Our approach allows describing the static, the dynamic and the behavioral aspect as well as the architectural constraints to be respected during the architecture evolution. We specify, using UML2.0, the static aspect of a software architecture in accordance with an architectural style, the dynamic aspect the graph transformation rules, and the behavioral aspect based also on the UML2.0 notation. These specifications are defined according to the proposed notation integrating UML2.0 and OCL language. Indeed, all constraints, all functional and some structural actions can be expressed using the OCL language. These three aspects offer to the architects an intuitive and complete way to specify the software architecture.enText/Conference Paper1617-5468
