Excuse me, I am not fully familiar with the lingo here. So you were Chief
Technical Officer from the Linux Foundation on the ISO LSB project?
And then what would that mean?

that is understood.

So you would favour a scheme that would not introduce this overhead on
travelling and meetings?
I do understand that there may be requirements on change of wordings
for ISO text, but at least some of that has already been done.
I don't know how much is left but I am willing to help having a look into that.

Yes, we can risk that. But then, if we have a POSIX Austin Group
like organisation, having all experts in one group would counteract
such a tendency. It has not happened in the Austin Group yet, and they have
been functioning for more than 10 years. And the Austin group was formed
because we have had similar troubles as you report for the LSB at ISO work.
So there already were people and politics and other sharks in the water for
the POSIX ship. We got away with those troubles by more adequate organisation.

I was there too, both in the OOXML case, and the old TCP/OSI battle,
and I agree with you.

I would like an ISO standard that is exactly the same as the LSB standard,
and I think I see ways to do this. The ways I foresee have been played
out a handful of times before with good results (IMHO).

Yes, and that is the reason that it is important to have a good
plan for syncronization of the ballotting and maintenance processes of the
organizations involved. The Austin group processes scheme is fairly good,
but I think it should be fitted to our two organizations.

I have also allways thought that the 512 b blocks were cumbersome
for reporting. Anyway, thanks for your insights into some LF
rationale for the state of the play.
I think somebody promised in the teleconference to approach
LF to hear what they may have to say and their attitude to a revised
ISO standard, and the future mode of cooperation with ISO on LSB.
Am I right?
