Parameters

Use Name Scope Cardinality Type Binding Documentation

name

1..1

The name of the namespace as used in CQL declarations (e.g. hl7.fhir.uv.cql). For libraries published in FHIR NPM packages, this corresponds to the FHIR NPM packageId (and the packageId element of the ImplementationGuide resource).

OUT

return

1..1

uri

The uri of the namespace with the given name (e.g. http://hl7.org/fhir/uv/cql). For libraries published in FHIR NPM packages, this corresponds to the baseCanonical of the FHIR NPM package.
