Dutch government threatens to sideline Microsoft - here's a report from macworld (and the original Dutch report which i cannot read). One of the important feature about open file formats is that they are open. The consequence is that the contents will always be accessible in the future, even when the software that was used to open, edit and save those formats is long gone. Now despite Microsoft naming their new file formats OpenXML, the file formats are not open. In fact despite their efforts to pack ISO committees world-wide, Microsoft have so far failed to get their 6000 page partial description of the OOXML standard approved. If you are interested in a detailed description of MS activities, and issues to do with OOXML, here is the GrokDoc Dirty Tricks page and a summary of links (Groklaw).

What is evident is that there are half-truths being peddled, and MS are seeking to maintain user lock-in to their popular Office suite of applications: Office 2007 uses the new OOXML formats (e.g. docx). However the Open Document Format, being open (!), does not lock the user into any specific software package. It may, of course lock some packages out until such time as the software writers add odf filters.
