Abstract
In this paper we report on a feasibility study in reengineering legacy systems towards a model-driven architecture (MDA). Steps in our approach consist of (1) parsing the source code of the legacy system according to a grammar; (2) mapping the abstract syntax trees thus obtained to a grammar model that is defined in the Meta-Object Facility (MOF); (3) using model to model (M2M) transformations to turn the grammar model into a generic meta-model, called GenericAST, in which information about software systems can be stored in a language-independent way; (4) mapping the GenericAST models, again using M2M transformations, to UML models that can be either used for code generation or for documentation purposes. The steps have been implemented in a prototype model harvesting tool that is based on ArcStyler, the MDA environment provided by Interactive Objects. Our paper presents this approach, and reports on our experiences in applying the method to a 178 KLOC production system from the insurance domain written in PL/SQL.
