RFID-based technology for identification and tracking has potential to cut costs and provide strategic information for real-time decision support. To be useful, the generated data must be linked and distributed through the enterprise and the supply chain. We cannot achieve this kind of integration without effectively modeling the semantics of the data. Deficiencies in existing modeling constructs lead us to introduce a supertype/subtype relationship. We also discuss relational implications.
Keywords: conceptual modeling, typing relationship, supertype, subtype, RFID data
