Radio Frequency IDentification (RFID) technology and Electronic Product Code (EPC) technology have been widely used to identify and keep track of physical objects. EPCglobal proposed the EPC network which consists of several components such as Application Level Events (ALE) and EPC Information Service (EPCIS) to deal with the captured data from different layers. Many studies mostly concentrated on dealing with the RFID tag data in ALE, as well as querying and sharing EPCIS events in EPCIS. However, there is no well-known study on specifying how to generate higher level EPCIS events. The event types and semantic event fields are both uncertain for the capturing application to generate EPCIS events.
