rel=jslicense is a method for linking to a URL to both the license and source code for the JavaScript programs provided by a given page or site.

Publishers

On a page that provides multiple JavaScript programs, publishers should provide a visible hyperlink to a page that provides information about those programs's license and source code.

For an example of how to provide such a page with licensing information (and some reasons why), see: JavaScript License Web Label.

Limitations

The JavaScript Web Labels recommendation also allows for inline JavaScript; such JavaScript may not appear on the Web Labels page.

Consuming Code

Consuming code should parse for rel=jslicense per normal HTML5 parsing rules, and if present, provide a UI to the user summarizing/describing those licenses, e.g. it could tell the user if the JS on the page was all open source, a free software license, etc.

Issues

None currently. rel-jslicense-issues can be created if necessary, or add brief issues inline below.

Examples in the wild

Examples of sites publishing rel=jslicense:

Implementations

Implementations of rel-jslicense, i.e. consuming code, UIs for publishing rel-jslicense etc.

LibreJS

While the links with rel=jslicense should link to human readable table of javascript license and source information, there is also a browser extension, LibreJS designed to parse these pages and to check whether or not the JavaScript is provided under a free software license.

Research

Previous Examples

Examples of other various methods sites have used to markup and/or publish licenses for their javascript (provided here inline for convenience, could be moved to jslicense-examples for research archival if necessary)

  • DefectiveByDesign.org javascript
    • inline script tag in page with demarkers @licstart @licend inside /* */ JS comments
    • Table of rows of a link to a .js file and a link to its license
  • h-node.org javascript
    • Table of rows of a link to a .js file and a link to its license
