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).

  • Fix the "All HL7 Code Systems" tab to exclude external content
    • Tracked via UP-320 - Getting issue details... STATUS
    • Two options for approach (listed in comments of ticket)
  • Handling THO anchored content in the FHIR spec FHIR-37440 - Getting issue details... STATUS  
    • 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)
      • There are 42 code systems anchored in THO that are only in the FHIR core specification
        • Need to do same analysis for value sets
        • Assume they need to be moved but would like to finish analysis
      • There are 72 code systems and 190 value sets that are potential duplicates across THO/FHIR
        • Continue to discuss how to address changes across the following code system elements:
          • meta.lastUpdated (all) - not consequential
          • date (all) - not consequential
          • url - once moved, should all be anchored in tho
          • experimental (19) - we assume that all code systems may have been set to false upon moving to THO but this requires verification
          • title (23)
          • valueSet (70)
          • meta.profile (62) - not consequential
          • description (22)
          • publisher (18) - not consequential
          • name (8) - consequential, involve WGs if needed
          • contact (18)
          • status (17)
          • oid (25) - consequential and require cleanup, need to understand how this is happening from Grahame as there are duplicate OIDs across and within THO and FHIR (urn:oid:2.16.840.1.113883.4.642.1.0)
          • property (1)
          • hierarchyMeaning (1)

            • standards status

            • fmm
          • concepts (18) - consequential, involve WGs if needed
        • Discuss how to address changes across the following value set system elements:
          • name (29)
          • oid (5)
          • status (19)
          • standards-status (10)

          • compose.include.system (19)
          • date (180)
          • extensions 
            • fmm (25)
    • Goal is to get a list of resources we consider duplicates or easily categorizable fixes (only have non-consequential differences) and then a list of duplicate resources that need to be consolidated/resolved
      • Grahame can handle the duplicates and WGs will need to be involved in the resources that need consolidation
  • Cleanup of HSCR tickets 
    • HSCR-139 - Getting issue details... STATUS
    • HSCR-118 - Getting issue details... STATUS
    • HSCR-97 - Getting issue details... STATUS
