I'm currently working on an initiative to help increase news media transparency using the "semantic web", initially focussing on encouraging the use of microformats for news ( http://www.mediastandardstrust.org/projects/transparency.aspx - it's getting its own dedicated site in the next day or two ). One of the most important building blocks for this is being able to specify a statement of principles/ethics or code of conduct for a piece of content. I envisage this working something like rel-license. On looking around for prior work in this area, I've noticed this : http://patthorntonfiles.com/blog/2008/10/07/the-online-ethics-seal-together-we-can-be-more-transparent/ (which doesn't talk about the technical implementation of the idea, but more about providing example ethics codes, like creative commons), but not much else. Is anyone aware of other things I should look at before building some examples on the wiki ? Regards, Mark
