A data staging repository and services to support collaboration and data sharing among researchers during the research process, and to promote publishing or archiving data and high-quality metadata in both discipline‐specific data centers and Cornell's own institutional repository, eCommons.  Cornell Library's data librarians are fielding inquiries from Cornell researchers and contributing required data management plans and/or sharing plans using the DataStar platform for grant proposals to agencies including the National Science Foundation (NSF) and the U.S. Environmental Protection Agency. With the NSF's new requirement for data management plans for all submitted proposals, we expect that the demand for these services will increase dramatically.  DataStaR was developed by the Cornell University Library with funding from the National Science Foundation.
