YAML is a recursive acronym for "YAML Ain't Markup Language". It is a human-friendly data serialization standard for all programming languages. YAML is a superset of JSON, and offers a lighter-weight, indentation-based syntax, similar to writing an outline in a text editor. YAML delimits structures with indentation, dashes to indicate sequence items, or lack thereof to indicate a mapping entry. The syntax is minimal and it is important to keep track indentation. In contrast to JSON and XML, YAML is more suitable for hand-written data using simple text editors.
