Model Driven Engineering (MDE) is based on the principle of unification. Most of the artifacts used or produced in a software project may be uniformly represented by models conforming to various metamodels. In this paper we show how two independent projects could be bridged to produce additional results. The first one is about discovering models from legacy code and the second one is about measuring various kind of models. Due to the interoperability properties of MDE, the integration of these projects was straightforward and allowed to provide a new generic legacy measurement infrastructure.
