Purpose

The  | Map correlation and origin type reference set|  is used to meet the requirements for representation of maps between codes in another code system  (other-codes) and a  SNOMED CT concept where the following requirements apply.

  1. A requirement to indicate the degree of correlation between the SNOMED CT concept and the other-codes.
  2. A requirement to indicate whether a concept or code was added to either code system as a result of the mapping process and, in this case, to indicate in which code system the concept or code originated.
  3. A requirement to represent the SNOMED CT attribute to which the  other-code should be applied in order to capture the full specificity of the value represented by the  other-code.
  4. No requirements for mapping rules or advice to be included with each map.

Data Structure

Field

Data type

Purpose

Part of Primary Key

id

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 active (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 memberbecame the current version.

The current version of this reference set memberat 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 memberas at the specified effectiveTime .

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

YES

NO

moduleId

SCTID

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

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

YES

NO

refsetId

SCTID

Identifies the reference setto which this reference set memberbelongs.

In this case, set to as subtype descendant of: | Map correlation and origin type reference set (foundation metadata concept)|

NONO

referencedComponentId

SCTID

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

NONO

mapTarget

The other-code to/from which the concept is mapped.

NONO

A reference to the SNOMED CT concept representing the attribute to which the referencedComponentId (other-code) applies. In some cases, other-codes may be overloaded with a meaning that combines the meaning of a specific attribute with a value applied to it in the SNOMED CT concept model

1

, in these cases accurate mapping needs to specify both aspects of the meaning. The attributeId provides effective disambiguation in these cases. Values of attributeId are restricted to subtypes of | Concept model attribute| .

YESNO
YESNO

Indication of whether the concept was initially in one of the terminologies (SNOMED CT or other-codes) and added to the other as part of mapping or was in both terminologies at the outset. Values are subtypes of   705116007 | Original code system source for linked content value| .

YESNO
