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).
Cheers so far,
Ben

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?
Cheers,
Ben

To provide a little bit of background for my initial mail: My objective
is to generate some RDF triples from the OpenID hooks encoded in HTML.
The common practise these days is to create a simple custom transformation
which does the job ("GRDDLing"). However, the existing OpenID format
instructions (link+rel+href) are already compatible with a format
called eRDF[1], which follows the DC guidelines. We could directly
re-use eRDF parsers and transformers. What's missing is a namespace
URI for the "openid" prefix in HTML. (It would actually be possibe
to use eRDF to encode the RDF Schema information directly in the
HTML version of the OpenID specs as well. There is no need for a
separate schema file).
With regard to general RDFS/OWL versioning, there are different options.
If v1, v1.1, and v2 form *one* evolving spec with mostly overlapping
terms (i.e. the semantics -and maybe even the naming- of many v2 terms
is identical to those from pior versions), the trend seems to be to
stick to a single namespace URI and to use OWL constructs to indicate
deprecated terms before they are removed from the spec. If v2 is really
different from v1 or you want a clean start, the specs should be in
two schema files with different namespace URIs, maybe with links from
the new one to the old (there are things like "sameAs" and
"equivalentProperty" in OWL).
Different namespaces also means that the HTML hook prefixes should
reflect that, i.e. "openid.server openid2.provider" is fine,
"openid.server openid.provider" would not allow the definition of
different namespaces URIs for the two terms in eRDF. So, with a new
prefix (openid2), there should probably also be a new spec file.
My suggestion would be to create two files, with the v2 one linking
to the v1 one via owl:equivalentProperty (if the new terms are
equivalent, that is)
Ugh, I hope that was more helpful than confusing..

I'm not an RDF/OWL expert, though that looks reasonable to me. How do
we deal with Auth 1.x which uses openid.server and openid.delegate
versus Auth 2.0 which uses openid2.provider and openid2.local_id?
