When documenting compliance, consider the following:
Element 6: Oversight of Data Management and Sharing:
The Principal Investigator, [Dr. X], will provide oversight during the project to ensure DMP compliance. Compliance will be evaluated and documented [Annually] during the Research Performance Progress Report (RPPR) and submitted to the [Grant] Program Officer. At the conclusion of the project, a final evaluation will be completed summarizing the completion of the DMP objectives including links to the shared datasets.
