StructureDefinition-UKCore-OperationOutcome

Defines the UK Core constraints and extensions on the OperationOutcome resource for the minimal set of data to query and retrieve information about the outcome of an attempted system operation.

Profile Purpose

The purpose of this profile is to provide detailed information about the outcome of an attempted system operation. Operation outcomes are sets of error, warning and information messages provided as a direct system response, or part of one, and provide information about the outcome of the operation.
