چکیده

There exists a need within many large organizations and their partners to operate cross-organizational Web applications. This paper introduces the WebComposition Service Linking System (WSLS), a component-based and serviceoriented system which makes extensive use of Web Services and other standardized Internet technology in order to support development, maintenance and management of reusable and configurable components for cross-organizational Web applications. A real-world application based around the WSLS support system which provides globally accessible core services, NUKATH -Notebook University Karlsruhe(TH) -is introduced. Our NUKATH project’s vision is that business processes of universities shall be established, supported, and provided by aggregations of high-quality, ubiquitously accessible, federated services. These federation-aware services could thence be the basis for reusable and standardized business building blocks of a university. Furthermore, these services could transcend the "business" borders of a university – thus allowing for unique meta-structures of distributed universities supporting new collaboration scenarios in education and research.

Utilizing Abstract WebEngineering Concepts: An Architecture

In this paper we present an open, platform independent, and scalable architecture that implements WebComposition using an object-oriented approach in design and realization and an abstract component model as the platform of development. A web application will be introduced as a set of service components, each providing a closed part of functionality. These service components are designed for re...

Supporting the Evolution of Service Oriented Web Applications using Design Patterns

Web applications make increasingly use of services that are provided by external information systems to deliver advanced functionalities to end users. However, many issues regarding how these services are integrated into web applications and how service oriented web applications evolve, are reengineered and refactored are still addressed in an ad hoc manner. In this paper, we present how design...
