Type Specific Notes on Common Attributes
Type Specific Additional Attributes
Field | Data type | Purpose | Part of Primary Key | |
rangeConstraint | 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 For example, the following range includes the set of all integers: TYPE 900000000000476001 | Integer| Any descendant of <a href="http://snomed.info/id/900000000000459000" title="900000000000459000 | Attribute type |" class="external-link conf-macro output-inline" rel="nofollow" data-hasbody="false" data-macro-name="concept">

may be used as the type of an attribute range. | YES | NO | |
attributeRule | An Expression Constraint that captures the domain, range and cardinality constraints for the given attribute, rule strength and content type. | YES | NO | |
ruleStrengthId | A subtype of 723573005 | Concept model rule strength| which specifies whether the given rule is mandatory (resulting in an error) or optional (resulting in a warning). | YES | NO | |
contentTypeId | A subtype of 723574004 | Content type| which indicates the type of SNOMED CT content over which this rule applies. | YES | NO |
