Extension: Artifact Identifier

Official URL: http://hl7.org/fhir/StructureDefinition/artifact-identifier				Version: 5.3.0-ballot-tc1
Standards status: Trial-use		Maturity Level: 2	Responsible: HL7 International / Clinical Decision Support	Computable Name: ArtifactIdentifier
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1767

A formal identifier that is used to identify this artifact when it is represented in other formats, or referenced in a specification, model, design or an instance.

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 (ClinicalUseDefinition,ConditionDefinition,ImplementationGuide,MedicationKnowledge,NamingSystem,OperationDefinition,SearchParameter,SubstanceDefinition,SubscriptionTopic,TerminologyCapabilities).
