TWIN-001c — Identify a Twin Realization

Go to TWIN-001 — Establish Twin Identity

Statement

The DIDO-TE SHALL assign each Twin Realization a unique Twin Realization Identifier.

, virtual and physical Twin Node concepts[DTE2] Non-Traditional BAA Submission, F17, Twin Nodes Selection

Rationale

A Twin Identity identifies the logical twin, while a Twin Realization Identifier distinguishes a particular Twin Realization associated with that Twin Identity.

Separate identification of each Twin Realization allows DIDO-TE to distinguish among virtual, physical, real-world, simulated, or other permitted realizations without treating an implementation-specific resource identifier as the identity of the logical twin.

This distinction supports Configuration, realization selection, state acquisition, comparison, and Traceability.

Applies To

Twin Realization IdentifierTwin Node

Verification

Verification confirms that:

# Each Twin Realization has a Twin Realization Identifier.
# Two distinct Twin Realizations do not have the same Twin Realization Identifier within the applicable identity scope.
# Multiple Twin Realizations associated with one Twin Identity remain individually distinguishable.
# The Twin Realization Identifier remains distinguishable from the [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_identifier|Twin Identifier]].
# A change to an implementation-specific identifier does not, by itself, change the Twin Realization Identifier.

Verification includes inspection of a Twin Identity associated with multiple Twin Realizations.

Traceability

ConOps Relationship

This requirement supports registration, Configuration, selection, observation, and comparison of individual Twin Realizations associated with a Twin Identity.
