What you will learn

  • What an export plugin does, and how to write a simple, text-based example
  • How to ensure your plugin is compatible with different installations of EPrints (single and multiple repository)
  • Testing the plugin
  • Creating associated files and compiling the plugin
  • Sharing the plugin with the EPrints community and keeping it up to date

    • changing directories
    • listing contents of folders
    • copying, moving and editing text files
    • restarting the web server
