Modelling activities in information systems using the coordination language manifold

textabstractWe argue for the need to use control-based, event-driven and state-defined, coordination models and associated languages in modelling at least some of those activities that constitute the functionality of a modem, open and disttibuted information system. We illustrate our points by using such a coordination model and language and showing by means of suitable examples how it can be used for the above mentioned purpose. We also compare our approach with the (rather few) approaches that as yet exist in this rather new area of information systems, and we discuss our model's advantages over those other approaches
