Antitrust statement

Professional Associations, such as HL7, which bring together competing entities are subject to strict scrutiny under applicable antitrust laws. HL7 recognizes that the antitrust laws were enacted to promote fairness in competition and, as such, supports laws against monopoly and restraints of trade and their enforcement. Each individual participating in HL7 meetings and conferences, regardless of venue, is responsible for knowing the contents of and adhering to the HL7 Antitrust Policy as stated in §05.01 of the Governance and Operations Manual (GOM).

Agenda Outline

Time Allocation


Agenda Item
  • Rollcall & Proxies
  • Note that meetings are recorded
  • Agenda check
  • No responses received for RFP for web-based terminology editor to support UTG/THO 
    • Will not be reissued due to ONC funding schedule, remains a high priority that may be included in next award
New Business30 JB/RD
  • Reminder to review Terminology Expectations for IG Developers 
  • Scheduling next THO release
    • No immediate need presented for ad hoc THO release
  • Handling THO anchored content in the FHIR spec FHIR-37440 - Getting issue details... STATUS  
    • A comparison from this commit must be performed.  Per Rob H:  this is ~1600 files, thus this cannot be a manual process to inventory / check the possible changes
    • Does this need to be done before R5 - a high priority task???
      • Can we escalate this other technical resources? This doesn't require a terminology SME. 
      • Two classes of checking
        1. Content that exists in both THO and R5 with the same canonical URL
          1. Exact match on content - remove resource from R5
            1. Grahame modified version so that it referenced THO or FHIR based on the version, not sure logic though
            2. If minor version is 1, it was migrated as part of 4.0 cleanup and 4.1 prep. If 3, it was part of prep for R4B, Ted saw some with minor version a 6
            3. All have a major version of 0 in THO due to some build hack to pull out the right thing and not give duplicate resource errors
          2. Versions are different - look to see if the content is different & determine which content is correct - a manual review
          3. Content is different, do manual review to determine which is the most up to date - another manual process
        2. Content anchored in THO that only exists in R5
          1. Move to THO and remove from R5
    • Michael has completed an initial review 
      • Assumption is that resources will share <id> (we know this isn't a rule but we need something to link the resources)
      • Will go back and compare NPM packages for THO CI build and FHIR CI build
      • Some cleanup to occur on the list of discrepancies
      • Once we have this list we will be better positioned to compare the resources
        • We know this will likely be iterative to determine which changes matter (we know url and version will be changing)
        • Need reliable patterns for making block decisions/updates
  • Confirm scope of moving over external info from
    • FHIR-35933 - Getting issue details... STATUS
    • See resolution in ticket above
    • Entries with "Using X with FHIR" will remain, but will be linked to THO
    • Changes to bulk update from HTA pages do not need to occur prior to R5 freeze but would like to get done before R5 is published (early 2023)
      • Only non-substantive changes can be made during this time
      • Other things would need to go through FMG
    • For identifier systems, Jess to coordinate with Lloyd to get them removed from FHIR spec since they have already been added to THO
Subcommittee Work in Progress15JB/RD
  • Reuben to raise adding extensions to THO in their own tab (on main TSMG call)
    • Related ticket:  FHIR-28612 - Getting issue details... STATUS
  • THO cleanup
    • These tickets have approval from TSMG to proceed in UTG
      • Fix the "All HL7 Code Systems" tab to exclude external content UP-320 - Getting issue details... STATUS
      • Add tabs for deprecated content (based on deprecation task force) UP-321 - Getting issue details... STATUS
  • Execution of Deprecation representation and policy in UTG/THO
    • Deprecation Policy Framework documents policy and next steps
    • Immediate priorities
      • Perform inventory of deprecated content across THO
      • Create tabs where deprecated content exists
        1. Document deprecation and expectations around deprecation on THO subtabs
        2. Must also document retired, as there is often confusion between deprecation and retirement
      • Requested IG Publisher change to render identifier.period for CodeSystem and ValueSet:
  • Task force recommendation review and implementation (voting, quorums, WG health, etc.): UTG Task Force Recommendations to TSC 
    • Tracked by HSCR-155 - Getting issue details... STATUS and its subtasks
    • Continuing to fill OSG voter slots
      • FMG: John Moerke, Bryn Rhodes, suggest adding Rob Hausam
      • CMG: Lisa Nelson, Alexander Henket, Marc Duteau
      • V2: Michael Faughn, Frank Oemig, Rob Snelick
    • Will continue to follow-up on filling Realm-based and Vocab OSGs
  • Vocab suggests that TSMG require all code systems to have a Steward
      • 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.
      • Rob Hausam reached out to Grahame to determine best way to do this
      • Might be able to use binding to determine steward by mining it out from resource that is referencing it
