Error Handling
MRCM Attribute Domain Reference Sets
An MRCM Attribute Domain Reference Set allows attributes to be associated with the domains in which they may be applied. It also allows grouping and cardinality constraints to be specified for each attribute and domain combination. For each attribute-domain rule, the strength of the rule (e.g. Mandatory concept model rule), and the content type over which this rule applies (e.g. All SNOMED CT content) is also specified.
MRCM Attribute Domain type Reference Set member properties:
Property
Description
Referenced component
A reference to the SNOMED CT attribute concept to which the attribute-domain rule defined by this member applies
Domain
A reference to the SNOMED CT concept that identifies the relevant concept domain
Grouped
Whether or not the referenced attribute is treated by a Description Logic reasoner as belonging to a relationship group, when applied to a concept in the given domain.
  • grouped = 1 (true): attribute is treated by a Description Logic reasoner as belonging to a relationship group.
  • grouped = 0 (false): attribute is treated by a Description Logic reasoner as not belonging to a relationship group.
Attribute cardinality
The number of times the given attribute can be assigned a (non-redundant) value within the definition of each concept or expression
Attribute cardinality in group
The number of times the given attribute can be assigned a (non-redundant) value within a single relationship group as part of the definition of a concept or expression
Rule strength
Whether the given rule is mandatory (resulting in an error) or optional (resulting in a warning)
Content type
The type of SNOMED CT content over which this rule applies
