Logical Model: Core Data Element (DAK)

Official URL: http://smart.who.int/base/StructureDefinition/CoreDataElement				Version: 0.2.0
Active as of 2025-10-14				Computable Name: CoreDataElement

Logical Model for representing Core Data Elements from a DAK. A core data element can be one of: a ValueSet, a CodeSystem, a ConceptMap, or a Logical Model adherent to SGLogicalModel. This is the ONE EXCEPTION to allowing FHIR R4 models into the DAK LMs.
