Purpose

An  723563008 |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  723563008 |MRCM module scope reference set| is structured as shown in the following table.

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 inactive (i.e. removed from the active set) at a specified time.

NOYES (Full /Snapshot)

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 .

YES

YES (Full)

Optional (Snapshot) 

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.

YESNO

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.

YESNO

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

NONO

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

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

NONO

mrcmRuleRefsetId

A subtype of 723564002 |MRCM reference set| that defines the concept model rules that are applied to content in the module identified by referencedComponentId.

NO

NO

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.
