- rdf_exporter.py: add isinstance(format, str) guard before .lower() so non-string inputs (None, int, etc.) raise ValidationError consistently instead of AttributeError; normalize via strip().lower() in one step - 15_Export.ipynb: fix notebook cell using result['valid'] → result['overall_valid'] (validate_rdf() returns overall_valid, not valid); add trailing EOF newline - test_rdf_exporter.py: add tests for non-string format → ValidationError and for overall_valid key presence in validate_rdf() return value Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
