The importance of traceability in software evolutions was quite established, but despite the effort spent, they are many issues that difficult they effective use. These issues are related to the generating and validating of trace information about the relationships and interdependencies between the real world, the requirements and the software system. This information is often mistrusted since they may have become obsolete due to separate evolution of models and systems. This thesis study the use of the transformational technology in the implementation of a traceability mechanism that automatically obtain trace information by identifying the changes made in consecutive artifact versions and store it as transformations. The main advantages gained with it uses are the elimination of the problems of the lack of trace information updating, the systematization of the trace process and the decrease of the cost to obtain, update and validate trace information. Besides these benefits, the storage of trace information in the form of transformations incorporates a larger knowledge on the accomplished modeling, unlike other mechanisms that only store the artifacts and their static inter- relationships.
