IoT Toolkit is an open source reference implementation of an Internet of Things core platform for horizontal interoperability based on the Smart Object API.
The IoT Toolkit implements an event-driven architecture, consisting of self-describing distributed Smart Objects. These Smart Objects are virtual representations of physical objects and the people who own and control said objects along with other data resources, that collectively make up the Internet of Things.
The Smart Object abstraction enables composite IoT applications to be constructed from data and resources of various origins, linked to software agents, which in turn control physical processes, produce outputs, or link to other software agents.
Figure 1 shows how the event-driven web object encapsulation provides distributed graph-structured applications connecting to physical things.
