[MPEG-OTSPEC] AHG kick-off - we have important work to do!

[Vladimir Levantovsky]

Dear AHG members,

 

I would like to use this opportunity to remind you that we have two very
important mandates to work on (to review the updated WD text of 5th edition
OFF and to review the "Technologies under consideration" document, see links
below in my previous email) before the next WG3 (MPEG Systems) meeting that
will take place on July 17-21 in Geneva.

 

One of the mandates, the mandate #2 specifically asks to review the proposed
changes summarized in the "Technologies under consideration" document
WG03N0888 and provide  our recommendations to the WG3 on the ways forward.
The document summarizes a number of proposed changes that aren't strictly
linked to one another - each of the proposals can be reviewed and dealt with
separately, and I believe (my personal opinion, FWIW) that some of the
changes would offer noticeable benefits _and_ can be implemented with
minimal efforts. There are some ongoing discussions happening on GitHub
(where the original proposal has originated, see
https://github.com/harfbuzz/boring-expansion-spec/issues), and want to make
sure that the members of this AHG have an opportunity to follow the
discussions and stay involved. However, we do need to discuss the proposed
changes as part of the AHG work to agree on the way forward and on our
future recommendations for WG3.

 

I would like to ask all interested parties to review the proposed changes
summarized in "Technologies under consideration" document, and to state your
position for each of the proposals. Every input and every opinion is
important - statements of support, counter-proposals, discussion of possible
implementation challenges and/or concerns, backward compatibility issues
that any of the proposed changes might introduce would be a fair topic for
discussion. but it needs to happen soon! Our input contribution registration
deadline is end of day July 10 (Central EU time), and all registered
documents would have to be uploaded by end of day July 12. Remember, silence
is approval, so it you see anything that may be a cause for concern - say
something!

 

Thank you,

Vladimir

Subject: AHG kick-off - we have important work to do!

 

Dear AHG participants,

 

This is not a _typical_ AHG kick-off announcement - I am excited to
emphasize that we have new mandates, new project plan, and very important
work to do!

 

As far as mandates are concerned (approved at the last WG3 meeting, N0832),
this AHG is now tasked with the following:

1. Review the text of the updated Working Draft of ISO/IEC 14496-22 5th
edition (WG03N0847).

2. Review the content of "Technologies under consideration for ISO/IEC
14496-22 5th edition Open Font Format" document (WG03N0888) and provide
recommendations for the WG3 on if / how these changes can be integrated in
the "Open Font Format" standard.

3. Explore potential future changes and updates, and propose new items (if
applicable) for consideration in the 5th edition of the OFF specification.

 

We also have the updated project plan for 5th edition of ISO/IEC 14496-22
"Open Font Format". According to this plan, the transition of the final
Working Draft text to Committee Draft is scheduled to happen by end of April
2024. (We can do it sooner if the document is ready for promotion, but there
is a new deadline!) Once the 5th edition draft is promoted to Committee
Draft stage, it will become subject to established ISO balloting process.

 

Both output documents - the updated Working Draft including all recent
[tracked] changes (N0847,
https://www.mpeg.org/wp-content/uploads/mpeg_meetings/142_Antalya/w22589.zip
) and "Technologies under consideration ." that summarizes recently proposed
improvements and new functionality for OFF (N0888,
https://www.mpeg.org/wp-content/uploads/mpeg_meetings/142_Antalya/w22631.zip
) are now available for download and public review. I would like to
encourage you to study the documents and bring your comments, suggestions
and concerns for discussion of this AHG.

 

Thank you very much for your active participation and future contributions
to this important work!

Vladimir
