book chapter Gregor Engels author 107 Luuk Groenewegen author Gerti Kappel author 66 department The computer has evolved from the purpose of pure number crunching to supporting the coordinated collaboration between human and/or artificial beings to reach a certain goal. Object-oriented modelling techniques based on the central notions of object interaction and object collaboration should provide the semantic expressivity to model such coordinated collaboration. Based on an investigation of the object-oriented modelling standard UML, however, the weaknesses of the existing modelling concepts are revealed. SOCCA is presented instead, which is an object-oriented specification language supporting the arbitrarily fine-grained synchronisation of processes, i.e., active objects. Based on several examples of the EU rental car system the expressive power of SOCCA is discussed and compared to related approaches.
