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
