Folgende Extensions werden im Kontext der FHIR Ressource 'Composition' definiert:

Name: ExtensionInformationRecipient (Simplifier Projekt Link)

Canonical: http://fhir.de/StructureDefinition/informationrecipient

Kontext:

expression
Composition

Extension	I		Extension	There are no (further) constraints on this element Element id Extension Short description Optional Extensions Element Definition Optional Extension Element - found in all resources. Data type Extension Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
id		0..1	string	There are no (further) constraints on this element Element id Extension.id Short description Unique id for inter-element referencing Definition Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. Data type string Mappings rim: n/a
extension	I	0..0	Extension	There are no (further) constraints on this element Element id Extension.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
url		1..1	uriFixed Value	Element id Extension.url Short description identifies the meaning of the extension Definition Source of the definition for the extension code - a logical name or a URL. Comments The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. Data type uri Fixed value http://fhir.de/StructureDefinition/informationrecipient Mappings rim: N/A
value[x]		1..1		Element id Extension.value[x] Short description Value of extension Definition Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). Sliced: Unordered, Open, by $this(Type) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
valueReference		1..1	Reference()	Element id Extension.value[x]:valueReference Short description Value of extension Definition Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). Data type Reference() Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A

Hinweise: Bei der Extension handelt es sich um eine Übergangslösung, die für die Transformation von CDA-Dokumenten nach FHIR notwendig ist. In CDA ist die Angabe des Empfängers Bestandteil des Dokumentes und nicht (nur) des Transport-Wrappers um das Dokument herum. Zu beachten ist weiterhin, dass HL7 International in FHIR-13635 plant, eine Standard-Extension für das Element einzuführen. Diese Änderung wurde jedoch zum Zeitpunkt der Veröffentlichung der vorliegenden Spezifikation noch nicht umgesetzt.

Beispiel:

<extension url="http://fhir.de/StructureDefinition/informationrecipient" >
    <valueReference>
        <reference value="Patient/test" />
    </valueReference>
</extension>
