“…6 The UML2Alloy toolset 7 can be exploited to verify the correctness of UML/OCL models. Khosravi et al [12] establish a transformation from Reo to Alloy. This work has not been completed as yet, as it currently ignores the actual values of data passed through the channels and various performance issues need to be tackled still.…”

Service-based systems can be modeled as stand-alone services coordinated by external connectors. Reo is a channelbased coordination language with well-defined semantics that enables a compositional construction of complex connectors from a set of primitive channels. It has been successfully applied in the area of web service composition specification as well as in business process modeling. In this paper, we present a mapping from Reo to mCRL2, a specification language based on the process algebra ACP, extended with data and time. The mapping enables verification of Reo process models and service compositions using the mCRL2 model checking facilities. The supporting Eclipse Coordination Tools suite provides a user-friendly environment for the modeling and verification process.

“…The states in this transition system consist of pairs Sys, V al with Sys a Reo system term (rst) and V al a function that maps nodes to (possibly infinite) sequences of data items. An rst describes the structure of a Reo connector Conn, including the specific primitives that Conn consists of, while the sequences of data items to which V al maps a node n represent those data items that in some instant already have arrived at n. Supplemented with the maximal progress assertion of Khosravi et al in [43], the sos semantics can model context-sensitive connectors.…”

Over the past decades, coordination languages have emerged for the specification and implementation of interaction protocols for communicating software components. This class of languages includes Reo, a platform for compositional construction of connectors. In recent years, many formalisms for describing the behavior of Reo connectors have emerged. In this paper, we give an overview of all these classes of semantic models. Furthermore, we investigate the expressiveness of two more prominent classes, constraint automata and coloring models, in detail.

“…Khosravi et al [13] establishes a mapping of Reo to Alloy, a lightweight modeling language based on first-order relational logic. To check the correctness of a circuit, the desired properties are expressed in terms of assertions which are closely related to LTL and checked by the Alloy Analyzer.…”

Abstract. The paradigms of service-oriented computing and modeldriven development are becoming of increasing importance in the field of software engineering. According to these paradigms, new systems are composed with added value from existing stand-alone services to support business processes across organizations. Services comprising a system but originating from various sources need to be coordinated. The Reo coordination language is a state-of-the-art tool supported approach to channel-based coordination. Reo introduces various types of channels which can be composed to build complex connectors to represent various behavioral protocols. This makes Reo suitable for the modeling of servicebased business processes. In previous work we presented a framework for model checking data-aware Reo connectors using the mCRL2 toolset. In this paper, we extend this result with a proof of correctness, evaluation of optimization techniques, and support for context-sensitive analysis.
