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 events2. Recognizing development activities3. 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.
