Karl asks, "...How does one start hacking?" Although this might be politically incorrect advice, Toby Segarin's O'Reilly book "Programming the Semantic Web" (2009) (use The Google...) is a very accessible introduction. Two caveats: Python based (which for some of us is a selling point!) and there are a few places in the book where the editing is crap and misses critical lines of example code; you can readily figure these out by *understanding* what is going on. One or a few examples in particular leaves out key conneg code, ugh. Note that there is good online code now via Toby's site, I didn't use it when I went through it last year...
