A model for specifying rationale using an architecture description language

摘要: Besides structural and behavioural properties, rationale plays a crucial role in defining the architecture of software system. However, unlike other architectural features, often remains unspecified inaccessible to tools. Existing approaches for recording are not widely adopted. This paper proposes simple model capturing rationales as part an specification attaching them elements architecture. The bi-directional links between enable forward backward traceability. We describe textual description language named Grasp that implements this model, illustrate its capabilities using example.
