A Calculus for Orchestration of Web Services

Service-oriented computing, an emerging paradigm for distributed computing based on the use of services, is calling for the development of tools and techniques to build safe and trustworthy systems, and to analyse their behaviour. Therefore, many researchers have proposed to use process calculi, a cornerstone of current foundational research on specification and analysis of concurrent, reactive, and distributed systems. In this paper, we follow this approach and introduce CWS, a process calculus expressly designed for specifying and combining service-oriented applications, while modelling their dynamic behaviour. We show that CWS can model all the phases of the life cycle of service-oriented applications, such as publication, discovery, negotiation, orchestration, deployment, reconfiguration and execution. We illustrate the specification style that CWS supports by means of a large case study from the automotive domain and a number of more specific examples drawn from it

Generic Traces and Constraints, GenTra4CP revisited

The generic trace format GenTra4CP has been defined in 2004 with the goal of becoming a standard trace format for the observation of constraint solvers over finite domains. It has not been used since. This paper defines the concept of generic trace formally, based on simple transformations of traces. It then analyzes, and occasionally corrects, shortcomings of the proposed initial format and shows the interest that a generic tracer may bring to develop portable applications or to standardization efforts, in particular in the field of constraints

Object-oriented GUI design of a modeling environment for logical discrete event systems

Ce mémoire porte sur la conception et l'implémentation d'une partie de l'interface personne-machine orientée objet d'un environnement de modélisation de systèmes réactifs appelé MELODIES (Modeling Environment for LOgical Discrete Event Systems ). Cet environnement permet la conception, l'analyse, la simulation et le contrôle de systèmes à événements discrets. L'architecture de l'interface est basée sur certaines idées empruntées au schéma de conception Model-View-Controller (MVC) et au paradigme JSP Model 2 Architecture . Il en résulte une nette séparation entre l'interface personne-machine, les structures de données ainsi que les fonctions sous-jacentes. L'adoption d'une approche orientée objet, comme celle supportée par VisualAge for Java 4.0, au lieu d'une approche orientée fichier supportée par plusieurs environnements de développement (par exemple JBuilder for Java 3.0) permet une plus grande convivialité et une meilleure organisation des artéfacts de modélisation. Afin de déployer cette interface sur différentes plateformes et d'assurer une rapidité d'exécution, la boîte à outils Qt 3.0 et le langage C++, avec sa librairie STL, ont été utilisés dans l'étape de codification. De plus, XML a été retenu comme langage de représentation de données afin de permettre un déploiement éventuel de MELODIES sur le Web

A verified and optimized Stream X-Machine testing method, with application to cloud service certification

The Stream X-Machine (SXM) testing method provides strong and repeatable guarantees of functional correctness, up to a specification. These qualities make the method attractive for software certification, especially in the domain of brokered cloud services, where arbitrage seeks to substitute functionally equivalent services from alternative providers. However, practical obstacles include: the difficulty in providing a correct specification, the translation of abstract paths into feasible concrete tests, and the large size of generated test suites. We describe a novel SXM verification and testing method, which automatically checks specifications for completeness and determinism, prior to generating complete test suites with full grounding information. Three optimisation steps achieve up to a ten-fold reduction in the size of the test suite, removing infeasible and redundant tests. The method is backed by a set of tools to validate and verify the SXM spec-ification, generate technology-agnostic test suites and ground these in SOAP, REST or rich-client service implementations. The method was initially validated using seven specifications, three cloud platforms and five grounding strategies

State-of-the-art on evolution and reactivity

This report starts by, in Chapter 1, outlining aspects of querying and updating resources on the Web and on the Semantic Web, including the development of query and update languages to be carried out within the Rewerse project. From this outline, it becomes clear that several existing research areas and topics are of interest for this work in Rewerse. In the remainder of this report we further present state of the art surveys in a selection of such areas and topics. More precisely: in Chapter 2 we give an overview of logics for reasoning about state change and updates; Chapter 3 is devoted to briefly describing existing update languages for the Web, and also for updating logic programs; in Chapter 4 event-condition-action rules, both in the context of active database systems and in the context of semistructured data, are surveyed; in Chapter 5 we give an overview of some relevant rule-based agents frameworks

Towards a Generic Framework to Generate Explanatory Traces of Constraint Solving and Rule-Based Reasoning

In this report, we show how to use the Simple Fluent Calculus (SFC) to specify generic tracers, i.e. tracers which produce a generic trace. A generic trace is a trace which can be produced by different implementations of a software component and used independently from the traced component. This approach is used to define a method for extending a java based CHRor platform called CHROME (Constraint Handling Rule Online Model-driven Engine) with an extensible generic tracer. The method includes a tracer specification in SFC, a methodology to extend it, and the way to integrate it with CHROME, resulting in the platform CHROME-REF (for Reasoning Explanation Facilities), which is a constraint solving and rule based reasoning engine with explanatory traces
