Background

Most Harvard schools use the ProQuest ETD Administration tool to manage Electronic Thesis and Dissertation submission. After a school accepts and approves an ETD, the actual files created by the student need to be deposited into the DRS for preservation.

Packages from ProQuest

ETDs from ProQuest can have a variety of files and file types.  Each file with a currently supported DRS Content Model will need a separate DRS Object and be assigned a 'Role' in DRS. Files that have formats that are not currently supported by DRS Content Models, like CAD files, will be put in one Opaque Object.  The DRS Content Guide explains which file formats are appropriate for each supported Content Model.

Examples:

For example, a ProQuest ETD could have the following files which would be deposited in the corresponding Content Model

• Thesis in PDF format => Document
• mets.xml file => Text
• License files in PDF formats => Document
• Supplementary files, such as thesis appendices, data sets, videos, etc,. in a variety of formats => Opaque

DRS Roles and Relationships

In DRS objects and files are assigned roles to help categorize material as well as facilitate relationships between objects. The Adding Relationships section of the BatchBuilder Guide had information on DRS relationships.

DRS Projects, Batches, Objects, and Content Models in BatchBuilder

BatchBuilder is the main tool used to organize content for deposit into DRS.  

Preparing a batch

• Get the file information for all files from the mets.xml FileSec
• Filename
• Mime-type
• Use category - CONTENT or LICENSE
• AMDID - amd_primary, amd_supplemental, amd_license 
• Create Object OSNs based on ProQuest ID, school code and Role
• Create File OSNs based on ProQuest ID and Role
• Create mapping.txt file to associate files with appropriate Object OSN and File OSN
• Get DASH URN from MARCXML if present
• Get Alma MMSID by using query with ProQuestETD ID
  

Create an object for each file

• Content Model based on file Mime-type
• Role based on Use category and AMDID
• Primary PDF thesis gets ROLE=THESIS
• Other files in CONTENT group get ROLE=THESIS_SUPPLEMENT
• Files in ‘LICENSE’ group get ROLE=LICENSE
• Mets.xml file gets ROLE=DOCUMENTATION
• File with ROLE=THESIS gets MODS descriptive metadata

Add relationships and Harvard Metadata inks to THESIS Object

• Has_supplement
• Has_licence
• Has _documentation
• HOLLIS link based on MMSID
• DASH link based on DASH ID
