The input directory contains FHIR artifacts representing the core CDA logic models with Australian extensions and adapted classes (in StructureDefinition resources).
It is an adaptation of the HL7 International CDA Logical Model Specification with specific modifications and inclusions to represent the CDA schema including Australian CDA extensions using the FHIR StructureDefinition framework.
The original (normative) schema and update schema with extensions is maintained at https://github.com/HL7/CDA-core-sd/.
