An information integration system provides a uniform query interface to a collection of autonomous and distributed sources, connected to each other thanks to a global mediated schema, called domain ontology. The problem addressed in the paper is how to represent such an ontology into CARIN-ALN, a formalism combining classes and rules. We focus on the choices for representing classes, properties and constraints using the characteristics of the formalism. We also propose a method in two steps for representing a domain ontology in the framework of a mediator. The first step is directed by the formalism and the functionalities of the mediator. The second step is an optimization phase guided by the way functionalities of the mediator are implemented.
