Hi Benjamin,
The error was due to typo in the documentation:
rdfs_rule_set ('urn:owl.tests', 'http://vocab.org/relationship') ;
should be:
rdfs_rule_set ('urn:owl.tests', 'http://vocab.org/relationship/') ;
Note the "/" on the end of the graph name.
The online documentation has been fixed ...
Best Regards
Hugh Williams
