Array elements in the YAML file contain separate lines, Also called multiline array strings. Let’s declare key and value as an array in YAML. We have to use a sequence with key=roles, and value is a multi-line array of strings. Here is an example of the YAML sequence that is the same as multi-line strings.
In this regard, does YAML support arrays?
An array can contain any valid YAML value. The values in a list do not have to be the same type.
Likewise, people ask, how do you represent a list in YAML?
YAML Syntax
- There’s another small quirk to YAML. …
- All members of a list are lines beginning at the same indentation level starting with a “- ” (a dash and a space):

- Values can span multiple lines using | or > .
How do you represent an array of objects in YAML?
An array is a group of similar values with a single name. In YAML, Array represents a single key mapped to multiple values. Each value starts with a hyphen – symbol followed by space. In a single line, write the same thing above using ‘square brackets syntax.
Is YAML better than JSON?
JSON is comparatively faster than YAML. However, if data configurations are small then YAML is better since its interface is much more friendly. JSON has a feature to encode six different data types like an object, array, strings, numbers, null and boolean.
Is YAML better than XML?
The biggest difference, though, is that XML is meant to be a markup language and YAML is really more of a data format. Representing simple, hierarchical data tends to be more gracefully done in YAML, but actual marked-up text is awkward to represent.

What is schema in YAML file?
The concept of a Schema
In the context of validating a YAML file, this is referred to as a “schema”. A schema defines the general structure to which files should adhere. A specific file can then be checked against that schema to verify whether it is valid or not.

Why hyphen is used in YAML?
Dashes/hyphens only indicate the start of a list item, no matter what type that item may be. They have nothing to do with key-value pairs (i.e., dictionary items.) Both a ‘s and e ‘s values are lists, even though a ‘s list elements are dictionaries (aka maps), whereas e ‘s list elements are strings.
