Extension: Artifact URL

Official URL: http://hl7.org/fhir/StructureDefinition/artifact-url Version: 5.2.0-ballot
Standards status: Trial-use Maturity Level: 2 Responsible: HL7 International / Clinical Decision Support Computable Name: ArtifactUrl
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1745

An absolute URI that is used to identify this artifact when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this artifact is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the artifact is stored on different servers.

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.
