# Liferay Dual-Licensing

This software is available to you under a dual-licensing approach, where you may choose one of two options:

- **FOSS [GNU Lesser General Public License v2.1 or later][lgpl-2.1-or-later]**. You may use it under either LGPL-2.1 or any later version of the LGPL, such as the LGPL-3.0.
- **Proprietary [EULA: Liferay Digital Experience Platform And Certain Applications (2002306_GL)][dxp_eula]**, available through a _[Liferay Enterprise Services Agreement][esa]_, for Liferay's subscription customers. If you wish to become a subscription customer, contact Liferay at <https://www.liferay.com/contact-sales>.

If you opt to use the code under the LGPL-2.1 license (instead of LGPL-3.0), Liferay is a signatory of the [GPL Cooperation Commitment][gplcc]. This means that if you violate the LGPL-2.1, Liferay would apply the much more friendly grace period and automatic license reinstatement from the GPL-3.0. For more information, see [our public commitment][gplcc_liferay] and this [blog post][gplcc_blog].

## SPDX and REUSE Standards

The above licensing terms are expressed in [SPDX language][spdx_id] with the following unambiguous identifier in every source code file released to you under these licenses:

`SPDX-License-Identifier: (LGPL-2.1-or-later OR LicenseRef-Liferay-DXP-EULA-2.0.0-2023-06)`

The texts of both licenses is in the `LICENSES/` folder in the root of this repository/package, with the SPDX ID of each license as the base file name:

- [LICENSES/LGPL-2.1-or-later.txt](LICENSES/LGPL-2.1-or-later.txt)
- [LICENSES/LicenseRef-Liferay-DXP-EULA-2.0.0-2023-06.txt](LICENSES/LicenseRef-Liferay-DXP-EULA-2.0.0-2023-06.txt)

This adheres to the [REUSE Software 3.0 specification][reuse], a community best practice for the standardized declaration of copyright and licensing information for software projects.
