JSON Schema can be used to validate Hjson documents. Hjson, a user interface for JSON (Hjson) adds new language features and relaxes syntax restrictions aiming to make information entry easier and less error prone. Hjson only intends to be an intermediary between humans and JSON, as such the clear schema language is JSON Schema.

JSON
