Extension: objectClassProperty

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty

Status: draft. Extension maintained by: Health Level Seven International (Orders and Observations)

A quality common to all members of an object class. A property may be any feature that humans naturally use to distinguish one individual object from another. It is the human perception of a single quality of an object class in the real world. It is conceptual and thus has no particular associated means of representation by which the property can be communicated.

Comment:

ObjectClass and Property are treated as a data model that can be mapped to like any other. This extension merely captures the Property element as a discrete code. The information conveyed here should also be conveyed in human-readable form in the mapping.map element.

Context of Use: Use on Element ID ElementDefinition.mapping
