Re: [PNG] Meeting discussion topics

Dear all,

I should be able to join Monday at 8:30 am. I think for the gainmap ISO
spec, I've shared them with group, but what I'm waiting for is the W3
policy that the specs must be open for PNG 4e to adopt it. Once I have
that, I can ask ISO if they can make the gainmap ISO spec public (no
guarantees they will say yes, but I can try).

Sincerely,
Fares
