Agenda Item
  • Rollcall & Proxies
  • Note that meetings are recorded
  • Approval of meeting minutes


  • Started adding to UTG & THO Subcommittee Policies and Processes page
    • Review and see what else should be added 
  • To be scheduled: Separate session to go through UTG process with those interested (and record)
  • The CI build will freeze on 2/20 (i.e. no more proposals will be processed) with release of THO v3.1.0 to kick off shortly thereafter
    • Grahame is looking into resolving ~400 warnings prior to this release (discussion occurring on Zulip)
    • Fixed issues with IG publisher update, but no update on resolving the warnings
  • Working on UTG Task Force recommendations
  • Sprint 2 of UTG Jira development items is in progress, focusing on release tracking
    • Still need to carve out time to work on this
  • Funding secured to help with automating some of the Jira workflow steps
    • Ted meeting with new resource, Lawrence, to determine areas that can be automated to ease burden on submitters
  • Defining requirements for a web-based UTG Editor
  • THO work in progress
    • List all resources by <title>: UP-277 - Getting issue details... STATUS
      • I'm not sure this is possible anymore
      • Look at the all code system file vs. the others for example, it may be doable
      • Need Grahame or Lloyd to clarify, Rob believes it does not exist
    • Add Identifier Systems from FHIR to THO: UP-285 - Getting issue details... STATUS
      • Identifier Systems have been created in a branch, other cleanup work included
      • Discussed Lloyd's comment about enumerating all of the country passport codes
      • Must respond to him about OID issue
      • Suggest due to time constraints we can deal with them later
      • Ted, Reuben, and Jess to discuss adding history entries
    • Handle external content in "All Code Systems" tab
    • Moving "Using X with FHIR" pages
      • Good progress, table and links work
      • Need decision from Grahame and Vocab about Using SNOMED CT with FHIR that includes a link to another page that should likely be ballot bound. It documents all parts of the FHIR spec that use SNOMED. Need to find a new place to link it from.
        • The 'Defined Externally' page will link to THO so we can add a statement there
      • Will move ICD pages in and browsable and then will likely be updated later. We will discuss on this week's Vocab call
Subcommittee Work in Progress40JB
  • THO release schedule
    • Update from discussion on main call
      • Bryn suggested to TSC three releases a year with flexibility to release at any time
      • There are concerns that HL7 doesn't have the resources to commit to the number of releases
      • TSC needs additional understanding about tasks and the process for publishing a THO release
      • Most of it is documentation and will be followed for the 3.1.0 release
      • Release takes about 3 days (i.e., waiting for builds), heads down time is about 8 hours
        • Very dependent on the IG Publisher, has taken up to 2.5 weeks in the past
      • Suggestion not to release if not enough changes have been implemented in the CI
      • THO is changing functionally with each release and is hard to release, that makes it hard to estimate freeze dates
      • Bring up concerns on tomorrow's main call, this involves TSC and HQ
      • Will be easier to create a schedule once UTG/THO is more stable, then can focus on consistent/reliable delivery
    • Discuss best way to align with ballot cycle
      • Build freeze dates
      • TSMG approval dates
    • Content deadlines
      • May 2022 - March 27, 2022
      • September 2022 - August 7, 2022
      • January 2023 - December 6, 2022
  • Workflow process for use of internal code system identifiers in FHIR and beyond
  • 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
    • Next Steps
      • Move forward with plan to request that Management Groups provide at least one person to be part of an OSG for the Product Family OSGs
        • Draft email provided to TSMG Outreach Subcommittee for review
        • Lisa provided feedback that even after relaxing requirements there just aren't enough people to do the work, although it is important
        • Perhaps the new implementation division should be involved in this issue
      • Ask Rob and Peter for help recruiting for Realm-Based OSG
      • Ask TSMG main call for Vocab/TSMG members for the Vocab OSG
      • TSC clarification
        • Need to ask for clarification for ad hoc OSGs (separate request) and how OSGs may change but membership does not automatically refresh on tickets already in Consensus Review
        • Expectations for when members of an OSG need to change
