  abstract =     "This paper studies the extension mechanisms of the
                  Unified Modeling Language UML. It introduces a new
                  appproach for defining UML stereotypes and shows its
                  usefulness by considering domain-specific requirements
                  for databases. The stereotypes introduced possess a
                  precise meaning by translating them into expressions
                  formulated in the Object Constraint Language\~OCL. Apart
                  from proposing a general framework for stereotype
                  definition, this work is also one step in the development
                  of a domain-specific requirements language for
                  information systems.",
