The Collection and Born-Digital Series objects themselves are created first, ahead of FTK processing. All FTK processed materials for a collection are processed together and are members of the Born-Digial Series set. Media objects must be linked to the appropriate series via an isMemberOf relationship.
Media (e.g. Disk Image) objects
The FTK processing must first create a set of media objects representing the physical media (hard drive, diskette, etc) on which the files were found. This has been described as a view of the "unprocessed" collection, meaning it has not been processed down to the individual units of content, the separate files.
