TADL - An architecture description language for trustworthy component-based systems

Abstract

Existing architecture description languages mainly support the specification of the structural elements of the system under design with either only a limited support or no support to specify non-functional requirements. In a component-based development of trustworthy systems, the trustworthiness properties must be specified at the architectural level. Analysis techniques should be available to verify the trustworthiness properties early at design time. Towards this goal we present in this paper a meta-architecture and TADL, a new architecture description language suited for describing the architecture of trustworthy component-based systems. The TADL is a uniform language for specifying the structural, functional, and nonfunctional requirements of component-based systems. It also provides a uniform source for analyzing the different trustworthiness properties. © 2008 Springer-Verlag Berlin Heidelberg.
