MOL (Markdown Object Language) is an alternative to JSON/XML, which is both more human friendly (very natural/easy to edit), and more LLM friendly (uses less tokens, LLMs like .md format already). It's basically a formal spec for parsing markdown-based config files, data files, etc. You can check it out at GitHub under mol-format/mol-specs. Supports JS/TS/.net/Rust currently with zero-dependency packages. Easy to implement in other languages. Maybe it's useful to other devs as well. Happy to hear feedback/criticism.
