FHIR Extensions Pack
5.3.0-ballot-tc1 - (September 2025 Ballot) International flag

This page is part of the FHIR Core Extensions Registry (v5.3.0-ballot-tc1: Release 5.3) based on FHIR (HL7® FHIR® Standard) v5.0.0. This version is a pre-release. The current official version is 5.2.0. For a full list of available versions, see the Directory of published versions

Extension: ArtifactVersion

Official URL: http://hl7.org/fhir/StructureDefinition/artifact-version Version: 5.3.0-ballot-tc1
Standards status: Trial-use Maturity Level: 2 Responsible: HL7 International / Clinical Decision Support Computable Name: ArtifactVersion
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1768

The identifier that is used to identify this version of the artifact when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the artifact author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence.

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 (ConditionDefinition,NamingSystem,ObservationDefinition,SpecimenDefinition,SubstanceDefinition,SubscriptionTopic).

Context of Use

This extension may be used on the following element(s)
