A Metamodel Specification Tool Based on Description Logic and XML-DATA

Interoperation of heterogeneous and autonomous information systems has traditionally been hampered by semantic di erences in their data models. With the World Wide Web, the development of cooperative information systems requires new solution to allow interoperation. In this paper, we address the problem by de ning a methodology to help in the building of cooperative information systems. This metho-dology called X-TIME is based on a case-tool that allows to de ne automatically speci c translators between coupled of heterogeneous data models composing the cooperation. This solution allows the dynamic extension of the cooperation to new heterogeneous information systems with a minimum work. It is best suited for World Wide Web environment where the number of heterogeneous databases that want to exchange data is very large.
