Schema translation is an important problem in the fields of databases and information systems engineering. In current practice, schemas translation problems have been often tackled by means of ad-hoc solutions. However, ad-hoc solutions are very heavy and hard to maintain, and there is still a compelling need for a general solution able to cope, in a uniform way, the large diversity of the various formats and type of information available. The schema translation problem can be simply stated as follows: Given a (source) metaschema MS1, a (source) schema S1 (instance of MS1) and a (target) metaschema MS2, obtain a schema S2 instance of MS2 that suitably corresponds to S1. This report illustrates three examples of the application of the object-oriented based translation approach to fragments of different instances of MOF metaschemas.
