Abstract. The vision of the Internet of Things (IoT) based on Smart Objects (SOs) promotes an high-level architectural organization of the future IoT designed around the basic concept of SO. An SO is an au-tonomous, cyberphysical object augmented with sensing/actuation, pro-cessing, storing, and networking capabilities. An important issue in sup-porting future SO-based IoT systems is how to classify SOs. Classifica-tion of SOs is an important activity directly influencing the definition of effective SO discovery services and management systems. In particu-lar, the discovery service is a fundamental middleware component of the IoT as it allows SOs and their users to dynamically discover distributed SOs and, specifically, the services, operations, and data that they pro-vide. This paper aims at proposing a reference taxonomy for SOs that is highly functional for an SO discovery service, and, more generally, for an SO management system. The taxonomy is based on a metadata model that is able to describe all the cyberphysical characteristics (geophysical, functional, and non-functional) of an SO.
