I informed Doug and Mike of that fact, I thought that it would be discussed in the WG. Anyway it doesn't matter anymore since I think the liaison is outdated.

Yes, you're right, the problem is that liaisons usually are not considered as public documents so the secretariat or MPEG members are not allowed to make them public.

I don't think that all that's listed there would be of interest to WebApps (e.g. I'd be surprised if the WG cared about integration with BIFS or ISOFF packaging, assuming members even have heard of them), but some topics (inter-widget communication, context management, aggregation) certainly are.

That's a good question. My personal understanding was that the initial plan was to have MPEG work on specific topics (and until now the items dealt with by MPEG were not in any W3C charter), to liaise with other standardization bodies working in the area to make sure they are aware of the work done in MPEG and then to coordinate with them to harmonize the solution if necessary. So it would be good if the WG could inform MPEG about the evolution of its charter and possibly have a look at the MPEG spec, and comment on it. Anyway, MPEG is meeting next week, I'll raise your questions and try to have MPEG make a formal answer.

Regards,

Cyril
