The Momentum of Open Standards - a Pragmatic Approach to Software Interoperability
iTWire is carrying an article on an approach to Open Standards in Europe that it classes as a "must read". The article itself is available here and is being published by the European Journal of ePractice.
It's worth it for the background read and there are lots of links to various bits of research... what is not mentioned on the front page of the website (but is on the pdf) is that the authors work for Oracle and IBM so if you are going to wave it at people be prepared to answer any 'vested interest' counterclaims.
