WG status update

Milestone review:

Next steps for additional Matroska specifications

which document to start on next?
How is the main Matroska document coming along? It is in EDIT state
now, so it's actively being worked on, but it is also 167 pages, so
it's not surprising that's taking some time.
The current publication queue is here - we're #2 in line
Michael and Spencer will follow up after IETF 119 if we haven't
heard from the RFC Editor by then
From last meeting minutes
- draft-ietf-cellar-tags should be fastest - 2024-12?
- draft-ietf-cellar-codec should be next, and is important -
  2025-06?
- Could different documents have different leads?
- Could we have multiple codec documents (for different codecs)?
- Perhaps one document for existing major codecs? MPEG 1/2/4 AVC
- and HEVC, AV1 (perhaps in another document) MPEG 1/2 Audio Layer
- 1/2/3 AAC PCM OPUS Vorbis AC3 DTS FLAC (FLAC has Matroska
- mapping in its own RFC already!) Text SSA/ASS SRT WebVTT
- Spencer and Michael will update the milestones in datatracker
To reference Matroska, we reference draft -21, and the RFC Editor
converts the reference to an RFC when they have a number assigned.

FLAC IESG ballot

Murray is checking with the IESG to see how he should proceed about
the new normative reference added during IESG Evaluation
He'll ask at the IESG telechat this coming Thursday
FLAC stays in AD Follow-up for now

AOB?

"Why Cellar?"
Michael sent a short note with a quote from the Library of Congress
to the mailing list
Would someone like to write a short note about Matroska being
elevated as an archival format?
Martijn is willing to write a short, cheery note about this major
milestone for the working group - interview Dave, quotes from
archivists?
From Dave = "Kate Murray at Library of Congress would likely offer a
quote, but in her govt role it would be rather factual"
This is IETF-wide, but also for people outside the IETF (for
example, ISOC)
Martijn will do a first draft and send it to the mailing list
This will be most helpful if we have a draft by the time Matroska is
published

IETF119 is in Brisbane, March 16 to 22.
Next meeting is 2024-04-09. (No March meeting, two April meetings)
