Using the R2RML method of generating semantic RDF triples in Oracle 12c
One model successfully created without any problems but then moved to a bigger one and were able to generate around 3,500 of the mapped triples into the staging table before it runs into an error when we call sem_apis.export_rdfview_model:
Error starting at line : 1 in command -
model_name => 'PLM_R2RML_TEST_MODEL',
rdf_table_owner => 'SEMANTIC',
rdf_table_name => 'PLM_R2RML_TEST_MODEL_TPL'
