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 semantic 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 Description, 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.

Information Services for Dynamically Assembled Semantic Grids

Many large semantic systems can be described as Semantic Grids of Semantic Grids with large amounts of relatively static services and associated semantic information combined with multiple dynamic regions (sessions or subgrids) where the semantic information is changing rapidly. 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 UDDI and WS-Context in our system. 1
