Analyzing metadata of Russian open access repositories in science and technology for using in RNPLS&T’s system of Single Open Information Archive

RNPLS&T has been designing and developing the Single Open Infor- mation Archive (SOIA) to integrate all digital full-text resources generated or otherwise acquired by RNPLS&T. SOIA is intended to use not only its own content sources but also metadata collected from other open access repositories, in particular Russian repositories. The goal of this analysis is to draw the list of available sources that meet the following criteria: OAI-PMH provider technical accessibility, continuity (regularity) of updating. The authors present the findings of their analysis and describe the challenges revealed. The list of Russian open accessrepositories is drawn for metadata intended to be used in RNPL&T’s SOIA as extra source of information. The article is prepared within the framework of the State Order No 075-01300-20-00 “Design and development of the system of Open Archive of Integrated Information Library Resources of Russian National Public Library for Science and Technology as a modern system of knowledge management in digital environment: On the way to Open Science” for the years 2020–2022.
