.ie n .IP """$xfn\->subject_hcard""" 4
.el .IP "\f(CW$xfn\->subject_hcard\fR" 4
.IX Item "$xfn->subject_hcard"
Returns the hCard for the subject of the relationship. e.g. if Mary has parent Sue, then
Mary is the subject.
.Sp
If the subject could not be determined, may return undef.
.ie n .IP """$xfn\->object_hcard""" 4
.el .IP "\f(CW$xfn\->object_hcard\fR" 4
.IX Item "$xfn->object_hcard"
Returns the hCard for the object of the relationship. e.g. if Mary has parent Sue, then
Sue is the object.
.Sp
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.
.SH "MICROFORMAT"
.IX Header "MICROFORMAT"
HTML::Microformats::Format::XFN supports \s-1XHTML\s0 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/>;
