Microsoft's latest interoperability pledge: How free is 'open' now?

More calls on Microsoft to open up even more

The absence of any such mention was not lost on Red Hat chief counsel Michael Cunningham, in a response posted to his company's Web site yesterday afternoon.

"Rather than pushing forward its proprietary, Windows-based formats for document processing, OOXML," Cunningham wrote, "Microsoft should embrace the existing ISO-approved, cross-platform industry standard for document processing, Open Document Format (ODF) at the International Standards Organization's meeting next week in Geneva. Microsoft, please demonstrate implementation of an existing international open standard now rather than make press announcements about intentions of future standards support."

But Linux Foundation board member and attorney Andrew Updegrove thought yesterday's announcement was about ODF, in a sense...for the way in which it skillfully omitted mention of it.

"With respect to ODF, it will be important to see what kind of plug ins are made available, how they may be deployed, and also how effective (or ineffective) those translators may be," Updegrove said yesterday, in a statement shared with BetaNews. "If they are not easy for individual Office users to install, or if their results are less than satisfactory, then this promise will sound hopeful but deliver little. I am disappointed that the press release does not, as I read it, indicate that Microsoft will ship Office with a 'save to' ODF option already installed. This means that ODF will continue to be virtually the only important document format that Office will not support 'out of the box."'

The fact that Microsoft's making any movement in this direction at all, Updegrove added, is an indication to him that "multiple market forces" -- which, he said, included the EC investigation and the popular uprising of ODF support -- "are pushing and pulling Microsoft in a direction that it would have been highly unlikely to travel otherwise."

Yesterday's statement from the European Commission apparently was intended to serve as a reminder to everyone, including Microsoft, that its definition of "interoperability" is deeper than the mere dissemination of APIs. It said its current investigations are focused on "the alleged illegal refusal by Microsoft to disclose sufficient interoperability information across a broad range of products, including information related to its Office suite, a number of its server products, and also in relation to the so called .NET Framework and on the question whether Microsoft's new file format Office Open XML, as implemented in Office, is sufficiently interoperable with competitors' products."

Microsoft's APIs, as defined yesterday, provide open access by software with other software for the purposes of sharing information and functionality -- which is actually the way professional developers typically understand APIs and interoperability to work. But the legal definition is often fuzzier, as indicated by the EC's reminder yesterday that Microsoft needs to make its OOXML file format -- as opposed to Office 2007, the software which utilizes the format -- "sufficiently interoperable."

That would require not an API as Ballmer describes it but a plug-in as Updegrove describes it. Microsoft has said it is participating with open, community efforts to produce such plug-ins, though critics continue to question why the company doesn't just produce one on its own. Backers of Microsoft's efforts pose the counter-argument that it shouldn't be Microsoft's responsibility to ensure one-to-one correlation between its own format and every other one that comes along, whether or not it's an international standard.
