The Terminology Services Management Group's (TSMG) mission is to provide terminology related services to support the efforts of HL7 participants and the overall HL7 mission to provide standards that empower global health data interoperability. The TSMG's mission includes the establishment and maintenance of a services catalogue ('the Services') in consultation with the TSC and HL7 staff. The TSMG is composed of skilled representatives from across HL7 who deliver the Services. The TSMG operates under the governance of the HL7 Technical Steering Committee (TSC) to develop and set policy for the use of terminology in HL7. 


The TSMG is responsible for the execution of the Services that include the following:

  • Management of Unified Terminology Governance (UTG) documentation, consensus review process, definition of requirements, prioritization, and resolution of the backlog of UTG JIRA tickets.
  • Oversight and publication approval of HL7 Terminology / terminology.hl7.org (known as THO) as the single, trusted and well-maintained infrastructure solution to support use of terminology in HL7.
  • Input into HL7 operations of a terminology service including its technical infrastructure
  • Development of whole-of-HL7 terminology policies to support the above services.
  • Day to day decision making around terminology.
  • Review of standards projects for terminology requirements.
  • Implementation of terminology quality criteria as defined by the Vocabulary WG that are required to be completed before balloting and publication.
  • Development and oversight of education material related to terminology
  • Promotes adoption of terminology best practices within HL7
  • Engagement with maintainers, owners and stewards of external terminologies in relation to use of their products within HL7
