Formal notice of proposed name change

From: Sean Hayes <Sean.Hayes@microsoft.com>
Date: Fri, 16 Oct 2009 16:19:17 +0000
To: "public-tt@w3.org" <public-tt@w3.org>
Message-ID: <8DEFC0D8B72E054E97DC307774FE4B9111C3CC@DB3EX14MBXC315.europe.corp.microsoft.com>
The Timed Text working group is entertaining a proposal to change the name of the format to:

Timed Text Markup Language

and the title of the specification from:

Timed Text (TT) Authoring Format 1.0 - Distribution Format Exchange Profile (DFXP)

To :

Timed Text Markup Language (TTML) 1.0

The concept and name Distribution Format Exchange Profile (DFXP) will be retained, but relegated to the discussion in the body of the document.

The TR URI would change to  http://www.w3.org/TR/ttml

The media type would change to:  application/ttml+xml

The namespace URI's would change to undated URI's e.g.:

Name

Prefix

Value



Default

tt:

http://www.w3.org/ns/ttml



Parameter

ttp:

http://www.w3.org/ns/ttml#parameter



Style

tts:

http://www.w3.org/ns/ttml#styling



Metadata

ttm:

http://www.w3.org/ns/ttml#metadata



Profile

none

http://www.w3.org/ns/ttml/profile/



Feature

none

http://www.w3.org/ns/ttml/feature/



Extension

none

http://www.w3.org/ns/ttml/extension/




We will use the file suffix convention of .ttml for any generic TTML document, and .dfxp for documents which are known to conform to a defined exchange profile.

The DFXP profile designators will be known by the URI's:

DFXP Transformation

http://www.w3.org/ns/ttml/profile/dfxp-transformation

DFXP Presentation

http://www.w3.org/ns/ttml/profile/dfxp-presentation

DFXP Full

http://www.w3.org/ns/ttml/profile/dfxp-full


The test suite would be updated to follow these changes in the week following the adoption of this change, implementations would be expected to adapt to these changes in order to be considered as passing the tests as evidence of implementation.

The deadline for objections to the change is the meeting on 23/10/09
