Purpose

An 723589008 | MRCM domain reference set|  enumerates the concept domains to which SNOMED CT attributes may be applied, and provides additional information to support these concept domains.

Each concept domain is uniquely identified by a SNOMED CT concept. When the scope of a domain covers the concepts in a particular hierarchy (or subhierarchy), the supertype concept of this hierarchy (or subhierarchy) is used to identify the domain. When a domain is defined based on membership in a reference set, the associated reference set concept is used to identify the domain. In some situations, a query may be required to define a complex domain. In these cases, the query's expansion reference set (referred to by the 'referencedComponent' of the relevant Query reference set) is used to identify the domain.

For each domain in the SNOMED CT concept model, the  723589008 | MRCM domain reference set|  will contain exactly one member. This reference set member will include an Expression Constraint that defines the concepts in the domain, the identifier of the immediate parent domain (or domains), the domain constraint defined in terms of its proximal primitive concepts and associated mandatory refinements, a generic Domain Expression Template for both precoordinated and postcoordinated content, and a reference to the associated guidance that provides additional human-readable text describing this domain. Please note that it is anticipated that the generic Domain Expression Templates will be specialized further for authoring of specific subdomains using specializations stored in a Template Library.

Reference Set Descriptor and Example Data

Descriptor Template

The table below shows the reference set descriptor for a reference set that follows the  723589008 | MRCM domain reference set|  pattern.

Example Data

The table below shows some example rows from a reference set that uses the format of the  723589008 | MRCM domain reference set|  .

Please note that the generic domain templates defined for the SNOMED CT International Edition are designed to support a proximal primitive parent authoring approach. However, domain templates included in an extension's   723589008 | MRCM domain reference set|   may be designed to support a proximal parent authoring approach if required.
