YAML Introduction


YAML(Ain’t Markup Language) is a human friendly , cross language, unicode based data serialization format designed for interaction with all programming languages.

File Name Extension : .yml or .yaml

Latest Release : 1.2

It is broadly use for programming:

  • Configuration Files
  • Internet Messaging
  • Object Persistence to data auditing
  • Also support for Unicode standards characters.

YAML allow data to show itself in a natural and meaningful way and provide a unique cleanness by minimizing the amount of structural characters.
For example: indentation may be used for structure, colons use to separate “mapping key: value” pairs, and dashes are used to create “bullet” lists for showing collections of data.

YAML is a superset of JSON : you can convert YAML to JSON by different API’s

YAML Goals

Below are main design goals for YAML :

  • YAML is easily readable and understandable by humans.
  • YAML is expressive and extensible.
  • YAML is easy to implement and use.
  • YAML matches the native data structures of agile languages.
  • YAML data is portable between programming languages.
  • YAML has a consistent model to support generic tools.
  • YAML supports one-pass processing.

YAML Documents Processing

A YAML document is parsed only when the iterator is invoked (lazy evaluation).
