At a wine and conversation-fuelled bash at The October Gallery in London’s Holborn last night, the Creative Commons licenses for England and Wales were launched. These are a set of legally-enforceable licenses for digital content that allow the originator to specify their requirements for attribution and to place limits on consequential use of their content. If you believe as I do, that the currency of knowledge is attribution, then this model of encouraging distribution and meme-building without losing that acknowledgement is both flexible and necessary.
