Agenda Topics

  1. Ballot target: DAM; support for policy
  2. FHIR/CDA alignment
  3. Query sources


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
