YAML stands for either YAML Ain't Markup Language or Yet Another Markup Language (wikipedia on name). It is similar to JSON, TOML, XML, and other markup languages.

Examples

Maps

Map / dictionary / hash data-types are represented via indentation. The following are equivalent.

{
  "a": {
    "b": {
      "c": "xyz"
    }
  }
}

a:
  b:
    c: xyz

Lists

List / array / sequence data-types are represented via dash-indented elements. The following are equivalent.

{
  "a": [1, 2, 3]
}

a:
  - 1
  - 2
  - 3

It can also be represented in a single line.

a: [1, 2, 3]

(For Obsidian users, note that Obsidian does not support spaces in tags even thought it is allowed within the yaml specification.)
