Extension: objectClass

FHIR Infrastructure Work Group   Maturity Level : 1 Informative Use Context : Any

URL for this extension: 


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

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

A concept that represents a set of ideas, abstractions, or things in the real world that can be identified with explicit boundaries and meaning and whose properties and behavior follow the same rules. It may be either a single concept or a group of associated concepts, abstractions, or things.

Comment :

ObjectClass and Property are treated as a data model that can be mapped to, like any other. This extension merely captures the ObjectClass 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 data type: Element ID ElementDefinition.mapping

usage info: insert a list of places where this extension is used
