Research data is at the heart of all scientific research. In recognition of the growing importance of robustly linking publications to their data, our parent company Springer Nature has launched a set of standardized research data policies. All BioMed Central journals have adopted one of the policies – helping lead the way in ensuring data sharing and accessibility. Services to support implementation of the policies, providing guidance to authors and editors have also been developed. We aim to have the most comprehensive and inclusive research data policy of any large publisher.
