ExampleStudent

This is an examplatory page for student Max Mustermann's course of study. Max Mustermann is a prototype of a student-item and can be used to view a possible approach to use GraphIT.

A Student

A Student in the graph is defined as an item, that uses a students name or prefered alias/nickname as a label, as seen below.

Language	Label	Description
English	<Name>	Student at University of Regensburg (<Name>)

The item itself needs 'further specifications, such as a declaration that it is an instance of the Student, which Course a student participates in, what items a student is interested in or has completed. As seen below:

<Name>	— instance of →	Student
Student-Item	— interested in →	Item
Student-Item	— has completed →	Item
Student-Item	— participates in →	Course, Session

Using the Graph

Here are visual examples of how Max uses the graph. All used queries are made accessible in the next section.

A complete overview

Returns an entire overview of all items connected to Max.

.

Learnpath to interests

Returns the immediate dependencies for all items that Max is interested in.

Using the Graph yourself
