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	Designation of a concept's state. Normally is not populated unless the state is retired.	code

This code system http://terminology.hl7.org/CodeSystem/v3-ActRelationshipSubset defines the following codes:

Lvl	Code	Display	Definition	internalId	Not Selectable	status
1	_ParticipationSubset	ParticipationSubset	Used to indicate that the participation is a filtered subset of the total participations of the same type owned by the Act.\r\n\r\nUsed when there is a need to limit the participations to the first, the last, the next or some other filtered subset.	21567	true	active
2	FUTURE	expected future	An occurrence that is scheduled to occur in the future. An Act whose effective time is greater than 'now', where 'now' is the time the instance is authored.	21368		active
3	FUTSUM	future summary	Represents a 'summary' of all acts that are scheduled to occur in the future (whose effective time is greater than 'now' where is the time the instance is authored.). The effectiveTime represents the outer boundary of all occurrences, repeatNumber represents the total number of repetitions, etc.	21379		active
3	LAST	expected last	Restricted to the latest known occurrence that is scheduled to occur. The Act with the highest known effective time.	21378		active
3	NEXT	expected next	Restricted to the nearest recent known occurrence scheduled to occur in the future. The Act with the lowest effective time, still greater than 'now'. ('now' is the time the instance is authored.)	21377		active
2	PAST	previous	An occurrence that occurred or was scheduled to occur in the past. An Act whose effective time is less than 'now'. ('now' is the time the instance is authored.)	21367		active
3	FIRST	first known	Restricted to the earliest known occurrence that occurred or was scheduled to occur in the past. The Act with the lowest effective time. ('now' is the time the instance is authored.)	21373		active
3	PREVSUM	previous summary	Represents a 'summary' of all acts that previously occurred or were scheduled to occur. The effectiveTime represents the outer boundary of all occurrences, repeatNumber represents the total number of repetitions, etc. ('now' is the time the instance is authored.)	21375		active
3	RECENT	most recent	Restricted to the most recent known occurrence that occurred or was scheduled to occur in the past. The Act with the most recent effective time, still less than 'now'. ('now' is the time the instance is authored.)	21374		active
2	SUM	summary	Represents a 'summary' of all acts that have occurred or were scheduled to occur and which are scheduled to occur in the future. The effectiveTime represents the outer boundary of all occurrences, repeatNumber represents the total number of repetitions, etc.	21371		active
1	ActRelationshipExpectedSubset	ActRelationshipExpectedSubset		21376		active
1	ActRelationshipPastSubset	ActRelationshipPastSubset		21372		active
1	MAX	maximum	The occurrence whose value attribute is greater than all other occurrences at the time the instance is created.	21370		active
1	MIN	minimum	The occurrence whose value attribute is less than all other occurrences at the time the instance is created.	21369		active
