# NAME

RDF::Core::Parser - RDF Parser

# DESCRIPTION

A module for parsing XML documents containing RDF data. It's based on XML::Parser. Parser goes through XML and calls what is referenced in Assert option for each statement found.

# SYNOPSIS

      require RDF::Core::Parser;

      my %options = (Assert => \&handleAssert,
                     BaseURI => "http://www.foo.com/";,
                     BNodePrefix => "genid"
                    );
      my $parser = new RDF::Core::Parser(%options);
      $parser->parseFile('./rdfFile.xml');
      #or
      $parser->parse($rdfString);

## Interface

- `new(%options)`
Available options are

- Assert
A reference to a subroutine, that is called for every assertion that parser generates.

- BaseURI
A base URI of parsed document. It will be used to resolve relative URI references.

- BNodePrefix
Blank node identifier is generated as ``_:'' concatenated with BNodePrefix value concatenated with counter number. Default BnodePrefix is ``a''.

- InlineURI
Deprecated.

- `parse($string)`
- `parseFile($fileName)`

## Assert handler

Assert handler is called with key value pairs in a parameters array.

Keys are:

- subject_ns, subject_name, subject_uri
namespace, local value and URI of subject

- predicate_ns, predicate_name, predicate_uri
namespace, local value and URI of predicate

- object_ns, object_name, object_uri
namespace, local value and URI of object, if the object is a resource

or

- object_literal, object_lang, object_datatype
object value for literal, it's language and datatype
