OpenDocument/PDF in Massachussetts and the definition of "Open"
http://www.eweek.com/article2/0,1895,1884775,00.asp
I've been keeping up with the OpenDocument/PDF battle in that state. One thing that I have never understood is that if PDF is acceptable, why isn't MSWord. They are both perceived to be propietary formats controlled by a single vendor. MSWord has probably 10-100x the market acceptance of PDF based on the number of documents and the amount of work that goes into a particular MS Word document.
This just shows that the definition of words is truly whatever you want them to be. For me, the sheer volume of MSWord documents shows that it is accepted as a standard. The definition of Open: "There is a documented API to do that action, somewhere."
In this case, market acceptance has driven a standard. The world is full of plenty of technology standards that were never accepted in the marketplace. Unless, MSWord supports it, OpenDocument will be another technology standard that is not accepted in the marketplace for the next 18-24 months.
