Hi all,
I'll start by a list of points that could be standardized (open questions).
First, on the authentication part:
1. Standardizing the representation format: RDF/XML, RDFa, N3?
We do need a common format that representation consumers must be able
to understand and that representation publishers must produce.
We've had issues with the libraries we've used. I think it's fair to say
that existing RDF libraries can generally accept RDF/XML more often or
better than they accept RDFa or N3.
Bruno,
Data representation has to be negotiable.
For sake of removing content negotiation requirement we should have
defaults (or example/suggested representations) such as; HTML+RDFa,
N3/Turtle, and RDF/XML.
But we shouldn't bind the protocol to any of the above.
I Don't have issues or strong views re. the other items :-)

To me, some of the interesting questions are:
- Where do the use cases for the two protocols overlap?
The notion of global identifiers.
- Where do the use cases *not* overlap?
- Attribute exchange was retrofitted into OpenID, whereas it was built
into FOAF+SSL from the start, due to the RESTful/linked-data nature.
- FOAF+SSL makes use of public key cryptography, which we could use to
enhance a number of security aspects of identity and trust management.
In particular, we could have WebID consumers (the websites that would
let you log on with a WebID) obtain the public key itself and use a
higher level of assertion regarding to the person holding the private key.
- What are the benefits of using one over the other in the cases
where they overlap?
- Obtaining information about a WebID can benefit from the ontologies
and the uniform interface of the web (discovery by dereferencing).
Best wishes,
Bruno.
