Test file for the SWI-Prolog RDF parser. Toplevel predicates:
# test/0
Run all tests from the `suite' directory and validate the
the result if the correct result is stored in a .ok file.
# suite(N)
Run test on suite/t<N>.rdf, showing RDF, intermediate
representation and triples on the console.
# passed(N)
Parse suite/t<N>.rdf and save the result in suite/t<N>.ok
The intention is to write tests, use suite/1 to make sure they are
parsed correctly and then run passed/1 to save the correct answer, so
running test/0 can validate all results.
