Purpose
A 446609009 |Simple type reference set| allows a set ofto be specified for inclusion or exclusion for a specified purpose. This type ofrepresents an extensional definition of a subset of SNOMED CT. Thus it can be used to fully enumerate a subset of,or.
See also, which can be used to represent an intensional definition of a subset of SNOMED CT. In an intensional definition, the members of the subset are specified by rules rather than by enumerations (e.g. all subtypes of a specified).

Field | Data type | Purpose |
A 128 bit unsigned Integer (data type), uniquely identifying this. 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. | ||
The inclusive date or time at which this version of the identifiedbecame the current version. The current version of thisat time T is the version with the most recent effectiveTime (field) prior to or equal to time T . | ||
The state of the identifiedas at the specified effectiveTime (field) . If active (field) = 1 (true) theis part of the current version of the set, if active (field) = 0 (false) theis not part of the current version of the set. | ||
Identifies thethat contains thisas at the specified effectiveTime (field) . The value must be aof 900000000000443000 |Module (core metadata concept)| within the metadata. | ||
Identifies theto which thisbelongs. In this case, set to 900000000000456007 |Reference set descriptor| | ||

Note: The table above omits 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 table above also shows thefrom one of theassociated with each of the identified. The release file only contains the.
