Alias

To assign a token as a value for another token. This occurs when connecting tiers of tokens together.

Example

input.critical.bdColor = color.red.500

In the above example, the semantic token input.critical.bdColor is made as an alias of the primitive token color.red.500.

NOTE

In the DTCG specification, you can alias with a special syntax using {} characters at the $value to reference another token.

{
  "input-critical-borderColor": {
    "$type": "color",
    "$value": "{color-red-500}"
  }
}

This is helpful because we can change that assignment to serve another value without needing to visit each place using that token.
