Summary

Complex Extension: Allows defining the expectations for the Observation entry to allow cross-referencing across extracted resources.

  • fullUrl: string: A fhirpath expression to evaluate to extract the value into the fullUrl property. If no value is evaluated, then the element is not extracted.
  • resourceId: string: A fhirpath expression to evaluate to extract the value into the ifNoneMatch property. If no value is evaluated, then the element is not extracted.
  • ifNoneMatch: string: A fhirpath expression to evaluate to extract the value into the ifNoneMatch property. If no value is evaluated, then the element is not extracted.
  • ifModifiedSince: string: A fhirpath expression to evaluate to extract the value into the ifModifiedSince property. If no value is evaluated, then the element is not extracted.
  • ifMatch: string: A fhirpath expression to evaluate to extract the value into the ifMatch property. If no value is evaluated, then the element is not extracted.
  • ifNoneExist: string: A fhirpath expression to evaluate to extract the value into the ifNoneExist property. If no value is evaluated, then the element is not extracted.
