EDI is characterized by the possibility of sending/ treating messages between information systems without any human intervention. A large number of translations are needed in order to enable the communication between an enterprise and its suppliers and clients. Therefore , translators and wrappers are used to enable this ta sk. In this paper, we study the message translation and conversion associated with B2B and E-commerce needs . We examine the message translation process and show the problems and lacks of existing solutions. We identi fy the mapping between different messages and define a representative framework to map between different representations. At the end, we suggest the use of semi- automatic transformation tool. This translator diff ers by being easy to use for managers and people with limi ted technical skills. It facilitates the task of defini tion of a large number of translations by using matching techniques between source and target message.
