-Restart your web server and perform a search.
+Remember you must always '''restart your web server''' when you change perl code in EPrints to reload the perl. Alternatively you can call bin/epadmin reload <archive_id>.
 If all is well your plugin should appear in the dropdown menu. Select it and click export. As long as the search provided some results, you should get a list of EPrint titles returned.

 This method handles the export of each DataObj. DataObjs make up most of the content of an EPrint repository. The three main types are EPrint defining individual eprints, Document defining collections of one or more files belonging to an EPrints, and User which defines users of the repository.
-Besides an implicit reference to the Plugin object, this method is also provided with a reference to an individual DataObj. It is called by several [http://en.wikipedia.org/wiki/Common_Gateway_Interface CGI] and command line scripts to export single DataObjs, for instance the item control screen for repository staff. It is also called by the list handling method on each DataObj in a list, for example the results of a search. That will be explained in [[Contribute:_Plugins/ExportPluginList|the next tutorial]].

 In the example below we get the title of each DataObj, but there are large number of fields which you can extract from each DataObj. For example try changing "title" to "abstract" to print the abstract of each eprint.
