Issue 7802: It is unclear what the QoSTransition is actually providing (uml-qos-ft-ftf) Source: BAE SYSTEMS (Mr. Kevin Dockerill, kevin.dockerill@baesystems.com) Nature: Enhancement Severity: Significant Summary: It is unclear what the QoSTransition is actually providing. If the QoSLevel represents a system configuration, then this is drawn as a state diagram. Thus the states represent the system modes or configurations. Consequently, transitions are provided within the state diagram and hence I can't see what additional metaclass elements are providing. If there are reasons for QoSTransition, then it would be useful if an explanation was included Resolution: Revised Text: We popose to extend the last paragraph in page 16 and modify Figure 8.7 QoS Transition: QoS Transition models the allowed transitions between QoS Levels. QoS Level Change is a type of events that can fire a QoS Transition. The architecture and implementation of software elements take into account these states and transitions. The property AdaptionActions includes the set of actions to describe the adaptation to new mode. Figure 8.7 QoSLevel Diagram Actions taken: September 30, 2004: received issue March 8, 2006: closed issue Discussion: We introduce a new attribute in the QoSTransitions to support the description of the set of actions. We do not specify the concrete syntax for language used for the description of these actions.
