=head1 NAME

Bio::Annotation::Reference - Specialised DBLink object for Literature References

=head1 SYNOPSIS

    $reg = Bio::Annotation::Reference->new( -title => 'title line',
					    -location => 'location line',
					    -authors => 'author line',
					    -medline => 998122 );

=head1 DESCRIPTION

Object which presents a literature reference. This is considered to be
a specialised form of database link. The additional methods provided
are all set/get methods to store strings commonly associated with
references, in particular title, location (ie, journal page) and
authors line.

There is no attempt to do anything more than store these things as
strings for processing elsewhere. This is mainly because parsing these
things suck and generally are specific to the specific format one is
using. To provide an easy route to go format --E<gt> object --E<gt> format
without losing data, we keep them as strings. Feel free to post the
list for a better solution, but in general this gets very messy very
fast...

=head2 as_text

 Title   : as_text
 Usage   :
 Function:
 Example :
 Returns : 
 Args    :


=cut

sub as_text{
   my ($self) = @_;

   # this could get out of hand!
   return "Reference: ".$self->title;
}


=head2 hash_tree

 Title   : hash_tree
 Usage   :
 Function:
 Example :
 Returns : 
 Args    :


=cut

sub hash_tree{
   my ($self) = @_;
   
   my $h = {};
   $h->{'title'}   = $self->title;

}

=head2 tagname

 Title   : tagname
 Usage   : $obj->tagname($newval)
 Function: Get/set the tagname for this annotation value.

           Setting this is optional. If set, it obviates the need to provide
           a tag to Bio::AnnotationCollectionI when adding this object. When
           obtaining an AnnotationI object from the collection, the collection
           will set the value to the tag under which it was stored unless the
           object has a tag stored already.
 Example : 
 Returns : value of tagname (a scalar)
 Args    : new value (a scalar, optional)


=cut

sub tagname{
    my ($self,$value) = @_;
    if( defined $value) {
	$self->{'tagname'} = $value;
    }
    return $self->{'tagname'};
