Dear Advisory Committee Representative,

I am pleased to announce that Media Fragments URI 1.0 is a W3C Candidate 

The approval and publication are in response to this transition request:

There were no Formal Objections. This specification had been changed in 
response to comments received during the two previous Last Call periods. 
The Status section contains links to the changes between the first and 
second Last Calls and between the second Last Call and the current Document.

The Working Group has adopted a public test suite for the User Agents 
and has produced an implementation report for this specification; see 
the transition request for details.

This Call for Implementations follows section 7.4.3 of the W3C Process 

Thank you,

For Tim Berners-Lee, Director,
Philippe Le Hégaret, Interaction Domain Lead, and
Yves Lafon, Media Fragments Working Group Team Contact;
Ian Jacobs, Head of W3C Communications

This document describes the Media Fragments 1.0 specification. It 
specifies the syntax for constructing media fragment URIs and explains 
how to handle them when used over the HTTP protocol. The syntax is based 
on the specification of particular name-value pairs that can be used in 
URI fragment and URI query requests to restrict a media resource to a 
certain fragment. The Media Fragment WG has no authority to update 
registries of all targeted media types. We recommend media type owners 
to harmonize their existing schemes with the ones proposed in this 
document and update or add the fragment semantics specification to their 
media type registration.

Status of this Document [non-boilerplate]

This is the Candidate Recommendation of the Media Fragments URI 1.0 
specification. It has been produced by the Media Fragments Working 
Group, which is part of the W3C Video on the Web Activity. The Working 
Group expects to advance this specification to Recommendation Status.

The W3C Membership and other interested parties are invited to review 
this Candidate Recommendation document and send comments through 08 
December 2011. Please send comments about this document to 
public-media-fragment@w3.org mailing list (public archive). Use "[CR 
Media Fragment]" in the subject line of your email. We expect that 
sufficient feedback to determine its future will have been received by 
08 December 2011. This specification will remain a Candidate 
Recommendation until at least 20 November 2011.

The Media Fragments Working Group will advance this specification to 
Proposed Recommendation when the following exit criteria have been met:

	• Sufficient reports of implementation experience have been gathered to 
demonstrate that the Media Fragments URI syntax and processing features 
are implementable and are interpreted in a consistent manner. To do so, 
the Working Group will insure that all features have been implemented at 
least twice in an interoperable way.
	• The implementations have been developed independently.
	• The Working Group has adopted a public test suite for the User Agents 
and has produced an implementation report for this specification.
The Implementation results are publicly released and are intended solely 
to be used as proof of Media Fragments URI implementability. It is only 
a snap shot of the actual implementation behaviors at one moment of 
time, as these implementations may not be immediately available to the 
public. The interoperability data is not intended to be used for 
assessing or grading the performance of any individual implementation. 
Any feedback on implementation and use of this specification would be 
very welcome. To the extent possible, please provide a separate email 
message for each distinct comment.

This Candidate Recommendation version of the Media Fragments URI 1.0 
specification incorporates requests for changes from comments sent 
during the first and second Last Call Review, as agreed with the 
commenters (see Disposition of Last Call comments) and changes following 
implementation experiences from the Working Group. The Working Group 
would like to point out that the processing of media fragment URI when 
used over the HTTP protocol is now described in a separate document 
Protocol for Media Fragments 1.0 Resolution in HTTP.

For convenience, the differences between this CR version and the Second 
Last Call Working Draft are highlighted in the CR Diff document. The 
differences between the Second Last Call Working Draft and the First 
Last Call Working Draft are also highlighted in the CR Diff document.

Publication as a Candidate Recommendation does not imply endorsement by 
the W3C Membership. This is a draft document and may be updated, 
replaced or obsoleted by other documents at any time. It is 
inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the 5 February 
2004 W3C Patent Policy. W3C maintains a public list of any patent 
disclosures made in connection with the deliverables of the group; that 
page also includes instructions for disclosing a patent. An individual 
who has actual knowledge of a patent which the individual believes 
contains Essential Claim(s) must disclose the information in accordance 
with section 6 of the W3C Patent Policy.
