                         provide interoperability services and dissemination of information 
                         relevant to many branches of computing, many web applications are 
                         based or consume data from other applications. This is a problem 
                         when applications evolve at different speeds and share defined 
                         formats in the message exchanges. This paper presents a study for 
                         the development of an architectural model that allows developments 
                         in the message format used by applications without breaking 
                         interoperability, allowing each to evolve independently. The 
                         solution proposed is to generate from the changes in the contracts 
                         of refactoring scripts XML messages for such messages so that they 
                         follow a model contract or other, making transparent to 
                         applications which involved the contract version the message 
                         receiver expects to receive. The information about the versions 
                         and changes are managed by an intermediary service that 
                         centralizes scripts management functions, data transformation and 
                         delivery of messages. The proposal was evaluated in a study 
                         covering several scenarios, which were evaluated the ability to 
                         generate transformations transparently to applications, the impact 
                         of the use of architecture for applications in lines of code 
                         changes issues and the impact on the performance of the processing 
                         of messages between applications. The main conclusions of this 
                         study, it was revealed that the architecture is able to generate 
                         the necessary transformations for conversion of messages and 
                         transparently to applications that use it, it needs a few 
                         modifications in the applications and is usable when applications 
                         do not require rapid response requests. It is hoped that this 
                         research provide an alternative to solve the problem of different 
                         contract versions transparently to applications, easy to deploy 
                         and is independent of the type of field of applications 
                         involved.",
