Data repositories are places where research data are stored, preserved and published. Here you can store research data or reuse stored data. Most repositories provide these services free of charge. These data repositories are also a source of information for data search engines. Some disciplines are well ahead of the curve in sharing scientific data and have their own discipline-specific repositories focused on specific data in their field (these include fields related to biology, medical disciplines, astrophysics, earth and environmental sciences, but also many others). Disciplines that do not yet have their own discipline-specific repositories use institutional or general repositories.

Re3data

• https://www.re3data.org/

Re3data is a basic gateway and registry of data repositories where you can search for individual repositories by subject area or keywords. However, in addition to repositories with freely available data, this repository also includes repositories with data available on demand or commercial repositories.

Zenodo

• https://zenodo.org/

Zenodo is a general repository supported by the European Commission and operated by CERN. It is open to researchers from all fields of science. It allows sharing of articles, conference papers, presentations, but also raw research data. It allows you to search for shared scientific data and easily reuse it.
For sharing research data and software created at BUT, we have created a Zenodo community - https://zenodo.org/communities/but

Dryad

• https://datadryad.org/

The repository contains research data mainly from the life and medical sciences. The Dryad system aims to allow researchers to validate published results, explore new methods of analysis, reuse data for research questions not anticipated by the original authors, and conduct synthetic studies such as formal meta-analyses.

Harvard Dataverse

• https://dataverse.harvard.edu/

Harvard Dataverse is a cost-free data repository open to all researchers in any field, both inside and outside Harvard. Here you can share, archive, cite, access, and explore research data.

Figshare

• https://figshare.com/

It is a data repository supported by Digital Science, part of the Springer Nature portfolio. Users can make all their research outputs available here so that they can be found, reused and cited.

National repository

• https://data.narodni-repozitar.cz/

The National Repository is still in pilot operation, but in the future it will be one of the main repositories of research data in the Czech Republic. It is operated by CESNET as part of the pilot development of the national repository platform. The virtual organisation for user access and community within the repository (i.e. currently controlling the records stored) is managed by the National Technical Library.
