SPARQL 1.1 Query Language. This section defines the correct behavior for evaluation of graph patterns and solution modifiers, given a query string and an RDF dataset.
It does not imply a SPARQL implementation must use the process defined here. The outcome of executing a SPARQL query is defined by a series of steps, starting from the SPARQL query as a string, turning that string into an abstract syntax form, then turning the abstract syntax into a SPARQL abstract query comprising operators from the SPARQL algebra. This abstract query is then evaluated on an RDF dataset. 18.2 Translation to the SPARQL Algebra. The D2RQ Platform – Accessing Relational Databases as Virtual RDF Graphs.
