Glossary - Y

Used as a new configuration format in Drupal 8, YAML (YAML is not Markup Language) is a simple text data format. It is defined as "a data serialization standard for all programming languages, easy to use for humans". Data serialization involves transforming a data structure, whether simple or complex, into a text file. Thus with the YAML format, it is possible to represent information such as tables, lists of tables, strings, objects and many other variables, with a better readability than the XML format.
