------------------------------------------------------------------ 
6. New Issues.
*	Http Binding of faults (Hugo) 

HTTP Binding of faults, how to serialize, how to relate to status codes,
Hugo has a proposal.


 <http://lists.w3.org/Archives/Public/www-ws-desc/2004Apr/0032.html> 

------------------------------------------------------------------ 
7. Issue 165: Adding HTTPS support [.1]

*	Youenn suggests specific text about https: uris 
*	 See also issue 56 - proposal is to close it - it's a hard thing to
get right
*	.Jacek's "purpose of the binding" text 

Youenn will add text about endpoints to Jacek's text about purpose of
binding.

Youenn proposes that we add a marker that indicates whether https can be
used.

Youenn - default is either http or https, marker can constrain to http or
https.

Sanjiva - adding marker is slippery slope to adding markers for other things
like authentication.

Yaron - where do we express expectations and policies for a service?

Umit - The answer is clear, F&P. 

Sanjiva - shouldn't add anything to the core language for this.

Poll - do we need to have a marker to indicate the use of https?
3 yes, 6 no

Resolved to have no marker in core deliverables, add Jacek's text with
Youenn's addition.

Will leave 165 open pending purpose of binding text

------------------------------------------------------------------ 
8. Issue 64 [.1] Operations as HTTP verbs (Mark Baker) [.2, .3, .4]
*	Jacek's synthesis [.5].
*	Awaiting description from Philippe showing how properties or
extensions can be used to annotate the WSDL with RESTful properties. Ask
Mark for a definitive list of those properties so we can consider how to
associate them with property URIs or namespaces. 
*	Does the current draft [.6] with "method" attribute address this
issue? Not completely, Mark [.7] and DavidO [.8] reply. 

DaveO - 2 issues: additional http methods, web method feature at the
interface and binding level.

Jonathan - gave an example of operations with names "get", "post", that bind
to http verbs.

DaveO - not enough, need a way to indicate for operations that have
different names, which REST operation semantic that have.  (Like Atom).

DaveO - need to treat HTTP as transfer protocol, not just transport.

ACTION: DaveO will come up with concrete proposal.

Do we allow only a fixed set of http verbs or do we allow all, including
extensions?

ACTION: Hugo will look at adding extensions to http proposal to allow
arbitrary http verbs.


------------------------------------------------------------------ 
No discussion on remaining issues

------------------------------------------------------------------ 
New Action Items

ACTION: DaveO will come up with concrete proposal

ACTION: Hugo will look at adding extensions to http proposal to allow
arbitrary http verbs.
