I am sure this can be done but I prefer not to think about the effort;). 
Even if we ignore the effort such an implementation would be server 
technology specific (say php, jsp...) and wont be reusable. Consider the 
case of changing something in tcdl or making that rdf in future ;). In 
other words I am saying that if we decide to spend time to make such a 
"tcdl authoring tool" we should better make it "forward compatible". 
Thats why I am proposing xforms. Alternatively I would also be happy to 
have a very simple form and ask people to submit everything in a zip 
file. Maybe this could be at least a good start.

I have already asked Derk (from bentoweb) as CarlosV proposed. I will 
let you know about any feedback.

Thanks for the feedback. I am sure we need to play a bit with style for 
making this better. But lets take a first evaluation feedback to see if 
there is any chance to make that accessible.;)
