      A discussion of workflow models and process description languages
      is presented. The relationship between data, function and
      coordination aspects of the process is discussed, and a claim is
      made that more than one model view (or representation) is needed
      in order to grasp the complexity of process modeling.
    \par
      The basis of a new model is proposed, showing that more expressive
      models can be built by supporting asynchronous events and batch
      activities, matched by powerfull run-time support.
