This Code system is used in the following value sets:

  • ValueSet: Type Restful Interaction (Operations supported by REST at the type or instance level.)
  • ValueSet: System Restful Interaction (Operations supported by REST at the system level.)
  • ValueSet: Audit Event Sub-Type (More detailed code concerning the type of the audit event - defined by DICOM with some additional FHIR, HL7, and other additions.)
  • ValueSet: Interaction Trigger (FHIR RESTful interaction codes used for SubscriptionTopic trigger.)
  • ValueSet: Test Script Operation Code (This value set defines a set of codes that are used to indicate the supported operations of a testing engine or tool.)

The set of interactions defined by the RESTful part of the FHIR specification.

This case-sensitive code system http://hl7.org/fhir/restful-interaction defines the following codes in a Is-A heirarchy:

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
