NAME

RDFStore::Parser::OpenHealth - This module implements an RDF strawman parser for the syntax proposed by Jonathan Borden at http://www.openhealth.org/RDF/rdf_Syntax_and_Names.htm

SYNOPSIS

	use RDFStore::Parser::OpenHealth;
        use RDFStore::NodeFactory;
        my $p=new RDFStore::Parser::OpenHealth(
		ErrorContext => 2,
                Handlers        => {
                        Init    => sub { print "INIT\n"; },
                        Final   => sub { print "FINAL\n"; },
                        Assert  => sub { print "STATEMENT - @_\n"; }
                },
                NodeFactory     => new RDFStore::NodeFactory() );

	$p->parsefile('http://www.openhealth.org/RDF/mns-fig13-result.xml');
        $p->parsefile('/some/where/my.xml');
        $p->parsefile('file:/some/where/my.xml');
	$p->parse(*STDIN);

	use RDFStore;
	my $pstore=new RDFStore::Parser::OpenHealth(
                ErrorContext 	=> 2,
                Style 		=> 'RDFStore::Parser::Styles::MagicTie',
                NodeFactory     => new RDFStore::NodeFactory(),
                store   =>      {
                                	persistent      =>      1,
                                	directory       =>      '/tmp/',
                                	seevalues       =>      1,
                                	options         =>      { style => 'BerkeleyDB', Q => 20 }
                                }
        );
	$pstore->parsefile('http://www.openhealth.org/RDF/mns-sect7.2-result.xml');

DESCRIPTION

This module implements a Resource Description Framework (RDF) strawman parser compliant to the syntax proposed by Jonathan Borden at http://www.openhealth.org/RDF/rdf_Syntax_and_Names.htm using the XSLT style sheet at http://www.openhealth.org/RDF/extract/rdfExtractity.xsl. Such a syntax is yet another extension/refinement of the original syntax proposed by Dan Connoly at http://www.w3.org/XML/2000/04rdf-parse/rdfp.xsl and already extended by Jason Diamond's at http://www.injektilo.org/rdf/rdf.xsl. The parser has been completely written in Perl using the XML::Parser::Expat(3) module. For the actual explaination see the RDFStore::Parser::SiRPAC(3) man page.

METHODS

RDFStore::Parser::OpenHealth supports all the RDFStore::Parser::SiRPAC options but Source. See the manual page for RDFStore::Parser::SiRPAC(3)

BUGS

Although the syntax proposed by Jonathan Borden is quite complete, the style-sheet is not unfortunately compatible with the Sablotron(3) great XSLT engine, that does not support 'exclude-result-prefixes' and functions overriding. A modified version working for Sablotron is available in the samples directory in the file xml2rdf.xsl.
