Microsoft holds firm against ODF

Despite the recent approval of the Open Document Format for Office Applications (ODF) by the International Organization for Standardization (ISO), Microsoft Corp. remains stalwart in its decision to forego support of ODF in its Office productivity suite, a company executive said this week.

Rather than support ODF, Microsoft is instead focusing on making XML the default file format for Office 2007, the next version of the suite that is due out later this year, said Chris Capossela, corporate vice president of Office marketing for Microsoft.

"Job one is moving to an XML-based file format, making that 100 percent compatible with every office document ever created," he said.

Microsoft's XML file format of choice is Microsoft Office Open XML, which will become the default file format for Microsoft Word, Excel and PowerPoint documents in Office 2007, Capossela said.

Microsoft wants to see Office Open XML become the international standard for office documents and submitted the technology to European standards body Ecma International in November. Ecma published the first draft of Open XML online last week. Ecma approval can help fast-track a technology through the standards process of the ISO, an international consortium that works with the United Nations to maintain and approve international technology standards.

The trouble with Microsoft's ultimate goal for Open XML is that earlier this month, the ISO approved Open XML's rival, ODF, as an international standard. The OpenDocument Foundation released soon after the approval a plug-in for Office that will allow it to access and save in ODF.

Companies including Microsoft rivals Sun Microsystems Inc., Adobe Systems Inc. and IBM Corp. are hoping ODF will become the international standard instead. They said approval by the ISO paves the way for adoption of office suites that support ODF, such as Sun's own StarOffice and others, in favor of Microsoft Office.

Some analysts think the same thing, and Gartner Inc. even published a news analysis after the ISO approved Open XML that called the move a "blow to Microsoft." The analyst firm said it's not likely the ISO will approve more than one XML-based standard for office document formats.

Capossela said that Microsoft customers are more interested in backwards compatibility between Office 2007 and older versions of the suite than they are in seeing ODF become a file format. Microsoft does not see ODF's approval by the ISO as a roadblock to customer upgrades to Office 2007, he said.
