We sketch the main software components developed in the project RichWPS, which aims to support end users (no IT experts) to make better use of distributed geodata processing through the OGC Web Processing Service (WPS). These services include a service orchestration solution (modelling GUI and orchestration engine), several supporting modules and services (like a semantics-enabled service regis...

Trends from both within and without public librarianship create new opportunities for libraries to serve the public’s interest in heritage information. Based on a workshop series in Illinois, this article presents exploratory findings on existing public library heritage services and how cyberorganizing can enhance these services. Public libraries offer heterogeneous heritage services in local c...

Business applications composed of heterogeneous distributed components or Web services need mediation to resolve data and process mismatches at runtime. This paper describes mediation in IRS-III, a framework and platform for developing WSMO-based Semantic Web Services. We present our approach to mediation within Semantic Web Services and highlight the role of WSMO mediator types when solving mi...

Designing and controlling cooperative applications composed from e-Services poses new and complex research problems. In the present paper, a model for specifying cooperative applications based on e-Services is proposed, which allows representing both statical and dynamic aspects of cooperating e-Services, and orchestration specifications in a dynamically evolving distributed environment. The ch...

Software as a Service (SaaS) has become the new paradigm in software development. Ecosystems of Web Services can be flexibly and dynamically composed to suit user specific needs. Quality is essential to the success of service based applications. The process of service composition has a major impact on the quality of the final product. We propose a dynamic and flexible Quality of Service Composi...

During the past decade service-orientation has become a popular design paradigm, offering anapproach in which services are the functional building blocks. Services are self-containedunits of composition, built to be invoked, composed, and destroyed on (user) demand.Service-oriented systems (SOS) are a collection of services that are developed based onseveral design principles such as: (i) loose...

We outline a methodology for the modular speciication of telephone services within rst-order linear-time temporal logic. Typically, the services ooered by a telephone system consist of a basic service and several optional additional services, such as automatic callback, redirection, etc. We argue informally that temporal logic provides a exible formalism for the speciication of individual servi...

y Abstract This paper studies composed reduction systems: a system of programs built up from the reduction relations of some reduction system, by means of parallel and sequential composition operators. The trace-based compo-sitional semantics of composed reduction systems is considered, and a new graph-representation is introduced as an alternative basis for the study of compositional semantics...

Refactorings are commonly applied to source code to improve its structure and maintainability. Integrated development environments (IDEs) such as Eclipse or NetBeans offer refactoring support for various programming languages. Usually, the developer makes a particular selection in the source code, and chooses to apply one of the refactorings, which is then executed (with suitable pre-condition ...
