FHIR provides a set of which type of resources that can be used to represent and share the adaptations to the FHIR specification in a computable fashion?

• A. Reference Resources
• B. Terminology Resources
• C. Conformance Resources
• D. Profile Resources

Answer: (C)

Describing how an implementation conforms to or adapts the FHIR specification in a machine-readable way is the job of Conformance Resources. These resources spell out what a FHIR server or client can do—what resources are supported, which operations and search parameters are available, and how data exchange should occur. They can reference profiles, value sets, and code systems to show the exact constraints and vocabularies in use. This makes it possible for other systems and tooling to discover capabilities automatically and interact with the implementation correctly. In newer FHIR versions, this role is fulfilled by the CapabilityStatement resource, but the idea remains the same: a computable description of conformance and adaptations to the specification. Terminology Resources, Profile Resources, and similar constructs address separate concerns (vocabularies, data constraints for specific uses, etc.), not the overall conformance description.
