Extension: Artifact Version Algorithm

Official URL: http://hl7.org/fhir/StructureDefinition/artifact-versionAlgorithm				Version: 5.3.0-ballot-tc1
Standards status: Draft		Maturity Level: 1	Responsible: HL7 International / Clinical Decision Support	Computable Name: ArtifactVersionAlgorithm
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1738

Indicates the mechanism used to compare versions to determine which is more current.

This extension is defined to support representing artifact metadata on resources that are not already canonical resources that have the corresponding element, and that behave in a definitional way. For example, it would not be appropriate to use this extension on a patient-specific resource such as MedicationRequest or CarePlan. For resources where this element was added in R5, the cross-version extension should be used rather than this extension (ActivityDefinition,CapabilityStatement,CodeSystem,CompartmentDefinition,ConditionDefinition,ConceptMap,ExampleScenario,GraphDefinition,ImplementationGuide,Library,Measure,MessageDefinition,NamingSystem,ObservationDefinition,OperationDefinition,PlanDefinition,Questionnaire,SearchParameter,SpecimenDefinition,SubscriptionTopic,StructureDefinition,StructureMap,TerminologyCapabilities,ValueSet).
