NAME

RDF::TrineX::Parser::RDFa - RDF::Trine::Parser-compatible interface for RDF::RDFa::Parser

DESCRIPTION

While RDF::RDFa::Parser is a good RDFa parser, its interface is a tad... shall we say... crufty.

RDF::TrineX::Parser::RDFa provides a much nicer interface, and is a subclass of RDF::Trine::Parser, so you get super-polymorphic benefits. Yay!

Class Method

parse_url_into_model($url, $model, %args)

As per the method of the same name in RDF::Trine::Parser, this retrieves the URL and parses it into a model.

Unlike RDF::Trine::Parser, this method always assumes you're trying to parse some variety of RDFa.

Constructor

new(%options)

Constructs a new RDF::TrineX::Parser::RDFa parser.

The two important options are flavour (which defaults to 'xhtml') and version (which defaults to '1.1'). Other options are documented in RDF::RDFa::Parser::Config.

Let's imagine that you want to parse RDFa 1.1 in HTML5, and you want to also parse the role, longdesc and cite attibutes (which are not strictly part of RDFa, but nevertheless often interesting). Then you'd use:

  my $parser = RDF::TrineX::Parser::RDFa->new(
    flavour        => 'html5',
    version        => '1.1',
    role_attr      => 1,
    longdesc_attr  => 1,
    cite_attr      => 1,
  );

Object Methods

The following methods are supported, as documented in RDF::Trine::Parser.

parse_into_model($base_uri, $data, $model [,context => $context])

parse($base_uri, $data, \&handler)

parse_file_into_model($base_uri, $fh, $model [,context => $context])

parse_file($base_uri, $fh, \&handler)

The following additional methods are supported:

rdfa_flavour

Returns the RDFa host language being used.

rdfa_version

Returns the RDFa version number being used.

Subclasses

The following subclasses of RDF::TrineX::Parser::RDFa exist:

RDF::TrineX::Parser::XHTML_RDFa10

RDF::TrineX::Parser::HTML32_RDFa10

RDF::TrineX::Parser::HTML4_RDFa10

RDF::TrineX::Parser::HTML5_RDFa10

RDF::TrineX::Parser::XHTML5_RDFa10

RDF::TrineX::Parser::Atom_RDFa10

RDF::TrineX::Parser::DataRSS_RDFa10

RDF::TrineX::Parser::SVG_RDFa10

RDF::TrineX::Parser::XML_RDFa10

RDF::TrineX::Parser::OpenDocument_RDFa10

RDF::TrineX::Parser::XHTML_RDFa11

RDF::TrineX::Parser::HTML32_RDFa11

RDF::TrineX::Parser::HTML4_RDFa11

RDF::TrineX::Parser::HTML5_RDFa11

RDF::TrineX::Parser::XHTML5_RDFa11

RDF::TrineX::Parser::Atom_RDFa11

RDF::TrineX::Parser::DataRSS_RDFa11

RDF::TrineX::Parser::SVG_RDFa11

RDF::TrineX::Parser::XML_RDFa11

RDF::TrineX::Parser::OpenDocument_RDFa11

By using these classes, you can skip the need to pass the 'flavour' and 'version' options to the constructor. For example:

  my $parser = RDF::TrineX::Parser::HTML5_RDFa11->new(
    role_attr      => 1,
    longdesc_attr  => 1,
    cite_attr      => 1,
  );

Note that these are classes, but they are not modules. You should not attempt to load them with require or use.
