Model-Driven Engineering (MDE) and the Semantic Web are valuable paradigms. This paper sketches how to use a scientific and technical result around MDE in the Semantic Web. The work proposes a mechanism to automatize the evaluation of model matching algorithms. The mechanism involves megamodeling and a Domain Specific Language named AML (AtlanMod Matching Language). AML allows to implement matching algorithms in a straightforward way. We present how to adapt the mechanism to the ontology context, for example, to the Ontology Alignment Evaluation Initiative (OAEI).
