Registry of Unencumbered Software Projects


This is a collaborative metadata registry of unencumbered <https://ar.to/2010/01/dissecting-the-unlicense>__ public-domain software projects. That encompasses all projects using the Unlicense <https://unlicense.org>, Creative Commons Zero (CC0) <https://creativecommons.org/publicdomain/zero/1.0/>, or a plain old public-domain dedication.

Project metadata are described in JSON format, one file per project, utilizing the terms from the DOAP (Description of a Project) <https://github.com/ewilderj/doap>__ schema.

The current plan is that this project metadata will be made available in HTML, JSON, and JSON-LD <https://en.wikipedia.org/wiki/JSON-LD>__ format at Unlicense.org <https://unlicense.org>__ going forward.

All material in this repository is itself in the public domain.

Example Project Description

See projects/sqlite.json <https://github.com/unlicense/unencumbered-software/blob/master/projects/sqlite.json>__ for an example of how to describe a project:

.. code-block:: json

{ "name": "SQLite", "homepage": "https://sqlite.org", "shortdesc": { "en": "The most used database engine in the world." }, "repository": { "browse": "https://sqlite.org/src", "location": "http://sqlite.org/cgi/src" }, "license": "https://sqlite.org/copyright.html" }

Frequently Asked Questions

Q: How can I suggest a project without submitting a pull request?

A: To just suggest a project addition, please tweet at @TheUnlicense <https://twitter.com/theunlicense>__ on Twitter.

Q: Will you accept WTFPL or 0BSD projects?

A: No, as these are not public-domain dedications but rather maximally-permissive copyright licenses. Please see Licensed, License-Free, and Unlicensed Code <https://ar.to/2010/12/licensing-and-unlicensing>__.

Q: Will you accept non-software projects in the public domain?

A: No, not in this registry. Consider submitting non-software projects to johnjago/awesome-uncopyright <https://github.com/johnjago/awesome-uncopyright>__ instead.
