A core grid ontology for the semantic grid

In this paper, we propose a Core Grid Ontology (CGO) that defines fundamental Grid-specific concepts, and the re-lationships between them. One of the key goals is to make this Core Grid Ontology general enough and easily extensi-ble to be used by different Grid architectures or Grid mid-dleware, so that the CGO can provide a common basis for representing Grid knowledge about Grid systems, including Grid resources, Grid middleware, services, applications, and Grid users. The Core Grid Ontology is designed and developed based on a general model of Grid infrastructures, and described in the Web Ontology Language OWL. Such an ontology can play an important role in building Grid-related Knowledge bases and in supporting the realization of the Semantic Grid.
