Fecha de publicación: 14/06/2018 Fuente: Wipo "IOT" The present invention relates to a system and a method for authoring virtual things, services, and business processes of a do-it-yourself (DIY)-based IoT which enables a user to operate an IoT device as desired. To this end, the present invention includes a system architecture comprising: a physical layer which is a layer for constructing things related to IoT; a virtual object layer which is a layer for representing the things in the physical layer as virtual objects and managing the virtual objects; a service composition layer for creating service objects by combining two or more virtual objects of the virtual objects in the virtual object layer; and a business process layer which, when each of the service objects is created, forms a process flow desired by a user for one scenario with respect to one service object, and utilizes business process modeling notation in order to perform a join-based model of the service objects.
