Component Based System Framework for Dynamic B2B Interaction

Business-to-business (B2B) collaboration is becoming a pivotal way to bring today's enterprises to success in the dynamically changing, e-business environment. Though many business-to-business protocols are developed to support B2B interaction, none are generally accepted. A B2B system should support different B2B protocols dynamically to enable interaction between diverse enterprises. This paper proposes a framework for dynamic B2B interaction. A B2B transaction is divided into the interaction part and business implementation part to support flexible interaction. A component based system framework is proposed,to support the B2B transaction execution. To support. dynamic B2B services, dynamic component composition is required. Service and component notions are combined into a composable service component. The composition architecture is also presented

An Approach to Agent-Based Service Composition and Its Application to Mobile

This paper describes an architecture model for multiagent systems that was developed in the European project LEAP (Lightweight Extensible Agent Platform). Its main feature is a set of generic services that are implemented independently of the agents and can be installed into the agents by the application developer in a flexible way. Moreover, two applications using this architecture model are described that were also developed within the LEAP project. The application domain is the support of mobile, virtual teams for the German automobile club ADAC and for British Telecommunications

Composition and Self-Adaptation of Service-Based Systems with Feature Models

The adoption of mechanisms for reusing software in pervasive systems has not yet become standard practice. This is because the use of pre-existing software requires the selection, composition and adaptation of prefabricated software parts, as well as the management of some complex problems such as guaranteeing high levels of efficiency and safety in critical domains. In addition to the wide variety of services, pervasive systems are composed of many networked heterogeneous devices with embedded software. In this work, we promote the safe reuse of services in service-based systems using two complementary technologies, Service-Oriented Architecture and Software Product Lines. In order to do this, we extend both the service discovery and composition processes defined in the DAMASCo framework, which currently does not deal with the service variability that constitutes pervasive systems. We use feature models to represent the variability and to self-adapt the services during the composition in a safe way taking context changes into consideration. We illustrate our proposal with a case study related to the driving domain of an Intelligent Transportation System, handling the context information of the environment.Work partially supported by the projects TIN2008-05932, TIN2008-01942, TIN2012-35669, TIN2012-34840 and CSD2007-0004 funded by Spanish Ministry of Economy and Competitiveness and FEDER; P09-TIC-05231 and P11-TIC-7659 funded by Andalusian Government; and FP7-317731 funded by EU.

Foundation and empire : a critique of Hardt and Negri

In this article, Thompson complements recent critiques of Hardt and Negri's Empire (see Finn Bowring in Capital and Class, no. 83) using the tools of labour process theory to critique the political economy of Empire, and to note its unfortunate similarities to conventional theories of the knowledge economy

The European external action service: an opportunity to reconcile development and security policies or a new battleground for inter-institutional turf wars?

“There cannot be sustainable development without peace and security, and without development and poverty eradication there will be no sustainable peace”. The commitment to intertwine development and security policies of both the European Union and the Member States has increasingly been put forward in policy documents since the early 2000s. While the security-development nexus seems at first sight obvious and rather unremarkable, it has nonetheless become one of the main trouble spots of inter-institutional coherence in EU external action. The fuzzy boundaries between both policy domains and their impact on the distribution of competences turned the implementation of the nexus into a particularly complex and tense exercise. The rationale behind many of the Lisbon Treaty innovations is to address coherence issues by reducing the potential for conflict to a minimum. This paper focuses on the European External Action Service (EEAS) and analyses to what extent it could contribute to reconciling the distinct policies, strategies and institutional cultures of development cooperation and Common Foreign and Security Policy (CFSP). The new diplomatic service constitutes a functionally autonomous body with considerable policy discretion regarding both CFSP and development cooperation. Moreover, it assembles staff and resources from the Council, the Commission and the Member States that previously stood in sharp competition. Yet, the author argues that this integration has only been partial and without the necessary political will, the EEAS might become a new battleground for continued inter-institutional turf wars and thus undermine the EU’s international credibility

Towards a choreography for IRS-III

In this paper we describe our ongoing work in developing a choreog-raphy for IRS-III. IRS-III is a framework and platform for developing WSMO based semantic web services. Our choreography framework is based on the KADS system-user co-operation model and distinguishes between the direction of messages within a conversation and which actor has the initiative. The im-plementation of the framework is based on message pattern handlers which are triggered whenever an incoming message satisfies pre-defined constraints. Our framework is explained through an extensive example
