NAME

rdf/parser/trig - TriG parser.

SYNOPSIS

  from rdf/parser/trig import TriGParser;

  let quads := (new TriGParser()).parse_string("""
  @prefix ex: <http://example.com/> .
  ex:s ex:p "default graph" .
  GRAPH ex:g { ex:s ex:p "named graph" . }
  """);

DESCRIPTION

TriGParser parses RDF 1.1 TriG into RDF quads. It accepts default graph triples outside braces, wrapped default graph blocks, named graph blocks with or without the GRAPH keyword, and graph labels written as IRIs, prefixed names, or blank node labels.

Parser options are base, used to resolve relative IRIs, and into, used to load parsed quads directly into a store.
