-The UnpackRAParquet tool has been created by the Data Science department at the National Archives of Denmark in order to make it easier to use the dataset in Transkribus.
-The tool is lightweight and extracts any parquet file found in the same directory as the executable into the correct folder structure and naming convention for import in the Transkribus desktop client, given that the parquet file contains the correct data formats.
-We take no responsibility for any issues that might occur when running the binary nor do we commit to maintaining it through new versions of Windows, parquet or other packages.

-The binary has been successfully tested on a computer running Windows 11. The checksum of the tested binary is SHA256: 30A4E7F67EABD275514721C0FD1AEE99F04C6A376CBEA5F027E1E5BD95458AAF.
