier which - although just a single property - allows RDFers to easily connect OpenID with the rest of the RDF world. The latter has been discussed quite a bit recently, esp. the FOAF folks are looking forward to a FOAF2OpenID connector. I *think* the schema is ready to go now, it would be really great to have it served from openid.net. I'll send a schema draft for openid2 in a separate mail. Anything else I can do?

OpenID 2 RDF Schema Draft [was: RE: Tiny RDF Schema at openid.net?]
Hi, here is a first RDF Schema draft for OpenID 2.0 authentication. *If* the provider/local_id terms are equivalent to server/delegate, we could add some additional OWL bits to explicitly state this. Using OWL's equivalence axioms would mean that every v2-OP is also a v1-IdP and vice-versa, not sure if that's the case. There are axioms for non-bi-directional relations (e.g. if any v2-OP can handle v1 auth, but not necessarily the other way round). It could make sense to add more terms (e.g. the endpoint URL etc.) to a v2 RDF Schema, I'd have to read the spec more closely before, though. Don't know if I mentioned it already, it'd also be possible to directly embed the RDF Schema in the HTML version via eRDF[1]. This approach would lead to less pretty term URIs (document URL + # + HTML id), but removes the need to maintain two separate documents (in case that is an issue).
