Milestone review:

  • Can the authors post updated versions of our expired working group
    drafts? Steve will submit updates
  • For Matroska, we need to resolve the remaining Discuss ballots, and
    address comments we've received
  • For FLAC, we are awaiting our AD's evaluation write-up for this

Matroska issues - Discussion of IESG Ballot positions and comments on the call.

  • John Scudder Discuss position - Steve thinks he has addressed all of
    John's Discuss points and comments
  • Roman Danyliw Discuss position - Steve thinks he has addressed all
    of Roman's Discuss points and comments
  • Other remaining AD comments received - Steve thinks he has addressed
    all of these as well
  • Michael has sent a followup email asking the ADs to review Discuss
    positions against -17
    • Spencer will follow up with ADs, on Michael's June 4 email

Review of RFC8794 GitHub structure

  • At our previous meeting, Steve reported that he has worked through
    the GitHub repo for our previously published RFC 8794, with the RFC
    8794 with errata applied at
    with a release ZIP file at
  • At our previous meeting, Spencer asked the working group
    participants to look at this GitHub structure and make sure we think
    it will work for us
  • Does anyone see any problems with this structure? Martijn thinks it
    looks wonderful
  • The GitHub repo has lots of stale branches - the structure would be
    even more wonderful if they were removed
  • We could fork the repo, so we have any older branches that we might
    need, and then delete them from the main repo
  • Are we ready to do the same thing with RFC 9043? We think our
    approach is good for other RFCs, but RFC 9043 has no errata at this

FLAC issues - Discussion on the call

  • No update required until we get the AD Evaluation comments back from
  • Private email from Murray - "expecting to finish this coming Friday
    (but ping me to keep me honest)"
  • Murray requested an early ART ART review, and this is one month
  • Spencer will follow up with Cullen Jennings, the ART ART reviewer

FFV1 v4 issues - Discussion on the call

  • No updates, check back in August


  • None noted
  • Next meeting is ** 2023-08-22**
