Hmm... I've changed it to produce that for now, but I'm not sure I
understand what this new and improved URI is supposed to represent.  Does
this mean that I have to make my own namespace so that this can be
translated into something meaningful later?  Is this supposed to be able to
retrieve the results? (Sorry, I'm still new to this whole earl/rdf thing,
so my questions will tend to be kind of basic.)

Oops. :) I basically copied my output from ATR, as you guessed.  You should
make "Learning EARL by Example" public, it's quite helpful.

><http://www.w3.org/Style/CSS/Test/CSS1/current/test17.htm> :id "1.7" .

That's kind of cool.  I'm going for easy to produce and easy to parse here.
 I'll play around maybe.

Would it be worthwhile to produce EARL in n3 too?

Another place where I wasn't sure of the purpose of the resource.  I'm not
sure what's supposed to be there.

Actually the script uses POST by default, but it accepts either.  The one
call with GET for the sub-frame is an exception because it was the only way
I could think of to pass on state information when I couldn't force the
form to submit itself. (I'm new to cgi scripting too, is there a better way
to do this?)  I wanted to avoid having to save any information to the server.

What's suitable?

Hmm... Network?  Nullifier?  Node? :)

Thanks for all your help with the EARL.  I'll work on fixing things up more.
