Abstract: [Purpose/significance] At the important node of IR development entering a stable period and in the transition to the next generation of IR, this paper reviews the construction process, status quo and challenges of institutional repository in China, so as to achieve the purpose of accelerating and deepening the development of IR in China. [Method/process] First, it adopts the empirical research method combining the network survey method and telephone and email survey methods, and takes domestic universities, Chinese Academy of Sciences, Chinese Academy of Agricultural Sciences and other scientific research institutes as the survey object to investigate the development status of the national IR; second, the survey results According to the comparative analysis of the university system, scientific research system and the overall situation, summarize the IR development achievements and problems. [Result/conclusion] Some achievements have been made in IR construction. The number of IR under construction and to be built is increasing, and the resource scale is increasing greatly. However, there are some problems in the development of IR, such as imperfect management policies, excessive access restrictions, unclear intellectual property rights, insufficient openness and low self storage rate.

Abstract: [Objective]This study aims to help an organization automatically download its empolyees’ open access papers from iSwitch, and then import these articles to the institutional repository. [Methods] We first synchronized data from iSwitch through timing task scheduling based on FTP protocol. Second, we parsed files and saved metadata to the database in advance. Some functions, such as import process and data management, as well as audit, were also provided. [Results] Papers could be automatically synchronized from iSwitch and then imported to the institutional repository by the system administrator. We have successfully analyzed and imported more than 60, 000 items from Web of Science. [Limitations] The accuracy and timeliness of the service by iSwitch need to be improved. The data import function of the institutional repository should also be optimized for better services. [Conclusions] The high quality institutional repositories built on iSwitch, which significantly relieve burden of researchers and system administors, should be promoted.
