'Scandium' is a virtual server set up and maintained by Indiana University Library Technologies (key contact: Brian Wheeler). 

Access and User Permissions

To grant access to Scandium for BDPL staff, librarians, or other authorized individuals, the BDPL manager needs to send a written request to Brian Wheeler, specifying any required permissions and identifying which network share the user needs to access.  Library staff from collecting units should not have access to the network shares of other units to avoid any issues related to user error or unauthorized access.

NOTE: if individuals who are not IU Library staff have been granted access to Scandium, the BDPL manager must track their access.  Once they no longer need to access Scandium, the manager should contact Library Technologies (Brian Wheeler) and request that their access be removed.

Directory Structure


The 'bdpl' share on Scandium contains three directories:

  • Archiver_spool: contains a single watched folder, \general%2fmediaimages\.  On a regular basis, the Archiver HPSS interface looks for content in here and then uploads any files to the Scholarly Data Archive (SDA).
  • spreadsheets: home of the BDPL master spreadsheet and workbooks for all completed shipments.  The master spreadsheet serves as a record of all contents deposited to the SDA from the BDPL, with information on each item as well as cumulative statistics for shipments as a whole.
  •  workspace: used to facilitate the transfer of files to the SDA (in cases where sources acquire content via email, network transfers, download, etc.) and provide working space for BDPL procedures.


Taking a closer look at the \workspace\ folder, we see a number of source unit folders as well as two directories ('media-images' and 'bdpl_transfer_lists') used in BDPL procedures.

  • media-images: used to store scanned photographic images of physical media, created as part of the BDPL's procedures to maintain the authenticity and integrity of content.  
  • bdpl_transfer_lists: used to store lists of files or folders that will be copied from a source location to a barcode folder in the BDPL workspace.  (Additional information about the use of transfer lists will be provided in the overview of the BDPL content transfer process.)

The other folders are named with a unique acronym or abbreviation for collecting units that transfer content to the BDPL for migration and ingest (e.g. 'MPP' is for Modern Political Papers). 


A unit folder contains three subfolders:

  • completed_shipments: storage location for a copy of the item manifest of completed shipments.  These are only copied here once everything in the shipment has been transferred to the SDA (or deleted, if unnecessary).
  • dropbox: used by the collecting unit to send shipments to the BDPL when contents are acquired via network transfer, email, download, or other means not involving physical media.
  • ingest: location used by BDPL staff to migrate and perform analysis on content.


The \ingest\ folder will include once subfolder for each shipment the unit has sent to the BDPL (please note that the unit acronym and shipment date comprise a unique shipment ID, as outlined in the shipment overview). 


A shipment folder will contain a copy of the manifest workbook as well as a single folder for each barcode item:

The structure of the barcode folders will be discussed further in the section of this documentation related to BDPL Submission Information Package (SIP) structure.
