Simple map with correlation from SNOMED CT type Reference Set

Purpose

A 1193542003 |Simple map with correlation from SNOMED CT type reference set| supports the representation of simple maps from SNOMED CT concepts to values in other code systems. No constraints are put on the number of codes mapped from a single SNOMED CT concept.

Data structure

A 1193542003 |Simple map with correlation from SNOMED CT type reference set| is a String - Component reference set used to represent maps from SNOMED CT concepts to codes in another terminology, classification or code system, with the correlation between these codes. Its structure is shown in the following table.

Simple map with correlation from SNOMED CT type reference set - Data structure

Field

Data type

Purpose

Mutable

PK*

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 effectiveTime. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.

YES (Full /Snapshot)

effectiveTime

Time

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

Note: In distribution files the effectiveTime should follow the short ISO date format (YYYYMMDD) and should not include the hours, minutes, seconds or timezone indicator.

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.

YES

YES (Full)

Optional (Snapshot)

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.

YES

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.

YES

refsetId

SCTID

Identifies the reference set to which this reference set member belongs.

In this case, a subtype descendant of: |Simple map with correlation from SNOMED CT type reference set (foundation metadata concept)|

referencedComponentId

SCTID

A reference to the SNOMED CT component to be included in the reference set.

The SNOMED CT concept that is mapped to the code in the other terminology or code system.

mapTarget

String

The other-code to which the SNOMED CT concept is mapped.

correlationId

SCTID

The correlation between the SNOMED CT concept and the other-code. Possible values are the following subtypes of 1193546000 |Map source to map target correlation (foundation metadata concept)| :

YES

PK* indicates if the attribute is part of the primary key for that file/table.

Metadata

The following metadata hierarchy supports this reference set:

Reference Set Descriptor and Example Data

Notes on the tables used to show descriptors and examples

The reference set example tables on this page have been revised as follows to aid clarity and understanding:

The first four columns which are present in all release files are not shown. The omitted columns (id, effectiveTime, active, moduleId) are used in the same way in all referenced sets to support identification, versioning and packaging. They do not directly affect the specific features of a particular reference set or reference set type.
Reference set columns that contain SNOMED CT identifiers are expanded to show details of the concept or description referenced by that identifier. In some cases, the term is shown in the same column using the expression syntax, in other cases an additional column with a name suffix '_term' has been added. In the standard reference set files only the identifier is present in the column and there is no added column for the term. When using reference sets, the term and other details of the component are looked up from the relevant component release files.
