BY DEFINITION of this pattern it DOES NOT encapsulate processes! [CONVENTION]{SUBJECT-TO-CHANGE} Webel: Convention: [MIGHT CHANGE]: An '@' prefix in a DigitalTwin model indicates a «digital» Block that maps a non-digital «mappable» Block. Related notes (backlinks) [ASSERTION, POLICY]{STRICT} Webel Twin Pattern: A DigitalTwin (even a "process twin" or "finance twin"), always, without exception, BY DEFINITION HERE either directly or indirectly involves at least one existing or anticipated PhysicalEntity (even if only via another DigitalTwin)!
