    url?: UriType

    Evidence.url Element

    FHIR Specification

    • Short: Canonical identifier for this evidence, represented as a URI (globally unique)
    • Definition: An absolute URI that is used to identify this evidence 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 at which an authoritative instance of this evidence is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the evidence is stored on different servers.
    • Comment: Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version. The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions. In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.
    • Requirements: Allows the evidence to be referenced by a single globally unique identifier.
    • FHIR Type: uri
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    identifier?: Identifier[]

    Evidence.identifier Element

    FHIR Specification

    • Short: Additional identifier for the evidence
    • Definition: A formal identifier that is used to identify this evidence when it is represented in other formats, or referenced in a specification, model, design or an instance.
    • Comment: Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this evidence outside of FHIR, where it is not possible to use the logical URI.
    • Requirements: Allows externally provided and/or usable business identifiers to be easily associated with the module.
    • FHIR Type: Identifier
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: true
    version?: StringType

    Evidence.version Element

    FHIR Specification

    • Short: Business version of the evidence
    • Definition: The identifier that is used to identify this version of the evidence when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the evidence 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. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active artifacts.
    • Comment: There may be different evidence instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the evidence with the format [url]|[version].
