Based on recommendations from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Office of Data Science and Sharing, the INCLUDE Data Coordinating Center (DCC) and the associated National Institutes of Health (NIH) Steering Committee proposed to implement the NIMH Data Archive Global Unique Identifier (NDA GUID) in the INCLUDE Data Hub. You can find more information on the GUIDs processes through the INCLUDE DCC Help Center Quick Start Guide under Additional Resources.
A step-by-step guide for how to generate GUIDs with the NDA GUID tool can be found here.
