Dashamir Hoxha has posted version 0.7.1 of DocBook Wiki, an open source Wiki that can display and edit DocBook documents online. Editing can be done in text, HTML, or XML but the data is always stored in DocBook XML which is automatically converted to other formats when served to browsers.
I'v ebeen thinking a lot about Wikis lately. One thing that has always turned me off about them is the reliance on weak plain text, when I really want to see (and receive) well-formed markup. I wonder what would happen if I uploaded the original DocBook source for Processing XML with Java into a DocBook Wiki? Almost all of the book is still fairly up to date, but there are a few bits and pieces here and there I'd like to futz with; and it would be nice to cover XOM as well. (XOM was mostly invented out of my experience writing Processing XML with Java). I wonder if the authoring environment here is clean enough to get me (or others) to do that work? I don't have time to do this right now, but I think I will add it to my TODO list.
