Objective and subjective approaches to coordination constitute two complementary approaches, which, being both essential in MAS engineering, require to be suitably integrated. In this paper, we (i) observe that a successful integration depends on the models of autonomy and coordination promoted by agent technologies, (ii) suggest that ignoring the two models may hinder agent autonomy, (iii) provide an example of “autonomy-preserving” integration by discussing TuCSoN4Jade.
