Abstract:	This paper presents a multidimensional conceptual Object-Oriented model, its structures, integrity constraints and query operations. It has been developed as an extension of UML core metaclasses to facilitate its usage, as well as to avoid the introduction of completely new concepts. YAM2 allows the representation of several semantically related stars, as well as summarizability and identification constraints.
