In the last years, social and organizational aspects of agency have become a major issue in multi-agent systems' research. Recent applications of MAS enforce the need of using these aspects in order to ensure some social order within these systems. Tools to control and regulate the overall functioning of the system are needed in order to enforce global laws on the autonomous agents operating in it. This paper presents a normative organization system composed of a normative organization modeling language MOISEInst used to define the normative organization of a MAS, accompanied with SYNAI, a normative organization implementation architecture which is itself regulated with an explicit normative organization specification.
