Purpose

Mutable

Part of Primary Key

id

Specref
RefType(data type)
tUUID

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.

N

NO

YES (Full/Snapshot)

effectiveTime

Specref
RefType(data type)
t

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.Y

YES

YES (Full)

Optional (Snapshot) 

active

Specref
RefType(data type)
tBoolean

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.

YES

NO

moduleId

Specref
RefType(data type)
tSCTID

Identifies the SNOMED CT module that contains this reference set member as at the specified effectiveTime.
The value must be a subtype of

Note: The table above omits the initial four columns of data present in the release file. These follow the standard format for id, effectiveTime, active and moduleId. Additionally, to aid understanding, the table above also shows the term from one of the descriptions associated with each of the identified concepts. The release file only includes the identifier of these concepts.
