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.

Features

  • 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.

Future Improvements

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.
