Linked elements in Rational Rhapsody include:
A link module named Rhapsody_links (default name) is added to the Rational DOORS project to describe the links between the shadows. You can control the name of the link module using the RTInterface::DOORS::LinkModuleName property.
The link module describes the links as entry points in a matrix of the shadows. Links can be between shadows in the same module or between shadows from different modules. The blue squares specify a link between the use case "arming and disarming" and sequence diagram "Arming the a..." and between the use case "changing code" to the sequence diagram "Changing the c..."
A link is graphically specified in the Rational DOORS formal module as an arrowhead, red for outgoing links and orange for incoming links.
