[det]rdf_process_turtle(+Input, :OnObject, +Options)

Streaming Turtle parser. The predicate rdf_process_turtle/3 processes Turtle data from Input, calling OnObject with a list of triples for every Turtle statement found in Input. OnObject is called as below, where ListOfTriples is a list of rdf(S,P,O) terms for a normal Turtle file or rdf(S,P,O,G) terms if the GRAPH keyword is used to associate a set of triples in the document with a particular graph. The Graph argument provides the default graph for storing the triples and Line is the line number where the statement started.

call(OnObject, ListOfTriples, Graph:Line)

This predicate supports the same Options as rdf_load_turtle/3.

Errors encountered are sent to print_message/2, after which the parser tries to recover and parse the remainder of the data.

See also: This predicate is normally used by load_rdf/2 for processing RDF data.
