We have in fact started meeting again regularly. The main communication channels of the ttwg are now the weekly telecons and the public list (see cc). We are currently collating implementation experience and reviewing coverage for the current specification. The charter does not allow for significant additions at this stage. Features that have not found sufficient implementations may be removed, or otherwise scoped. We will for example be considering conformance requirements for different types of implementations, including authoring, transformation and playback processors.

I did read their new charter (expires in December 2009).  The charter is basically to generate implementation experience to move TT from candidate rec to recommendation.  No new features are to be added, but some may be removed.  There may also be changes in features from required to optional based on implementer feedback.

It does not seem that they have started meeting at this point, the last meeting I could find was in April 2007 where they discussed charter extensions and implementation experience.  There may have another communication channel, since there is a reference to "will conduct work online via member reflector until WF discussion is needed".

>Definitely a group we should be talking to, especially about text equivalent associations with video fragments.  They want to come up with specifications to be able to identify points or sections of video, audio or image content using a URI.  I think our best hope with this group is that the URI mechanism they come up with can also be used to reference text equivalents for video, audio or image object being referenced by the URI.  The goal I think would be for the URI to include both the media reference and the text equivalent reference.  This would make something that is easily testable by automated tools.

>This is another group we need to work with.  Our goal here is make sure text equivalent information is a part of the METADATA format they are creating.  This maybe difficult because their initial goal is to try to harmonize existing METADATA for video and I am not sure if existing METADATA includes information on text equivalents, so there maybe push back.
