Nice! I wrote a little parser for it (https://github.com/lgastako/jevko). It was fun. I'll have to play with building higher level formats on top of it.
For a simple higher-level format, have look at Easy Jevko:
* https://github.com/jevko/easyjevko.lua – implementation in Lua
* https://github.com/jevko/easyjevko.js – implementation in JS
A way to complicate it is to add a schema like: https://github.com/jevko/interjevko.js
A lousy demo of that (with syntax coloring!) is here: https://jevko.github.io/interjevko.bundle.html
I hope to work out simple specs for these formats eventually.
