Hi,

This error means that the 'http://test.org/codifa.owl#glutine' entity is mentioned in your SPARQL rules but it does not exist in the world in which you execute the rule. There is either an error in the IRI in the rule, or you forgot to load the appropriate ontology in the right world.

individuals = on.individuals()

      next(individuals) # 1
      next(individuals) # 2
      Farmaco = next(individuals) # 3

         <''' + Farmaco.iri + '''> onto:lattosio ?g .
         <''' + Farmaco.iri + '''> onto:glutine ?s . }''')
      for col in row:
          if col==0:
             f2=row[col]
          if col==1:
             d2=row[col]
