Wares and typologies are grouped into major groups, both geographical and chronological. Within these civilizational groups (Neolithic, Greek-Roman, Middle Ages, Islam, etc.), the wares and typologies are arranged by functional groups (food, non-food), then, for tableware, by major functional groups (consumption, preparation, service, cooking, etc.), and by importance fixed by quality (technical complexity and dissemination areas), without being strict rules, but a framework for reasoning.
In ONICer, few wares and typologies are already integrated and a call for contributions is launched for the Mediterranean basin, the Near and Far East, protohistorical and medieval Europe.
