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, the refsetId is set to a subtype of |MRCM domain reference set|

Y

referenced ComponentId

SCTID

A reference to the SNOMED CT concept that identifies the relevant concept domain.

Y

domainConstraint

String

An expression constraint, which defines the set of concepts included in the given concept domain.

This string can be parsed using the ABNF syntax defined for the Expression Constraint Language.

Y

parentDomain

String

An expression constraint, which represents the set of immediate parent domains.

An immediate parent domain is a domain that is a proper superset of the given domain, and which is not a proper superset of any other parent domain.

N

proximalPrimitive Constraint

String

The domain constraint, as it would be represented for proximal primitive modelling. If the domain concept is sufficiently defined, then its proximal primitive parent will be used instead, while if the domain concept is primitive, then the concept itself is used. Additional constraints on the proximal primitive parent are also included.

The expansion of the given constraint must be further filtered to find those concepts with a definitionStatusId =

.

This string can be parsed using the ABNF syntax defined for the Expression Constraint Language.

N

proximalPrimitive Refinement

String

The template representation of any additional refinements that are required to model in the given domain using proximal primitive modelling. These mandatory refinements reflect the defining relationships of the domain concept, when it is sufficiently defined.

This string can be parsed using the 'refinement' rule in the ABNF syntax defined for the Expression Constraint Language.

N

domainTemplate ForPrecoordination

String

A general template that may be used to author precoordinated content. This template incorporates all of the mandatory attribute domain and range rules rules for precoordinated SNOMED CT content.

This string can be parsed using the ABNF syntax defined for the Expression Constraint Language.

N

domainTemplate ForPostcoordination

String

A general template that may be used to author postcoordinated content. This template incorporates all of the mandatory attribute domain and range rules rules for postcoordinated SNOMED CT content.

This string can be parsed using the Expression Template Language (currently under development).

N

editorialGuide Reference

Uniform Resource Locator

A URL that references a web resource in which the given domain is described in further detail.

This URL uses the following pattern: "http://snomed.org/dom<conceptId>"
