| Field | Data type | Purpose | Mutable | PK* |
|---|---|---|---|---|
| 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 effectiveTime. 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 | Time | The inclusive date or time at which this version of the identified reference set member became the current version. Note: In distribution files the effectiveTime should follow the short ISO date format (YYYYMMDD) and should not include the hours, minutes, seconds or timezone indicator. 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 Optional (Snapshot) |
| 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. Note: A module dependency should only be inactivated if it is found to be erroneous. | YES | NO |
| 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. | YES | NO |
| refsetId | SCTID | Identifies the reference set to which this reference set member belongs. In this case, a subtype descendant of: 723604009 |MRCM attribute domain reference set| | NO | NO |
| referencedComponentId | SCTID | A reference to the SNOMED CA reference to the SNOMED CT component to be included in the reference set. A reference to the SNOMED CT attribute concept to which the attribute-domain rule defined by this member applies. | NO | NO |
| domainId | SCTID | A reference to the SNOMED CT concept that identifies the relevant concept domain. | NO | NO |
| grouped | Boolean | Whether or not the given attribute (identified by referencedComponentId) is treated by a Description Logic reasoner as belonging to a relationship group, when applied to a concept in the given domain. If grouped = 1 (true) then the given attribute (identified by referencedComponentId) is treated by a Description Logic reasoner as belonging to a relationship group. If grouped = 0 (false) then the given attribute (identified by referencedComponentId) is treated by a Description Logic reasoner as not belonging to a relationship group. | YES | NO |
| attributeCardinality | String | The number of times the given attribute can be assigned a distinct (non-redundant) value within the definition of each concept or expression. This string can be parsed using the following ABNF rule (together with the subrules defined in the Expression Constraint Language): attributeCardinality = minimum to maximum | YES | NO |
| attributeInGroupCardinality | String | The number of times the given attribute can be assigned a distinct (non-redundant) value within a single relationship group as part of the definition of a concept or expression. This string can be parsed using the following ABNF rule (together with the subrules defined in the Expression Constraint Language): attributeCardinality = minimum to maximum | YES | NO |
| ruleStrengthId | SCTID | 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 | SCTID | A subtype of 723574004 |Content type| which indicates the type of SNOMED CT content over which this rule applies. In many cases, this will be set to 723596005 |All SNOMED CT content| . | YES | NO |
