Association redefinition is a new concept in UML 2.0 that makes it possible to impose additional constraints on some instances of associations. In this paper, we describe how to use association redefinition to declare additional referential integrity and cardinality constraints for associations. We also analyze the interactions between taxonomic constraints and association redefinitions and their impact on the satisfaction of taxonomic constraints. Finally, we establish several conditions that are necessary to guarantee well-formed association redefinitions.
