This page proves an overview of the API calls you can use to access the data in a DataObj.  The example framing this is that of an export plugin.

== The Plugin ==
 
An export plugin will look something like this:
 
<source lang="perl">
package EPrints::Plugin::Export::Text;
 
use EPrints::Plugin::Export::TextFile;
 
@ISA = ( "EPrints::Plugin::Export::TextFile" );
 
use strict;
 
sub new
{
        my( $class, %opts ) = @_;
 
        my $self = $class->SUPER::new( %opts );
 
        $self->{name} = "ASCII Citation";
        $self->{accept} = [ 'dataobj/eprint', 'list/eprint' ];
        $self->{visible} = "all";
 
        return $self;
}
 
 
sub output_dataobj
{
        my( $plugin, $dataobj ) = @_;
 
        my $cite = $dataobj->render_citation;
 
        return EPrints::Utils::tree_to_utf8( $cite )."\n\n";
}
