ITS - New Orleans, LA - January 2018

Tuesday, January 30


chair: Paul Knapp scribe: Paul Knapp

  1. General Announcements:
    • Co-Chair election: Paul Knapp is running for re-election
  2. HL7 over HTTP
    • Vassil raised that the HL7 Over HTTP should be pulled or copied from the V3 spec and published in a more general manner.
  3. KNART specification
    • Lorraine reviewed the status and go forward path for the KNART specification of which ITS is a co-sponsor. Hopefully the will have an Errata to the existing STU for April 1 and then a new STU for September 2018.
  4. FHIR-I
    • Issues in persisting and using FHIR resources in marked-up form: eg. XML, JSON, Protobuf (Google), RDF, as opposed to harvesting the content and storing in a canonical model (SQL, Columnar). The effort here is to bring together discussions of issues and approaches not to prescribe what persistence methods to use.
    • A Protobuf document will be provided as DRAFT for the May ballot and review in the May 2018 WGM.
  5. Bulk Data Transfer
    • ‘Newline delimited JSON’ – build data exchange format has been added as DRAFT to the specification, DRAFT again in May and perhaps STU in September.
  6. Announcement:
    • application/fhir+xml registered, application/fhir+json soon.
  7. FHIRPath
    • Both the CQL and FHIR use the FHIRPath specification.
    • Motion: Ballot FHIRPath as a normative specification with appendices D (V2 MAP), E (Tooling and Implementations) and F (References) as informative. Grahame/Bryn 6-0-0
      • Discussion:
      • FHIRPath is an expression syntax to refer to instance elements which is used in FHIR and potentially other family methodologies or tooling. CQL uses FHIRPath and any comments arising from a CQL ballot which refer to FHIRPath must be referred to ITS for consideration on the development of FHIRPath.
      • FMG wishes to advise ITS that proceeding to Normative on the FHIRPath specification does not meet FHIR Product Family rules which normally require 2 rounds of STU ballot before artifacts proceed to Normative.
    • Motion: FMG/Lloyd objects to the above motion on the grounds that it does not follow their FHIR Family Requirements of 2 STU prior to Normative. Notwithstanding that, there are no known functional impediments to Normative, therefore ITS reaffirms the above motion. Louis/Grahame 6-0-0
