Enabling integration and aggregation of context information into WS-BPEL processes

Previously, techniques of Context-Aware Computing were limited only to small scale monolithic applications due to the lack of standardized technologies which could support interoperability of services owned by different organizations. The advancement in Service-Oriented Computing technology allowed autonomous and heterogeneous applications to be exposed as Web Services and interconnected into service compositions exploiting well-agreed interfaces, protocols and message formats. The Web Service Business Process Execution Language (WS-BPEL) is the de-facto standard for composing reusable Web services. To enable handling of context information in applications, context information has to be made available within service compositions; hence, integrated in WS-BPEL processes. Through this means, new innovative context-enriched services can be built and provided using the convergence of context-aware computing and workflow technology. In this diploma thesis, context information provided by the C-CAST Context Management Framework and Google Maps Web services, is integrated into WS-BPEL, and business modelers are supported with the creation of context-based compositions. After surveying some of the current best practice and relevant literature in this area, this thesis presents a solution to this problem based on the Integration Process Pattern work previously done at the Institute of Architecture of Application Systems at the University of Stuttgar

Development of an Extended Product Lifecycle Management through Service Oriented Architecture.

Organised by: Cranfield UniversityThe aim of this work is to define new business opportunities through the concept of Extended Product Lifecycle Management (ExtPLM), analysing its potential implementation within a Service Oriented Architecture. ExtPLM merges the concepts of Extended Product, Avatar and PLM. It aims at allowing a closer interaction between enterprises and their customers, who are integrated in all phases of the life cycle, creating new technical functionalities and services, improving both the practical (e.g. improving usage, improving safety, allowing predictive maintenance) and the emotional side (e.g. extreme customization) of the product.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio

SOA and BPM, a Partnership for Successful Organizations

In order to stay effective and competitive, companies have to be able to adapt themselves to permanent market requirements, to improve constantly their business process, to act as flexible and proactive economic agents. To achieve these goals, the IT systems within the organization have to be standardized and integrated, in order to provide fast and reliable data access to users both inside and outside the company. A proper system architecture for integrating company’s IT assets is a service oriented one. A service-oriented architecture (SOA) is an IT architectural style that allows integration of the company’s business as linked, repeatable tasks called services. A subject closely related to SOA is Business Process Management (BPM), an approach that aims to improve business processes. The paper also presents some aspects of this topic, as well as the relationship between SOA and BPM. They complement each other and help companies improve their business performance.Information Systems, SOA, Web Services, BPM

The MobyDick Project: A Mobile Heterogeneous All-IP Architecture

Proceedings of Advanced Technologies, Applications and Market Strategies for 3G (ATAMS 2001). Cracow, Poland: 17-20 June, 2001.This paper presents the current stage of an IP-based architecture for heterogeneous environments, covering UMTS-like W-CDMA wireless access technology, wireless and wired LANs, that is being developed under the aegis of the IST Moby Dick project. This architecture treats all transmission capabilities as basic physical and data-link layers, and attempts to replace all higher-level tasks by IP-based strategies. The proposed architecture incorporates aspects of mobile-IPv6, fast handover, AAA-control, and Quality of Service. The architecture allows for an optimised control on the radio link layer resources. The Moby dick architecture is currently under refinement for implementation on field trials. The services planned for trials are data transfer and voice-over-IP.Publicad
