Just for my own edification. Is it correct that N3 already includes a  
path syntax similar to the SPARQL property paths one, and plans to add  
expressions, so will require a delimiter, or is it a first one to  
stick their syntax flag in the ground situation?

It doesn't really alter my feelings on the subject, but the three way  
syntax land grab between turtle, N3 and SPARQL is not ideal. I don't  
really get the impression that there's any W3C policy in this area.
