Refactor Survey Export

1 Initial Problem

The survey export is using the legacy/unmaintained ilXmlWriter. Additionally the code is currently not well separated from the main survey class.

2 Conceptual Summary

The export should be refactored to a) use datasets b) get rid of ilXmlWriter c) provide proper validation.

9 Discussion

Schmitz, Tim [tschmitz], AUG 14, 2024: I very much support this improvement from the perspective of the Metadata component. Starting from ILIAS 11, LOM of an object can only be imported/exported as a tail dependency, and this is only possible for Survey Question Pools after its import/export is refactored. Without this refactoring, Survey Question Pools will thus lose their LOM after import in ILIAS 11 and above.

10 Implementation

{ The maintainer has to give a description of the final implementation and add screenshots if possible. }
