DocLang
DocLang is the AI-native markup format for unstructured content — including documents, images, and more. It maps cleanly to LLM tokens while preserving structure, semantics, layout, and geometry in a single, unambiguous representation.
This repository is the home of the normative specification and the reference toolkit for DocLang. If you build with LLMs and VLMs on real-world content, this is where the standard lives.
Specification
The source of the specification is available in spec.md and exports to different formats can be found in the exports/ directory.
Reference Toolkit
The commands below illustrate basic scenarios. For advanced installation and usage options (minimal install, platform notes, custom Schematron backends, Python API), see the toolkit README.
Installation
pip install "doclang[schematron-saxon]"
Validation
doclang validate -n my_document.dclg
Packaging
doclang pack my_document.dclg
