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
  • Responses for RFP for web-based terminology editor to support UTG/THO were due 7/1
    • Should hear about results soon
New Business30 JB/RD
  • Reminder to review Terminology Expectations for IG Developers 
  • TSMG approved THO released 3x a year
  • Scheduling next THO release
    • Grahame has indicated that we need a release of THO ASAP:
    • Marc has indicated that he is working on the ~9 tickets that need to be implemented in the CI build this week to prepare
    • There are other considerations in preparation for R5
      • Removing identifier systems from R5
      • Adding external code system metadata stubs from HTA pages to THO and removing external code system identifier information from R5
      • Handling value sets that reference THO anchored code systems
      • Handling content in FHIR spec that is anchored in THO (see next topic) 
    • TK: The only items in Sent for Implementation are HTA items that do not include coded content. What are people looking for with the release? 
      • JB: Follow up with Carol and Rob about what THO content is driving the need for the release
      • TK: Possibly we could have a THO release by 7/29 with Sent for Implementation content only
      • There is also an issue with one of the packages, 3.1.0, that wasn't reported as an error or warning so is happening transiently while content is processed during the build with a duplicate value sets. Concerned with what caused it or where it came from. Unsure if this will be incorporated in next 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
    • JB to respond to FHIR ticket to start conversation with Grahame
  • Review FHIR-28612 - Getting issue details... STATUS
    • Discussed adding a tab to list and describe all extensions in THO
    • This will be brought to Vocab call this week and TSMG Monday 
    • Individual extensions would be added through UTG change proposal
Subcommittee Work in Progress15JB/RD
  • 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
      • 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 UP-322 - Getting issue details... STATUS
        • Changes submitted
    • Need to start discussions (with FMG?) about having ability to render extensions in THO
      • Ask Reuben to follow up
  • 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
      • 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
