The document discusses the need for open access to information and knowledge, arguing that information generated with public funding should have free and open "passports" or licenses. It identifies three key themes: public goods, innovation systems that involve open participation from all actors, and Web 2.0 technologies that enable user-generated and openly reusable content. The document suggests that for open exchange of information to occur, both the content itself needs to be openly licensed, and the tools and systems that share the content should also be open.
