The battle between the OpenDocument Format and Microsoft's Open Office XML was long, and here and there rather nasty, but it appears as if we finally have a winner. The company behind OOXML already conceded by announcing it would implement support for ODF in Office 2007 SP2, but now it has also said it quite literally: ODF has won.
Microsoft's national technology officer, Stuart McKee, speaking at a panel at the Red Hat Summit in Boston, said:
ODF has clearly won. We sell software for a living. The ability to implement ODF in the middle of our ship cycle was just not possible. We couldn't do that during the release of Office 2007. We're looking forward and committed to doing more than [ODF-to-OOXML] translators.
