[MPEG-OTSPEC] Proposal to discontinue the AdHoc Group

1. I agree with Behdad.

I’m grateful that he’s been expressing his frustration over the process
very openly.

I also know that he’s not isolated — I think many people are frustrated
over how the system works.

2. I’be been privileged to have been part of the evolution of the common
font format for nearly 20 years now, and I’m grateful to have been invited
as an “expert” to various gremiums.

However, I think there is a distinction, one that Dave has raised pointedly
several times, between the ISO OFF standard and the vendor-specific
formats.

3. I have no problem with Microsoft, or Microsoft and Adobe, to have the
deciding vote on changes in Microsoft OpenType, or make unilateral changes
to that format.

OpenType is a Microsoft trademark, it’s a Microsoft product, and nobody has
an obligation to support it.

4. Similarly, I have no problem with Apple to have the deciding vote on
changes in Apple TrueType, or make unilateral changes to that format.

TrueType is an Apple trademark, it’s an Apple product, and nobody has an
obligation to support it.

In fact, Apple had been much more “unilateral” in how they changed TrueType
than Microsoft had been with regard to OpenType.

5. I cases of both OpenType and TrueType, I always knew who the “host of
the party” was, and that I was a “guest”.

6. I never really understood the ISO OFF process, hovewer. In fact, up
until recently I didn’t follow OFF much at all. But with OFF, I think the
“host–guest” delineation is muddled. It seems that the process of
developing the OFF standard is trying to both eat the cake and keep it.

On one hand, it tries to mirror whatever goes on in OpenType (but not
TrueType), so it “follows”. On the other hand, it occasionally tries to put
forward some changes in its own, so it tries to “lead”.

In the end, it had the appearance that it’s not clear whether ISO is really
decisive about the OFF standard or it isn’t. But I’ve never worked on any
other ISO standards, so I really don’t know what is the “ISO way”.

7. What I do know is:

Let’s say I want to propose a new SFNT table such as LABL (which I believe
addresses a really valid need):

-
https://github.com/twardoch/opentype-layout/blob/master/proposals/20200423-AdamTwardoch-LABL-table.md
- https://github.com/twardoch/opentype-layout/issues/1

Currently, I have no idea whether I should be proposing this to the ISO OFF
AHG, the ISO OFF WG, to Microsoft, or to Apple. I don’t know whether any of
those paths has any chance of succeeding, and I don’t even know how I
should go about finding that out.

I assume that some of that roots in my ignorance, but still, I’d be
surprised if anyone stepped up and to could tell me “Well, Adam, this is
the process: you do A, then B, then C, and in the end you know if your
proposal will be in the next revision of OFF or if it won’t, and if it
won’t, you’ll know why.”

8. So perhaps the reason why I haven’t pursued my LABL proposal any further
is not only because I lacked dedication, but also because I still don’t see
the correct path I should be choosing. Which is disheartening, as you may
imagine.

9. I suppose many will agree that the process *as it is today* needs
redefining, and that the remnants of past processes that are still lurking
here and there are not the best possible way to move forward.

*If* we want to move forward, that is.

10. I’d like to express my support for the notion that Behdad’s complaint
is heard by a fair and impartial group of people with authority to change
how OFF operates.

Thanks,
Adam
