Hi Mark, all.

This cannot be done in the IG because IG's are forbidden by W3C rules from writing specs. [] Membership: Note also that the CG, unlike the IG, allows for direct participation by non-W3C members, which should help with the CG focus on external specs.

The participation argument made sense in the case of the Web & Broadcasting BG, where there was a significant number of non W3C-members wishing to participate in the conversation. It is unclear whether this is the case here.

Regardless, the above sounds more like a case for our IG to become a CG than a genuine need for a new group. Maybe worth an agenda item at the upcoming f2f?

The focus of the CG is a subset of that of the TF, yes. And it may be a good thing to have a spinoff group working on this spec at some point. It is however not sustainable to expect a given group to give input and feedback to itself across several mailing-lists. Having an IG spin off CGs, frankly, sounds like an unnecessary fragmentation burden.

I would like to hear the opinion of the IG - and the Media APIs TF members in particular - about such a setup. I would personally prefer a solution where our IG would become a CG, have the right to go from use cases to draft spec, and then (and only then) spin off WGs whenever necessary.
