358 | SNOMED CT Release Format 1 (RF1) Guide July 2012 Note: Field name in SNOMED CT Release Format 1 MapSetSeparator A field in the Cross Map Sets Table that contains a character that acts as a separator between target codes in the Cross Map Targets Table. Note: Field name in SNOMED CT Release Format 1 MapSetType A field in the Cross Map Sets Table that indicates whether the Cross Maps associated with this Cross Map Set are all simple one to one maps or include, one to many and/or choices of alternative maps. Note: Field name in SNOMED CT Release Format 1 MapTargetId A field in the Cross Maps Table, which refers to the TargetId of a row in the Cross Map Targets Table that contains a target scheme mapping for a specified Concept. Note: Field name in SNOMED CT Release Format 1 MemberId A field in the Subset Members Table, which refers to the ComponentId of the Concept, Description or other component that is a member of a specified Subset. Note: Field name in SNOMED CT Release Format 1 MemberStatus A field in the Subset Members Table, which indicates the inclusion, exclusion, priority or order of an identified Subset Member in a specified Subset. Note: Field name in SNOMED CT Release Format 1 Moved elsewhere A Status value applicable to a component that has been moved to another Namespace. Concepts or Descriptions may be moved from an Extension to the International Release, from the International Release to an Extension or between one Extension and another. Moves occur if responsibility for supporting the Concepts changes to another organization . Note: Component status value Navigation link An association between two Concepts that supports Navigation between Concepts. Navigation Links generate a hierarchy which has three distinct differences from the subtype hierarchy defined by | is a | Relationships this hierarchy: Does not contribute to the semantic definitions of Concepts; Specifies a display order Concepts within a set of Concepts linked to a common parent. Navigation Links are distributed as a Navigation Subset. Alternative Navigation Subsets may be specified and applied to vary the navigation hierarchy to meet the needs of particular groups of users. Navigation subset © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
A Subset that specifies sets of Navigation Links between Concepts. Pending move A Status value applicable to a component that is thought to belong in a different Namespace but which is maintained with its current SCTID while awaiting addition to the new Namespace. A new Concept and associated Descriptions may be added with this Status where a missing SNOMED CT Concept is urgently required to support the needs of a particular Extension. Existing Concepts are also given this status when it is recognized that they should be moved to a different Extension or to the International Release. See also Moved elsewhere. Note: Component status value. Realm concept subset A Subset of Concepts applicable to a particular Realm. Realm description subset A Subset of Descriptions applicable to a particular Realm. Realm relationship subset A Subset of Relationships applicable to a particular Realm (for future use). RealmId A field in the Subsets Table that identifies the Realm within which the specified Subset is applicable. Note: Field name in SNOMED CT Release Format 1 Reason A field in the Component History Table which provides a text description of the reason for a change in the Status of a component. Note: Field name in SNOMED CT Release Format 1 ReferencedId A field in the References Table that identifies the current component which replaces it or is duplicated by a non-current component. Note: Field name in SNOMED CT Release Format 1 References table A data table consisting of rows each of which represents a Reference between an inactive component and a component that was active for the release in which the first was made inactive. The References Table is part of the History Mechanism. Note: Component Table name in SNOMED CT Release Format 1 ReferenceType A field in the References Table that indicates whether a specified non-current component was replaced by, duplicated by, similar to or an alternative form of the referenced current component.
