Agenda

3. Query sources

Minutes

Minutes/Conclusions Reached:

1. Lisa's proposal: simply allow terminology in CCDA; this will support alignment with FHIR
   1. CCDA not ever easy to change, but industry is looking at it. If it can change, now is the time.
2. Analysis positions:
   1. we want negation to be explicit (not buried in precoordinated terminology)
   2. we want negation to be concrete (not modeled as a Boolean)
   3. this means specifications should represent negation explicitly and concretely, or provide instructions on how to derive explicit & concrete information directly in the specification (i.e., not in a long separate document).
   4. Possible stronger statement: specifications should represent transform to 'other widely adopted specifications'
   5. Or even FHIR & CDA specifically?
      1. #2.4 allows extension in future. Look into mechanism for referring to current judgment on 'other widely adopted specifications'
3. DAM for ballot
   1. Looks like a useful approach
   2. might help to map bits to RIM
   3. Ask ARB/TSC how this might support policy
