PresentationML/DrawingML text import
One of the good things with being employed to work on a Free Software project like OpenOffice.org is that you can blog about it, since the code is publicly available. My day to day work is current PowerPoint 2007 import for Impress. This is a joint work between Sun and Novell.
A few weeks ago I implemented the text import from PresentationML (actually from DrawingML). It is far from perfect, but it is getting there. See the example:
It imports the text, the characters and paragraph properties, etc.
