    The most promising feature of the Web services platform is its ability to form new services by combining the capabilities of existing services, i.e., its compos ability. The existing services may themselves be composed of other services, leading to a hierarchical composition. In a hierarchical composition, providers vary in the visibility they have over the other providers in the composition. For ... View full abstract»

    Businesses are changing rapidly and organizations tend to act worldwide and are increasingly becoming distributed over the continents. As a consequence, distributed software systems have to keep track with rapidly changing markets. Business rules provide support for capturing some knowledge that changes frequently. Current business rule systems manage and execute business rules, however, typically... View full abstract»

    With the increasing popularity of Web services, a number of technologies have emerged that target the integration and composition of Web services as lightweight components. However, a number of problems have been identified in these approaches, for example regarding an overly static integration and lacking support for the modularization of crosscutting concerns. In this paper, we evaluate FuseJ, a... View full abstract»

    Provision of services within a virtual framework for resource sharing across institutional boundaries has become an active research area. Many such services encode access to computational and data resources, comprising single machines to computational clusters. Such services can also be informational, and integrate different resources within an institution. Consequently, we envision a service rich... View full abstract»

    In this paper we describe the implementation of multiversion concurrency control on the generalized search tree (GiST), an index structure introduced by Hellerstein. For large-scale service directories, the need arises for a data storage system capable of handling substantial amounts of multidimensional data efficiently, as well as being able to support queries which are natural to the type of dat...

    As Web services increasingly become important in distributed computing, some of the flaws and limitations of this technology become more and more obvious. One of this flaws is the discovery of Web services through common methods. Research has been pursued in the field of "semantic Web services". This research is driven by the idea, to describe the functionality of Web services as accurately as pos... View full abstract»

    Current Web services approaches have many limitations, especially with description, discovery and integration mechanisms. In this paper we present a novel software architecture called aspect-oriented Web services (AOWS) which addresses these problems. AOWS uses descriptions of cross-cutting concerns between Web services to give more complete descriptions of services, supporting richer dynamic disc... View full abstract»

    Application frameworks are widely used in software engineering to support reuse by capturing the shared architecture among a family of applications. Their role in Web service construction has, however, been mostly ignored. Reuse in general has rather been considered in the context of Web service composition than as a means to use existing implementations to build new services with related function...

    Service-centric systems exist in a very dynamic environment, which requires these systems to adapt at runtime in order to keep fulfilling its QoS requirements to its users. In order to create self-adaptive service-centric systems, developers not only design the service architecture, but need to design the self-adaptability aspects in a structured way. Current service standards and technologies do ... View full abstract»

    We have designed and implemented a framework assisting client-side applications to utilize asynchronous Web services that deliver results by calling back the applications in the context of enterprise security. This framework can support a number of rich features such as the single-request/multiple-response (SRMR) message exchange pattern, resumable clients, intra-enterprise user and terminal mobil...

    In order for e-government to be successful there is a strong requirement for approaches that are based on widely accepted technical standards and formal design methods. In this paper, we describe the architecture of the eMayor platform, a Web services based platform that is built as a holistic service framework for the deployment and delivery of e-government enterprise services for European munici...

    Enterprise digital dashboard (EDD) is an effective tool for executives to get a top level view of their enterprise as well as closely linked partners. Decision makers need to have easy access to data such as total sales per month, inventory status and a number of other key performance indicators (KPI). These business needs are not in sync with the technological challenges such as the presence of d... View full abstract»

    Convergence of information and telecommunication networks leading to integration of voice, data and video services will bring new opportunities for users as well as service providers. With a growing number of services available on the market, dynamic discovery of services, their composition, selection, mediation as well as execution will be required. In this paper we show how voice and data servic... View full abstract»

    The successful progress of the Web services concept demands flexible ways for Web services to cooperate and to jointly fulfill a task that is requested by a client. In some applications, the execution of the task is not completely specified beforehand, but could rather be referred to as "best effort". One example is information searches. A flexible invocation of cooperating Web services might mean... View full abstract»

    WS-coordination and WS-CF provide support for distributed activities that require coordination in an environment of Web services. Both specifications are generic coordination frameworks, not specific for any application. Despite their generic character, up to now only transactional protocols have been defined, which leverage these coordination frameworks. In this work we map a distributed activity...

    Tracking the execution of composite Web services to identify and adjust their specification according to the current features of the environment is a challenging issue. The concept of views, as a dynamic snapshot over this specification according to a given context, is proposed in this paper. A view is used as a support means for tracking the execution progress of composite Web services and deploy... View full abstract»

    Fault management in Web services composed by individual services from multiple suppliers currently relies on a local analysis that does not span across individual services, thus limiting the effectiveness of recovery strategies. We propose to address this limitation of current standards for Web service composition by employing model-based diagnosis to enhance fault analysis. We propose to add diag... View full abstract»

    The goal of Web service effort is to achieve universal interoperability between applications by using Web standards: this emergent technology is a promising way to integrate business applications. A business process can then be seen as a set of Web services that could belong to different companies and interact with each other by sending messages. In that context, neither a global model nor a globa... View full abstract»
