log:semantics

A built-in function for fetching RDF content off the web for processing.

{ <foo.rdf> log:semantics ?f } 
=> 
{ ?f a :InterestingFormula }.

For cwm, the named pages have to be in RDF/XML or N3. It uses Content-Type header and some heuristics.

Try squid and setenv http_proxy, if network performance is a problem.
