7

SYNOPSIS

9           my $element = DublinCore::Element->new( \%info );

11           print "qualifier: ", $element->qualifier(), "\n";

DESCRIPTION

16       DublinCore::Record methods such as element(), elements(), title(), etc
17       return DublinCore::Element objects as their result. These can be
18       queried further to extract an elements content, qualifier, language,
19       and schema. For a definition of these attributes please see RFC 2731
20       and <http://www.dublincore.org>.

25
26   content()

28
29           ## extract the element
30           my $title = $record->element( 'title' );
31           print $title->content();
32
33           ## or you can chain them together
34           print $record->element( 'title' )->content();
35

47
48   is_empty()
49       Gets and sets the "empty" status of an element. This is useful when
50       using DublinCore::Record's element() method.
51
52       To see if the record has an creator elements:
53
54           if( $record->element( 'creator' )->is_empty ) {
55               # no creators
56           }
57
58   set()
59       This function overrides the default set() behavior in order to remove
60       the is_empty flag.
