Abstract: [Purpose/significance] By investigating the research status and service demand of the new generation knowledge at home and abroad, this paper analyzes the key technologies and functional characteristics of the next generation repositories. It puts forward the key trends of institutional repositories, and provides some suggestions for the development of next generation repositories.[Method/process] Through literature research, this paper summarized the development trend of institutional repository technology and function. Then, it introduced 11 key technologies, standards and protocols of the new generation repositories. By researching and designing the functions, it analyzed the development of next generation repositories in many aspects such as framework, functions and service target.[Result/conclusion] The paper generalizes the development trends of next generation repositories as followings:①from institutional repository to institutional information infrastructure.②from self-archiving to automated submission or ingestion.③ from independent platforms to current research information system(CRIS).④ from scholarly outputs management platform to academic resources service center. ⑤from information retrieval to supporting big data and semantic retrieval. ⑥from academic archives to academic scholarly communities. ⑦from providing metrics and altmetrics services to creating a new system of academic evaluation.
