OpenID V.Next - Some Views to Consider

Santosh,

 

The subject of paulej at packetizer.com is what?

If that can be assumed to be acct:paulej at packetizer.com, then when WebFinger
is employed, the Subject of the XRD document is acct:paulej at packetizer.com.
That's not what I want.

 

Inside the XRD document should be a link like this:

<Link rel="openid" href="http://openid.packetizer.com/paulej"/>

 

The link relation value is still subject to debate, but that's what I think
we should use to identify the claimed ID.

 

Paul

I will vote for the Subject of the XRD to be the claimed_id. It only seems
natural, and clean to do that.

So if openID supports LRDD then normalization rules for Acct: and other URI
schemes could be specified so that they to can be resolved to a XRD.

 

The question will be for the core protocol what to use as the claimed_id.   

 

There are three schools of thought.

1 The normalized input identifier

2 The Subject of the XRD

3 The claimed_id that the OP returns.

 

There are arguments to be made for all three.

 

I expect this to be addressed in the WG.

Starting a new thread here based on an earlier one quoted below.

 

Let us reconsider the definition of OpenID for V.next. I would like to see a
new definition for OpenID.

 

"An OpenID is Any Valid URI that can be resolved to it's Descriptor".

 

Now let me give a little explanation on the above, with a few points.

1) Existing OpenID's version 1 and 2 are compatible with the above
definition. (http(s) OpenId's version 1 and 2 do resolve to their
descriptor's)

2) Email like identifiers are compatible with the above definition with the
webfinger protocol, and ofcourse resolve to their descriptor's.

 

Now any other future protocol that can make its URI resolvable to a
descriptor, will also be a Valid OpenID. Let me give an example.

 

According to the above definition we can make "tag URI's" valid OpenID's, as
long as we have a protocol to resolve this URI to its's descriptor.

 
tag:user at example.com <mailto:tag%3Auser at example.com> ,2007-11-02:Tag_URI

 

Now as far as I am concerned tag URI's are even better as OpenID's, because
they are unique over space and time.

 

Webfinger support for tag URI's anyone? :-)

Santosh,

 

Why not store the claimed ID in the webfinger (LRDD) XRD document?

 

The objective, I would hope, is to make it easier to log into web sites.
Email-style identifiers make that easier, but the system does not have to be
built around those.

 

So, I sign up with a service provider.  Let's just use my own site as an
example.  I am assigned an email address paulej at packetizer.com.  Behind the
scenes, I am also assign an OpenID ID http://openid.packetizer.com/paulej.
Now, when I visit a web site, I can type 'paulej at packetizer.com' and the
site can perform a webfinger query to discovery by OpenID ID.  We would
define a link relation (something we've talked about before) that represents
openid.  It could be http://openid.net/identity or it could be simply
"openid" (since link relations need not be URIs).  Looking at the href of
the "openid" link relation, one would find my OpenID URI
http://openid.packetizer.com/paulej.

 

Now, should I wish to have a different email provider than my openid
provider, that's fine: I could change the record associated with the openid
link relation to contain a different OpenID identifier.  Alternatively, I
could just get an account at someopenidop.com <http://someopenidop.com/>
and they might assign an e-mail style address like paulej at someopenidop.com
and perform the Webfinger resolution behind the scenes.

 

Anyway, issue this request:

$ curl http://www.packetizer.com/lrdd/?uri=acct:paulej@packetizer.com

 

You'll see the link relation for my claimed ID:

<Link rel="http://openid.net/identity"

      href="http://openid.packetizer.com/paulej"/>

 

It does introduce another protocol, but I think these play nicely together.
The real identity would remain the URL that OpenID uses today.  The email
identifier would just be an alias for it.

Adding support for email-style addresses is something I like, but something
that can be provided via webfinger.  Thus, no change to the base protocol.

 

 

I beg to disagree here. I think the base protocol needs to address the issue
of email like identifiers. I would like to see that email like identifiers
are valid OpenID claimed id's.

So something like acct:example @ example.com <http://example.com/>  should
be a valid OpenID claimed_id.

 

Also this discussion should not be in this thread (about attributes) and
maybe someone could start a new thread on this subject.

 

Thanks

Santosh
