Rob Weir made a simple comparison between Microsoft’s OOXML and the current ISO standard ODF [via Truth Happens]. Both of these are file formats used when saving documents from office suite applications (e.g. MS Office 2007 saves in .docx format, OO.o Writer saves in .odt format). The purpose of having an open standard format is so that when someone creates a document using one application, it can be successfully opened and edited using a different application. Although ODF is the current standard set by an independent international organization, Microsoft is pushing to make their OOXML “another standard”.
