profile registry [was RE: {agenda} TTWG Meeting 2016-02-11]

Hi Thierry-

Thank you for doing the migration. Apologies for my delay in reviewing this.  It looks reasonable except for authors/editors that were added.

Although I act as a liaison to both ATSC and SMPTE from time to time, this work has nothing at all to do with SMPTE nor do I have any business relationship with SMPTE. Please back out the company addition and either delete the company field altogether or change it to my consulting corp, "TBT Inc.", whichever is more customary.

This work has been a serial collaboration starting with Glenn who wrote most of it originally. If the authors are intended to be complete, then I think Glenn should be listed.

As a reminder to all, this was drafted in response to two related needs:

1. A Request from ISO MPEG DASH that we create a short name registry to be used for DASH MPD @codecs; and

2. The WG desire to update the IANA media type registration to add an optional attribute ("codecs") that uses the short name syntax. This requires adding the standard IANA media type form (e.g.  see TTML, Appendix C [1]). 

We have completed #1, and in fact the wiki is being referenced today from DASH-IF IOP v3.2 [2]. FYI, I will inform them of our move to github for a future revision of their IOP.

We need to be rather careful at this point about changes.  I am OK with Andreas' proposal to add columns, but the other columns need to remain substantively as they were. I prefer, as Nigel proposed, that we make a new table.

We have yet to address need #2. This document was intended to be authoritative for the registry and the IANA media types registration. Due to timing I think it will also need to be authoritative for the profile shot name combinatorial syntax. So, I think we need to consider not in fact addressing issues 351 & 352 in TTML2, appendix D [3] as proposed, but consider a normative reference to this document.

I would prefer someone else maintain the document (or we all do) mostly since if all proposals fall to me to implement, progress may be slower.

Regards,

 Mike

I'm sure nobody would object if you can prepare a PR for that issue!
