I've added in EulerGUI an example showing how to apply rules about other rules.
main N3 file:
In rule r3 I'm trying to compare triples inside antecedent, but it doesn't work as I expect.
Another issue is that attempts to get the variable name do not work.
Advices are welcome ...
The implementation of log:notEqualTo is simply a "not unify"
and will fail when the arguments are not bound
(in Prolog speak: X = y succeeds, hence X \= y fails).
Best regards, Jos
OK; in N3 speak, ?X log:equalTo ?Y always succeeds when the variables ?X and ?Y are not bound,
because the underlying Prolog unification always succeeds when the Prolog variables X and Y are not bound.
This brings me back to another question.
If I want to match unbound variables coming from a log:implies,
and because log:equalTo cannot work, I need to
access the variable name. I tried log:uri , log:rawUri and e:label , but none
I'm afraid that variable names are not kept in Euler ...
Or is there a hope ?
