NAME

RDF::Trine::Parser - RDF Parser class

VERSION

This document describes RDF::Trine::Parser version 1.000

SYNOPSIS

 use RDF::Trine::Parser;
 
 RDF::Trine::Parser->parse_url_into_model( $url, $model );
 
 my $parser     = RDF::Trine::Parser->new( 'turtle' );
 $parser->parse_into_model( $base_uri, $rdf, $model );
 
 $parser->parse_file_into_model( $base_uri, 'data.ttl', $model );

DESCRIPTION

RDF::Trine::Parser is a base class for RDF parsers. It may be used as a factory class for constructing parser objects by name or media type with the "new" method, or used to abstract away the logic of choosing a parser based on the media type of RDF content retrieved over the network with the "parse_url_into_model" method.

METHODS

"media_type"
Returns the canonical media type associated with this parser.
"media_types"
Returns the media types associated with this parser.
"parser_by_media_type ( $media_type )"
Returns the parser class appropriate for parsing content of the specified media type.
"guess_parser_by_filename ( $filename )"
Returns the best-guess parser class to parse a file with the given filename.
"new ( $parser_name, @args )"
Returns a new RDF::Trine::Parser object for the parser with the specified name (e.g. "rdfxml" or "turtle"). If no parser with the specified name is found, throws a RDF::Trine::Error::ParserError exception.
 
Any @args will be passed through to the format-specific parser constructor.
 
If @args contains the key-value pair "(canonicalize => 1)", literal value canonicalization will be attempted during parsing with warnings being emitted for invalid lexical forms for recognized datatypes.
"parse_url_into_model ( $url, $model [, %args] )"
Retrieves the content from $url and attempts to parse the resulting RDF into $model using a parser chosen by the associated content media type.
 
If %args contains a 'content_cb' key with a CODE reference value, that callback function will be called after a successful response as:
 
 $content_cb->( $url, $content, $http_response_object )
"parse_into_model ( $base_uri, $data, $model [, context => $context] )"
Parses the $data, using the given $base_uri. For each RDF statement parsed, will call "$model->add_statement( $statement )".
"parse_file_into_model ( $base_uri, $fh, $model [, context => $context] )"
Parses all data read from the filehandle or file $fh, using the given $base_uri. For each RDF statement parsed, will call "$model->add_statement( $statement )".
"parse_file ( $base_uri, $fh, $handler )"
Parses all data read from the filehandle or file $fh, using the given $base_uri. If $fh is a filename, this method can guess the associated parse. For each RDF statement parses $handler is called.
"parse ( $base_uri, $rdf, \&handler )"
"new_bnode_prefix ()"
Returns a new prefix to be used in the construction of blank node identifiers. If either Data::UUID or UUID::Tiny are available, they are used to construct a globally unique bnode prefix. Otherwise, an empty string is returned.
