"In a game like LittleBigPlanet, sharing user generated content is a big part of the experience. Ever more so, protecting one's personal creations is going to be an even bigger issue. With players expected to swap content daily, one has to wonder how will players control the distribution of unique content in the do-it-yourself platformer?The answer is that the game will utilize a simple system called \"copyright\" which is not the same as the legal sense. Players can \"copyright\" objects which are collectibles in their levels; copyright items can be used by the people who've collected them, but they won't be able to alter your content or give it away to others. Non-copyright items can be edited and shared freely by anyone. Additionally, you can control who is allowed to use your levels by  setting a difficulty rating and/or giving away invite keys.[Via Joystiq]"^^<http://www.w3.org/2001/XMLSchema#string>
