Standard Architecture for Universal Comment Extensions or
SAUCE, as it is most commonly known, is an open
metadata protocol for tagging and describing
ASCII text files and other files, most of which generally center on or date back to the era of
BBSing. SAUCE is very similar in nature to the
MP3 ID3 tag format created in 1996 in that it carries metadata such as the title, author (artist), organization (group), as well as specific hierarchical datatype information depending on what type of file it is describing.
