Revision of Logging in Test: Refactoring and Migration

1 Initial Problem

Currently, the test logs certain interactions of participants and lecturers through a static function in a concrete form in the database. Administrators can choose the language used for logging. The logging is not systematic and lacks structure, it is thus very hard to talk about it and thus to figure out what is logged and what isn't.

We discussed the actual state of Logging in the ILIAS Test based on a paper (see below) written by Kergomard, Stephan [skergomard] at the Feature Workshop 14 SEP 2023. We agreed that a revision is needed. This feature request treats the interface overhaul. (FR for interface overhaul).

We discussed the actual state of Logging in the ILIAS Test at the Feature Workshop 14 SEP 2023 and the paper (see below) Kergomard, Stephan [skergomard] wrote. We agreed that a revision is needed. This feature request treats the refactoring and migration.

2 Conceptual Summary

We propose:

• The introduction of separate logger-classes for different interactions (refactoring). There are going to be four types of "real" test interactions that are logged: TestAdministrationInteractions, TestQuestionAdministrationInteractions, TestParticipantInteractions, TestMarkingInteractions. Additionnally a TestError-Logger will be introduced to make it possible to gather all information from the ILIAS-Logging-System inside the test and thus to remove the need to look into the "normal" ILIAS-Log in case of errors.
• The abstraction of the log entries themselves, i.e. we don't log a text in a language, but a machine-readable representation that we can then convert into a text for the reader. This assumes that logging is not for archiving, as it implies the need to keep e.g. user information on the system to be able to resolve the ID of a user to her username or given name. Who wants to archive the log for long-term keeping, needs to export it.

Current Logging-Information will not and cannot be migrated to the new format. We will offer a function to download old log data as CSV for one ILIAS version, before removing all traces of it from the system.

3 User Interface Modifications

3.1 List of Affected Views

There is a separate Feature Request detailing changes to the interface we would like to implement simultaniously to this refactoring. This refactoring directly leads to two changes:

• The addition of a download button for the old logging entries under Administration > Repository and Objects > Test and Assessment > Log Data > Log Data Administration
• The removal of the option to set the Reporting Language under Administration > Repository and Objects > Test and Assessment > Log Data > Settings

3.2 User Interface Details

3.3 New User Interface Concepts

No new interface concepts are introduced.

3.4 Accessibility Implications

No accessibility implications are expected.

4 Technical Information

Technical Information can be found in the linked paper above.

5 Privacy

This change has privacy implications as some special data is collected here, but as in and of itself this feature will not change what data is collected, any changes will be discussed in the above mentioned FR here.

6 Security

This FR should improve security a tiny little bit, as interfaces become clearer and our code more understandable.
