This document provides guidance on creating a Data Management Plan (DMP). It discusses the key elements that should be included in a DMP, such as the types of data that will be collected, metadata standards, data sharing and access policies, plans for reusing and redistributing data, and archiving data for long-term preservation. It also notes that costs for implementing the DMP may be included in the proposal budget and that the DMP will be reviewed as part of the NSF proposal process. Template codes for elements like variable names and labels that could be included in a DMP are also provided.
