Does The Document Foundation Support OOXML?
Soon after the release of LibreOffice 3.3, the Steering Committee posted their position on OOXML support in LibreOffice. Some of those that have tested the LibreOffice office suite knows that they can open and save in Microsoft Office formats. So, The Document Foundation supports OOXML then? Well, no, not really.
According to a new foundation wiki page, The Document Foundation does not support OOXML. It states the foundation supports only Open Standards such as the OpenDocument Format (ODF). But if users can read and write to Microsoft Office documents, isn't that OOXML support?
The foundation explains that the formats used in Microsoft Office, called OOXML, are not the same thing as the ISO standard of the same name. In fact, they quip "it is unclear whether anyone is able to implement the ISO standard."
