This paper introduces the COG (Corporate Ontology Grid) project, an EU project funded under the Information Society Technologies programme. In particular the Integration of the Ontological Modelling Suite (Unicorn system) with Industrial Modelling and EAI Tools is discussed. The COG (Corporate Ontology Grid) project addresses the problem of accessing and communicating data held in heterogeneous data formats scattered across disparate systems. COG demonstrates the tangible value of applying grid technologies to industry and it serves as an enterprise level test-bed for a scientifically and technologically innovative approach. COG is developing both a series of ontologies and an entire Information Grid ontological system capable of interacting with disparate data sources from numerous environments. The expected result of COG is the automated generation of transformation scripts from the ontology and from the mappings by turning the ontologies into an “active thesaurus” capable of making data dynamic.
