Frequently Asked Questions

Explore answers to common questions about TAO’s open source license.

TAO Community Edition is an open source assessment platform. Its core functionalities and components are released under the AGPLv3 license.

AGPLv3 stands for Affero General Public License version 3. It’s a copyleft license that ensures the software and its modified versions remain open-source and accessible. A key aspect of AGPLv3 is that it requires the source code to be made available even if the software is used as a service over a network.

TAO Community Edition (CE) is licensed under AGPLv3 to promote and protect its open-source nature. It ensures that any improvements or modifications made to TAO CE are shared with the community, fostering collaboration and innovation.

The key obligations include:

  1. Providing access to the source code to users who interact with the software over a network.
  2. Including proper copyright notices and license texts.
  3. Making modified versions available under the same AGPLv3 license.

Yes, you can use TAO CE in a commercial project. However, if you modify TAO CE or use it as part of a service, you must comply with the terms of AGPLv3, which includes making your source code available.

If you do not wish to share your modifications, you might need to consider alternative licensing options, which would involve a separate agreement with the TAO CE copyright holders. Using the software under AGPLv3 requires sharing your modifications.

The full text of the AGPLv3 license is available on the GNU website. It is essential to read and understand the license before using or distributing TAO CE.

While the core of TAO CE is licensed under AGPLv3, some components or libraries used within TAO CE might have different licenses. These are typically permissive open-source licenses. Please check the documentation for specific components.

For further information or specific inquiries about TAO CE’s licensing, you can contact the TAO CE community or legal experts. Always seek professional legal advice for your specific situation.
