The Licenses
There are many ways to license open source software.  Here are a few of the most popular:

  • GNU -- The most popular license.  Over half of all open source software is licensed with versions of these licenses.  The GNU organization is inexorably linked to open source software.
  • Creative Commons -- The majority of learning objects created as Open Educational Resources (OER) are licensed using these models.
Here is the complete list of Open Source Initiative approved licenses.
