# OpenDB Licensing Notice

New protected database material identified below is offered under unmodified [CC BY-NC-SA 4.0](LICENSE.txt). Commercial exercise of those rights requires separate permission from the relevant rights holder. This notice defines coverage and adds no conditions to the standard license.

## Coverage

**No new database material is currently designated as covered.** Previously published ODC-By 1.0 material retains its earlier permissions, including commercial use under that license. Republishing or editing it does not revoke those grants. The [original ODC-By text](docs/licensing/ODC-By-1.0.txt) is preserved.

The legacy baseline is commit `2ec94628fa91bcd175742da900b89d56ddcb810d`, with `open-db/` tree `cb63a9b4f797ca6a3fc0269b9ddc8db99b20c9cd` and license blob `c689af831388d77e3f8e13688e6ea499aab0995b`. Earlier grants in other releases also survive; this baseline is not an exhaustive list or a claim to be the latest release.

Before releasing new covered material, add a record identifying:

- The database portion and exact commit or release, including incorporated legacy material.
- The protected contribution, rights holder, and supplied attribution.
- Sources, third-party terms, exclusions, and authority to license the identified rights. Reference verified permission records without publishing private agreements or signatures.

The license grants only rights the licensor controls. Ordinary facts, statutory exceptions, and independent permissions remain unaffected. New identifiers or file formats do not establish new protected rights. This notice does not assign new licenses to software, schemas, logos, photographs, manuals, or other third-party content.

## Attribution and forks

For covered material, retain supplied attribution and notices, identify changes, and provide the license text or link under CC section 3(a). Suggested credit:

> Contains data from BuildCores OpenDB (https://github.com/buildcores/buildcores-open-db), licensed under CC BY-NC-SA 4.0 for identified covered material. Source release: [identifier]. Changes: [description]. Legacy material retains its earlier permissions and notices.

Publicly shared protected adaptations must use an adapter's license permitted by CC section 3(b); applicable database rights are addressed in section 4. The original noncommercial restriction remains. Private changes, independent application code, and unprotected facts do not have to be published.

See the [licensing guide](docs/licensing/README.md) for commercial requests and contributor permissions. BuildCores can approve only rights it owns or is authorized to license, including in forks.
