 +====== Twin Relationship ======
  
 +[[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
 +
 +===== Discussion =====
 +
 +A Twin Relationship establishes the semantic relationship between a [[public:99_annexes:annex-b-terms-and-definitions:t:twin_identity|Twin Identity]] and the [[public:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realizations]] associated with that identity.
 +
 +The Twin Relationship identifies the characteristics, information, and conditions relevant to representing the logical twin across its Twin Realizations.
 +
 +The applicable [[public:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]] specifies the characteristics represented by the relationship and the parameters governing data mapping, source eligibility, source selection, communication, synchronization, and fidelity.
 +
 +A Twin Relationship remains distinct from the communication mechanisms used to exchange information among Twin Realizations. Technologies such as [[public:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] may realize information exchange within the relationship without defining its semantic meaning.
 +
 +===== Definition =====
 +
 +//a semantic relationship between a [[public:99_annexes:annex-b-terms-and-definitions:t:twin_identity|Twin Identity]] and its associated [[public:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realizations]] that identifies the characteristics and conditions represented across those realizations//
 +
 +===== Source =====
 +
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-001|[DTE1] U.S. Patent Application US20220237111A1]], virtual and physical Twin Node concepts and identifiers shared among Twin Nodes
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-002|[DTE2] Non-Traditional BAA Submission]], Digital Twin concepts and F17, //Twin Nodes Selection//
 +  * [[private:07-dido-te:99-annexes:annex-b-references:dte-009|[DTE9] Distributed Immutable Data Object Reference Architecture (DIDO-RA)]], Appendix A, //Digital Twin//
 +  * DIDO-TE normalization of the source concepts
 +
 +===== Note =====
 +
 +A Twin Relationship does not require every available characteristic of a Twin Realization to participate in the relationship.
 +
 +The applicable Configuration identifies the characteristics that participate in a particular Twin Relationship.
 +
 +A communication match, DDS discovery event, Topic match, or Quality of Service match does not, by itself, establish a Twin Relationship.
 +
 +===== Example =====
 +
 +A Twin Identity has a virtual Twin Realization and a real-world Twin Realization. Their Twin Relationship identifies operational state, selected inputs and outputs, and timing behavior as represented characteristics while excluding unrelated implementation details.
