Extension: isCommonBinding

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/elementdefinition-isCommonBinding

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG

Whether the binding is used on multiple resources, or only on this resource.

Comment:

Some bindings are defined once internally and used in many places. This extension marks those bindings, to allow for generating the binding information once when generating code. When isCommonBinding is true, bindingName will be the same, and unique (e.g. identify re-uses by looking at bindingName).

Context of Use: Use on Element ID ElementDefinition.binding
