Rights on the Desktop with liblicense

liblicense is a small, lightweight library that allows application developers to easily integrate support for the Creative Commons Rights Expression Language (ccREL) into their applications. liblicense can be used to read licensing metadata from files, as well as embed it in supported file types. File-type support can be added using small plugin modules. liblicense is C-based, with bindings available for Ruby and Python.

This talk will provide a brief overview of ccREL and focus on liblicense and how it can be used to “license-enable” desktop applications. We’ll show demos (with code) of how we’re developing plugins for Rhythmbox and Eye of Gnome to support embedded license metadata. We’ll also show a demonstration of how liblicense can easily be integrated into a Python-based web application.
