 +====== Twin Identity ======
  
 +[[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
 +
 +===== Discussion =====
 +
 +A Twin Identity provides the logical identity shared by one or more [[public:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realizations]] representing the same twin.
 +
 +The Twin Identity remains independent of any particular realization, implementation, deployment, process, container, network endpoint, DDS entity, or other realization-specific mechanism.
 +
 +A Twin Identity allows a [[public:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]] or [[public:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]] to refer to the same logical twin when different Twin Realizations participate in the test.
 +
 +The concept derives in part from the U.S. Patent Application description of virtual and physical Twin Nodes that share an identifier and from the DIDO-TE requirement to select between virtual and real-world twin nodes during testing.
 +
 +===== Definition =====

 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-002|[DTE2] Non-Traditional BAA Submission]], F17, //Twin Nodes Selection//
 +  * DIDO-TE normalization of the source concepts
 +
 +===== Note =====
 +
 +A Twin Identity is distinct from the identity of a particular Twin Realization.
 +
 +Changing the selected Twin Realization does not, by itself, change the Twin Identity.
 +
 +A Twin Identity does not prescribe how an implementation represents or transports the identity.
 +
 +===== Example =====
 +
 +A logical twin identified as ''T-4711'' has both a virtual Twin Realization and a real-world Twin Realization. Both realizations participate in the same Twin Identity even though each realization has its own identity and implementation characteristics.
