Exporting Extents from a Hard Drive

 

When Processing Archivists have completed processing a collection at the their workstations and have returned a hard drive with completed finding aid components to Digital Archives, Digital Archives staff prepare extents for import to ArchivesSpace using the report_hdd_extents script. This page describes instructions for preparing and exporting extents JSON files from a hard drive. See the report_hdd_extents section of our Software documentation page for installation instructions.

Review Finding Aid Components

• Attach the hard drive containing finding aid components
• Check that the FAC directory uses the naming convention CollectionID_FAcomponents
  • M18867_FAcomponents, for example
• Review the finding aid components returned by Processing Archivist(s) for system files or other formats not retained by Digital Archives.

Run report_hdd_extents.py

These instruction assume you are using FRED 2.
On computers with Google Drive you can store JSON files using the shared drive location
Digital Preservation/Stream - Digital Archives/Digital Archives Program/ASpace JSON

Prepare a destination directory

• Navigate to the FTKsettings directory in the Storage (F:) drive on FRED 2.
• Open the ASpace directory
• Create a report destination directory using the naming convention CollectionIDreport.
  • For example, the Morris Dickstein Collection directory would be M18867report

Extract extents using report_hdd_extents.py

• Open WSL on FRED 2
• Note the location of the FAcompnents directory.
  • This location will be used after the -d flag in the command.
• Note the location of the destination directory previously created.
  • This location will be used after the -o flag in the command.
• Run report_hdd_extents.py script using the following command:
  python3 path/to/report_hdd_extents.py -d /path/to/CollectionID_FAcomponents -o /path/to/CollectionIDreport
• For example:
  python3 digarch_scripts/report/report_hdd_extents.py -d /Volumes/DigArch11/M18867_FAcomponents -o /M18867report

Deliver extents JSON to Archival Processing Unit

Digital archives staff should deliver the extents JSON file to the Processing Archvist(s) for the associated collection.
