Ah right, thanks, I seem to have missed this.

Hmm, must confess I'm in two minds. For true human-legibility a total 
replacement certainly is better, but something along the lines of  my 
suggestion would keep most of the key parts of the RDF machine-readable 
in the interchange syntax, while the tasty part (the interface 
definition itself) is human readable directly, machine readable given a 
little translation. Of course pretty much any syntax can be used 
locally, and translated at the end points, so it's not a big deal in any 

The choice of a Lisp-like syntax is interesting. Who the target audience 
for this? If it's 'old school' krep folks, then it's bound to do well. 
However if the aim is to get web developers to use it, then I'd 
anticipate resistance, and would have thought swapping the braces for 
angle brackets (a la OWL Presentation Syntax) would be good politics ;-)

But on both points, given that work that has already been done on the 
surface syntax I'd lean towards the current approach.
