Radio Frequency Identification (RFID) is a promising technology for automated non-line-of-sight object identification. Traditional research of RFID middleware does not concern the business definition of RFID event and related integration with enterprise application system. Considering the requirement of logistics tracking and tracing service based on RFID technology, RFID semantic events which based on XML elements are used to describe the status and information of product logistics. In order to consistent with different business types, the classification and element definition of the RFID events are designed. Through using buffered priority queue, RFID complex events are processed simultaneously and scheduled in real time. An integration framework of RFID events with ERP system is put forward. Different business documents from ERP system can be parsed and generated into uniform XML files and then converted into objects. As a result, RFID complex event is used to control business workflow and provides the warning signal of operation errors. Finally, the RFID-based traceability of product is realized through different query methods.
