Grid Resource Ontology: a Keystone of Semantic Grid Information Service

This work presents a set of ontologies to facilitate the adoption of semantic technologies in Grid middleware and to provide a solid foundation for development of semantic Grid information services. The scope of the proposed ontologies includes a description of Grid resources and functionalities, interrelationship of all Grid components, subsystems and services, definition of administrative and usage policies, etc. The work also presents a set of tools to populate the provided Grid resource ontologies with real-data instance assertions by interrogating a traditional Grid information service and discusses the benefits of such representation of Grid resources.
