To make your research data open, you can deposit it in dedicated data repositories. Some repositories, such as Zenodo, accept both publications and datasets.

Data repositories allow you to provide persistent links to your datasets, so that they can be cited, linked and tracked. Just like other publications, you can license your data to define what level of reuse you allow.

OpenAIRE recommends to use the Creative Commons CC0 Waiver or CC BY licence for open access to data, as they allow maximum reusability and interoperability.
