Hi all,

PROPOSAL: Draft a WG Note describing the profile short name
    registry and updating the IANA media registration, based on
    what's in the current profile registry wiki page plus the
    addition of the codec parameter to the existing TTML media type
    registration.

    nigel: Does that address Cyril's concern about using the codec
    profile?
My concerns were that:
a) if the registry is a note, it should not contain normative material

whether a publication is used normatively is not a property of the publication, but of the reference to the publication; there have been many W3C Notes published with technical material that have been used normatively by other publications;

That's true but maybe the question we should be asking is: does any organisation hoping to use this document have a strong requirement for it to have Recommendation status? And if so, what concern do they believe will be mitigated by that? Our current view is that a Note is fine.


b) the registry does not confuse people by redefining what MPEG defines
c) the use of the identifier would be beneficial even outside of MPEG files, in particular for plain TTML over HTTP.

a) has been addressed by some clarifications that Mike made.
b) is partially addressed as the 'stpp' row is still there.
c) is addressed by the IANA update.

    mike: Yes, without going into all the details, the RFC is out
    of date, but we can independently
    ... proceed here with tidying up, to resolve any public use or
    adoption. Cyril is concerned
    ... more globally about non-W3C infrastructure issues. We can
    solve ours locally.
I'm not sure what this means, which RFC you are talking about or what you mean by "non-W3C infrastructure issues".

FYI, the next MPEG meeting is at the end of October. Can the Note be published by then? In any case, can I ask that the group makes a liaison to MPEG informing about that Note so that MPEG can decide on using it for defining its codecs parameter?

Cyril
