ISO 80000
Jukka K. Korpela
essential changes, if any, to the principles in ISO 31?
The group FAQ seems to still refer to ISO 31, but according to the ISO web
site, ISO 31 (or at least several parts thereof) have been obsoleted by ISO
80000.
I tried to find DIS versions of 80000 floating around on the web but
couldn't find any. Maybe they have become more cautious...

It might have been easier to remember if we had been told explicitly
what ISO 80000 is about.
<http://en.wikipedia.org/wiki/ISO/IEC_80000> refers.

Page <http://www.cs.tut.fi/~jkorpela/math/index.html> has one instance
of the English word "canvas". Since HTML 5 offers the 'canvas' element,
it might be well not to use that hexagrammaton for other purposes in the
page if it can readily be avoided. In any case, the intended
implication of "canvas" there is unclear to me at first sight - would
"window" serve better?
You say "1 005 is unambiguous." - that is only so if the
context unambiguously requires a single number.
Firefox, Opera, Safari & Chrome support, in recent versions that I have,
the 'canvas' element, and all bar Opera support writing text to it -
demonstrated in <URL:http://www.merlyn.demon.co.uk/sitedata.htm> and
<URL:http://www.merlyn.demon.co.uk/js-grphx.htm>. In those pages, the
completed canvas ''art'' is visually replaced at completion by a
corresponding PNG, which can easily be saved for publication.
Therefore, ISTM that mathematics can reasonably easily be represented on
a 'canvas', and either the JavaScript code + 'canvas' or the PNG can be
included in Web pages (ignoring current MSIE users <g>).
The same applies to maths with diagrams; in technical work, a diagram
can often be expressed numerically, which simplifies adjustment of early
drafts.
That's what <URL:http://www.merlyn.demon.co.uk/js-grphx.htm> is for.

ISO�31 and ISO�1000 were also published as an "ISO standards handbook"
under the title "Quantities and units".
http://www.iso.org/iso/support/faqs/faqs_widely_used_standards/widely_used_standards_other/quantities_and_units.htm
Perhaps there will be a new edition when ISO�80�000 is complete.
The ISO standards handbooks in A5 size are much cheaper than
the original ISO standards in A4 size.
