Patent ID: 7796014

Claim:
A computer readable storage medium carrying one or more sequences of instructions, wherein said instructions, when executed by one or more processors, cause the one or more processors to perform the steps of: reading a metadata-based description of a configuration of an radio frequency identification (RFID) reader by an RFID edge server, wherein the RFID edge server interfaces with a plurality of different RFID readers with native configuration arrangements; generating an interface based on the metadata-based description, wherein each of the different RFID readers with native configuration arrangements uses a different metadata-based description; employing the interface to update the configuration of the RFID reader while simultaneously continuing to receive data from at least one other RFID reader to the RFID edge server, without interruption to the RFID edge server; and employing the interface to display a list of available application level event (ALE) filters for the RFID reader and using the interface to select the ALE filters for the RFID edge server, wherein the interface displays said ALE filters in a filter chain and is used for repositioning of filters in the filter chain.
