RFID Middleware
RFID Middleware
Software that bridges RFID hardware and enterprise applications. It is the primary means of data gathering for any RFID deployment.
RFID middleware assists with the filtering, aggregation, and routing of RFID data. The middleware has built-in business rules that monitor the data stream and direct data to appropriate enterprise systems.

The goal of the Groovy RFID project is to use Groovy scripting with the Sun Java System RFID middleware to intelligently manage sensors, RFID, strobes, alarms and Sunspot Java motes.
The demo task is to control access to valuables. A human sensor determines if a person is in the room. A badge reader determines if the person is authenticated. An RFID reader tracks what valuables are present. And Sunspots determine if the valuables are moving or if their containers are being opened.
Groovy is integrated into the RFID network controller to provide developers with a simple, but powerful, scripting facility to control sensing, triggering and other interactions. RFID tag reading can be initiated and the resulting events caught by Groovy. Sensor data can be read and physical responses actuated.
The Sun Java System RFID Software is used as the baseline platform, It already has many of the attributes needed to generalize tag reading to managing transducers. It is architected for streaming data values. It has built-in filtering and triggering mechanisms. It has a "adapter" layer for integrating new devices. And finally, it treats both RFID Readers and sensor devices as nodes on the net to be discovered, provisioned and managed.
