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

I used the EIDR draft as a template
(https://tools.ietf.org/id/draft-pal-eidr-urn-00.txt).  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
(http://ieeexplore.ieee.org/document/7291518/). 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
needed.

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 http://www.ad-id.org/how-it-works/ad-id-structure 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:
http://www.ad-id.org/how-it-works/ad-id-structure  This is also referenced
in SMPTE RP 2092-1
