Artificial institutions usually consider that the regulation of the behaviour of the agents is expressed by norms that refer to an institutional reality, that is an institutional interpretation of the environment in which the agents are situated. To be applied on real systems, however, artificial institutions need to advance from the theory to the practice. Such step requires to conceive the institutional platform components that are in charge of building the institutional reality used in the normative regulation of the system. Such components must be connectable to the heterogeneous elements composing the environment and must also be able to accommodate the different normative platforms that regulate the system. This paper proposes the architecture of an institutional platform having these features. It is shown also how the proposed institutional platform can be linked to environmental and normative ones.
