Hi Andrew,<br>
<br>
If you just want to read public information that's available for an
OpenID, then have you considered embedding microformatted data (like an
hCard) onto the page referenced by the OpenID? For instance, if the
OpenID was someone's Profile Page, the RP could just read the hCard on
the page to extract the public information for that OpenID.<br>
<br>
You could do this today with OpenIDs from MyOpenID and Flickr.<br>

type="cite">Attribute Exchange seems to rely on being part of an
authentication message as opposed to being able to work when in
OpenID's no-authentication extension mode. I get this from section <a
moz-do-not-send="true"
href="http://openid.net/specs/openid-attribute-exchange-1_0.html#identifier-definition">3.1</a>
of the AX spec getting the subject identifier from the authentication
part of the message.<br>
<br>
My suggestion would be that if we can, in a subsequent version of AX,
allow AX to stand alone without OpenID having to send an authentication
request at the same time, then given an OpenID URL by itself, people
can query against it. Now, most information would probably need to be
kept private, but perhaps some information, like contact information,
can be made available provided the requestor respond to a CAPTCHA or
something like that. That would be up to the individual OPs and their
users of course as to which information to be willing to disseminate,
but the power of the feature is there.<br>
<br>
What do you think?<br clear="all">
