Abstract: Radio-Frequency Identification(RFID) middleware turns out to be the right solution for exposing and digesting the information collected by physical infrastructure for enterprise applications, which in practice accelerates the widely-using of RFID technology. This paper introduces an RFID middleware, which supports the EPCglobal Application Level Events(ALE) specification. The engine is composed of four modules, which are kernel module, device management module, event filter module, and configuration module. The engine provides features to encapsulate the applications from device interfaces, processes the raw observations captured by the readers and sensors, and provides an application-level interface for managing readers and querying RFID observations. The functional architecture, design and implementation of the engine are discussed.

Key words: Radio-Frequency Identification(RFID), Application Level Events(ALE), event filter
