Hi -
Thanks for the comments.  Please see my responses.

I used the EIDR draft as a template
(  Ad-ID is similar,
but for advertisements where as EDIR is for program content.

Major Issues:

This is an informative document that states "Ad-ID is the industry
standard..." but doesn't provide a clear normative reference to an industry
standard at that point. I assume that would be [SMPTERP2092-1]. If so it
should be referenced right there. Unfortunately it's behind a pay wall
( The IESG needs to confirm
whether that's acceptable.

   SMPTE can readily make SMPTE RP 2092-1 available privately to IESG
members (through a liaison).
   Note that SMPTE and ISO exceptionally make standards available for free
upon request.

>   An Ad-ID Identifier consists of a unique eleven character string
>   or a unique twelve character string (video codes only).

What's a "character"? ASCII or UTF-8?

It is Alphanumeric. Our character coding is UTF-8.  Im not sure if this is

The informative reference [Ad-ID-INTRO] doesn't seem to know whether it's a
technical appendix or a reference, and the URL that it cites is unhelpful.
The material at seems to
be what is needed but partly duplicates what is in the draft. Maybe this
material is only given here because the actual SMPTE standard costs more
than $100? If so, I think it should be clearly labelled as informational
material and that only the SMPTE document is definitive.

  This is meant to just be an introductory text for what an Ad-ID is.  That
being said, perhaps a link to here is more relevant:  This is also referenced
in SMPTE RP 2092-1
