• Define/document/debug a Test Procedure for RFID product testing • Develop a service-oriented architecture for RFID / warehouse automation including testing automation – Use XML/WSDL messaging over IP – Add/remove devices on XML bus – At UA RFID Center - keep track of pallet/container, equipment, and facility configuration; record results of tests; provide analysis. – Scalable - could plug into warehouse. Open source.

System-Level Agent Architecture

RFID Application -- Reader

RFID Application -- Database

Accomplishments (Summer - Fall 2005) • General-purpose agent architecture developed. • RFID application begun: – Reader Agents (Gen 1) – Database Agent, RFID database schema – GUIs – Test Interface • Fielded for test/use at RFID Center. Rated highly in terms of ease of use and utility; needs richer GUI, Gen2 reader support, minor bugs fixed.

Near-Term Goals (Spring 2006) • Add Gen2 reader support • Improve GUIs; be able to change/delete reader data, company data, test data, etc... • Add support for tag-printer agent • Improve analysis queries and GUI • Enable multiple concurrent instances of application • Fix bugs as they are identified • Performance testing: Where are the edges?

Longer-Term Goals • Tackle scalability issues • Add menu-based natural language interface (MBNLI) for query creation and other logic • Add “intelligence -on-the- fly” capability to agent architecture • Release architecture, RFID application as open-source software
