The core objective of WP6 is to evaluate the CONNECT technologies under realistic situations. To achieve this goal, WP6 concentrated a significant amount of its 4th year effort on the finalization of the implementation of the GMES scenario defined during the 3rd year. The GMES scenario allows the consortium to assess the validity of CONNECT claims and to investigate the exploitation of CONNECT technologies to deal with the integration of real systems. In particular, GMES requires the connection of highly heterogeneous and independently built systems provided by the industry partners. WP6 contributed also in providing mobile collaborative applications and case studies showing the exploitation of CONNECTORs on mobile devices.

The purpose of this deliverable is to clarify the individual actions that take place among different actors of the "Passenger-friendly" scenario, as initially described in the DoW. People, services and Things interact with each other throughout the entire sequence of steps that compose the two distinct, but complementary, scenarios that support this specific use case of the CHOReOS project: "From planning to boarding" and "Bad weather at destination". This document also provides the domain requirements that have been elicited through a detailed requirement analysis of the scenarios. Finally, this deliverable presents a high-level overview of the choreographies that take place in the use case, for both scenarios.

This deliverable specifies the main concepts of the CHOReOS middleware architecture. Starting from the Future Internet (FI) challenges for scalability, heterogeneity, mobility, awareness, and adaptation that have been investigated in prior work done in WP1, we introduce the aforementioned concepts to deal with the requirements derived from the FI challenges. In particular, we propose an extensible and scalable service discovery approach for the organization and discovery of services that relies on multiple service discovery protocols. Moreover, we introduce an extensible and scalable approach, based on the service bus paradigm, for service access that features the integration and adaptation of multiple interaction protocols. Furthermore, we propose solutions that enable the execution of FI service compositions that range from compositions of choreographed services, developed according to the CHOReOS development process, to massive compositions of things. Finally, we detail the Cloud & Grid middleware facilities that support the overall middleware and the choreographies that are built on it, via a unified API that provides access to multiple cloud infrastructures (e.g., Amazon EC2, HP Open Cirrus, private clouds).

This deliverable focuses on the design of the CHOReOS Integrated Development and Runtime Environment, aka CHOReOS IDRE, based on the supporting solutions developed within WP2, WP3 and WP4 during CHOReOS' 1st year. The document provides an overall description of the IDRE components, their respective functionalities and the integration dependencies between them, thereby defining the integration points between the components developed in WP2-3-4.

The task of WP6 is to evaluate the CONNECT technologies under realistic situations. To achieve this goal, WP6 concentrated its effort in the development of a main scenario in the context of the GMES, which required the connection of two very different and independently build systems provided by the industry partners. The first one is a video-surveillance system provided by Thales; the second one, is an implementation of the GSMA Rich Communication Suite provided by DOCOMO. The resulting scenario allows to verify the validity of some of the CONNECT claims and to investigate with the introduction of some of the CONNECT technologies in the context of the integration of real systems. In addition, WP6 started the work of evaluating how the overall CONNECT work cycle can be introduced in the context of industrial prototype development.

Service composition implementation, in a Web and business context, opens many investigation and improvements prospects. The contributions in this thesis are then intended to perform a particularly dynamic and flexible composition, able to take into account multiple non-functional constraints. They revolve around the concepts of active, useful and agile composition.Active composition is able to effectively complement dynamic approaches, in order to improve their capability to adapt to non-functional changes. It relies on a transposition of the late-binding principle to the SSOA context, then able to integrate the current QoS values of services at execution time. Useful composition is linked to our new LCP-net formalism for expressing user preferences. The elicitation of non-functional preferences, established between services QoS properties and their values, will afterward provide a total or almost total order over each candidate services sets, dur- ing service selection. Finally, agile composition is the “sum” of the last two, where we lay the groundwork for global QoS management during processes execution.; La mise en œuvre d’une composition de services, dans le contexte de l’entreprise et du Web, ouvre la perspective de nombreux champs d’investigations et d’améliorations. Les contributions de cette thèse ont alors pour vocation de réaliser une composition particulièrement dynamique, souple, et capable de prendre en compte de multiples contraintes non-fonctionnelles. Elles s’articulent autour des concepts de composition active, utile et agile.La composition active est à même de compléter efficacement les approches dynamiques classiques, pour en améliorer les capacités d’adaptation aux changements non-fonctionnels. Elle repose sur une transposition du principe de liaison tardive au contexte des SSOA, alors disposé pour intégrer la QoS courante des services à l’exécution. La composition utile est liée à notre nouveau formalisme LCP-net pour l’expression de préférences utilisateur. L’élicitation de préférences non- fonctionnelles, établies entre les propriétés de QoS des services et leurs valeurs, permet d’obtenir un ordre total ou quasi total sur chaque ensemble de services candidats lors de leur sélection. Enfin, la composition agile correspond à la “somme” des deux précédentes : il s’agit d’une utilisation habile des préférences utilisateurs LCP-net lors de la liaison tardive des services. Nous y posons aussi les bases d’une gestion de la QoS globale des processus métiers.

International audience; This paper addresses the problem of expressing preferences among non-functional properties of services in a Web service architecture. In such a context, semantic and non-functional annotations are required on service declarations and business process calls to services in order to select the best available service for each invoca-tion. To cope with these multi-criteria decision problems, conditional and unconditional preferences are managed using a new variant of conditional preference networks (CP-nets), taking into account uncertainty related to the preferences to achieve a better satisfaction rate. This variant, called LCP-nets, uses fuzzy linguistic information inside the whole process, from preference elicitation to outcome query computation, a qualitative approach that is more suitable to business process programmers. Indeed, in LCP-nets, preference variables and utilities take linguistic values while conditional preference tables are considered as fuzzy rules which interdependencies may be complex. The expressiveness of the graphical model underlying CP-nets provides for solutions to gather all the preferences under uncertainty and to tackle interdependency problems. LCP-nets are applied to the problem of selecting the best service among a set of offers , given their dynamic non-functional properties. The implementation of LCP-nets is presented step-by-step through a real world example.

This paper presents the work that has been done at Thales Communications France regarding the specification and implementation of a semantic Web service discovery and orchestration platform based on services' functional constraints. The main objective was to increase interoperability in heterogeneous and dynamic SOA systems by putting ontologies at the center of this process. A reference implementation is provided that could easily be extended to accommodate an evolution of the domain or of users requirements. Also, ongoing research at Thales is focused on including non-functional (or extra-functional) constraint handling, like Quality of Service (QoS), to the framework., Ce papier présente le travail effectué à Thales Communications France concernant la spécification et l'implémentation d'une architecture pour la découverte et l'orchestration de services Web sémantiques en fonction de leurs contraintes fonctionnelles. L'objectif principal étant d'améliorer l'interopérabilité des systèmes SOA hétérogènes et dynamiques, la particularité de cette architecture est de placer les ontologies au coeur de ce processus. Une implémentation de référence a été réalisée qui pourra par la suite être étendue pour s'accommoder des évolutions des besoins utilisateurs et du domaine. De plus, des travaux de recherche sont actuellement entrepris pour lui adjoindre le support des contraintes non fonctionnelles (ou extra-fonctionnelles) de qualité de service (QoS).

International audience; This paper presents the work that has been done at Thales Communications France regarding the specification and implementation of a semantic Web Service discovery and orchestration platform as part of the S4ALL ITEA program [13]. The central objective is to increase systems' interoperability and adaptability by adding semantic annotations on service declarations and business processes, in order to capitalize on the information contained in ontologies. The semantic platform was developed using common (semantic) web languages and technologies like the Semantic Annotation for WSDL Language (SAWSDL), BPEL, OWL and the UDDI service registry. The following twofold approach has been undertaken: firstly, specifying a SAWSDL to UDDI structural mapping. Its implementation allows us to publish semantically annotated declarations into a well-known service registry and make discovery queries regarding semantic concepts extracted from ontologies. Secondly, implementing a semantically aware business process execution engine able to conduct reasoning on processes where service requirements are expressed using ontological concepts. It also supports a basic form of data adaptation.
