OpenID Exchange

[Recordon, David]

Awesome, glad to see this!  Would be great as Johannes said to see some
flow examples and how you'd see it integrate to do something like
exchange profile data or post a photo on your blog.  Would love to see
this formalized and happy to help however I can!

I have made an early draft of a spec called OpenID Exchange on the wiki:
     <http://openid.net/wiki/index.php/OpenID_Exchange_1.0>

The goal of this protocol is to allow user-accompanied HTTP requests. 
"user-accompanied" means that a consumer makes a request to a service on
behalf of a user and the user reviews and approves the request.

Example applications of this include:
  * Zooomr posting photos into your blog with your one-time approval,
without disclosing your login credentials. [1]
  * Fetching of user profile information.
  * Social networking friendship handshakes. [2]

The protocol should, in theory, be able to act as a transport for any
HTTP-based protocol such as SOAP and AtomAPI, as well as for simple GET
requests. The protocol for "post in my blog" could, for example, just be
an AtomAPI POST request made over OpenID Exchange.

This is still work-in-progress. The spec needs lots of refinement and at
some point I'll have to make a demo or two.

[1] You can still see the results of the demo of my earlier version
    of this on LiveJournal, albeit without the pictures:
