even that isn't required to get the same result, the presence of any 
token in a profile that you can prove the agent owns will do.

in all use-cases? I of course agree that having some kind of profile 
of information is most useful, but it's not a requirement, and isn't 
needed for all use cases is it?

which file? all we need is a token to be returned via whatever the 
dereferencing process is (whether that's public key from HTTP GET or a 
string in a header returned from HTTP+TLS or many other things).

or, that could be a useful feature, only allow auth from agents you 
can auth yourself - four party.

FOAF+SSL != WebID, if it is then why are any of us here? just call it 
a standard or a spec and be done with it. WebID is what we'll end up 
with at the end of this process.

when did we decide that RDF is returned?

Why not? we've had a proof of concept with FOAF+SSL, we roughly know 
the end result we want (auth for client agents, maybe for any agent 
including server), we have a group of specialists here, we can easily 
put together a list of all the different approaches then weigh them up 
and discuss.

If this is just to put FOAF+SSL, as is, through to rec with a new name 
of "webid" then I can't see there's much need for any of us to be here.

WebID (as in, a potential Web Identity solution) stands at the 
convergence point of almost every web related technology, group, 
specification and implementer currently existing, and it's the XGs 
purpose to identify how as many of those technologies as possible can 
work together to create an identity solution that's usable by the web 
population, to identify the constraints needed for any future protocol 
to work, and to help the related sectors towards the convergence point 
with a shared vision in mind.

I'm not saying the end specification won't be just like, or even the 
same as FOAF+SSL (although I'm quite sure it will differ in some 
aspects), what I am saying is that I believe it's critical to focus 
the group suitably, to stop classing the "WebID Protocol" spec that's 
there as WebID protocol (I'd be happy to see it removed or renamed to 
FOAF+SSL again), and for us all to leverage the skills and knowledge 
in the group to get from where we are now to full Web Identity (with 
related protocol specified and ready for standardization).

Best,

Nathan
