From a PLOS Blog Post:
To support the selection of data repositories for authors, PLOS has identified a set of established repositories, which are recognized and trusted within their respective communities. To develop the list, we consulted with editors, organizations running data repositories, and other publishers in order to cover the breadth of disciplines and subject areas published by PLOS.
Additionally, the Registry of Research Data Repositories (Re3Data) is a full scale resource of registered repositories across subject areas. Researchers can browse by subject, content type, and country. Re3Data provides detailed information on an array of criteria to help researchers identify the most suitable repository for their needs (licensing, certificates & standards, policy, etc.).
