It notes that as of January 2011, NSF will require a data management plan for all new grant proposals as well as existing grants. The plan must address what data will be collected and how it will be organized, preserved, shared, and accessed. It emphasizes the importance of effective data management for facilitating research by both the principal investigators and other researchers. The document provides guidance on developing a data management plan that meets NSF's criteria and effectively manages research data.
