Dieser Beitrag enthält die wesentlichen konzeptionellen Überlegungen zur Entwicklung eines flexiblen Workflow-Management-Systems. Ausgehend von einer Diskussion möglicher Modellierungsalternativen wird unter Verwendung objektorientierter Modellierungstechniken ein Workflow-Meta-Schema entwickelt, das die relevanten Entitäten klassifiziert und ihre Beziehungen abbildet. Anhand eines Beispiels werden die getroffenen Entwurfentscheidungen ausführlich begründet. Schließlich werden Zustände und Zustandsübergänge von Workflow-Instanzen beschrieben, und es wird diskutiert, wie dynamische Veränderungen

For realizing an exhaustive Service Oriented Architecture, some basic research is still necessary and a consensus has to be reached about key aspects. We argue that one key aspect is a common (meta-) model of enriched service descriptions, especially for all use cases related to service discovery and service selection. A first step towards enriched service description is modelling the service's properties , also known as Quality of Services (QoS). The envisioned service properties are often subsumed either under Quality of Services (QoS) or non-functional properties. Since these terms are used with controversial meanings, they will be discussed here shortly. Functional properties describe what the service does and non-functional properties describe how the service does it. The first step towards using a service is requesting the se...

Information technology is the core enabler for global businesses and integrated, virtual enterprises that achieve common business goals. This integra-tion can be supported or even automated and service-oriented computing offers a promising approach to achieve these goals. This paper argues that a key aspect is publishing standardized services descriptions in a formal, computer-readable way. Furthermore, the paper introduces a model for enriched service description allowing to characterize services modelling their properties. This model will be related to a general service model and to Service Level Agreements. 1

We argue that a key aspect is a common model for enriched service descriptions, especially for all use cases related to service discovery.

Additionally, properties of services that are beyond technical interface specifications should be modelled, e.g. by including Quality of Service (QoS) properties.
