=head1 NAME
HTML::Microformats::Format::XMDP - the XMDP microformat
=head1 SYNOPSIS
use HTML::Microformats;
use LWP::Simple qw[get];
use RDF::TrineShortcuts;
my $uri = 'http://microformats.org/profile/hcard';
my $html = get($uri);
my $doc = HTML::Microformats->new_document($html, $uri);
$doc->assume_all_profiles;
my @xmdp_objects = $doc->objects('XMDP');
foreach my $xo (@xmdp_objects)
{
print $xo->serialise_model(
as => 'Turtle',
namespaces => {
rdfs => 'http://www.w3.org/2000/01/rdf-schema#',
hcard => 'http://microformats.org/profile/hcard#',
},
);
print "########\n\n";
}
=head1 DESCRIPTION
HTML::Microformats::Format::XMDP inherits from HTML::Microformats::Format. See the
base class definition for a description of property getter/setter methods,
constructors, etc.
HTML::Microformats::Format::XMDP also inherits from HTML::Microformats::Format::XOXO, and
the C<data> method returns the same structure.

=head1 MICROFORMAT
HTML::Microformats::Format::XMDP supports XMDP as described at
L<http://gmpg.org/xmdp/>.
=head1 RDF OUTPUT
Data is returned using RDFS.
=head1 BUGS
A limitation is that for any E<lt>ddE<gt> element with
E<lt>dlE<gt> children, only the first such E<lt>dlE<gt>
is looked at. This means that the XFN 1.1 profile document
is only partially parsable; most other microformat profile
document can be properly parsed though.
Please report any bugs to L<http://rt.cpan.org/>.
