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.) -- adam Uche Ogbuji wrote: >>Pondering RDF Path: >><http://lists.w3.org/Archives/Public/www-rdf-rules/2003Sep/0001.html> >> >>Sean's page also provides some useful links on rdf path languages.
