I object to this strongly -- that syntax is neither reader friendly 
nor actually a part of the recommendation.  Much more importantly, we 
should be creating fragments that people can cut and paste into their 
documents (and edit) -- forcing them to figure out the mapping from 
the so-called human readable syntax into actually RDF or OWL (XML or 
N3) makes no sense.

I advocate use of "turtle" - which should be the first document this 
WG approves as a working note (if Dave is willing)

what is parser friendly?

well, we could get into whether this is a voting issue for a WG (be 
careful when you use words like "majority" in a W3C group) but my 
vote is for N3 (Turtle) which is a nice compromise - or else to stick 
w/the RDF/XML for cut and paste reasons
p.s. Mike - have you noticed our world view doesn't always seem to align :->
