Description:
Current work on this issue stems from June 2009 a discussion of
Web Application State Management
http://www.w3.org/2001/tag/2009/06/23-minutes.html#item04

It was closed Jan 2007:

The use of Metadata in URIs (2 January 2007)
http://www.w3.org/2001/tag/doc/metaDataInURI-31.html

"Abstract

This finding addresses several questions regarding Uniform Resource Identifiers (URIs). Specifically, what information about a resource can or should be embedded in its URI? What metadata can be reliably determined from a URI, and in what circumstances is it appropriate to rely on the correctness of such information? In what circumstances is it appropriate to use information from a URI as a hint as to the nature of a resource or its representations? Simple examples are used to explain the tradeoffs involved in employing such metadata in URIs."

The TAG approved this finding at its 11 December 2006 face to face meeting.

"There should be a uniform way to declare version history of web resources (recommended by W3C)?, and more importantly

There should be a "clean", uniform way to refer to (and thus access) the metadata of web resources?"

Related notes:

using RAISED to mean: a proposal to re-open is being discussed (if not the substance of the issue itself).

Dan Connolly, 8 Feb 2010, 15:39:26

it seems only OPEN issues show up in tracker's agenda, so please take this as sorta *provisionally* open unless/until the chair accepts a proposal to re-open it.

Dan Connolly, 9 Feb 2010, 19:31:53

moving to Web Apps product per Noah's note on action-412 in

Jonathan Rees, 12 Oct 2010, 17:21:10

The description of this issue says it was reopened to deal with Web application state management. I think the publication of the Web Application State finding is sufficient to merit (re)closing this issue.

Marking PENDING REVIEW.
