A profile for representing external application state in Nexus EMR.

TypedFhir API / Pydantic schema

The typed accessor surface Basic exposes for Basic — 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.

The AI-facing shape: from typed_fhir.facade.generated.schemas import BasicSchema — model_json_schema() is a structured-output / tool definition; instantiating validates an extraction. Generated source.
