# How to apply a license
|
|
|
|
Originally Nextcloud was licensed under the GNU AGPLv3 only. From
|
|
June, 16 2016 on we switched to "GNU AGPLv3 or any later version" for
|
|
better long-term maintainability and to make it more secure from a
|
|
legal point of view.
|
|
|
|
Additionally Nextcloud doesn't require a CLA (Contributor License
|
|
Agreement). The copyright belongs to all the individual
|
|
contributors.
|
|
|
|
## Apply a license to a new file
|
|
|
|
If you create a new file please use a SPDX license header.
|
|
The year should then be the creation time and the email address is optional.
|
|
|
|
#### Frontend source (`.js`, `.ts`, `.css` and etc)
|
|
|
|
```js
|
|
/**
|
|
* SPDX-FileCopyrightText: [year] [your name] [<your email address>]
|
|
* SPDX-License-Identifier: AGPL-3.0-or-later
|
|
*/
|
|
````
|
|
|
|
or `.vue` files
|
|
|
|
```html
|
|
<!--
|
|
- SPDX-FileCopyrightText: [year] [your name] [<your email address>]
|
|
- SPDX-License-Identifier: AGPL-3.0-or-later
|
|
-->
|
|
```
|
|
|
|
#### Backend source (`.php`)
|
|
|
|
```php
|
|
/**
|
|
* SPDX-FileCopyrightText: [year] [your name] [<your email address>]
|
|
* SPDX-License-Identifier: AGPL-3.0-or-later
|
|
*/
|
|
```
|
|
|
|
## Apply a licence to an existing file
|
|
|
|
If you modify an existing file, please keep the existing license header as
|
|
it is and just add your copyright notice.
|
|
In order to do so there are two options:
|
|
|
|
* If a generic header is already present, please just add yourself to the AUTHORS.md file
|
|
* If no generic header is present, you can add yourself with a copyright line as described below
|
|
|
|
````diff
|
|
/**
|
|
* SPDX-FileCopyrightText: 2022 Alice <alice@nextcloud.local>
|
|
* SPDX-FileCopyrightText: 2023 Bob <bob@nextcloud.local>
|
|
+* SPDX-FileCopyrightText: [year] [your name] [<your email address>]
|
|
* SPDX-License-Identifier: AGPL-3.0-or-later
|
|
*/
|
|
````
|
|
|
|
An example of a generic license header where adding yourself to the AUTHORS.md
|
|
file is prefered please see the example below
|
|
|
|
```
|
|
/**
|
|
* SPDX-FileCopyrightText: 2024 Nextcloud GmbH and Nextcloud contributors
|
|
* SPDX-License-Identifier: AGPL-3.0-or-later
|
|
*/
|
|
|
|
```
|
|
|
|
