1) XRD 1.0 - LINK HEADER/HOST META/LRDD

	http://tools.ietf.org/html/draft-nottingham-http-link-header
	http://tools.ietf.org/html/draft-nottingham-site-meta 
	http://tools.ietf.org/html/draft-hammer-discovery 

Eran gave a general update on the key developments with these specs:

* The authors of a "Web finger" protocol under development have provided
feedback that host-meta should be in a well-known directory rather than at
the root level. General example:

	example.com/.well-known/host-meta

* Eran also plans to move all the /host-meta extensions, including Link
Patterns, in LRDD into /host-meta itself.

* He plans to demote the importance of the describedBy descriptors and
promoting the importance of rel URIs.

* He's going to add a template that guides users through a set of questions
that will provide guidance about best practices.

* He believes that LRDD will become an IETF "best current practices"
document, which is a formal document type at IETF.


2) XRD 1.0 - STATUS ON WORKING DRAFT 01

Will has produced and posted an initial draft which Eran has briefly looked
at and will do a deeper review before Internet Identity Workshop next week.

Will noted that there are currently a number of hanging references to other
documents RE processing. To the extent that LRDD is a best-practices guide,
Eran suggests copying significant portions of it into XRD so it reads as one
standalone document.

Will also noted that the extensibility model means the libraries he has
written must be modified to retain data from tags they don't know about.

We discussed the overall structure of the spec as three parts:

	1) Discovery Process
	2) XRD Schema
	3) Processing for Service Endpoint Selection

The parts that XRD 1.0 is entirely authoritative for are (2) and (3).

However there are still a number of open issues around (1). This includes
the suggestion that if servers use a well-known directory instead of a
well-known filename, the server may actually be able to serve up an XRD
directly.

We talked about sessions planned for Internet Identity Workshop
(http://www.internetidentityworkshop.com/). 

* Discovery process - Eran
* How to use XRD with OpenID - Dirk

There will be probably be a number more - this promises to be a very busy
IIW.


3) XRI 3.0 - STATUS ON WORKING DRAFT 01

Drummond reported that he is now well into the project and will have a
partial draft (all ABNF, but not all text) posted before IIW.
