      A core grid ontology for the semantic grid 

      Wei, X.; Dikaiakos, Marios D.; Sakellariou, R. (2006)
      In this paper, we propose a Core Grid Ontology (CGO) that define s fundamental Grid-specific concepts, and the relationships between them. One of the key goals is to make this Core Grid Ontology general enough and easily ...

      Towards a grid information knowledge base 

      Xing, Wei; Dikaiakos, Marios D.; Sakellariou, R. (2007)
      In this paper, we present our work on building a Grid information knowledge base, which is a key component of a semantic Grid information system. A Core Grid Ontology (CGO) is developed for building a Grid knowledge base
