Additional Data for Page Editor Plugins

Page Overview

[Hide]

1 Initial Problem

The instance properties of Page Component Plugins are saved in the XML of the content page where an instance is created. This automatically supports copy and export/import by default and is suitable in many cases.

But some page plugins need to store more data, e.g. files, media or large data sets which would blow up the XML of a page. Examples:
  • A media plugin may support specific media types or playback modes.
  • Another page component plugin should make plugin question types available on learning module pages, e.g. the STACK question. The definition of such a question uses its own tables.
The problem comes when a page is coped or exported and imported. Then the additional content has to be treated, too.

2 Conceptual Summary

The ilPageComponentPlugin class should get an onClone() function with parameters for the old and the new page element. This function will be called when a plugin page component is copied and can be overridden by the plugin.

Page components plugins should be able to write additional data or files to the export of a page and should be able to import them when the page is imported. The implementation details have to be clarified with the maintainers of the COPage  and Export services.
