When sharing research data, you should select an appropriate data repository.
There are various types of data repositories, including disciplinary repositories, institutional repositories, and general-purpose repositories.
If the organization from which you receive a research grant or to which you submit a thesis has a data repository policy, you need to select a data repository that complies with the policy.
If your academic discipline already has a widely accepted disciplinary repository, it will be appropriate to have it as your top choice.
If there is no such disciplinary repository, you should select from data repositories while paying consideration to the following matters in general terms:
Data Repository Selection Decision Tree for Researchers in the Earth, Space, and Environmental Sciences(Enabling FAIR DataCommunity, Ruth Duerr, Danie Kinkade, Michael Witt, & Lynn Yarmey. 2018) is a source of reference for you to select from repositories.
CoreTrustSeal is a system for certifying the reliability of each data repository. Having CoreTrustSeal certification is one of the key conditions for data repositories that deserve selection.
In addition, some publishers have released lists of recommended repositories.
Kyoto University Research Information Repository (KURENAI) is Kyoto University’s institutional repository on which all members of Kyoto University can register content. The revision of the repository operational policy in June 2019 has made it possible to register research data on which various research works are based as well. If you are interested in it, please refer to the page "Depositing Research Data in KURENAI".
KURENAI has no CoreTrustSeal certification yet. Please note that this repository may not serve your purpose if the organization from which you receive a research grant or to which you submit a thesis requires you to register your research data on a certified repository.
On general-purpose repositories, you can register a wide range of data regardless of the discipline. Major examples are as follows:
The following two websites compare various repositories.
However, please note that these websites may not give the latest information.
