NAME

6       RDF::Trine::Parser::Notation3 - Notation 3 Parser
7

SYNOPSIS

9        use RDF::Trine::Parser;
10        my $parser     = RDF::Trine::Parser->new( 'Notation3' );
11        $parser->parse_into_model( $base_uri, $data, $model );

DESCRIPTION

14       This module provides a Notation 3 parser for RDF::Trine.
15
16   Methods
17       This package exposes the standard RDF::Trine::Parser methods, plus:
18
19       "forAll($handler)"
20           Sets a callback handler for @forAll directives found in the top-
21           level graph. (@forAll found in nested formulae will not be passed
22           to this callback.)
23
24           The handler should be a coderef that takes a single argument: an
25           RDF::Trine::Node::Resource.
26
27           If you do not set a handler, a warning will be issued when this
28           directive are encountered in the top level graph, but parsing will
29           continue.
30
31       "forSome($handler)"
32           As "forAll" but handles @forSome directives.
33
34       "parse_formula($base, $input)"
35           Returns an RDF::Trine::Node::Formula object representing the
36           Notation 3 formula given as $input. $input should not include the
37           "{"..."}" wrappers.
38
39   Datatype Callbacks
40       The constructor accepts a hashref of callbacks associated with
41       datatypes, which will be triggered after a literal has been parsed with
42       that datatype.  Let's imagine that you want to replace all xsd:integer
43       literals with URIs like "http:;//example.net/numbers/123"...
44
45        my $parser = RDF::Trine::Parser::Notation3->new(
46          datatype_callback => {
47            'http://www.w3.org/2001/XMLSchema#integer' => sub {
48              my ($lit, $tr_hnd) = @_;
49              return RDF::Trine::Node::Resource->new(
50                'http:;//example.net/numbers/' . $lit->literal_value
51              );
52            },
53          },
54        );
55
56       Note the second argument passed to the callback $tr_hnd. We don't use
57       it here, but it's a coderef that can be called with
58       RDF::Trine::Statement objects to add additional triples to the graph
59       being parsed.
60
61       This facility, combined with shortcuts from
62       RDF::Trine::Parser::ShorthandRDF is pretty useful for creating domain-
63       specific languages.
