  • Research Data “… recorded factual material commonly accepted in the scientific community as necessary to validate research findings, but not any of the following: preliminary analyses, drafts of scientific papers, plans for future research, peer reviews, or communications with colleagues. This "recorded" material excludes physical objects (e.g., laboratory samples).” U.S. Office of Management and Budget
  • RESEARCH LANDSCAPE  Social Science and Humanities Research Council (SSHRC): "All research data collected with the use of SSHRC funds must be preserved and made available for use by others within a reasonable period of time. SSHRC considers "a reasoable period" to be within two years of the completion of the research project for which the data was collected.“  Canadian Institutes of Health Research (CIHR): "deposit bioinformatics, atomic, and molecular coordinate data into the appropriate public database (e.g. gene sequences deposited in GenBank) immediately upon publication of research results." and "retain original data sets for a minimum of five years (or longer if other policies apply)."
