Overview

Inside the single zip file, opaque container objects can contain two types of files – content files (those files being deposited for preservation), and DRS documentation files (files documenting the contents of the opaque container). See Content files and DRS Documentation Files for more information.

When preparing files for batch processing, the files should be arranged under one of two directories: either content or documentation – before the zip file is created. The DRS documentation files should be placed in the documentation directory, all other files should be placed in the content directory. The content directory is required and has to contain at least one file. The documentation directory is optional.

Example 1: Contents of an opaque object storing a presentation

content\the_presentation.ppt  
content\the_presentation_audio.mp3  
content\the_presentation_video.mpeg  
content\the_presentation_handout.pdf   
content\the_presentation_notes.doc  
documentation\drs_documentation.txt
