Purpose

An 900000000000480006 $$ Attribute value type reference set $$ allows a value from a specified range to be associated with a component. This type of reference set can be use for a range of purposes where there is a requirement to provide additional information about particular concepts, descriptions or relationships. For example, an 900000000000480006 $$ Attribute value type reference set $$ is used to indicate the reason why a concepts has been inactivated .

Data Structure

A Attribute value reference set is a component reference set used to apply a tagged value to a SNOMED CT component . Its structure is shown in the following table.

Table 26. Attribute value reference set - Data structure
Field	Data type	Purpose
id	UUID	A 128 bit unsigned integer, uniquely identifying this reference set member . Different versions of a reference set member share the same id but have different effectiveTimes. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.
effectiveTime	Time	The inclusive date or time at which this version of the identified reference set member became the current version. The current version of this reference set member at time T is the version with the most recent effectiveTime prior to or equal to time T .
active	Boolean	The state of the identified reference set member as at the specified effectiveTime . If active = 1 (true) the reference set member is part of the current version of the set, if active = 0 (false) the reference set member is not part of the current version of the set.
moduleId	SCTID	Identifies the SNOMED CT module that contains this reference set member as at the specified effectiveTime . The value must be a subtype of 900000000000443000 $$ Module (core metadata concept) $$ within the metadata hierarchy .
refsetId	SCTID	Identifies the reference set to which this reference set member belongs. In this case, set to a subtype of 900000000000480006 $$ Attribute value type reference set $$
referencedComponentId	SCTID	A reference to the SNOMED CT component being tagged with a value.
valueId	SCTID	The tagged value applied to the referencedComponentId. A subtype of 900000000000491004 $$ Attribute value $$ .

Note: The tables above omit the initial four columns of data present in the release file. These follow the standards versioning pattern id, effectiveTime, active, moduleId. Additionally, to aid understanding, the tables above also show the term from one of the descriptions associated with each of the identified concept. The release file only contains the identifier .
