Editing Create Export Plugins (section)

===Testing the Hello World plugin===

Save the ''HelloWorld.pm'' file and then restart the Web server, eg.:

 service httpd restart

'''Why do I need to restart the Web server?''' EPrints uses mod_perl which loads all Perl modules at start up; therefore whenever these modules change they need to be reloaded.

The Hello World export plugin handles lists of eprints and single eprints. Therefore, EPrints displays it in the list of export plugins on the search results page:

When the Hello World export plugin is activated, the ''convert_dataobj'' subroutine is applied to every item in the list to produce the result:
