“Use the DOE Data Explorer (DDE) to find scientific research data – such as computer simulations, numeric data files, figures and plots, interactive maps, multimedia, and scientific images – generated in the course of DOE-sponsored research in various science disciplines. The DOE Data Explorer provides access both to collections and to individual datasets that have been submitted to OSTI by their creator, by a DOE National Laboratory, or by a DOE Data Center. OSTI became a member of and a registering agency for DataCite in 2011 and now assigns Digital Object Identifiers to individual datasets. DataCite provides a good definition of a DOI and why one is important at http://datacite.org/whatisdoi. The assigning and registration of a DOI for every dataset submitted is a free service provided by OSTI to enhance DOE’s management of this important resource.”
