Woody Beeler responded with the status of the HL7 3.0 modeling of
observations.  Please see the attached email.

Tim -

First, you are correct that there have been SIGNIFICANT changes to the 
modeling of observations as a result of the proposals reviewed at the RIM 
Harmonization Meeting held three weeks ago in Boston.  The current status 
of the model is that Karen VanHentenryck, supporting Ted Klein, is 
preparing RIM Version 0.85.  This will be available in a couple of weeks. 
 It will contain the essence of the changes correctly stated, but will be 
subject to a "technical correction" prior to the end of August. (RIM 0.86 
will include the technical correction, and will be released for use at the 
September HL7 Working Group Meeting.)

At present, I am in Australia and cannot help further.  I trust that Ted 
and/or Abdul-Malik can steer you to better information to support your 
efforts.

Yours .... Woody Beeler
