Software Architecture, Architecture Description Language, Architectural Style, UML Profile.
There has been a variety of work arguing that the UML 1.x was not adequate as an Architectural Description Language (ADL). UML 2.x has made a large step towards supporting modelling software architectures, e.g. through the intro duction of modelling constructs for composite structures. But many modelling constructs from ADLs can still not be mapped to the UML in a straightforward way. Important examples are typed connectors and architectural styles. We propose a mapping of of the MidArch modelling approach, which is similar to the well-known ADL Acme, to the UML 2.x and the OCL. The mapping is based on mapping the style/family construct to UML Profiles and the system/con figuration construct to UML Component Diagrams. Archi tectural constraints are directly mapped to OCL constraints. In addition, OCL constraints are used to specialize the ar chitecture modelling constructs of UML 2.x, and thus adapt the UML 2.x to the MidArch modelling approach. We de scribe a case study applying our approach and discuss our experiences.
