NAME

       RDF::RDFa::Generator - Generate data for RDFa serialization

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, an Attean Blank or IRI object or an RDF::Trine::Node
               which indicates the context (named graph) containing the data to generate RDFa
               for.

           ·   namespacemap - a URI::NamespaceMap object containing preferred CURIE prefixes.
               This is the preferred method, see note below.

           ·   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, %opts)"
           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
           serializing 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 serialize 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)

           Options can also be passed as a HASH. This is typically used for style-specific
           options.

       "$gen->inject_document($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 serializing 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.

UPGRADING TO 0.200

       The recommended upgrade path is to migrate your application to use Attean rather than
       RDF::Trine as your RDF library. If that is not an option, you may continue to use
       RDF::Trine, by using a compatibility layer.  If you are using this module directly, to
       upgrade from earlier releases, you would simply add

        use RDF::TrineX::Compatibility::Attean;

       alongside the import of this module. It is in a separate distribution that needs to be
       installed. If you use the RDF::Trine::Serializer methods, you should instead use
       RDF::Trine::Serializer::RDFa.

NOTE

       Version 0.200 introduced a large number of changes to be compatible with both Attean and
       RDF::Trine. Some of these were backwards-incompatible, some were to support new features,
       such as the use of URI::NamespaceMap.

   Backwards-incompatible changes
       The methods "serialize_model_to_file", "serialize_model_to_string",
       "serialize_iterator_to_file" and "serialize_iterator_to_string" that were provided for
       compatibility with the RDF::Trine::Serializer interface have been moved to a module
       RDF::Trine::Serializer::RDFa that has to be installed separately to use this with
       RDF::Trine.

       "data_context" previously accepted a plain-text string URI. Now, it requires an
       appropriate object, as documented.

       Since RDF 1.1 abandons untyped literals, this module also ceases to emit them.

   Namespace mappings
       The way namespace mappings are handled have been rewritten. Now, the preferred method to
       add them is to pass an URI::NamespaceMap object to "namespacemap". This will override any
       other options.

       The namespace mappings for the following prefixes will always be added: "rdfa", "rdf",
       "rdfs" and "xsd".

       If URI::NamespaceMap is not used, but "namespaces" is given as a hashref of prefix-URI
       pairs, the pairs will be added. If neither are given, all mappings from RDF::NS::Curated,
       which includes all if RDFa Initial Context will be added. Finally, any pairs from the
       deprecated "ns" option will be added, but a warning will be emitted.
