Recent peer-to-peer architectures do not fulfill the idea of a service-oriented architecture to allow the flexible composition of services towards concrete applications. This can be justified by the absence of flexible notations for the composition of services that incorporate the dynamic nature exposed by peer-to-peer architectures. In this work, the peer-to-peer architecture DeEvolve is prese...

For quite a long time already, great importance has been attached to the concept of Service-Oriented Architectures for future IT-architectures. However, a major challenge in implementing this concept lies in the gap between the functional department and IT department. Mashups, an architecture also based on services, try to avoid this gap by letting the user himself integrate the services. The f...

An emergent domain that raises some unique engineering challenges is that of software architectures to convert large bodies of unstructured data to human-usable knowledge, such as in the domain of socio-cultural information analysis. We report on an architecture based on Service-Oriented Architectures that we are applying in this domain. We list the requirements that such an architecture must s...

The material presented in this paper is focused on the characteristics of open computational systems and, in particular, the issue of coordinating behavior in such systems, i.e. systemic coordination. Firstly, we introduce a conceptual framework for characterizing systemic coordination at different levels abstraction. Secondly, challenges and opportunities of this framework is outlined as a mat...

From a labour-intensive and paper-based door-keeping function Customs control is aiming now towards international trade facilitation in a way that is both efficient and secure. Digitalization of documents and automation of processes plays an important role in this transition. However, the use of modern technology, in particular SOA, is not yet optimal. The research objective of this paper is to...

Service oriented architectures (SOA) herald a new generation of application systems. Whereas current systems were to be chosen and operated as self-contained systems of individual vendors, service oriented architectures allow for integrating application functionality from different sources internal or external to a company according to individual needs within a specific context. Vendors of ERP ...

Leveraging service oriented programming paradigm would significantly affect the way people build software systems. This paper contributes to the above goal proposing a lightweight formal framework capable of capturing the essential components of service-oriented programming paradigm.

The diffusion of service-oriented computing is today heavily influencing many software development and research activities. Despite this, service-oriented computing is a relatively new field, where many aspects still suffer from a lack of standardization. Also, the service-oriented approach is bringing together researchers from different communities or from organizations having developed their ...

Alliances represent a variety of governance contexts, and hence provide a rich empirical setting for studying the value-creation mechanisms of Information Technology (IT). We examine the influence of IT investment and flexible IT infrastructure, through Service Oriented Architecture (SOA), in the effect of alliance activity on firm performance. We find that the marginal contribution of each joi...
