Liblicense

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
