TopicHL7 Terminology Single RepositoryNewReuben

Reuben started a review of the use of external terminology across HL7 products. Looking at the misalignment of information in varoius repositories (FHIR External Terminolgoies, HTA External Terminologies pages, UTG etc..). Met with Grahame last week and landed in a place where a single repository would exist within UTG. With a couple of changes...

  1. External top-level vertical is added to the hl7 terminology repository
  2. External tab and all contents would be subject to extended UTG maintenance process and HTA control
    1. Process = log request via UTG, which will get passed to HTA (and back again if necessary). 
    2. Governance = Only HTA can approve the addition and/or update to content on the External terminology pages
      1. These items are NOT open to general concensus review, only HTA approval
    3. Representation as FHIR resources = There will be a 1:1 for codesystem to naming system entries
  3. Existing HTA "External Terminologies" pages will be consumed and represented on the hl7 terminology page, then retired
  4. Existing External "Using X on FHIR" (see External tab) pages will remain in the FHIR Spec
  5. External FHIR (see External (FHIR) tab) terminolgoies in FHIR will be removed and a link to the HL7 terminology page will remain.

Timeline - TBD, though the hope is that the migration will start in the upcoming weeks

DID NOT GET TO THIS ITEM - Call ended at 4:00 ET

1) Third party copyrights

2) Canonical URLs for nursing classifications ICF, ICNP, LEP, ENP, CCC

JIRA:  FHIR-25263 - Getting issue details... STATUS


JIRA ticket has been udpated with some next steps. Need to revist this as a priority on the next call.

TopicUTG UpdateContinuousCarol/Tedregarding older external code systems (predominantly from V3 and V2) which are published on the HL7 Terminology website (through the UTG process) but not listed on the HTA External Terminologies Information confluence page nor the external terminologies page in the FHIR specification
TopicIssue with NUCCNewTed/Rob McC

NUCC HIPPA Value Sets (We did not get to this item)

For V3 value sets using NUCC, there are enumerated values (even if an intensional definition - e.g. all children of level 1 concepts").  Codes have changed....and value sets are now not generating correctly.  The value set stewards are responsible to updates, but there is currently a set of erroneous value sets from NUCC for core MIF content. Gail Kochar is responsible for NUCC but currently it is not behaving as a "well behaved code system".  
Rob H has some responsibility as maintainer of the terminology server for the FHIR build 

RobMc/Ted/RobH to sort and report back
