=head1 DESCRIPTION

RDF::NS::Trine works like L<RDF::NS> but it returns instances of
L<RDF::Trine::Node::Resource> (or L<RDF::Trine::Node::Blank>) instead of
strings.

Before using this module, make sure to install L<RDF::Trine>, which is not
installed automatically together with L<RDF::NS>!

=head1 ADDITIONAL METHODS

=head2 BLANK ( [ $short ] )

Returns a new L<RDF::Trine::Node::Blank>.
