Detailed Descriptions

Extension
ShortReference to the image or data source
Definition

Reference to the image or data source.

Cardinality0..*
ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1
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
Extension.id
ShortUnique 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.

Cardinality0..1
Typestring
Mappings
  • rim: n/a
Extension.extension
ShortAdditional content defined by implementations
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.

Cardinality0..*
TypeExtension
Aliasextensions, user content
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.

Slicing

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
Extension.url
Shortidentifies the meaning of the extension
Definition

Source of the definition for the extension code - a logical name or a URL.

Cardinality1..1
Typeuri
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.

Auto Value

Extension.value[x]
ShortReference to the image or data source

media.link R5 Backport extension - An example to illustrate the pre-adopted R5 element via an extension, which is used to link a DocumentReference resource rather than a Media Resource
Extension-UKCore-DiagnosticReportMediaLinkR5-Example

Extension Specific Guidance

With DiagnosticReport.media.link being a mandatory element, the value SHALL be the extension http://hl7.org/fhir/StructureDefinition/data-absent-reason with the valueCode of unsupported. See the example for more details.
