What is "yaml"

n. (context computing English) A retronym for '''YAML Ain't Markup Language''' that meant originally '''Yet Another Markup Language'''

YAML (, rhymes with camel) is a human-readable data serialization language 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. Originally YAML was said to mean Yet Another Markup Language, referencing its purpose as a markup language with the yet another construct, but it was then repurposed as YAML Ain't Markup Language, a recursive acronym, to distinguish its purpose as data-oriented, rather than document markup.

YAML is available for several programming languages.

YAML (Yet Another Multicolumn Layout) is a cross-browser CSS framework. It allows web designers to create a low-barrier website with comparatively little effort. Integrations of the YAML layouts have been created for various content management systems. These include WordPress, LifeType, TYPO3, Joomla, xt: Commerce and Drupal.

As of YAML version 2.2, the framework is distributed under the Creative Commons Attribution 2.0 License (CC-BY 2.0). As an alternative for commercial use of the framework, there are two paid subscription models.
