Capacity-Driven Web Services

This paper presents the concepts, definitions, issues, and solutions that revolve around the adoption of capacity-driven Web services. Because of the intrinsic characteristics of these Web services compared to regular, mono-capacity Web services, they are examined in a different way and across four steps denoted by description, discovery, composition, and enactment. Implemented as operations to execute at run-time, the capacities that empower a Web service are selected with respect to requirements put on this Web service such as data quality and network bandwidth. In addition, this paper reports on first the experiments that were conducted to demonstrate the feasibility of capacity-driven Web services, and also the research opportunities that will be pursued in the future

Towards an approach to defining capacity-driven web service

This paper is an overview of how capacity-driven Web services are defined and put into action. Because of the specificities of these Web services compared to regular (i.e., mono-capacity) Web services, the way they are looked into is different and occurs through four steps known as description, discovery, composition, and enactment. A Web service that is empowered with several capacities, that are in fact operations to execute, has to know which capacity out of several it has to choose and then, trigger at run-time. For this purpose, this Web service takes into account the requirements like data and network that are put on each capacity it was empowered with. A feasibility discussion on the implementation of capacity-driven Web services is presented in this paper, as well. © 2009 IEEE

SCA Platform Specifications - Version 2.0

The SCOrWare project aims at building an open source implementation of the Service Component Architecture (SCA) specifications. This implementation is composed of 1) a runtime platform for deploying, executing, and managing SCAbased applications, 2) a set of development tools for modeling, designing, and implementing SCA-based applications, and 3) a set of demonstrators. This document contains the specifications of the SCOrWare runtime platform. Section 1.1 lists the parts of SCA specifications supported by the SCOrWare platform. Section 1.2 gives an overview of the SCOrWare platform, and a summary of next chapters of this document. Section 1.3 lists the main update from the version 1 to the version 2 of this documen

Conception and Development Tools for SCOrWare - Version 2.0

The SCOrWare project objectives are to develop: ● A runtime platform for deploying, executing, and managing SCA based applications. ● A set of development tools for modeling, designing, and implementing SCA based applications. ● A set of demonstrators. This document specifies the set of tools used to design, develop, test, and deploy elements to build a distributed architecture compound of components, services, and business services. These tools are based on standards like MDA (Model Driven Architecture) [1], DSL (Domain Specific Language) [2], SCA (Service Component Architecture), and are build on top of Eclipse. Some of these tools complete currently available tools proposed in the SOA Tools Platform (STP) project [3], and others are specific to the SCOrWare project. Section 1.1 lists existing STP tools, and Section 1.2 gives an overview of the contributions of the developed SCOrWare tools, and a summary of next chapters

User-centric personalisation in next-generation persuasive healthcare systems

National audienceResearch works in both personalization and persuasion systems have drawn significant attention in the discipline of computer science recently. However, they have been treated independently from each other. In the current work, we concentrate only the aspects related to applying persuasion for achieving the goal of becoming active. In other words, we describe how to facilitate the user in adopting an active lifestyle by using persuasive mechanisms

Session mobility of multimedia applications in home networks using UPnP

International audienceWith the increasing demand for multimedia contents and with the increased usage of small hand-held devices, a user in a home network has a number of devices at hand which may offer similar multimedia services but with varying capabilities. The user may choose one device for using a particular multimedia service at one time, and change to another device at another time. The user may, however, continue using the same service and maintain his previous session on the new device without restarting a new session. In this paper1, we describe how UPnP can be used for transferring a multimedia session from a device to another in a home network. The procedure for transfer of session is based on the UPnP Audio Video Architecture. We also describe our prototype implementatio
