Metadata
For digitized audio and video materials, the State Archives of NC requires all metadata for the digitization project to be included as a CSV file, and all XML metadata to be included as sidecars with the files. See the template CSV files for an example of how these files should be formatted. All incoming digital files should be "bagged" using Library of Congress's Bagger Tool using a SHA-256 hash. The Library of Congress GitHub has more information and provides access to download the tool. The following metadata is required:
