Info Page: QR Code for Permanent Links

1 Initial Problem

Entering URLs on mobile devices to quickly access any point in ILIAS is cumbersome. Almost all of them include a QR reader in there camera application which makes it easy to access a perma link once the QR code is available.

2 Conceptual Summary

The QR Code featue should be activated in the adminstration. The activation screen should already offer a QR code for the whole installation. Each info page should include the QR code representing the permanent link of the corresponding repository object. Each QR code presentation should offer a "Download QR Code" link to quickly enable the download and re-use for example in documents being disseminated to students.

Outlook (not part of this feature request):

There are other features which could re-use a QR code e.g. for providing contact data of students or tutors or QR Code to improve the protection against forgery of certificates or QR-Code for calendar export.

3 User Interface Modifications

3.1 List of Affected Views

• Administration > Repository > QR Codes
• Info Page

3.2 User Interface Details

Administration > Repository > QR Codes

• A new settings screen will contain a form and a Checkbox "QR Code for Permanent Links".
• Once activated a QR code will be presented underneath the form.

• Once activated, Info Pages will contain a QR Code underneath the current "Permanent Link" presentation.
• A link "Download QR Code" will  be presented underneath the QR code.

3.3 New User Interface Concepts

A new KS element "QR Code" should be implemented. It basically receives a string as input and renders a corresponding PNG or SVG as output.

4 Technical Information

The implementation will use a PHP QR code library. php-qrcode seems to be a well maintained option. In general there are several PHP QR Code libraries so that a general lock-in/dependency risk is small.

2019-04-15, Klees, Richard [rklees]: I really like this!

JourFixe, ILIAS [jourfixe], 24 APR 2019 : We highly appreciate this suggestion and schedule it for 6.0. A general setting for enabling / disabling QR codes is not necessary. Client side rendering of QR code could be considered if is more feasable. Please provide a related PR for a KS element "QR Code" (labeling needs to discussed afterwards due to possible legal issues).
