Data Dictionary Updates🔗

Updates not yet incorporated into JSON metadata files

The following updates have only been applied to the data dictionary information available via query tools within the NBDC Data Access Platform and DEAP. For users who download tabulated data in their original BIDS folder structure (e.g. via the "All Study Data" option), note that the metadata within these JSON files do not yet contain these updates. This is planned for a future release.
