After briefly recapitulating the classical lines of the literature on coordination models, we discuss the new lines of research that aim at addressing the coordination of complex systems, then focus on mechanisms and patterns of coordination for self-organising systems. The notions of semantic coordination and self-organising coordination are defined and shortly discussed, then a vision of SOSC (self-organising semantic coordination) is presented, along with some insights over available technologies and possible scenarios for SOSC.
