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 Anyway it doesn't matter anymore since I think the liaison is outdated.

Heh! I know it's hard to get any ISO secretariat to do the right thing with liaisons, but the best for liaisons is to send them directly to this list, preferably through a common member (like the equally delightfully named ISO/IEC JTC1/SC34/WG4 recently did).

I'm sorry, I realise that my original message isn't entirely clear in terms of what "enlightening us" covers :). The web page you sent is indeed helpful in describing MPEG-U, but I had other questions. Here is the part that the enlightenment intended to cover:

"""
One reason I'm asking is because some of the work items in that document are interesting in a generic manner, and therefore are things that could make their way into WebApp's charter when it comes up for rechartering (which is soon). 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.

Given MPEG's patent policy and inexperience with web technology one can take a fairly good bet that if MPEG-U defines solutions in this space WebApps won't adopt them, thereby leading to fragmentation: something that the document above states it wishes to avoid.
"""

So to make the question more explicit: given the stated goal of avoiding fragmentation (with which I strongly agree) in conjunction with the risk inherent in doing work that won't be adopted or that will take place in parallel, are you aware of any plans in the MPEG-U community to avoid fragmentation on topics that WebApps is likely to take up?
