Summary

OpenDataLoader PDF v2.0 transitions from MPL-2.0 to Apache-2.0.

Apache-2.0 is a permissive, OSI-approved open-source license. It allows use, modification, and distribution — including in proprietary and commercial products — with minimal obligations. You must retain the original copyright notice and the NOTICE file, but you are not required to disclose your modifications or release your source code.

The core engine remains fully open source. Commercial Add-ons powered by Hancom AI are offered separately as optional enhancements.

License FAQ

Why did the license change?

MPL-2.0 requires file-level source disclosure for any modified files, which introduces additional legal review steps in enterprise environments. Apache-2.0 removes this obligation entirely, lowering the barrier for organizations to integrate OpenDataLoader PDF into internal tooling, data pipelines, and commercial products.

What happens to versions prior to v2.0?

All versions prior to OpenDataLoader PDF v2.0 remain under MPL-2.0 and are unaffected by this change. The Apache-2.0 license applies only from v2.0 onward.

Does this affect how I currently use OpenDataLoader PDF v2.0?

No. Apache-2.0 is more permissive than MPL-2.0. If your usage was already compliant under MPL-2.0, no additional action is required.

Can I use OpenDataLoader PDF in a proprietary product?

Yes. Apache-2.0 permits use in proprietary and commercial products without requiring you to disclose your source code or modifications. You are required to:

• Retain the LICENSE file
• Retain the NOTICE file
• Include any applicable copyright notices

Can I still contribute to the project?

Yes. Contributions are welcome under the same Apache-2.0 license. The Contributor License Agreement (CLA) has been updated to reflect this change.

Is OpenDataLoader PDF still open source?

Yes. Apache-2.0 is an OSI-approved open-source license. It is the license of choice for major open-source infrastructure projects including Kubernetes, TensorFlow, and Android.

Will commercial-only features be introduced?

The core engine remains fully open source under Apache-2.0. Optional Commercial Add-ons powered by Hancom AI are available separately and are not required to use the core functionality.

Where can I verify the license of a specific version?

Each release is tagged in the GitHub repository. The LICENSE file at the root of each tag reflects the license applicable to that release.
