NAME

       HTML::Microformats::Format::hCard - the hCard microformat

SYNOPSIS

        use HTML::Microformats::DocumentContext;
        use HTML::Microformats::Format::hCard;

        my $context = HTML::Microformats::DocumentContext->new($dom, $uri);
        my @cards   = HTML::Microformats::Format::hCard->extract_all(
                          $dom->documentElement, $context);
        foreach my $card (@cards)
        {
          print $card->get_fn . "\n";
        }

DESCRIPTION

       HTML::Microformats::Format::hCard inherits from HTML::Microformats::Format. See the base class definition
       for a description of property getter/setter methods, constructors, etc.

   Additional Method
       •   "to_vcard"

           This method exports the hCard as a vCard 3.0. It requires RDF::vCard to work, and will throw an error
           at run-time if it's not available.

       •   "to_vcard4"

           This method exports the hCard as a vCard 3.0. It requires RDF::vCard to work, and will throw an error
           at run-time if it's not available.

       •   "to_vcard4_xml"

           This method exports the hCard as a vCard XML. It requires RDF::vCard and XML::LibXML to work, and
           will throw an error at run-time if it's not available.

MICROFORMAT

       HTML::Microformats::Format::hCard supports hCard as described at <http://microformats.org/wiki/hcard>,
       with the following additions:

       •   vCard 4.0 terms

           This module includes additional property terms taken from the latest vCard 4.0 drafts. For example
           the property 'impp' may be used to mark up instant messaging addresses for a contact.

           The vCard 4.0 property 'kind' is used to record the kind of contact described by the hCard (an
           individual, an organisation, etc). In many cases this is automatically inferred.

       •   Embedded species microformat

           If the species microformat (see HTML::Microformats::Format::species) is found embedded within an
           hCard, then this is taken to be the species of a contact.

       •   Embedded hMeasure

           If the hMeasure microformat (see HTML::Microformats::Format::hMeasure) is found embedded within an
           hCard, and no 'item' property is provided, then the measurement is taken to pertain to the contact
           described by the hCard.

RDF OUTPUT

       Data is returned using the W3C's vCard vocabulary (<http://www.w3.org/2006/vcard/ns#>) with some
       supplemental terms from Toby Inkster's vCard extensions vocabulary (<http://buzzword.org.uk/rdf/vcardx#>)
       and occasional other terms.

       After long deliberation on the "has-a/is-a issue", the author of this module decided that the holder of a
       vCard and the vCard itself should be modelled as two separate resources, and this is how the data is
       returned. Some information about the holder of the vCard can be inferred from information about the
       vCard; for instance, the vCard's fn property can be used to determin the holder's foaf:name. This module
       uses FOAF (<http://xmlns.com/foaf/0.1/>) to represent information about the holder of the vCard.
