MIF Ballot

• MIF will never end
• phase #1 is complete, submitted to TSC for publishing
• Work will start again, but no timeline

Information Model Metadata documentation

• Need to better describe model metadata
• Listed on the scope statement: Lloyd.
• Beverley to enhance the scope statement, and bring it forward for formal consideration
• a companion for core principles
• for people doing design

Harmonisation - design patterns

• Lloyd explained design patterns and their impact on harmonization, for vocabulary's information
• Vocabulary was aware of the relevance and potential impacts

Discussion of HL7 IHTSDO Process

• Harmonization impacts were discussed
• in order to have a HL7 namespace for snomed, we need a gatekeeper
  • A central authority with documentation of the processes (to ensure due diligence) + with contact details (we don't need that much detail of the process)
  • Much contention about the process - some of this was discussed; vocab still to make decisions
  • General agreement that we would like to move our processes and our current vocabulary content towards a more vigorous base
  • Agreement that this consideration impacts on our direction, but shouldn't slow us from taking immediate action
  • There may be a reason to consider splitting the HL7 namespace into multiple parts with different management processes
• The interests of HL7 - both short and long term - would be well served by enhancing the existing process with the goal of moving as much of the HL7 terminology as feasible and sensible into Snomed-CT (either the core or the HL7 extension)
• We still need to measure the costs of tightening up on the harmonization process and determine where (i.e. which terminologies) they should be imposed
• Woody volunteers to participate in the process going forward, and proposes a meeting during harmonization
• Possible: Add to snomed checklist a flag for "include in Snomed-CT core" (and also exclude)
• We proposed prototyping the process this harmonization as a trial balloon

OIDs and value sets in CDA implementation guides

• Issues with how to handle US realm specific implementation guides and value sets
• OIDs not governed by HL7 are clearly marked
• CDA implementation guide value sets need to be registered in the OID registry
• CDA value sets in MIF - not known whether or when that will happen

Concept domains from International Affiliates

• only one authority can define concept domains - HL7 Intl
• affiliates can request a concept domain through harmonisation (via domain committee or intl affiliates)
• challenge if the concept domain doesn't make sense in the relevant domain committees models
  • i.e. a concept domain represents constructs in lab that assumes a central repository; intl model doesn't support that and don't want to add it
• how to manage that circumstance in harmonisation?.
• Lloyd Proposes
  • if something comes to harmonization that is not aligned, WG can reject proposal, and affiliate must work to align
  • if that turns out not to be possible (committee does not want to adopt requirement in the model), bring it forward to harmonization where it will be accepted
  • domain must still be valid against all the other rules
  • affiliates should inform other affiliates
• General agreement.
  • nice if you could hide them if you don't want to see them
  • could have a property on the domain to tag it
• Lloyd to bring to round table and then to committees and affiliate council list
