FHIR Release 4 discussion

• primary focus is to take the Infrastructure Normative
  • this does not mean everything is Normative, but only the Infrastructure
  • most of the Infrastructure content is pretty stable and so it can be Normative
  • some sections will be Normative, others will still be Draft
  • dependency work needs to be done first--can't mark a resource as Normative that uses Experimental or Draft data types
• take comments on Infrastructure
  • if substantive changes are required, we will not go Normative
  • if there are no substantive changes required, then we will go Normative
• target Sept 2017 to close scope of what to include or not include in R4
  • example of search enhancements that continue to be brought up
  • discussion about bringing Observation, Medication, etc to Normative
    • need to accelerate them to Normative, but probably not R4

Tracker Items:

• 12349 - Define Special Patch resource for supporting Patch in transactions, batches, history entries - defer for later discussion
• 11419 - Reference may be by reource ID or Business Identifier. - 2016-09 core #577 - move to Block Vote
