In November 1998 the authors participated in a two-day workshop on the Object Constraint Language (OCL) in Amsterdam. The focus was to clarify issues about the semantics and the use of OCL, and to discuss useful and necessary extensions of OCL. Various topics have been raised and clarified.

Some others will be incorporated in the next version and some of the proposed extensions are elaborated further and published appropriately.     «
