RSL License Servers

RSL license files can be paired with RSL License Servers that implement the RSL Open Licensing Protocol (OLP). OLP replaces replaces proprietary licensing solutions with an open standard that provide publishers and client applications with content management, licensing, and protection capabilities, including:

• License management: Enable client to license and pay for digital content assets, including billing and reporting for AI training and search applications.

• License verification: Validate a client's purchase of a free or paid license to authenticate web crawlers.

• Content protection: Manage cryptographic keys to enable publishers and clients to easily encrypt and decrypt files to implement secure sharing of proprietary digital assets.

Example Code

Below is an example RSL license that is managed by the license server https://rslcollective.org/api. The license specifies that any clients that wants to index the website must first obtain a free license from the specified license server.

<rsl xmlns="https://rslstandard.org/rsl">
  <content url="/" server="https://rslcollective.org/api">
    <license>
      <permits type="usage">search</permits>
    </license>
  </content>
</rsl>

Note

If the <content> element points to a file that ends with an .aes extension, the content is encrypted and the client must obtain a license key from the server to descrypt the file. (See also Encrypting Content)
