Pierre and all,

Here is a first draft of the Call for IMSC1 implementation.
Let me know if you have any comments.




Dear IMSC1 implementer,

This is a Call for Implementation for "TTML Text and Image Profiles for 
Internet Media Subtitles and Captions 1.0 (IMSC1).

The W3C Timed Text Working Group [1] published its latest "TTML Text and 
Image Profiles for Internet Media Subtitles and Captions 1.0 (IMSC1) 
[2], a W3C Candidate Recommendation dated 19 May 2015.

W3C publishes a Candidate Recommendation [3] to indicate that the 
document is believed to be stable and to encourage implementation by the 
developer community.

Implementation experience is required to show that a W3C specification 
is sufficiently clear, complete, and relevant to market needs, to ensure 
that independent interoperable implementations of each feature of the 
specification will be realized.

Therefore, for IMSC1 to exit the Candidate Recommendation stage, at 
least 2 independent implementations of every feature defined in this 
specification, but not already present in [TTML1], need to be documented 
in an Implementation Report.

The Implementation Report is based on implementer-provided test results 
for the IMSC1 test suite [4] (tests and sample content) maintained by 
the Timed Text Working Group. The Working Group does not require that 
implementations are publicly available but encourages them to be so.

In order to demonstrate adequate implementation experience, the Timed 
Text Working group invites all IMSC1 implementors to report on their
implementation (product, prototypte, scripts, etc...) using the online 
Implementation questionnaire [5].

If you wish to make comments regarding this specification, please send 
them to public-tt@w3.org with [imsc] at the start of your email's subject.

Looking forward for your contribution with your IMSC1 implementation.

Thank you,

On behalf of the Timed Text WG,

Thierry Michel
