Concept

 is structured as shown in the following table.

FieldDatatype

Data type

Purpose

Mutable

Part of Primary Key

id

Specref
RefType(data type)
tUUID

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.

NO

YES (Full/Snapshot) 

effectiveTime

Specref
RefType(data type)
tTime

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) 

active

Specref
RefType(data type)
tBoolean

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.

YES

NO

moduleId

Specref
RefType(data type)
tSCTID

Identifies the SNOMED CT module that contains this reference set member as at the specified effectiveTime.

Para filter

The value must be a subtype of

Concept
t900000000000443000|Module|
ShowFormatinline

within the metadata hierarchy.


YES

NO

refsetId

Specref
RefType(data type)
tSCTID

Identifies the reference set to which this reference set member belongs.
In this case, set to a subtype of

Concept
t723592007|MRCM attribute range reference set|

NO

NO

referenced ComponentId

Specref
RefType(data type)
tSCTID

A reference to the SNOMED CT attribute concept to which the range defined by this member applies.

NO

NO

rangeConstraintString

Specref
RefTypedata type
tstring

An expression constraint, which defines the set of concepts that 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 .

If ranges using concrete values are required, the Expression Constraint Language can be extended with the keyword "TYPE", by replacing the simpleExpressionConstraint rule with the following two rules: 

simpleExpressionConstraint  = [constraintOperator ws] eclFocusConcept / typeKeyword ws conceptReference
typeKeyword = ("t"/"T") ("y"/"Y") ("p"/"P") ("e"/"E")

For example, the following range includes the set of all integers:

Concept
t TYPE 900000000000476001 |Integer|
ShowFormatinline

Para filter

Any descendant of

Concept
t900000000000459000 |Attribute type|
ShowFormatinline

may be used as the type of an attribute range.


YES

NO

attributeRuleString

Specref
RefTypedata type
tstring

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 .
If ranges with concrete values are required, the Expression Constraint Language can be extended as described above (for rangeConstraint).

YES

NO

ruleStrengthId

Specref
RefType(data type)
tSCTID

A subtype of

Concept
t723573005|Concept model rule strength|
ShowFormatinline
which specifies whether the given rule is mandatory (resulting in an error) or optional (resulting in a warning).

YES

NO

contentTypeId

Specref
RefType(data type)
tSCTID

A subtype of

Concept
t723574004|Content type|
ShowFormatinline
which indicates the type of SNOMED CT content over which this rule applies.

YES

NO
