Not quite. There is no implied CSV Direct Mapping to RDF triples.

Instead, the input CSV table is directly translated to a SPARQL solution set, which is also a table. The solution set can then be further manipulated using SPARQL filters, SPARQL bind, other SPARQL constructs, and then finally turned into a set of triples using a CONSTRUCT template.

Best,
Richard
