Strongly Typed Markup Language
github.com
A markup language that appoximates XML, but differs fundamentally in that strong data types are present. This was designed to be a quick way to serialise program data (types) into a string format. It is NOT designed as a replacement or superceder of XML. It is rather designed to be able to quickly, and expediently transform types into human-readable and program-readable form. Licensed under the MIT license.
See the README for a TL;DR-compatibly concise summary.
