Office Open XML http://www.microsoft.com/interop/msnovellcollab/open_letter.mspx Novell engineers have been working for the last year together with Microsoft engineers through the ECMA TC45 working group in producing a complete specification that would allow for interoperability across office suites. Novell will develop the code necessary to bring support for Office Open XML into OpenOffice, and we will contribute that support back to the OpenOffice.org organization. We will also distribute the Office Open XML plug-in in our own edition of OpenOffice. In addition, we will participate in the Open XML Translator open source project.
