"As you can observe in these examples, Turtle defines several ways to specify IRIs in a result. Please, consult the specification for further details. As an overview, IRIs can be:\n",
" * *relative IRIs*: IRIs resolved relative to the current base IRI. Thus, you should define a base IRI (@base <http://example.org>) and then relative IRIs (i.e. <#spiderman>). The resulting IRI is <http://example.org/spiderman>.\n",
" * *prefixed names*: a prefixed name (i.e. foaf:Person) is transformed into an IRI by concatenating the IRI of the prefix (@prefix foaf: <http://xmlns.com/foaf/0.1) and the local part of the prefixed name (i.e. Person). So, the resulting IRI is <http://xmlns.com/foaf/0.1/Person\n",
" * *absolute IRIs*: an already resolved IRI, p.ej. <http://example.com/Auto>."
