Re: RDF Path languages

It also misses RxPath (understandably, since it didn't exist at the 
time) . RxPath maps RDF's abstract syntax to the XPath data model and is 
syntactically identical to XPath 1.0.  It was in large part inspired by 
Versa -- I liked the ideas of versa but wanted something more, well, 
xpath-like -- and is implemented on top of 4Suite.

see http://rx4rdf.liminalzone.org , in particular 
http://rx4rdf.liminalzone.org/RxPathSpec for a formal specification.

(But unfortunately there seems to be a problem with the router one hop 
away from my server and parts of the internet can't access this site 
right now.)
