Should we also display the Creative Commons license? and if so, is the summary sufficient, or should the whole license be displayed?

My preference would be for the summary to be displayed together with a link to the full text. --annew 17:19, 9 November 2008 (UTC)

Not necessarily. In fact, AFAIK we shouldn't. The GFDL requires that you included a copy of the complete license in what you're distributing. And that's what we have here. The CC requires that you link to the appropriate Commons Deed on their site. --Jucato
