Extension: AddressIdentifier - Detailed Descriptions

Page standards status: Trial-use Maturity Level: 1

Definitions for the address-identifier extension.

Guidance on how to interpret the contents of this table can be found here.

1. Extension
Definition

A unique identifier associated with a location address and may be used to look up an address, validate an address, or link to other data relating to an address.

Optional Extension Element - found in all resources.

2. Extension.url

1. Extension
Definition

A unique identifier associated with a location address and may be used to look up an address, validate an address, or link to other data relating to an address.

Optional Extension Element - found in all resources.

Control0..* 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 (: hasValue() or (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
2. Extension.url
Definition

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

Control1..1
Typeuri
XML RepresentationIn the XML format, this property is represented as an attribute.
Summaryfalse
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.au/fhir/StructureDefinition/address-identifier
3. Extension.value[x]
Definition

An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

2. 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.

3. Extension.extension
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.

InvariantsDefined on this element
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())
SlicingThis element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
  • value @ url
4. Extension.url

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