Supported copyleft licenses

The tables cover the following information about software licenses:

  • License name - the software license name as detected by Spectra Assure and displayed in analysis reports. Corresponds to the standardized SPDX short-form identifier.
  • License contents - link to the official SPDX website with the full text of the software license. Special, customized licenses that contain LicenseRef-rlsecure in the name do not have entries on the SPDX website. You can view a generic description for such licenses on each license family page.
  • License family - the license family that the individual software license belongs to based on its characteristics. Corresponds to one of the predefined license families.
  • Policies triggered - indicates the default policy configuration setting for the license. Some licenses are configured to always trigger a policy and raise an issue in the SAFE report. All licenses in the Weak Copyleft family always trigger the SQ12103 policy for dependencies. All licenses in the Copyleft family always trigger the SQ12101 policy for software components. If this field is empty, that means no policies are triggered by default for the license. However, users can customize the policy configuration at any time to override the default settings.

Generic license description​

A copyleft software license allows users to freely use, modify, and distribute the software, but with a crucial condition - any derivative works or redistributed versions must also be licensed under the same copyleft terms. This ensures that the freedoms to use, modify, and share the software are preserved in all subsequent versions and derivatives. By enforcing these terms, copyleft licenses aim to promote and protect the principles of free software, ensuring that the software and any improvements made to it remain accessible to the community and cannot be converted into proprietary software. In practice, there are many copyleft-like license variations, but the most well-known example of a copyleft license is the GNU General Public License GPL.
