For monograph and manuscript materials, we group files into items and items into a batch³.  For example, the following batch contains three items.  Two items contain only JPEG2000 image files, and one item contains JPEG2000, OCR plain text, and OCR ALTO XML files.

    [BATCH ID] (example: Batch02 or Box03)
        |-- [UNIQUE_ID]-mets.xml (single volume METS file example: 007984492-mets.xml)
        |-- [UNIQUE_ID]_[VOLUME_ID]-mets.xml (multivolume METS file example: 000652831_v0002-mets.xml)
        |-- [UNIQUE_ID]-mets.xml (manuscript collection METS file example: morgan_601_705_volIV-mets.xml)
        |-- [HOLLIS_ID].xml (MARCXML or MODS xml file, e.g., 000652831.xml)
        |
        |-- [UNIQUE_ID]/ (manuscript collection example, e.g. morgan_601_705_volIV)

Here is another example from Black Teacher Archive Project showing a batch with project specific file name patterns.

Organization of files with "Bagit" packaging

    <root directory>
      |-- bag-info.txt  
      |-- bagit.txt
      |-- manifest-md5.txt
      |-- tagmanifest-md5.txt
      |
      |-- data
           |-- [ THE SAME DIRECTORY STRUCTURE AS THE SIMPLE PACKAGING ABOVE ]

Delivery media and transfer method

...

• Hard disk, flash drive
  • The repositories can borrow the media from Imaging Services or pay for them
  • Recommended for large sets of data
• Google shared drive
  • A google account from the data recipient needs to be provided to Imaging Services
• MS shared directory
  • The data recipient's email address needs to be provided to Imaging Services
  • Suitable for small sets of data
• Secure file transfer (https://filetransfer.harvard.edu)
  • The data recipient's email address needs to be provided to Imaging Services.
  • The data recipient outside Harvard University needs to set up a guest account.
  • Suitable for small sets of data which need encryption during file transfer.

   In cases where the record identifier includes space, the spaces will be replaced by underscores.

2. Anchor
   note2 note2

   MARCXML and MODS XML record files are only available for items that have been cataloged in Harvard’s bibliographic database, HOLLIS.

3. Anchor
   note3 note3

   Batch level identifiers are assigned to groups of titles prepared and submitted together for scanning. These named “batches” will be maintained from scanning all the way through deposit to Harvard's Digital Repository Service and transfer of data to project partners beyond the Harvard libraries. Inclusion of technical metadata is optional.
