NAME

       HTML::Microformats::Format::XFN - the XFN microformat

SYNOPSIS

        use Data::Dumper;
        use HTML::Microformats::DocumentContext;
        use HTML::Microformats::Format::XFN;

        my $context = HTML::Microformats::DocumentContext->new($dom, $uri);
        my @links   = HTML::Microformats::Format::XFN->extract_all(
                          $dom->documentElement, $context);
        foreach my $link (@links)
        {
          printf("<%s> %s\n", $link->get_href, join(" ", $link->get_rel));
        }

DESCRIPTION

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

   Additional Public Methods
       "$xfn->subject_hcard"
           Returns  the hCard for the subject of the relationship. e.g. if Mary has parent Sue, then Mary is the
           subject.

           If the subject could not be determined, may return undef.

       "$xfn->object_hcard"
           Returns the hCard for the object of the relationship. e.g. if Mary has parent Sue, then  Sue  is  the
           object.

           The  person  that is the object of the relationship may not have an hCard on this page, or the parser
           may not be able to determine the correct hCard, in which case, may return undef.

MICROFORMAT

       HTML::Microformats::Format::XFN  supports  XHTML  Friends  Network  1.0   and   1.1   as   described   at
       <http://gmpg.org/xfn/1>   and  <http://gmpg.org/xfn/11>;  plus  the  relationship  profile  described  at
       <http://purl.org/vocab/relationship/>;   and   XHTML   Enemies    Network    1.0    as    described    at
       <http://xen.adactio.com/>.

       By  default,  only XFN 1.1 is parsed, but if the context has profiles matching the other URIs above, then
       the other vocabularies are supported.

RDF OUTPUT

       Data is returned using the DERI's XFN vocabulary (<http://vocab.sindice.com/xfn#>) and when  appropriate,
       Ian  Davis'  RDF  relationship vocab (<http://purl.org/vocab/relationship/>) and Toby Inkster's XEN vocab
       (<http://buzzword.org.uk/rdf/xen#>).
