This Working Group addresses several community use cases: Mapping of data elements to corresponding CDEs as part of Neuroimaging Data Model (NIDM) tool development with the INCF WG on Reproducibility and Best Practices in Human Brain Imaging; Aligning CDEs between projects such as the Longitudinal Online Research and Imaging System (LORIS) and Ontario Brain Institute’s Brain-CODE; Modeling of computational measures as CDEs, e.g., volumetric measures of brain structures provided by FreeSurfer. The group is working on a specification document for common data elements.
