Add “no entry” node to taxonomy tree to show questions without taxonomy entries in questions pools

1 Initial Problem

Extensive question pools quickly become confusing. ILIAS offers the possibility to assign questions to one or more taxonomy nodes. For example, a question could be assigned to a chapter in the course (the taxonomy node would then be "Chapter"). Questions can belong to several taxonomy nodes (e.g. the additional node "Difficulty"). In this way it is possible to search for all difficult questions of a given chapter. However, the previous filtering options lack the possibility to filter for questions that do not yet have an entry in a corresponding node (e.g. have not yet been assigned to a chapter). If the assignment is missed during the creation of the question or if the taxonomy is extended by a node, it is very difficult to find the questions that have not yet been assigned.

2 Conceptual Summary

The already existing taxonomy filtering could be supplemented by the selection "no entry".

Could alternatively be resolved via Move Question Table in Question Pool Test to new UI Data Table.

3 User Interface Modifications

3.1 List of Affected Views

• … { Please list titles of all views (screens) of ILIAS that should be modified, newly introduced or removed. }

3.2 User Interface Details

{ For each of these views please list all user interface elements that should be modified, added or removed. Please provide the textual appearance of the UI elements and their interactive behaviour. }

3.3 New User Interface Concepts

{ If the proposal introduces any completely new user interface elements, you might consult UI Kitchen Sink in order to find the necessary information to propose new UI-Concepts. Note that any maintainer might gladly assist you with this. }

3.4 Accessibility Implications

{ If the proposal contains potential accessibility issues that are neither covered by existing UI components nor clarified by guidelines, please list them here. For every potential issue please either propose a solution or write down a short risk assessment about potential fallout if there would be no solution for the issue. }

4 Technical Information

{ The maintainer has to provide necessary technical information, e.g. dependencies on other ILIAS components, necessary modifications in general services/architecture, potential security or performance issues. }

5 Privacy

{ Please list all personal data that will need to be stored or processed to implement this feature. For each date give a short explanation why it is necessary to use that date. }

6 Security

{ Does the feature include any special security relevant changes, e.g. the introducion of new endpoints or other new possible attack vectors. If yes, please explain these implications and include a commitment to deliver a written security concept as part of the feature development. This concept will need an additional approvement by the JourFixe. }
