Twin Identifier

Go up to Terms and Definitions

A Twin Identifier identifies a Twin Identity independently of the individual Twin Realizations associated with it.

The Twin Identifier provides a stable reference for Configuration, Test Definitions, Test Executions, comparison, Validation, Evidence, and Traceability involving the logical twin.

A Twin Identifier remains distinct from implementation-specific identifiers such as container identifiers, process identifiers, host names, network addresses, DDS entity identifiers, or identifiers assigned to individual Twin Realizations.

an identifier assigned to a Twin Identity

• [DTE1] U.S. Patent Application US20220237111A1, Twin Node concepts and identifiers shared among Twin Nodes
• DIDO-TE normalization of the source concept

Multiple Twin Realizations associated with the same Twin Identity reference the same Twin Identifier.

A Twin Identifier identifies the logical twin rather than a particular realization of that twin.

The representation, encoding, and implementation mechanism used for a Twin Identifier belong to the applicable logical or physical model rather than to the conceptual definition.

The Twin Identifier T-4711 identifies a logical twin. A virtual Twin Realization and a real-world Twin Realization both reference T-4711 while retaining separate realization identifiers.
