A 900000000000496009 |Simple map from SNOMED CT 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 coding schemes supported, the number of codes within a particular scheme mapped to by a single SNOMED CT concept or the number of SNOMED CT concepts mapping to a particular code. However, this type of reference set is usually only appropriate where there is a close "one-to-one" mapping between SNOMED CT concepts and coded values in another code system.
A 900000000000496009 |Simple map from SNOMED CT reference set| is a String Reference Set used to represent maps from SNOMED CT concepts to codes in another terminology, classification or code system. Its structure is shown in the following table.
Table: Simple map from SNOMED CT reference set - Data structure
The following metadata hierarchy supports this reference set:

Sample Content from a Simple Map From SNOMED CT Reference Set
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
NO
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 within the metadata hierarchy.
YES
NO
refsetId
SCTID
Identifies the reference set to which this reference set member belongs.
In this case, a subtype descendant of:
NO
NO
referencedComponentId
SCTID
A reference to the SNOMED CT component to be included in the reference set.
Refers to the SNOMED CT concept from which the mapTarget is mapped (i.e. the map source).
NO
NO
mapTarget
String
The equivalent code in the other terminology, classification or code system, to which the referencedComponentId is mapped.
YES
NO

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 effectiveTime. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.
NO
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.
