Re: scope of profile (negotiation) group

Hi,

I agree that the vocabulary should be a part of the guidance on profiles, and that profile negotiation or dcat revision are not heavily impacted by the description issue.

Or at least they should not be heavily impacted. In fact this is perhaps where we could solve the issue that Karen noted ("profile" is intertwined both with DCAT and with content negotiation): we should make sure that the DCAT and content negotiation refuse to go into the details of guidance/description of profiles and just point to another area. For example the DCAT draft should try not to include the descriptions of profiles at
https://github.com/w3c/dxwg/tree/gh-pages/profiledesc/examples - at least not until the work is stabilized in another DXWG.

I guess the easiest way to do is to give a home in the group for that work - and for the one that Karen has just started on requirements.
Ideally it would be a separate, new sub-group, to make the difference clear.
However if the people working on guidance/description are very much the ones involved in the profile negotiation subgroup, it may be simpler to formally extend the scope of the negotiation group, so that it also includes profile/guidance as a second stream of work.

Cheers,

Antoine
