Information Services for Dynamically Assembled Semantic Grids

Abstract. The information management requirements in systems based on Web Service Architecture principles include both the management of large amounts of relatively static services and associated semantic information as well as the management of multiple dynamic regions (sessions or subgrids) where the se-mantic information is changing frequently. We design a hybrid Information Service supporting both the scalability of large amounts of relatively slowly varying data and a high performance rapidly updated Information Service for dynamic regions. We use the two Web Service standards: Universal Descrip-tion, Discovery, and Integration (UDDI) and Web Services Context (WS-Context). We report initial results from a prototype that is applied to sensor and collaboration grids.
