Life scientists have been reported as the most ready to share research data \cite{Jones_2019} \cite{Grant_2018}. Researchers working in all disciplines where data are generated are embracing it to an extent, perhaps looking forward to the greater impact they can create \cite{data} \cite{mark}. Early career researchers may be particularly well-prepared \cite{Sholler_2019} \cite{Campbell_2019}. Even in health science disciplines, where research data is associated with complex ethical issues like consent and privacy, the obligation to share clinical trial data is recognised \cite{Taichman_2017}.   
When researchers are ready to share data publishers and journals play an important role in enabling and realising the benefits \citep{Wu_2019}. They help communicate and explain standards and expectations. They help researchers meet the data sharing requirements set by their funders \cite{easier}. They can increase the discoverability of shared data, perhaps 1000-fold \cite{Vines_2013}. They can prompt researchers to "plan for the longevity, reusability, and stability of the data" \cite{samors2018a}
