# Contributing OAA is currently a 0.1 Draft format. Changes should be proposed and reviewed against interoperability, reader safety, and backward compatibility. ## Contribution Licensing By contributing to this repository, you agree that your contribution is licensed under the same license that applies to the file or directory you are modifying. For example: - Contributions to `SPEC.md`, `README.md`, or `docs/` are licensed under CC BY 4.0. - Contributions to `examples/` are dedicated under CC0 1.0. - Contributions to machine-readable schema files are licensed under CC0 1.0, or alternatively MIT when incorporated into software. - Contributions to scripts or other software, if added, are licensed under MIT. Do not contribute material unless you have the right to license it under the applicable license. ## Format Changes Format changes should be proposed using [proposals/0000-template.md](proposals/0000-template.md). Changes that affect valid archives or reader behavior should update these files together: - [SPEC.md](SPEC.md) - [docs/](docs/) - [schema/](schema/) - [examples/](examples/) - [requirements/](requirements/) Validator behavior changes should be coordinated with the [OAA validator repository](https://github.com/Original-Art-Archive/oaa-validator). ## Review Criteria Reviewers should evaluate: - Whether the change preserves safe archive reading and extraction. - Whether the change is portable across Windows, macOS, Linux, and web services. - Whether unknown fields and extension block data can still be preserved by round-trip implementations. - Whether examples and requirements traceability remain aligned with the spec. - Whether private collector metadata remains private by default. ## Draft Compatibility Versions before 1.0 may change incompatibly, but draft changes should still document their compatibility impact.
