Data stewardship

From Science Europe Data Glossary

Definition: data stewardship is the management and oversight of an organization's data assets to provide professional users with high quality data that is easily accessible in a consistent manner.
Alternative definition: data stewardship is also used as a near-synonym of research data management, with the main distinction that data stewardship includes long-term archiving or preservation, whereas data management in this view is restricted to the active phases of the research data lifecycle.
