There is a lot of buzz currently around on how KDE and KOffice are blindly rejecting OOXML, and Gnome and Abiword/Gnumeric are blindly embracing it. I think this is a complete misunderstanding, and that the position of both projects isn’t that different, but due to some amplification effects, both position are seen as “extreme” in one or the other direction.
KOffice position is that ODF is and should be supported to be the standard for interoperability between office suite. So, the effort is concentrated on improving the specification, the implementation and ensuring that documents created by KOffice is correctly opened by other Office Suite (and vice-versa). KOffice position concerning OOXML is that, in its current version, it shouldn’t be made an international standard. The main reason is that OOXML isn’t build on pre-existing standard (like ODF for instance, or SVG or even dates…), which result in a huge specification.
But the need of our users is important, it’s very likely that, at some point, we will offer a way to import OOXML, most likely using one of the OOXML to ODF converter. But there is no urgency about this, as currently OOXML is an unfinished specification used by nearly nobody.
