Firstly, what is OpenXML? Well, it's the underlying document format in Office 2007. Market researchers with the Burton Group have issued a 37-page study– not commissioned by Microsoft or any other tech vendor — that finds Microsoft’s OOXML document format to be more useful than the rival ODF format backed by Microsoft’s competitors.
After comparing the respective merits of OOXML and ODF, Burton made its recommendations for IT managers:
“Any organization directly or indirectly (e.g., exchanging files with business partners) using Microsoft Office applications should plan to exploit OOXML. In addition to being the default file format in Office 2007, OOXML offers significant compression and security advantages relative to earlier, binary Microsoft Office file formats.
“Although moving to OOXML file formats involves some administrative challenges, the opportunities for improved content management and productivity outweigh the short-term inconvenience of migrating from binary file formats.”
