Hello Aliki, The graph http://www.openlinksw.com/schemas/virtrdf# contains system metadata about all RDF Views in use, including the default one that is used to store triples in DB.DBA.RDF_QUADS table. RDF_GLOBAL_RESET() does not make the table DB.DBA.RDF_QUADS (the default storage) entirely empty, it erases everything and then load the default content of http://www.openlinksw.com/schemas/virtrdf# .
