NAME

       HTML::Microformats::Format - base microformat class

DESCRIPTION

       HTML::Microformats::Format cannot be instantiated directly but many other classes inherit
       from it.

   Constructors
       The constructors cannot actually be called on this package. Call them on descendent
       classes instead.

       "$object = HTML::Microformats::Format->new($element, $context, %options)"
           Parse a microformat with root element $element.

       "$object = HTML::Microformats::Format->extract_all($element, $context, %options)"
           Find and parse all such microformats within element $element.

   Public Methods - Accessors
       There are a number of property accessor methods defined via Perl's AUTOLOAD mechanism.

       For any microformat property (e.g. 'fn' in hCard) there are get_X, set_X, add_X and
       clear_X methods defined.

       "get_X": for singular properties, returns the value of property X. For plural properties,
       returns a list of values if called in list context, or the first value otherwise.

       "set_X": for singular properties, sets the value of property X to the first given
       parameter.  For plural properties, sets the values of property X to the list of
       parameters.  This feature is deprecated and will be removed in a future release.

       "add_X": for singular properties, sets the value of property X to the first given
       parameter, but croaks if X is already set. For concatenated singular properties,
       concatenates to the end of any existing value of X. For plural properties, adds any given
       parameters to the list of values of property X.  This feature is deprecated and will be
       removed in a future release.

       "clear_X": removes any values of property X, but croaks if the property is a required
       property.  This feature is deprecated and will be removed in a future release.

       For example, an HTML::Microformats::hCard object will have a method called get_fn which
       gets the value of the hCard's "fn" property, a method called set_fn which sets it, a
       method called add_fn which also sets it (but croaks if it's already set), and a method
       called clear_fn which croaks if called (because "fn" is a required property).

       Deprecated features: the "set_X", "add_X" and "clear_X" methods are deprecated and will be
       removed soon. In general you should treat objects which are instances of
       HTML::Microformats::Format as read-only.

   Public Methods - Other
       "$object->format_signature" or "$class->format_signature"
           This method may be called as a class or object method. It returns various information
           about the definition of this microformat (e.g. what is the root class, which
           properties exist, etc). You may need to do some digging to figure out what everything
           means.

       "$object->profiles" or "$class->profiles"
           This method may be called as a class or object method. It returns HTML profile URIs
           which indicate the presence of this microformat.

       "$object->context"
           Returns the parsing context (as supplied to "new").

       "$object->data"
           Returns a hashref of object data. This is a reference to the live data inside the
           object. Any changes to the returned hashref will change the values inside the object.

       "$object->element"
           Returns the root element.

       "$object->cache"
           Shortcut for "$object->context->cache".

       "$object->id([$trine_obj], [$role])"
           Returns a blank node identifier or identifying URI for the object.

           If $trine_obj is true, the return value is an RDF::Trine::Node object. Otherwise, it's
           a string (using the '_:' convention to identify blank nodes).

           If $role is undefined, then returns the identifier for the object itself.  If it's
           defined then it returns an identifier for a resource with a fixed relationship to the
           object.

             $identifier_for_business_card  = $hcard->id;
             $identifier_for_person         = $hcard->id(undef, 'holder');

       "$object->add_to_model($model)"
           Given an RDF::Trine::Model object, adds relevant data to the model.

       "$object->model"
           Creates a fresh, new RDF::Trine::Model object, containing relevant data.

       "$object->serialise_model(as => $format)"
           As "model" but returns a string.
