Semantic-based RFID data management

Abstract

Traditional Radio-Frequency IDentification (RFID) applications have been focused on replacing bar codes in supply chain management. Leveraging a ubiquitous computing architecture, the chapter presents a framework allowing both quick decentralized on-line item discovery and centralized off-line massive business logic analysis, according to needs and requirements of supply chain actors. A semantic-based environment, where tagged objects become resources exposing to an RFID reader not a trivial identification code but a semantic annotation, enables tagged objects to describe themselves on the fly without depending on a centralized infrastructure. On the other hand, facing on data management issues, a proposal is formulated for an effective off-line multidimensional analysis of huge amounts of RFID data generated and stored along the supply chain. © 2011 Springer-Verlag Berlin Heidelberg.
