It sounds like at least some of what you're looking to do could be accomplished using WebFinger. See:<div><a href="http://code.google.com/p/webfinger/">http://code.google.com/p/webfinger/</a></div><div><br></div><div>WebFinger would allow you to take an identifier for a user and retrieve an XRD that describes the various services publicly associated with that user.</div>

<br>
I'm investigating the possibility of using OpenID as a way to convey<br>
service information to interested parties. In other words, if a user<br>
logs into a site that would like more specific details on a particular<br>
topic, it could query to get any information providers which are<br>
associated with the user. I imagine using the Attribute Exchange, but<br>
there may be a better solution.<br>
<br>
A very simple example would be if a user logged in to a site that would<br>
like to know the exact location of a user. There could be many<br>
providers of this information, so the site queries for the user's<br>
provider. It finds a provider, and from there is able to query the<br>
provider to find the user's exact location. All this is done without<br>
needing to have the user select their provider from a list and log in to<br>
that provider.<br>
<br>
It seems to me that OpenID would be a good way to do it, although it may<br>
be abusing the Attribute Exchange - especially as more types of services<br>
emerge.<br>
<br>
What are your thoughts? Is this in-line with the goals of OpenID? Is<br>
there anything else you would recommend investigating?<br>
<br>
Thank you.<br>
