    url?: UriType

    GraphDefinition.url Element

    FHIR Specification

    • Short: Canonical identifier for this graph definition, represented as a URI (globally unique)
    • Definition: An absolute URI that is used to identify this graph definition 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 graph definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the graph definition 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 graph definition to be referenced by a single globally unique identifier.
    • FHIR Type: uri
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    identifier?: Identifier[]

    GraphDefinition.identifier Element

    FHIR Specification

    • Short: Additional identifier for the GraphDefinition (business identifier)
    • Definition: A formal identifier that is used to identify this GraphDefinition when it is represented in other formats, or referenced in a specification, model, design or an instance.
    • 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

    GraphDefinition.version Element

    FHIR Specification

    • Short: Business version of the graph definition
    • Definition: The identifier that is used to identify this version of the graph definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the graph definition 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.
    • Comment: There may be different graph definition 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 graph definition with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

    • Definition: Indicates the mechanism used to compare versions to determine which is more current.
    • Comment: If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can't be successfully be determined.

    date?: DateTimeType

    GraphDefinition.date Element

    FHIR Specification

The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the graph definition changes.
    • Comment: The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the graph definition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource. See guidance around (not) making local changes to elements here.
