What architectural element serves as the fundamental building block within the FHIR design philosophy?
Answer
Resources
The core design philosophy of FHIR centers around discrete, manageable entities known as Resources. Examples include a Patient, an Observation, or an Encounter. Unlike older standards that attempted to describe every clinical scenario from a top-down mandate, FHIR began by defining these modular Resources and then specifying how they connect. This modular approach allowed implementers to begin exchanging meaningful data quickly without waiting for a complete, monolithic specification to be finalized.
