Purpose

An 

Scg expression
ShowPartsterm
ShowFormatinline
111115|MRCM module scope reference set|
 specifies the set of MRCM reference sets that should be applied to the content in each module. Within a SNOMED CT Edition, the MRCM rules applied to the included modules must be consistent, to ensure data integrity within an edition is maintained.

Data Structure

An 

Scg expression
ShowPartsterm
ShowFormatinline
111115|MRCM module scope reference set|
 is structured as shown in the following table.

Field

Datatype

Purpose

Immutable

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

Y

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.

N

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.

N

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.

N

refsetId

SCTID

Identifies the reference set to which this reference set member belongs.
In this case, set to |MRCM module use reference set|

Y

referencedComponentId

SCTID

Identifies the SNOMED CT module to which the given concept model refset is applied.
The value must be a subtype of 900000000000443000 |Module (core metadata concept)| within the metadata hierarchy.

Y

mrcmRuleRefsetId

SCTID

A subtype of |MRCM reference set| that defines the concept model rules that are applied to content in the module identified by referencedComponentId.

Y

Metadata

The following metadata hierarchy supports this reference set:

  • Foundation metadata concept
    • Reference set
      • MRCM reference set
        • MRCM module scope reference set
    • Reference set attribute
      • MRCM rule reference set

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.
