In this paper we focus on the problem of integrating knowledge bases expressed in a description logic. To this end, we propose three basic operations: union, intersection and renaming. First, the semantics of these compositional operations is studied abstracting away from implementation details. Then, we present an implementation of the proposed operations, for knowledge bases expressed in the language ALN extended with recursive definitions of concepts, which transforms compositions of
