I don’t know what URI format they’ll use, but let’s say it is
<a href="https://myopenid.com/joseph">https://myopenid.com/joseph</a>. Or,
perhaps it’s <a href="https://joseph.myopenid.com">https://joseph.myopenid.com</a>.
Whatever the format, there is always a user component to it. So, it
would be quite simply to take the user component and put it into an e-mail ID
style like <a href="mailto:joseph@myopenid.com">joseph@myopenid.com</a>.
This does not necessarily mean you have an e-mail address, but it <i>could be</i>
an e-mail address.<o:p></o:p></span></p>

color:#1F497D'>The conversion from that form to a URI form is easily achieved via
NAPTR records similar to the one I show below. So, before any XRDS query
is performed, the RP would see if the ID provided is an e-mail-style ID.
If so, query for the NAPTR record and then perform the conversion from the
e-mail-style to a URL. From there, it all works the same. It’s
just a “make it simple” enhancement that requires no changes to the
core Open ID specs.<o:p></o:p></span></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I
share many of same opinions. If OpenID is going to be practically usable
by the average person, we cannot require the person to remember some very
complex identifier. When I signed up for Yahoo’s OpenID service, it
presented me with a hideously ugly URL that looked similar to a base64-encoded
string. I could not begin to tell you what it was. Fortunately,
Yahoo allowed me to define my own, friendlier name. Still, the ID is not
one that the average user will remember or get right.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>While
the e-mail address does not have to be the one’s ID, it can certainly
serve as an alias. Suppose, for example, that the DNS records at Yahoo
contained the following entry:<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>This
would allow a Relaying Party to accept an e-mail address and perform a simple
transformation to get the “real” URL identifier. Of course,
this does not mean that the existing URL or XRI identifiers are invalid, nor
does it mean that the “email address” has to be a real e-mail
address. But, this form would certainly be far simpler for most people to
deal use.<o:p></o:p></p>
