What is liblicense?

liblicense provides a straight-forward way for developers to build license-aware applications. liblicense utilizes a pluggable module system for reading and writing metadata from specific file types, allowing extensibility for specific content types.


  • Extract and write license information for files
  • Supports enumeration of available licenses
  • Wraps internationalized license information for Creative Commons licenses
  • Bindings for dynamic languages (currently Python and Ruby)
  • Extensible support for file types using module system
  • No specific GUI library dependency allows applications to build the graphical chooser most appropriate for their platform.

See Operating System Mockups for ideas on how liblicense could be integrated into various platforms.


Developers: Using git

If you want to check out the source code and develop on it, use this command:

git clone git://code.creativecommons.org/liblicense.git
git submodule init
git submodule update

That should give you a working copy you can commit to. In case you wonder: the latter two commandsfill the directories

  • icons/jurisdictions
  • license.rdf
  • licenses

with content from external repositories similar to svn:externals for Subversion.
