Purpose

An 

Concept
t723592007|MRCM attribute range reference set|
 allows attributes to be associated with a valid value range for a given SNOMED CT content type and rule strength. The range of each attribute is defined using an Expression Constraint. This expression constraint represents the set of concepts (or expressions) , expressions, or concrete values that may be used as the value of the given attribute.

Footnote Macro

If ranges including concrete values (such as integers or strings) are required, the Expression Constraint Language can be extended, as described for rangeConstraint in the Data Structure section on this page.


The 

Concept
t723592007|MRCM attribute range reference set|
 also
ShowFormatinline
also provides a summary of the concept model rule associated with each attribute (including all valid domains and the given range) using an Expression Constraint representation. This attribute rule can be completely auto-generated by combining information from the 
Concept
t723604009|MRCM attribute domain reference set|
 and the 
ShowFormatinline
and the 
Concept
t723592007|MRCM attribute range reference set|
. It is therefore recommended that this constraint is not edited directly, but is instead automatically updated.
. 

Data Structure

An 

Concept
t723592007|MRCM attribute range reference set|
 is structured as shown in the following table.

Field

Data type

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 a subtype of |MRCM domain rule by hierarchy reference set|

Y

referenced ComponentId

SCTID

A reference to the SNOMED CT attribute concept to which the attribute-domain rule defined by this member applies.

Y

rangeConstraint

String

An expression constraint, which defines the set of concepts which may be used as the value of the given attribute (identified by referencedComponentId).
This string can be parsed using the ABNF syntax defined for the Expression Constraint Language [4].

Y

attributeRule

String

An Expression Constraint that captures the domain, range and cardinality constraints for the given attribute, rule strength and content type.
This string can be parsed using the ABNF syntax defined for the Expression Constraint Language [4].

N

ruleStrengthId

SCTID

A subtype of |Concept model rule strength|, which specifies whether the given rule is mandatory (resulting in an error) or optional (resulting in a warning).

N

contentTypeId

SCTID

A subtype of |Content type value|, which indicates the type of SNOMED CT content over which this rule applies. In many cases, this will be set to |All SNOMED CT content|.

N

         Footnote Macro

        Please note that the 
         Concept
        t723574004|Content type|
        ShowFormatinline
         hierarchy is designed using 'universal restriction' logic. The hierarchy may therefore appear to be 'upside down'. However, it was designed in this way because if an MRCM rule applies to 
         Concept
        t723596005|All SNOMED CT content|
        ShowFormatinline
         then it also applies to the Content Types that are a supertype of this - including
