Stewardship (also data stewardship) is
the long-term preservation of data so as to ensure their continued value, sometimes for unanticipated uses. Stewardship goes beyond simply making data accessible. It implies preserving data and metadata so that they can be used by researchers in the same field and in fields other than that of the data's creators. It implies the active curation and preservation of data over extended periods, which generally requires moving data from one storage platform to another. The term “stewardship” embodies a conception of research in which data are both an end product of research and a vital component of the research infrastructure.
