I find this interesting on a number of levels. Obviously as a blogger I like the idea of being able to express my wishes on how the content I create should be used on my own terms without needing to hire a lawyer to do so. As a technologist I am intrigued as these licenses are expressed in an XML dialect called RDF that is an underpinning of all semantic web related technologies. As RDF data spins out across the net in applications like this the semantic web starts to take shape. How much longer before we start to see toolkits showing up that are more than research projects? How long before enterprse class applications emerge that build off this rich set of information that is accumulating out there?
On a more general point though, it is fantastic to see organizations like the Creative Commons taking a true world view to make their work locally applicable in a diverse set of nations and gives me something to think about on how our world is continuing to interconnect people with ideas and each other across artificial boundries.
