  • Subcommittee work in progress
    • Approve THO cleanup efforts (as Pro Forma?)
      • Fix the "All HL7 Code Systems" tab to ensure that external code systems are not included:
      • Add tabs for deprecated content (based on deprecation task force)
      • Add default value of 'true' for all code systems without a <caseSensitive> element (mainly external code systems) unless otherwise specified to resolve warnings in THO
      • Motion to Approve: JB / Second: DG  Motion passes 7-0-0
    • Subcommittee proposes additional call to review UTG tickets in Consensus Review

        • V2: Michael Faughn, Frank Oemig, Rob Snelick
    • Vocab WG follow-up: Policy Requiring Identification of Stewards for HL7 (Internal) Code Systems
      • In Vocab WG - Motion passed: Vocab WG recommends that TSMG implement a rule stating that:
        Every HL7 code system in THO must have a steward WG.  The steward WG has to be one of the WGs that are authorized to propose making changes to an HL7 code system in THO. 
      • Out of 797 code systems, 236 do not have a Steward value
        • 38 V2, 147 V3, 47 FHIR, 3 unified code systems
      • Current supported solution is to make corresponding Management Group responsible (by either having them assign the WG responsible or by assigning them to the MG itself)
        • In the FHIR space, it could be the resource owner
          • Vocab WG to run a query for each code system across FHIR core to identify the resources and their responsible WG(s) for each listed code system.
            1. Robert Hausam will check with Lloyd and whether and how we can do this.
            2. Will bring this back for the Vocab call in 2 weeks.
        • V2 - make the V2 management group responsible
        • V3 - will be a multi-management group exercise.  CMG will take a look at the V3 sets first.  FMG will take a look at the list next to determine which is the appropriate responsible party.

    • Sub-committee eVoting: added section "quorum for the TSMG requires that a co-chair and at least 50% of the current members be present... Any sub committee meeting... "  this section should be reviewed by the TSMG membership and approved in an upcoming meeting before going to the TSC
