> There is some initial work on RDF Query, is there? The only kind of query stuff that I've worked with is CWM [1]. I thought it might be nice to come with an example EARL file that could be processed (based on Len's interpretation of assertions vs. Charles, converting one to the other):- :c a :comment; :author :len; :commentObject :apple; :commentString [ :color "green" ] . Now, if we used a log rules file for that:- <> log:forAll :x , :y , :z , :c . { c: a :comment; :author :x; :commentObject :y; :commentString :z . } log:implies { :x :asserts { :y :comment :z . } . } . It (should) give the following output on CWM, pending my inevitable mistakes:- :len :asserts { :apple :comment [ :color "green" ] . } . So you see that CWM is a kind of simple query engine, but note that it can't yet make inferences. Still, this should be quite useful to give examples with. Basically, given :x :y :z, you can make any sort of rule up concerning those variables. [1] http://www.w3.org/2000/10/swap/cwm.py -- Kindest Regards, Sean B.
