Repositories are becoming an indispensable element for scientific schools and institutes, because they fulfill and expand the functions of digital libraries, and institutes see the benefits of forming electronic archives. Of particular value are the so-called raw (raw) research data. Repositories provide opportunities for downloading, sharing, distributing and using each other's research (field) data.
