NAME

       RDF::RDFa::Generator - generate some data in RDFa

DESCRIPTION

   Constructor
       "$gen = RDF::RDFa::Generator->new(style => $style, %options)"
           Creates a new generator object. $style is one of the following case-sensitive strings:
           'HTML::Head' (the default), 'HTML::Hidden' or 'HTML::Pretty'. You can also construct
           an object like this:

             $gen = RDF::RDFa::Generator::HTML::Head->new(%options);

           Options include:

           •   base - the base URL where the output data will be published. This allows in some
               cases for the generated RDFa to include relative URIs.

           •   data_context - if non-null, a URI (string) which indicates the context (named
               graph) containing the data to generate RDFa for.

           •   namespaces - a {prefix=>uri} hashref of preferred CURIE prefixes.

           •   ns - a {uri=>prefix} hashref of preferred CURIE prefixes. DEPRECATED - use
               namespaces instead.

           •   prefix_attr - use the @prefix attribute for CURIE prefixes (RDFa 1.1 only).
               Boolean, defaults to false.

           •   safe_xml_literals - prevents XML literals from injecting arbitrary XHTML into the
               output. Boolean, defaults to FALSE.

           •   title - assign a <title> element for generated XHTML documents.

           •   version - set generated RDFa version. Valid values are '1.0' (the default) or
               '1.1'.

   Public Methods
       "$gen->create_document($model)"
           Creates a new RDFa file containing triples. $model is an RDF::Trine::Model object
           providing the triples. Returns an XML::LibXML::Document object suitable for
           serialising using its "toString" method.

           If you're planning on serving the RDFa with the text/html media type, then it is
           recommended that you use HTML::HTML5::Writer to serialise the document rather than
           "toString".

           Can also be called as a class method:

            $document = RDF::RDFa::Generator->create_document($model)
            # Same as:
            # $document = RDF::RDFa::Generator->new->create_document($model)

       "$gen->inject_document($document, $model)"
           Injects an existing document with triples. $document is an XML::LibXML::Document to
           inject, or a well-formed XML string. $model is an RDF::Trine::Model object providing
           the triples. Returns an XML::LibXML::Document object suitable for serialising using
           its "toString" method.

           See "create_document" for information about serving the RDFa with the text/html media
           type.

           Can also be called as a class method. See "create_document" for details.

       "$gen->nodes($model)"
           Provides triple-laden XML::LibXML::Elements to be added to a document.  $model is an
           RDF::Trine::Model object providing the triples. If called in list context, returns a
           list of XML::LibXML::Element objects which can be added to a document; otherwise
           returns an XML::LibXML::NodeList containing a list of such elements.

           Can also be called as a class method. See "create_document" for details.

           The HTML::Pretty generator can be passed a couple of additional options:

             $gen->nodes($model, notes_heading=>'Additional Info', notes=>\@notes);

           The notes are a list of RDF::RDFa::Generator::HTML::Pretty::Note objects which are
           added as notes to the end of each subject's data.

       Additionally the methods "serialize_model_to_file", "serialize_model_to_string",
       "serialize_iterator_to_file" and "serialize_iterator_to_string" are provided for
       compatibility with the RDF::Trine::Serializer interface.
