Triggering and data collection framework for sensing application level events

In this paper we propose an interface between the various automatic identification devices and the filtering and collection role proposed by the EPCglobal architecture. This interface, namely the read cycle report interface, acts as a generic abstraction layer for all readers, fixed and mobile, imposing a unified approach for communicating data to an ALE server. Moreover, it enables external applications to associate the start or stop of an event cycle with an actual statement occurring in the physical world such as the press of a submit button on a web page, or the scan of a barcode on a printed label or the crossing of a container from a laser beam.
