A Step Forward in Semi-automatic Metamodel Matching: Algorithms and Tool

In recent years the complexity of producing softwares systems has increased due the continuous evolution of the requirements, the creation of new technologies and integration with legacy system,;. When complexity increases the phases of software development, maintenance and evolution become more difficult to deal with, i.e. they became more subject to error-prone factors. Recently, Model Driven Architecture (MDA) has made the management of this complexity possible thanks to models and the transformation of Platform-Independent Model (PIM) in Platform-Specific Models (PSM). However, the manual creation of transformation definitions is a programming activity which is error-prone because it is a manual task. In the MDA context, the solution is to provide semiautomatic creation of a mapping specification that can be used to generate transformation definitions in a specific transformation language. In this paper, we present in algorithm to match metamodels and enhancements in the MT4MDE and SAMT4MDE tool in order to implement this matching algorithm.
