Request New License or Exception

To Request a License or Exception Be Added to The SPDX License List

The SPDX License List is a list of commonly found licenses and exceptions used in free and open source and other collaborative software. The purpose of the SPDX License List is to enable easy and efficient identification of such licenses and exceptions in an SPDX document  or elsewhere. The SPDX License List includes a standardized short identifier, full name for each license, vetted license text, other basic information, and a canonical permanent URL for each license and exception. 

The SPDX Legal Team greatly appreciates proposals for new open source licenses or exceptions to be added to the SPDX License List.  To request that a license or exception be added to the SPDX License List, please:

1)  Review the license list overview and inclusion principles.

2)  Check the license and exceptions tracking page to ensure this license or exception has not been previously requested. You can also check the status of your request on the link provided there.

3) If you are not on the SPDX-legal mailing list, please join here. If you send your license request without joining the mailing list, this will greatly slow down correspondance in both directions.

4)  Submit the following information via email to with "New License/Exception Request: <license/exception name>" in the subject line. 

Submission Requirements:

  1. Provide a proposed Full Name for the license or exception.

  6. Provide a short explanation regarding the need for this license or exception to be included on the SPDX License List, including identifying at least one program that uses this license.

Review Process:

  1. The SPDX Legal Team normally meets every 2 weeks. Part of the agenda for these meetings is reviewing any submissions for new licenses or exceptions to be added to the SPDX License List.
  2. New submissions meeting the inclusion standards and the requirements above are approved at the next available Legal Team meeting. If further information or clarification is required, the Team will reach out to the requestor accordingly.
  3. Upon approval, the new license or exception will be prepared and added to the next released version of the SPDX License List.
