Lesson 306 of 2116
Licensing Your Own Datasets
If you build a dataset, how you license it determines who can use it and how. Picking the right license matters as much as the data itself.

Unlicensed Data Is Unusable Data
Put a dataset on the internet with no license and most legitimate users will walk away. Without a license, they have no legal right to use it. The license is your instruction manual for what the world can do with your work.
Common dataset licenses
Compare the options
| License | Commercial | Share-alike | Attribution | Example dataset |
|---|---|---|---|---|
| CC0 / Public Domain | Yes | No | No | Some Kaggle datasets |
| CC-BY-4.0 | Yes | No | Yes | Wikipedia-derived data |
| CC-BY-SA-4.0 | Yes | Yes | Yes | OpenStreetMap |
| CC-BY-NC | No | No | Yes | Academic-only datasets |
| MIT | Yes | No | Yes | Many code datasets |
| Apache 2.0 | Yes | No | Yes | Many ML datasets |
| OpenRAIL-M | Restricted | No | Yes | BigScience BLOOM data |
Non-commercial is often a trap
Responsible AI licenses
OpenRAIL (Responsible AI Licenses) are a newer family of licenses that permit commercial use but forbid specific harmful applications (surveillance, discrimination, etc.). BigScience released BLOOM under OpenRAIL. These licenses are legally novel and still being tested in courts.
A checklist for licensing your dataset
- 1Confirm you have the right to license every piece of included data
- 2Decide whether commercial use is OK
- 3Decide whether derivatives must be shared on the same license
- 4Require attribution unless you really mean to waive that right
- 5Document use-case restrictions in plain language
- 6State how users should report violations
- 7Pick a well-known license (avoid writing your own)

The big idea: your license is a promise to the world about how your data can be used. Pick it carefully, document it prominently, and remember that well-licensed data travels further than cleverly restricted data.
