1. Introduction

YAML™ (rhymes with “camel”) is a human-friendly, cross language, Unicode based data serialization language designed around the common native data structures of agile programming languages. It is broadly useful for programming needs ranging from configuration files to Internet messaging to object persistence to data auditing. Together with the Unicode standard for characters, the YAML specification provides all the information necessary to understand YAML Version 1.2 and to creating programs that process YAML information.
