Funders and publishers will provide some guidance on what data to share in order to meet their policies. For example, publishers typically recommend that you share all the data supporting the publication, or all the data necessary to replicate the research presented in the publication.
You may be considering other reasons to share your data, such as whether the data are vulnerable or historically significant. Such data make excellent candidates for preservation and sharing.
Ask yourself these questions before sharing your research data:
Data in the categories above may not be openly shareable. Most funder and publisher policies exempt data that needs to be restricted for valid reasons, including cases like those mentioned above. You may need to provide justifcations to your funder or publisher for the data you are unable to share.
