      Control-driven coordination programming in shared dataspace 

      Papadopoulos, George Angelos; Arbab, Farhad (1997)
      This paper argues for an alternative way of designing coordination models for parallel and distributed environments based on a complete symmetry between and decoupling of producers and consumers, as well as a clear distinction ...
