Semantic-based Data Management in RFID assisted Supply Chains

Traditional Radio-Frequency IDentication (RFID) applications have been focused on replacing bar codes in supply chain management. Leveraging a ubiquitous computing architecture, we envision 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 a RFID reader not a trivial identication 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, an effective off-line multidimensional analysis of huge amounts of RFID data generated and stored along the supply chain can be performed.
