So whatever you may think of ooxml, we seem to be implementing it .odf-converter-integrator is an easy way to open Microsoft Office 2007 files (also called Office Open XML, .docx, .xlsx, and .pptx) with a high-quality conversion on any Linux or Windows system in any OpenOffice.org.
odf-converter-integrator uses the high-quality odf-converter code (which converts between Office Open XML and OpenDocument) as packaged by Novell and integrates it into the operating system. That means when you click on a .docx/.xlsx/.pptx file on a web page, in an email attachment, or your desktop, odf-converter-integrator springs into action, converts the .docx/.xlsx/.pptx to an .odt/.ods/.odp, and then automatically opens the new document in OpenOffice.org, StarOffice, Abiword, KWord, Gnumeric, Microsoft Office 2003, or whatever is your default ODF editor.
odf-converter-integrator is simply a little glue to overcomes the integration limitation of the Novell odf-converter, which cannot integrate into most editions of OpenOffice.org (such as the vanilla/Sun Microsystems edition, Fedora, OxygenOffice, and others).
Ive not tested any of the mentioned proejct yet, partly because there is no 64 bit version of odf-converter-integrator yet. I could of course just run it inside 32 bit linux inside a virtualbox or something...
