The integration of business processes with sensors and smart devices will result in a better alignment of enterprise systems with a physical world. More recently, Business Process Modeling Notation (BPMN) 2.0 has become a standard for the business process modeling. BPMN 2.0 defines the formal semantics of its elements and provides means for its extensibility. Sensors and smart devices are the means enabling further automation in enterprise application. There is a strong need for describing the information about physical devices on the business process level. In this paper, we propose BPMN 2.0 extensions according to the ARIS architecture and Linked Data principles in order to achieve better integration between the physical world and business processes. We introduce business function descriptions augmented with information from physical devices in order to promote business process discovery, analysis and execution.
