    First Steps in the Development of a Web Service Framework for Hetero- geneous Environmental Information Systems
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Radetzki, Uwe; Alda, Sascha; Bode, Thomas; Cremers, Armin B.
    In this paper we present our first steps in developing a web service framework for heterogeneous environmental information systems. This framework allows an easy assembly of data and method services which are distributed over the entire web. In the field of web services, two consortia already conduct endeavors to standardize access to data and method of a web service. Besides, several standardization efforts for building distributed systems arise from the field of distributed objects and component technology. Our approach combines and integrates these technologies within one framework and, thus, provides a higher interoperability among all these different standards. The aggregation as well as the interaction among these services is prescribed by a XML-based workflow process engine which is also part of the framework. Another integral part of this framework is the XMT model which allows the integration of incompatible services by means of portable algorithms. We further demonstrate a conceivable application of our framework in a scenario pertaining to disaster management, in particular to the field of fire fighting.

    IRIS: A Framework Supporting Composition and Device-Specific Access of Software Services
    (Sh@ring – EnviroInfo 2004, 2004) Radetzki, Uwe; Mancke, Sebastian; Cremers, Armin B.
    In this paper we present a software platform supporting domain experts in building and maintaining compositions of services (business processes) as well as allowing flexible access to these services with different client devices. We will demonstrate our framework by means of a case study in the area of disaster management. The proposed concepts are currently developed and investigated in the research project Interoperability and Reusability of Internet Services (IRIS).

    Mediatorbasierte ad hoc Integration autonomer Web Services
    (Informatik 2004 – Informatik verbindet – Band 1, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Radetzki, Uwe; Bode, Thomas; Cremers, Armin B.
    Ad hoc Integration autonomer Dienste ist ein wichtiger Bestandteil bei der dynamischen Fusion verteilt vorliegender Daten und Methoden. In diesem Papier stellen wir ein komponentenbasiertes Mediatormodell vor, mit dessen Hilfe wir hoffen, dieser Vision einen entscheidenden Schritt näher zukommen. Das Modell erlaubt die Beschreibung der benötigten Mediatoren und ermöglicht eine effiziente Identifikation und Komposition existierender Funktionalitäten. Die Darstellung der relevanten, semantischen Kontextinformation erfolgt dabei ontologiebasiert.
