Nexus EMR profile for the Observation resource, based on CA-Core. Represents measurements, tests, and simple assertions originating from source EMRs for aggregation.
TypedFhir API / TypeScript
The typed accessor surface Observation exposes for Observation — generated from this IG's compiled profile; each typed accessor has a validating raw-FHIR twin (xRaw) where marked. The three ports are parity-enforced.
