Semantic tools for workflow construction

Abstract

In this paper we present design and development of a knowledge framework for grid and web service-based workflow composition and execution. We highlight the corresponding architecture and the process of service annotation, discovery and composition in the project KWfGrid [5]. We describe in detail the challenges of a flood-forecasting application and corresponding design and development of the service oriented model, which is based on the well known Web Service Resource Framework (WSRF). Semantic descriptions of the WSRF services are presented as well as the architecture, which exploits semantics in discovery and composition of service workflows. Further, we demonstrate how experience management solutions can aid the process of collaborative service discovery and composition. The whole K-Wf Grid system provides a unique approach in Semantic Grids by combining the advances of semantic web services and grid architectures. © Springer-Verlag Berlin Heidelberg 2006.
