				<p>EML is a hybrid, rule-based language for merging homogeneous or heterogeneous models. As a merging language requires all the features of a transformation language (merging model A with an empty model into model B is equivalent to transforming A->B), EML reuses the syntax and semantics of <a href="../etl">ETL</a> and extends it with concepts specific to model merging.</p>
				<p>Before merging can be performed, correspondences between elements of the input models need to be established. This can be achieved using the <a href="../ecl">comparison language</a> of Epsilon (or using Java).
