[annodex-dev] captioning and cmml

[Silvia Pfeiffer]

Hi all,

I'd like us to discuss and make a decision on what to do with subtitles in CMML.

Chris Chiu has created an awesome wiki page that discusses the issues
and provides three options to go forward:
http://trac.annodex.net/wiki/CmmlSubtitles .

Option 3 assumes that subtitles will be handled outside CMML - in
something like DFXP (see
http://www.w3.org/TR/2006/CR-ttaf1-dfxp-20061116/), which would need
to be serialised and a Ogg media mapping defined to be encapsulated
inside Ogg.

While this is a clean solution to a problem that is so far orthogonal
to CMML (with its hyperlinking ideas), it would be nice if we could
have a simple means to include subtitles or anime type formats
directly inside CMML. Option 1 is a very unclean means of doing so, so
my suggestion is to adapt Option 2 and create an additional element
for CMML called "caption". This element can adopt some of the
attributes that the W3C DFXP standard has defined for captions.

I'd be curious to hear your positions on this.

Cheers,
Silvia.
