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.
       CAUTION: If you parse more documents into one model, you need to set distinct BNodePrefix
       (see below) for each document. This way you avoid mixing anonymous resources from distinct
       documents together.

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
       o   new(%options)

           Available options are

           o   Assert

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

           o   BaseURI

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

           o   BNodePrefix

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

           o   InlineURI

               Deprecated.

       o   parse($string)

       o   parseFile($fileName)

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

       Keys are:

       o   subject_ns, subject_name, subject_uri

           namespace, local value and URI of subject

       o   predicate_ns, predicate_name, predicate_uri

           namespace, local value and URI of predicate

       o   object_ns, object_name, object_uri

           namespace, local value and URI of object, if the object is a resource

           or

       o   object_literal, object_lang, object_datatype

           object value for literal, it's language and datatype
