In this webinar for ASERL members, Sayeed Choudhury, Associate Dean for Research Data Management and Hodson Director of the Digital Research and Curation Center at the Sheridan Libraries of Johns Hopkins University reviews how the executive memoranda last year from the White House Office of Science and Technology Policy (OSTP) has highlighted one of the major issues related to data sharing: Data preservation, which remains a largely-unaddressed need in the data realm. This webinar features lessons Sayeed and his colleagues have learned from the Data Conservancy as it relates specifically to the preservation needs of both "big data" and "small data." The webinar identifies both commonalities and differences between 'big' and 'small,' and outlines possible approaches to bolster our community's ability to meet the challenge of data preservation.
