Jean Goffinet pointed out that he and the folks working on the ODF to Open XML converter project now have a blog going up on the SourceForge site (http://odf-converter.sourceforge.net/blog/). In the latest post, Jean discusses the thinking that went into their decision to use C# and XSLT. I have to admit that I haven't had as much free time as I would like, and have missed out on some of the big developments that have happened so far in the project so it's nice they have the blog which should help me keep up to date.
I already pointed out two weeks ago that they reached the end of their first milestone and have really come a long way in such a short time. I'm glad that there are a number of easy ways now to follow their progress and read more about the decision decisions they've been making. It's all open source, so you can follow along and participate as much as you wish. I wish I had more time to get directly involved myself, but I at least want to make sure I'm available to help answer any questions (although the latest draft of the spec does a pretty good job on its own).
