You wouldn't know it from reading Microsoft's press release, but it appears that even they have realized that "open" xml has not made it through this round of ISO certification. the door is not completely closed on the matter yet, but this is a pretty big win for free and truly open file formats. Congrats to everyone who worked on this, and a big huge "you immoral asshats, this is why people dislike you" to Microsoft for rigging votes around the world. I hope the ISO learns from this set of events (though i'm not particularly holding my breath on that one).
With a global community made aware of the issues, contributing to the solutions and communicating broadly even the most competitive and powerful of companies are finding it difficult to tread on our freedom and get the world to buy into their lies.
To everyone who supported "open" xml in the free / open source community (unfortunately there were some, including some fairly well known people), I really urge you to seriously think about your position on this matter. the name "open xml" is a lie because it isn't open (there have been more than enough highly technical articles written debunking that issue thoroughly), it's a danger to true file format standardization efforts (e.g. ODF) and an unnecessary complication for office apps in general. We can win this one in the long haul and move everyone to ODF, but it takes patience and determination. It also means adopting the long term view rather than the short term myopia that support of "open" xml represents. Microsoft has gone this route (non-binary formats, standardization, etc) specifically because of pressure from the free software community. we are starting to win this competition and they know it. The question is whether they will capitulate and join us or whether they can subvert the processes and communities just enough to keep in their old, anti-competitive and unethical ways upon which the bulk of their business model is currently based. By changing the rules so others have to either change or, by their own choices, exit the game we can make this industry more rewarding, more ethical and a better citizen in our world.
To everyone who spent days, weeks and months of their lives exposing "open" xml for what it truly is: congratulations, thank you and you have my deepest respect and gratitude. People from around and even outside the community rallied to make this happen. I'm also proud of how the koffice developers got involved and joined arms with many others in the software and standardization world. You people rock =)
