Properties

This code system defines the following properties for its concepts

Code	URI	Type	Description
Specializes		Coding	The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.
Generalizes		Coding	Inverse of Specializes. Only included as a derived relationship.
internalId	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id	code	The internal identifier for the concept in the HL7 Access database repository.
Name:Class	http://terminology.hl7.org/CodeSystem/utg-concept-properties#rim-Class	code	The formal name for the class clone under this code
appliesTo	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-applies-to	string	Haven't a clue!
status	http://hl7.org/fhir/concept-properties#status	code	Designation of a concept's state. Normally is not populated unless the state is retired.
