Low-level license metadata integration for applications.

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

• Supports verification URLs for metadata verification

Media

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

Download

• Latest Release from Sourceforge.net
• Debian and Ubuntu repositories.
• Read the tutorial.

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. See Git for information on switching to a working copy you can push using.
