More on open content! Seth Shulman who is the author of Owning the Future from 1999 has written a short article Intellectual-Property Ecology in the March 2002 edition of MIT Technology Review. In his article Shulman calls the movement to protect the conceptual or information commons as an environmental movement for the new millennium – guarding collectively against the encroachment of proprietary intellectual-property rights. The environmental theme is powerful indeed. A growing body of thinkers now believes society should view the sphere of information and ideas we call the “public domain” as an ecosystem. As such, it can remain healthy only if its relationship with the market – as embodied in intellectual-property law, technology and social practice – is kept in balance. More information on this theme is to be found at the web-site of the Conference on the Public Domain that took place at Duke Law School, November 9—11, 2001.
