RE: [xri] PLEASE REVIEW: WD11 Section 8 (Yadis) proposed text

["Drummond Reed" <drummond.reed@cordance.net>]

Laurie,

You bring up a good point: the whole evolution of Yadis has caused a lot of
confusion about "What is Yadis?" vs. "What is XRI resolution?"

To be honest, I don't think folks outside of the XRI TC have a clear picture
of the difference between Yadis and XRI resolution. The purpose of the
original Yadis spec was simply to define a process for discovering an XRDS
document from an HTTP(S) URI. The Yadis 1.0 spec was then referenced from
the OpenID Authentication 1.1 spec.

The goal now as I understand it from the OpenID editors is for the OpenID
Authentication 2.0 spec to be able to reference:

1) Section 3 of the XRI Resolution 2.0 spec for XRDS document definition.

2) Section 8 of the XRI Resolution 2.0 spec for discovery of an XRDS
document from an HTTP(S) URI ("the process formerly known as Yadis").

I think it's a good idea if the OpenID Authentication 2.0 spec makes clear
the difference between doing XRI resolution (starting from an XRI of course)
and discovery of an XRDS document starting from an HTTP(S) URI, and I agree
we should make that request of the OpenID Authentication 2.0 editors.

Do you have any other feedback on the
http://wiki.oasis-open.org/xri/XriCd02/XrdsDiscoveryFromHttpUris page?

I know we've already discussed this in the last couple of weeks, but it 
seems that the term "Yadis discovery" is still causing a lot of 
confusion (at least to me).

Drummond, is the discovery text in the OpenID spec going to be edited to 
more clearly explain the difference between "Yadis" discovery and XRI 
resolution.

To be honest, I was under the impression for a long time (until last 
last fall at least) that Yadis discovery was the more general term for 
both URIs and XRIs. Perhaps it might also make sense to make this 
clearer in the Yadis spec as well? If this has already been changed, 
please ignore my comments.
