Map CDA to FHIR and Back with FHIR Mapping Language
summary
Shows that CDA documents map to FHIR and back by modeling CDA as a CDA Logical Model as StructureDefinitions, writing maps in the FHIR Mapping Language and running them with engines (the Java reference implementation and Helix C# mapper). Demonstrates a working pipeline: maps uploaded as StructureMap resources, transform operation returns a FHIR Bundle, maps packaged in an ImplementationGuide for Swiss e-medication, and round‑trip checks validate fidelity. Notes practical limits: steep learning curve, lock‑in to FHIR tooling, occasional need for extensions for cardinality.
