Introduction to FHIR Messages and FHIR Documents
summary
Claim: FHIR ≠ REST — FHIR supports four exchange paradigms (REST, Documents, Messaging, Services) and most implementations use REST but messages and documents solve different problems. Documents are a Bundle:type=document with a Composition header, mandatory narrative text plus referenced computable resources, usually archived as a blob and not edited. Messaging is a MessageHeader with trigger event in a message bundle (notification/query/order), peer‑to‑peer with acknowledgments; common in Denmark/NHS, dates to 1960s. Mentions NLP for coding, signatures, and flexible transports.
