Non-functional property specifications for WRIGHT ADL

Many architecture description languages (ADLs) were proposed for describing structure of software systems in terms of components and connectors. However, specification of non-functional properties is not addressed well in these ADLs, although it is crucial for building quality software architectures. We propose new extensions of WRIGHT ADL with capabilities to specify non-functional properties at the architectural level. They are based on ontological definitions of non-functional properties. To demonstrate their usefulness, we applied them to an e-health example.
