Extension din - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Extension
Definition

The distinct identification code required by §1271.290(c) for a human cell, tissue, or cellular and tissue-based product (HCT/P) regulated as a device - which is a conditional, variable portion of the production identifier (PI) of a Unique device Identifier (UDI). If the content is from an ICCBBA-encoded UDI, the URI to use for the system is: http://hl7.org/fhir/NamingSystem/iccbba-din. GS1 and HIBCC formatted UDIs do not currently convey the DIN element.

*Note to balloters: The Orders and Observations Workgroup has not yet determined whether the Device resource will include Devices of Human (or other) Origin (tissue, blood, etc.) and so the need for Donation Identification number is currently being met through this extension. If it is determined a separate resource is to be used for Devices of Human (or other) Origin (tissue, blood, etc.) then this extension may be deprecated in the future. Feedback on this issue is welcome.

Control0..1 This element is affected by the following invariants: ele-1
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (xpath: @value|f:*|h:div)
ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')]))
Extension.id
Definition

unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Control0..1
Typestring
Extension.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Alternate Namesextensions, 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.

SlicingThis element introduces a set of slices. The slicing rules are:
  • unordered
  • Open
  • discriminators: value:url
Extension.url
Definition

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

Control1..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.

Fixed Valuehttp://hl7.org/fhir/StructureDefinition/device-din
Extension.valueIdentifier
Definition

Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).
