# Using a DDL-v1 Dataset

## Typical scenarios

- **Academic paper using a DDL-v1 dataset.** Cite the dataset title,
  `Datacustodia Dataset License Version 1 (DDL-v1)`, and a link to the
  source. Add an "Adapted from" notice if you modified the data.
  Compliant.
- **Open-source project bundling a DDL-v1 dataset.** Ship the dataset
  with the verbatim license text and a `NOTICE`/`LICENSE` file pointing
  to the source repository. Compliant.
- **Company training a commercial model on a DDL-v1 dataset.** Not
  covered by the open grant — contact the Licensor for a commercial
  license *before* any use. Non-compliant otherwise.

## Attribution format

Where practicable, include:

1. the Licensor's name,
2. the title of the Licensed Material,
3. the version label `DDL-v1`,
4. a URI to the source, and
5. a clear "Adapted from" marker if you changed anything.

Example:

> *Dataset title* by *Licensor*, licensed under the Datacustodia
> Dataset License Version 1 (DDL-v1). Source: *URI*. Adapted from the
> original.

## Compliance checklist

Before publicly releasing anything that includes DDL-v1 material:

- [ ] Attribution names the Licensor, the dataset title and `DDL-v1`.
- [ ] A source URI is given where reasonably practicable.
- [ ] Adapted Material is clearly marked as modified.
- [ ] The use is Non-Commercial (or a separate commercial license is
      in place).
- [ ] The verbatim text of `licenses/License.txt` ships with the
      redistribution.
