ccLookup is a GUI tool built on wxPython which allows you to drop a CC licensed MP3 on the app and lookup the verification RDF. There are currently a few cosmetic problems to be worked out, along with packaging issues. Currently we have a Mac OS X disk image and Windows .zip file available from SourceForge. Before we hit 1.0 we’re planning to create a Windows installer, as well as a Linux build.
Go on, try it; let me know if you run into trouble, or if you have any suggestions.
