  • Technical correction for THO due to corrupt R3 package
    • Grahame confirmed we do not need the technical correction urgently (as initially suspected) and it can wait until next freeze/release scheduled for 2/12
    • Need publication request for next release (and to determine major/minor)
  • Determine if V2 can have some vocabulary outside of THO
    • There are examples/user defined tables that have been added to THO
    • Proposed Motion (pending quorum): The TSMG will propose a means of identifying and tagging HL7 Value Sets and Code Systems in THO whose sole intended purpose is to be used as examples.
  • Duplicate CS/VS across FHIR core and THO
  • Duplicate URLs in THO
    • Duplicate URLs in THO for CVX: vs.
    • Suggestion to confer with HTA to see what information from the retired page needs to be ported to the active page
      • Work complete via
        and ready for review/vote
    • Marc suggested we may not need to implement this based on discussion at WGM for an IG Publisher request to have duplicate OIDs be a warning if one of the entries is retired
    • JB: please vote when quorum established on the UP ticket & submit this as a proforma change (before the freeze on 2/12)
  • Recommendation from Vocab to TSMG on handling of THO OIDs
  • Review fix for 'All HL7 Code Systems' tab
    • Jira
    • Options are to break down by product family or maintain two separate manifests (more work and more prone to error), more details in ticket comment
    • Discussion included adding the following comment to the ticket: 
      • Discussion in TSMG meeting 13Dec22 included a suggestion to define a THO category extension that could be used to drive categorization of these pages within THO, reducing the need to manually maintain manifest lists for each product family, etc.  This could be enabled through a custom xslt template.  This would be a good solution conferring a reduction of work for THO maintenance. 
    • Decision on this topic requires a vote.  Quorum not established but discussion was fruitful
  • UTG/THO Subcommittee recommendation about adding release tracking information to THO
