mion

mion (Minimal Object Notation) is a clean and lean alternative to JSON, which is easily converted to JSON. It looks familiar to JSON with a minimalist syntax to ensure easy readability and a small footprint. As an additional feature, mion supports list schemas, which makes it delightful to declare lists without repetition.
