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:
$gen = RDF::RDFa::Generator::HTML::Head->new(%options);
Options include:
o base - the base URL where the output data will be published. This allows in some cases for the generated RDFa to include relative
URIs.
o data_context - if non-null, a URI (string) which indicates the context (named graph) containing the data to generate RDFa for.
o namespaces - a {prefix=>uri} hashref of preferred CURIE prefixes.
o ns - a {uri=>prefix} hashref of preferred CURIE prefixes. DEPRECATED - use namespaces instead.
o prefix_attr - use the @prefix attribute for CURIE prefixes (RDFa 1.1 only). Boolean, defaults to false.
o safe_xml_literals - prevents XML literals from injecting arbitrary XHTML into the output. Boolean, defaults to FALSE.
o title - assign a <title> element for generated XHTML documents.
o version - set generated RDFa version. Valid values are '1.0' (the default) or '1.1'.
Public Methods
"$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.
