File Information Tool Set
FITS, the File Information Tool Set, is software created at the Harvard University Library to identify, validate, and extract technical metadata for various file formats. It wraps several third-party open source tools, normalizes and consolidates their output, and reports any errors. The tools which it incorporates include JHOVE, Exiftool, National Library of New Zealand Metadata Extractor, DROID, FFIdent, and Windows File Utility.
NOTE: This article should be titled "FITS" to follow the conventions of the wiki, but there is already an article on a data format by that name. Disambiguation, someone?
