I've been working for the past week or so on a JavaScript licensing widget that has been suggested on our wiki. It's a new way to integrate CC licensing into your web application. It's really as easy as pie: Just add the following tag somewhere in the body:
and a CC licensing widget will appear. Your web application can then use
regular DOM queries to determine the user's choice.
NOTE that this is not ready for prime-time use! I want feedback on what people would like us to add or change. Right now it serves only English-language text; in the future you will be able to add ?locale=, stick your language code at the end, and get text back in your language. Beyond translation, tell me how else I can be of service!
You can download a trivial sample application and a long-ish README at our SourceForge project. For y'all's convenience here's a link to the README.
It'll take you all of five minutes to deeply understand what's going on, so I suggest you do if you're thinking about (or if you already are) offering CC licensing to users of web applications you work on.
