YAML document description
The yml file extension is related to YAML, a human-readable data serialization format that takes concepts from languages such as XML, C, Python, Perl, as well as the format for electronic mail as specified by RFC 2822. It is available for several programming and scripting languages.
YAML is an 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-centric, rather than document markup.
