I hope you dont have that impression, LV2 is not finalised, I tried to
make sure I had "draft" and "provisional" in the text, but I guess I
wasn't sufficiently clear, it is very much still up for discussion.
My feeling is that it is somewhere around the Last Call stage in W3C
speak. l-a-d fortunatly not having a formal standards process ;)

Also, the units stuff I alluded to obove is not, and will not be part of
the LV2 1.0 spec, it will come soon after and live as an extension.
My plan was to crib from the scientific communities work on representing
unit values in RDF, write an early draft and post it here. It is somewhat
orthogonal to LV2 itsself, so if someone else with more time feels
motivated to work on it, please do.

The situation with LV2 is that I have ported most of my LADSPA plugins (to
verify there were no blatant problems) to a version of the draft, and we
now have 2-3 partial host implementations of the current draft. That
doesn't cover the requirements of reference implementations to my
satisfaction.

So, just to be clear, nothing has been decided. The purpose of the website
it to encourage discussion.
