Supported permissive 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 permissive software license imposes minimal restrictions on how the software can be used, modified, and redistributed. Unlike copyleft licenses, which require derivative works to be licensed under the same terms, permissive licenses allow the software to be incorporated into both open-source and proprietary projects without the obligation to release the source code of derivative works. These licenses typically require only minimal conditions, such as providing attribution to the original authors and including the original license text in any redistributed versions. The primary goal of permissive licenses is to maximize the software's usability and adoption by granting developers the freedom to integrate it into a wide range of applications, thereby fostering innovation and collaboration. In practice, there are many permissive-like license variations, such as the MIT License, the Apache License, and the BSD License. The React JavaScript library and the Apache HTTP Server are common examples of permissive-licensed software.
