An extensible EPCIS data model

With the development of RFID technology, RFID based applications are wildly used in various fields, especially in supply chain automation. EPC (Electronic Product Code) Information Service, which takes a basic and key role in EPC network system, has become a hot research spot. How to establish highly efficient and extensible distributed EPCIS repositories is an important problem to be resolved. This paper proposed a data model of EPCIS which enables different enterprises to customize their own EPCIS data. We also designed and implemented a configuration mechanism to extract duplicated information and reduce data volume.
