## DjVu Meta Tags

This table lists the standard DjVu metadata tags, but ExifTool will extract any tags that exist even if they don't appear here. The DjVu v3 documentation endorses tags borrowed from two standards: 1) BibTeX bibliography system tags (all lowercase Tag ID's in the table below), and 2) PDF DocInfo tags (capitalized Tag ID's).
