Frequently Asked Questions

Quick answers to common questions about DDL-v1.

General

What does DDL-v1 stand for? Datacustodia Dataset License, Version 1.

Where is the authoritative license text? In licenses/License.txt at the root of the source repository. Everything else is plain-language guidance.

Can I use a DDL-v1 dataset in my country? The license is intended to operate worldwide. Some local laws grant mandatory exceptions (e.g. fair use, quotation rights); those continue to apply (see Section 10 of the License).

Use

Can I train an AI model on a DDL-v1 dataset? Yes, for non-commercial purposes. See Section 16 of the License for the specific rules on training, fine-tuning and model outputs.

Can I use a DDL-v1 dataset at my for-profit company? Only with a separate commercial license from the Licensor. See the Commercial Licensing page.

Can I share a DDL-v1 dataset on my website or mirror? Yes. As a mirror operator you become a “Further Distributor” and must follow the attribution rules (see Section 17 of the License).

Attribution

What is the minimum attribution I need to give? The Licensor’s name, the dataset title, the DDL-v1 version label, and where practicable a source URI. Adaptations must be marked as such.

Can I include the attribution in a NOTICE file instead of a README? Yes, as long as it travels with the redistribution and is at least as prominent as the attribution for any comparable third-party material.

Compliance

What happens if I breach the license? Your Licensed Rights terminate automatically. They may be reinstated if you cure the breach within 30 days, or sooner if the Licensor grants express reinstatement.

Can I get a retroactive commercial license? Contact the Licensor. Retroactive licenses are not guaranteed, but the Licensor may, in its sole discretion, agree to one.
