Microsoft has published a press-release, announcing they will provide MS Office users with the option of saving documents in open document format (ODF):
With the release of Microsoft Office 2007 Service Pack 2 (SP2) scheduled for the first half of 2009, the list will grow to include support for XML Paper Specification (XPS), Portable Document Format (PDF) 1.5, PDF/A and Open Document Format (ODF) v1.1.
When using SP2, customers will be able to open, edit and save documents using ODF and save documents into the XPS and PDF fixed formats from directly within the application without having to install any other code. It will also allow customers to set ODF as the default file format for Office 2007. To also provide ODF support for users of earlier versions of Microsoft Office (Office XP and Office 2003), Microsoft will continue to collaborate with the open source community in the ongoing development of the Open XML-ODF translator project on SourceForge.net.
Microsoft will join the Organization for the Advancement of Structured Information Standards (OASIS) technical committee working on the next version of ODF and will take part in the ISO/IEC working group being formed to work on ODF maintenance.
ODF Alliance called the announcement in a special press release, “Because Microsoft has a history of broken promises, no one should celebrate this news until we see what is actually done and how quickly it is put in place.”
