Now known as "Demystify" with thanks to Joshua Ng for the suggestion to rename it. Demystify is an engine for the analysis of DROID CSV export files, Siegfried YAML export files, and Siegfried 'DROID compatible' output. The tool has three purposes, break the exports into their components and store them within a table in a SQLite database; create additional columns to augment the output where useful; and query the SQLite database, outputting results in a readable form useful for analysis by researchers and archivists within digital preservation departments in memory institutions.

The tool provides archivist definitions for each of the sections output; these definitions are customizable. The tool also supports output of statistics about files that may require further triage or may not be appropriate for long-term preservation based on institutional rules, in the form of a blacklist. The tool also analyses file names and directory names for non-ascii characters, and also characteristics that may present problems cross-file-system based on known Microsoft rules: http://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx

The engine can be used to generate a list of file paths for files that may present digital preservation risks (Rogues) or files which on the surface i.e. via identification alone, look okay (Heroes) and these listings can be used in conjunction with rsync to isolate these sets from one-another to be more flexible to work with.
