Study on Data Exchanging based on SoftMan

Architecture of data exchanging based on SoftMan has been put forward, and different application systems can exchange data in XML by corresponding adapter SoftMan. Data exchanging flow chart has been given. Query SoftMan, the core of data exchanging, has been represented by query model which is a concept-based rule engine. At last, ontology of petroleum industry has been built, and it can use to explain data items, allow flexibility of physical expression, allow diversity of physical expression, and liberate from requiring every application to use the same terminology. Thus, using the unifying ontology, any two application systems can interoperate seamlessly. Each application system maps to the ontology, rather than to each other
