What is a category link?

A "category link" is an ILIAS object that you can use to create "links" within ILIAS. You probably know this function of the "link" from using your own laptop or desktop PC (see excursus).

Excursus: How the "link" works on a laptop or desktop PC
You want to place a program or folder in a specific location on your hard disk (internal memory of your device). For example, programs or apps are often stored on your hard disk under "C:Software". However, this location is deep within the system and can only be reached by several mouse clicks. This is where many people help themselves with a "link" for the object. You then place the link on your desktop view. In this way, you can quickly access what you want with just one mouse click, even though the desired object/software application is not directly saved on the desktop.

What can the category link be used for?

A category link can be used if you want to integrate an existing category (e.g. "Bachelor of Science XY") at several places on the ILIAS platform. Instead of always creating copies of the category you can use the category link to refer to a category centrally. This has the advantage that you only have to administrate and maintain the content in the category at one place (e.g. making corrections in texts) and not several times in the copies of the category.
