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:
| File type | Content Model |
|---|---|
| Document | |
| text/xml | Text |
| JP2, JPEG | Still Image |
| mp3 | Audio |
| MS Word Document | Document |
| CAD, PowerPoint file | Opaque |
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
