# Odexa licensing

Approved for publication on **17 September 2026**. Copyright © 2026 Odexa contributors, to the extent copyright subsists. “Odexa contributors” identifies the respective contributors and does not assert an incorporated legal entity or transfer their ownership.

This package applies the following licences to original Odexa material:

| Material | Licence |
| --- | --- |
| Specification and explanatory documentation prose, including Markdown guides and reports | [Creative Commons Attribution 4.0 International (CC BY 4.0)](LICENSES/CC-BY-4.0.txt) |
| Schemas, vocabularies, examples, reference source code, clients, tests, fixtures and implementation/build configuration | [Apache License 2.0](LICENSES/Apache-2.0.txt) |

Implementation material embedded in documentation, such as code blocks, JSON examples and machine vocabulary definitions, is covered by Apache-2.0; the surrounding explanatory prose is covered by CC BY 4.0. This separation permits implementations and commercial reuse under the applicable licence without requiring a provider account or protocol royalty. The full licence texts control the grant and its conditions.

For documentation attribution, identify **Odexa contributors**, retain any more specific supplied attribution, link to the source document and CC BY 4.0, and indicate modifications as required by that licence. Preserve applicable notices and licence copies when redistributing implementation material under Apache-2.0.

Third-party dependencies and separately attributed third-party material retain their own licences; these grants do not relicense them. The **Odexa and Ortello names, logos and trademarks are excluded from these grants**. No endorsement, certification or trademark permission is granted; any rights otherwise available under applicable law remain unaffected.

The service/evidence release remains **`1.2.0-draft.2` — developer preview**, with the policy core at `1.2.0-draft.1`. Licensing does not establish production readiness, an external audit, legal clearance or absence of third-party patent claims. Apache-2.0 contains its own limited contributor patent grant; no additional essential-claims or patent-clearance guarantee is made here.

The complete licence texts are retained without modification in `LICENSES/`. Apache-2.0 was downloaded from Apache's official site. The CC BY 4.0 text uses the SPDX project's maintained copy because the canonical Creative Commons text download returned HTTP 403. The canonical terms remain Creative Commons' legal code. See [text provenance and SHA-256 hashes](LICENSES/README.md).

This notice supersedes earlier statements in this package that publication-licence selection or approval remained pending. Release stewardship, contribution procedures and governance remain separately documented work.
