Abstract
The purpose of this paper is to propose a theoretical, methodological, and technical framework for the semiotic delimitation and analysis of those systems ofmaterial objects and practices which do not belong primarily to the sphere of signification. For the purposes of this paper, we will call such systems (for example economic, urban, or demographic systems) non-communication systems. By their very nature, the study of such systems does not fall wholly within the domain of semiotics, if we consider this domain as coextensive with the study of cultural attitudes and practices. Thus, these systems differ structurally from communication systems, such as language, literature, and the arts, whose primary function is to be used for communication between members of a society and whose structure is primarily semiotic.
