[Objective] To solve the data synchronization problem between service provider and data provider existed in the construction process of the Federated Institutional Repository of CAS. [Context] The Federated Institutional Repository of CAS is built on the OAI metadata interoperability interface and provides accurate and effective data to user only if the service provider keeps pace with the data provider. [Methods] This paper extends the OAI interface and implements functions such as resource sets updating, map relation updating, invalid data detection and customizes a new metadata format and operation. [Results] The extended OAI interface can effectively realize the data synchronization of resource collections and items between institutional repositories and support data exchange and sharing of the complicated metadata format. [Conclusions] This method effectively solved the practical problem, and can be referenced by similar systems.
