Open source
TEAF Light is open source
The TEAF framework is a method published across a book collection. Its reference implementation, TEAF Light, is a code and template repository, published under the MIT license.
What's open source, and what isn't
A deliberately clear distinction, so the book collection is never mistaken for something free of rights:
- The TEAF framework — the metamodel, the Loop, the governance roles — is a method published across a 4-book collection. The books are commercial publications protected by copyright, sold on Amazon.
- TEAF Light — the code, templates and technical documentation in the
teaf-lightrepository — is published under the MIT license: free reuse and adaptation, with attribution.
Copyright exists even for an open-source work: the MIT license permits reuse, it doesn't erase the project's authorship.

Contributing
How to get involved
There's no formal contribution guide or versioned roadmap yet — the repository currently follows Book IV's reference scenario (intelligent invoice processing) as its development throughline. The most direct way to contribute today: open an issue or merge request on GitLab, or share field feedback via the contact form — reason "Field feedback / contribution to V2".
