The File Information Tool Set (FITS) identifies, validates, and extracts technical metadata for various file formats. It wraps several third-party open source tools, normalizes and consolidates their output, and reports any errors.
The current tools used are:
* Jhove (LGPL version 2.1 or any later version)
* Exiftool (GPL version 1 or any later version; or the artistic license)
* National Library of New Zealand Metadata Extractor (Apache Public License version 2)
* DROID (BSD version 3.0)
* FFIdent (LGPL)
o Note that the live site for ffident (http://schmidt.devlib.org/ffident/index.html) seems to have disappeared - we are now linking to Internet Archive's version of the ffident website.
* File Utility (windows) (revised BSD)
