Matching resources is a fundamental problem within large scale distributed environments such as Grid for which the critical process is resource discovery and description. An effective way of solving this problem is providing meta-data about the resources. Ontologies can be used to capture metadata information. Ontologies determine the terms of Grid entities, resources, capabilities and the relationships between them with meaning by the addition of ontological annotations. In this paper we present the initial design of resource description ontology. This ontology can be used for solving resource matching for Grid using semantic web technologies. © 2007 IEEE.
