This paper presents GODIS (Grid Ontological Directory and Integration System) a comprehensive architecture for resource sharing and discovery in large-scale grids, where nodes integrate local ontologies to expand semantic knowledge of shared grid resources. A peer-to-peer based DHT overlay is used to facilitate the formation of semantic communities on a large scale. Inside communities, ontological knowledge is integrated between nodes, and a DHT overlay is used for knowledge dissemination and discovery. This framework architecture improves interoperability among grid participants and aids efficient resource discovery through an expressive query language.
