Extension: objectClass

Context of Use: Use on Element ID ElementDefinition.mapping

Definition

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.
