OK, I got log:semantics wrong above... your example here makes more sense 
to me.

So log:semantics says that its object is the graph you get by dereferencing 
and parsing as RDF/N3 the resource identified by the subject?  In which 
case, the equivalence would be:

   ex:someName :- { (some set of triples) }

   ex:docName log:semantics { (some set of triples) }

would be equivalent to:
   ex:docName log:semantics ex:someName

by my understanding of :- here.
