JSON and XML are listed as preferred data formats; what is the role of RDF in FHIR's technical foundations?
Answer
RDF (Resource Description Framework) is used for semantic definitions
While JSON and XML are utilized for the general data representation and encapsulation within FHIR Resources, making the data readable by humans and standard libraries, RDF, or Resource Description Framework, plays a specific role concerning semantics. RDF is employed within the standard specifically for defining the semantic meanings attached to the data elements, ensuring that the interpretation of the data is consistent across systems based on established frameworks for describing resources.
