In this paper we describe an approach for integrating CR-Prolog and constraint programming, in which CR-Prolog is viewed as a specification language for constraint satisfaction problems. Differently from other methods of integrating ASP and constraint programming, our approach has the advantage of allowing the use of off-the-shelf, unmodified ASP solvers and constraint solvers, and of global constraints, which substantially increases practical applicability.
