No description provided.

Required change to support HL7 FHIR Normative CodeSystem:

• Add Extension (JSON) as core field for Source
• Add Extension (JSON) as core field for Concept
• Add Meta (JSON) as core field for Source [We'll need to add it to Collection too.]
• Concept Name Type (Only required for one CodeSystem)
  - FHIR requires Coding Type of concept's designation.use field
  - Coding usually have four fields - system, code, version, display
  - We need to store concept name type as Coding JSON resource or create new json field in LocallizedText table to store
  Coding JSON resource
  concept.designation.use example - https://www.hl7.org/fhir/codesystem-resource-types.json.html

One gap that might not be documented yet: FHIR IDs allow any character, whereas OCL Mnemonics are more restrictive. Might need to handle specific characters.
