We propose a definition of continuous time dynamical systems made up of interacting open subsystems. The interconnections of subsystems are coded by directed graphs. Our main result is that the appropriate maps of graphs called graph fibrations give rise to maps of the appropriate dynamical systems and thereby to conserved quantities .
