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.
