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 setcan be used for a range of purposes where there is a requirement to provide additional information about particular concepts, descriptionsor relationships. For example, an 900000000000480006 | Attribute value type reference set| is used to indicate the reason why a conceptshas been inactivated.

Data Structure

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

Field

Data type

Purpose

id (field)

UUID (data type)

A 128 bit unsigned Integer (data type), uniquely identifying this reference set member.

Different versions of a reference set member share the same id (field) but have different effectiveTime (field). This allows a reference set member to be modified or made active (field) (i.e. removed from the active set) at a specified time.

effectiveTime (field)

Time (data type)

The inclusive date or time at which this version of the identified reference set memberbecame the current version.

The current version of this reference set memberat time T is the version with the most recent effectiveTime (field) prior to or equal to time T .

active (field)

Boolean (data type)

The state of the identified reference set memberas at the specified effectiveTime (field) .

If active (field) = 1 (true) the reference set memberis part of the current version of the set, if active (field) = 0 (false) the reference set memberis not part of the current version of the set.

moduleId (field)

SCTID (data type)

Identifies the SNOMED CT modulethat contains this reference set memberas at the specified effectiveTime (field) .

The value must be a subtypeof 900000000000443000 | Module (core metadata concept)| within the metadata hierarchy.

refsetId (field)

SCTID (data type)

Identifies the reference setto which this reference set memberbelongs.

In this case, set to a subtypeof 900000000000480006 | Attribute value type reference set|

referencedComponentId (field)

SCTID (data type)

A reference to the SNOMED CT componentbeing tagged with a value.

valueId (field)

SCTID (data type)

Metadata

The following metadata in the "Foundation metadata concept" hierarchysupports this reference set:

Descriptor template and examples

The tables below show the descriptors that define examples of reference setsthat follow the 900000000000480006 | Attribute value type reference set| pattern.

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