Having glanced through Brian Frank's units.obix file (attached), it seems to me
that the UnitsML TC and the oBIX TC (also part of OASIS) would both benefit from
collaboration.
Maybe Brian could dial in to the next UnitsML TC conference call?

Honestly I didn't know there was a UnitsML TC. But yes, I would love to see
collaboration. I'm am especially interested in defining a standard naming
convention for units which can be used (similar to what the Olsen database has
been able to do for naming timezones). It seems soooo much work goes into
*modeling* units, that everyone underestimates the huge value (and much simpler
task) of *naming* units.

Hi Brian,
Thanks for the suggestion! I don't have a lot of time this week to do a
detailed analysis, but at a quick look I can't help wondering if you have been
in touch with the UnitsML TC at OASIS? I just joined that TC myself in the last
couple of weeks, and it looks like there is room for collaboration between
UnitsML and oBIX, especially given that they are both part of OASIS. Do you
mind if I mention this to the UnitsML TC?
Best Regards, Karen Legrand

If you are looking for a unit database to test against, you might want to take a
look at the oBIX unit database (attached). It has around 300 or 400 units with
scale/offset linear conversions ratios using this formula:
unit = dimension * scale + offset toNormal = scalar * scale + offset fromNormal = (scalar - offset) / scale toUnit = fromUnit.fromNormal( toUnit.toNormal(scalar) )
Another easy way to get at the database for scripting is the Fan programming
language:

Legrand, Karen a écrit :
Has anybody made any progress on setting up an environment where we can work on
a TCK? I have been looking into trying to get hold of NIST's UnitsDB, with the
idea that we could test against that for the unit conversion tests. I don't
even want to think about how much work it will be to code for blanket test
coverage of the conversions without any shortcuts.
I'm not aware of a SCM (Subversion? Mercurial?) with the code. Maybe Jean-Marie
can provide us an update? Once we have a SCM, I could contribute JUnit test and
a Hudson build server.
