YAML is a human-readable data serialization format that takes concepts from programming languages such as C, Perl, and Python, and ideas from XML and the data format of electronic mail (RFC 2822). YAML was first proposed by Clark Evans in 2001, who designed it together with Ingy döt Net and Oren Ben-Kiki. It is available for several programming languages.
YAML is a recursive acronym for “YAML Ain’t Markup Language”. Early in its development, YAML was said to mean “Yet Another Markup Language”, but was retronymed to distinguish its purpose as data-oriented, rather than document markup.
