    Currently different sources of information exist for users of waterways like audio guides, catalogs, web sites dedicated to waterway users, CDs, flyers, kiosk-based systems etc. These information sources lack in a number of aspects: (i) it is not possible to provide the user with relevant and up-to-date information based on the current location of the user (ii) they provide no ability to proactively provide relevant information (iii) they provide no transparent support for different end-user devices like PDAs, Laptops, handheld PCs. eureauweb is a service-based system addressing the above limitations by providing support for users of European waterways during all three phases of a trip.

    The service oriented architecture and its implementation by Web services have reached a considerable degree of maturity and also a wide adoption in different application domains. This is true for the R&D as well as for the industrial community. Standards for the description, activation, and combination of Web services have been established; UDDI registries are in place for the management of services, and development environments support the software engineer in the creation of Web services. However, the major benefit of service oriented architectures, the loose coupling of services, is still seldom explored in real world settings. The reason is the heterogeneity on different levels within the service oriented architecture. The heterogeneity problems reach from the semantics of service descriptions to compatibility problems between workflows, which have to be connected via service interfaces. In spite of compatible service signatures, workflows might, for example, not be compatible in their semantics. This talk discusses challenges and solutions for a real .Plug&Play. service infrastructure, i.e. a Web service infrastructure, where integration of new Web services becomes as simple and straightforward as plugging a USB stick into your laptop. To achieve this goal various issues have to be addressed: Semantics of services as a foundation for intelligent service mediation and usage Effective, automatic, and intelligent service discovery taking into account application context Dynamic context-aware composition of services into processes The challenges and approaches for a "Plug& Play" service infrastructure are illustrated with a real world example.

    IPSI-PF. A business process matchmaking engine based on annotated finite state automata

    Success of Web services mainly depends on the availability of tools facilitating usage of technology within the addressed B2B integration problems. One severe problem in loosely coupled systems is service discovery including a sufficient matchmaking definition. The concept for service discovery in web service architecture is UDDI providing limited querying functionality and not being capable to deal with the multiple dimensions of a service, like for example semantic, workflow, or Quality of Service aspects. The IPSI Process Finder (IPSI-PF) realizes service discovery by extending the capabilities of UDDI by matchmaking of service descriptions. The extension is realized such that an integration of additional extensions can be added quite easily.

    Web services have a potential to enhance B2B e-commerce over the internet by allowing companies and organisations to publish their business processes on service directories where potential trading partners can find them. This can give rise to new business paradigms based on ad-hoc trading relations as companies, particularly small to medium scale, can cheaply and flexibly enter into fruitful contracts, e.g., through subcontracting from big companies. More business process support by the web service infrastructure is however needed before such a paradigm change can materialise. The current infrastructure does not provide sufficient support for searching and matching business processes. We believe that such a service is needed and will enable companies and organisations to establish ad-hoc business relations without relying on manually negotiated frame contracts like RosettaNet PIPs. This paper gives a formal semantics to business process matchmaking and an operational de scription for matchmaking. Copyright
