Process Support for Evolving Active Architectures

Abstract

Abstract. Long-lived, architecture-based software systems are increasingly important. Effective process support for these systems depends upon recognising their compositional nature and the active role of their architecture in guiding evolutionary development. Current process approaches have difficulty with run-time architecture changes that are not known a priori, and dealing with extant data during system evolution. This paper describes an approach that deals with these issues. It is based on a process-aware architecture description language (ADL), with explicit compose and decompose constructs, and with a hyper-code representation for dealing with extant data and code. An example is given to illustrate the ease-of-use benefits of this approach.

π-ADL for WS-Composition: A Service-Oriented Architecture Description Language for the Formal Development of Dynamic Web Service Compositions

“…This mapping from BPMN to π-ADL for WS-Composition is defined in terms of a formal transformation language, namely π-ARL [20]. It provides a formal semantics for BPMN 5 in terms of the π-calculus through π-ADL (in a similar way to the one defined in [21] for UML2). Using the method proposed in [31], the business process described in BPMN in Figure 2 is annotated as shown in Figure 3Erreur !…”

“…π-ADL for WS-Composition takes its roots in previous work concerning the use of πcalculus as semantic foundation for architecture description languages [19][2] [15] and business process management languages [30][31] [5].…”
