Standards status: Trial-use Maturity Level: 2 Responsible: HL7 International / Clinical Decision Support Computable Name: ArtifactAuthor
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1755

An individual or organization primarily involved in the creation and maintenance of the artifact. The author of an artifact is distinct from the publisher to enable access and attribution use cases.

This extension is used to support authoring environments that track authorship for the purposes of access and attribution separate from the publisher. Many systems don't do this, and even ones that do will typically only support it for specific types of artifacts. This extension is defined to support representing artifact metadata on resources that are not already metadata resources that have the author element, but 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 (CodeSystem,ConceptMap,NamingSystem,ValueSet).
