A field that provides the unique identifier of a component ( concept, description or relationship) or reference set member .
Note:
The data type of the id for a component is SCTID and this identifier is used to refer to the component .
The data type of the id for a reference set member is UUID. This identifier is only used to support versioning of a rows (member) in a Reference set it does not identify the Reference set itself (see refsetId) nor does it identify to a component refered to by the Reference set (see referencedComponentId).
A field in the RF2 Identifier file containing a SNOMED CT identifier which identifies the alternate code system.
Note: In practice, the identifier file is not used in the SNOMED CT International Release as the use of Simple Map from SNOMED CT Reference Set or Simple Map to SNOMED CT Reference Set is preferred. The only current use of this file is for internal identification during the development process.
The file structure used to distribute alternative Identifiers for SNOMED CT components.
Note: The Identifier file is not currently used in the SNOMED CT International Release as use of the more flexible / structures are preferred for links to/from alternative codes. The only known current use of this file is for internal identification of components during the content development process.
A datatype that represents a whole number.
Note: In SNOMED CT release file specifications integers are represented as a string of decimal digits. The range of values and support for negative values may be constrained for the specification are specified for each usage of this datatype. However, unless otherwise specified, all release file fields of data type integer are assumed to be 32-bit signed integers.
