A simple interface to www.scholix.org

Takes a PID, eg a DOI, passes this to the Scholix API for a list of related online resources.
Renders the results as an HTML list. Designed for easy inclusion in other pages via an ajax call.

Make sure you have the Perl LWP::UserAgent module installed either through CPAN or through a Linux package manager (RPM: perl-libwww-perl, DEB: libwww-perl).
Place the scholix cgi script in your repository, eg /opt/eprints3/archives/REPO/cgi/scholix
Then hook in an ajax call where you would like the data to be included, eg on the summary pages.

This is easily achieved by adding some code to eprint_render.pl eg

my $pid = $eprint->get_value("id_number");
if( $pid )
{
  $page->appendChild( $repository->make_element("div", id => "scholix") );
  $page->appendChild( $repository->make_javascript( "new Ajax.Updater( 'scholix', '/cgi/scholix', { parameters:'pid=$pid'}); ") );
}

Or as part of a citation, eg

<if test="is_set(id_number)">
  <div id="scholix"></div>
  <script>
    var scholix_pid = "<epc:print expr="id_number.as_string()"/>";
    new Ajax.Updater( 'scholix', '/cgi/scholix', { parameters:'pid='+scholix_pid });
  </script>
</if>
