style='font-size:10.0pt;font-family:Arial;color:navy'>1) First, RE the issue as
to whether specifying the redirect as the canonical identifier when using a URL
is "correct" under HTTP architecture: I'm not an OpenID editor but I
remember that there was a great deal of discussion around this and there was a
good reason (security as I recall) that the final redirect needed to be treated
as the claimed identifier. I don’t remember exactly what it was. Josh,
David, and Johnny: can you chime in here?<o:p></o:p></span></font></p>

style='font-size:10.0pt;font-family:Arial;color:navy'>2) John and Eddy both
pointed out that whatever the claimed identifier was, it can be “overridden”
by the OP in the response to the RP. In that case, the intermediate redirects
don’t matter.<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 color=navy face=Arial><span
style='font-size:10.0pt;font-family:Arial;color:navy'>3) From a SemWeb
standpoint, I believe the right answer is that ALL the identifiers in the chain
– the original identifier, all redirects, and any “override”
back from the OP – should all be considered synonyms for the identified resource.
In other words, rdf:sameAs statements.<o:p></o:p></span></font></p>

style='font-size:12.0pt'>Some thoughts...<br>
<br>
I own abtractioneer.org. Due to the vagaries of technology not under my
control, I'm forced to actually host content on a subdomain -- <a
href="http://www.abstractioneer.org" moz-do-not-send=true>www.abstractioneer.org</a>
-- while maintaining a (302) redirect from <a href="http://abstractioneer.org"
moz-do-not-send=true>http://abstractioneer.org</a> to <a
href="http://www.abstractioneer.org" moz-do-not-send=true>http://www.abstractioneer.org</a>.
The latter actually has the openid metadata. This will be true for all
Blogger-hosted blogs, so it's not just me. So there's some annoyance
there, I apparently must be known as www. That's not great.<br>
<br>
What about when a page moves? Specifically, on Blogger if you acquire a
custom domain for your blog, your old x.blogger.com page redirects to the new
domain. The idea is to not break links, bookmarks, or other things that depend
on the URLs. So abstractioneer.blogspot.com currently redirects to <a
href="http://www.blogspot.com" moz-do-not-send=true>www.blogspot.com</a>.
But what if I had established an account as abstractioneer.blogspot.com on some
service, do the custom domain thing, and then need to go back and login to that
service? If resolution works as below, I can never authenticate as
abstractioneer.blogspot.com. But if the service remembered the URL I
provided, I could choose, by providing abstractioneer.blogspot.com or
abstractioneer.org to the site depending on the site.<o:p></o:p></span></font></p>

<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3 color=black

Because the OP must return the claimed ID anyway, so what do we care which URL
it gets directed too? If you enter "abstractioneer.org" or
"myid.abstractioneer.org" doesn't really matter if discovery works
correctly, since the claimed ID will return always
"myid.abstractioneer.org". Or do I miss the point here?<o:p></o:p></span></font></p>
