The Opendocument format used by the OpenOffice.org suit has become an ISO standard. As always microsoft is creating its own standard based on xml called the Office XML. I really hate it when people fork things at least when there is no significant difference in the goals - It's mere waste of energy - now somebody has to provide the Office XMl to/from ODF converter. I appreciate that this time around M$ has at least placing their specifications open. Only last week I was blaming about their proprietary formats which made it unfit for batch processing. Life is more fun when things are open - World, Open up!
