Method Overview (1/2) Method for automatically updating of traceability relationships in UML models. Rule-based Executed by a system Consists of 3 main steps: 1.Capturing change events 2.Recognizing development activities 3.Maintaining traceability relations

Method overview (2/2) Capturing change events There are 4 elementary change events ADD (adding a new element), DEL (deleting an element) preMOD (property of an element before modification), postMOD (property after modification) Recognizing development activities Change event is put in a cache (the EventCache). The change event consists of several events that describe the change, these events are stored in a rulebase (OpenRules). According to a set of predefined rules (the RuleCatalog) a trigger event is matched to the change event. Maintaining traceability relations

Example Description: A PC configurator (system) is edited to give the capability to select a type of graphics card for a PC build. The old situation was just a yes/no situation.
