# Specification license — CC-BY-4.0

The GEML **specification documents** are licensed under the Creative Commons
Attribution 4.0 International License (`CC-BY-4.0`), so anyone may read, share,
adapt, and **build a conformant implementation** of GEML, for any purpose,
including commercially — with attribution.

This deliberately differs from the MIT license on the code (see
[`LICENSE`](LICENSE)): a specification is not software. Separating the two makes
explicit that GEML is defined by its spec, not by any single implementation, and
that an independent implementation is welcome and unencumbered.

## Documents covered

- `GEML-spec.md`, `GEML-spec_CN.md`
- `GEML-history-spec.md`, `GEML-history-spec_CN.md`
- `GEML-spec.geml`, `GEML-history-spec.geml`, `GEML-history-spec_CN.geml`
  (the specs, written in GEML — and their `.gemlhistory` sidecars)
- `docs/COMPARISON.md`, `docs/COMPARISON_CN.md`, `docs/COMPARISON.geml`,
  `docs/COMPARISON_CN.geml`
