Code	URL	Description	Type
Specializes		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.	Coding
Generalizes		Inverse of Specializes. Only included as a derived relationship.	Coding
internalId	http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id	The internal identifier for the concept in the HL7 Access database repository.	code
notSelectable	http://hl7.org/fhir/concept-properties#notSelectable	Indicates that the code is abstract - only intended to be used as a selector for other concepts	boolean
status	http://hl7.org/fhir/concept-properties#status	A property that indicates the status of the concept. One of active, experimental, deprecated, or retired.	code
deprecationDate	http://hl7.org/fhir/concept-properties#deprecationDate	The date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged.	dateTime
synonymCode	http://hl7.org/fhir/concept-properties#synonym	An additional concept code that was also attributed to a concept	code
subsumedBy	http://hl7.org/fhir/concept-properties#parent	The concept code of a parent concept	code
