A Framework for Model Checking Web Service Compositions Based on BPEL4WS

Abstract

Web service composition is an emerging paradigm for enabling application integration within and across organizational boundaries. Model checking is a promising technique for the verification and validation of software systems. In this paper, we present a model checking framework to specifying and verifying the compositions of Web services workflow based on BPEL4WS(Business Process Execution Language for Web Services). By using annotation layers, a BPEL4WS model can be extended with constraints (properties) information. An underlying BPEL4WS model and one or more constraint annotation layers compose a complete specification of a business process imposed specific constraints. By transforming the annotated BPEL4WS model to an extended TPPN(Timed Predicate Petri-net) model, a business process can be automatically verified and analyzed. The method allows us to add conveniently constraints information to a business process model, and state whether a process satisfies given properties without actual execution based on its specification.

Model Checking Adaptive Multilevel Service Compositions

“…Some research efforts on model checking web services have already been proposed [1,11,21,23]. The most related paper that we are aware of is by Nakajima [20] who introduces a lattice-based security labelling into BPEL in order to detect potential insecure…”

Testing and verification in service‐oriented architecture: a survey

“…Dai et al proposed the use of timed predicate Petri nets with annotated BPEL processes. The proposed annotations are not included in the BPEL itself, but they are introduced in annotation layers.…”

Model Checking Airline Tickets Reservation System Based on BPEL

“…It is fit for verifying operational process of web services composition with composition services model of Petri nets. For example, Guilan Dai [3] present a model checking framework to specifying and verifying the compositions of web services workflow based on BPEL. In this framework, by transforming the annotated BPEL model to an extended Timed Predicate Petri-net model, a business process can be automatically verified and analyzed.…”
