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-Item, which course a student participates in, and what items a student is interested in or has completed.

Student-Item 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.

Completed Items

Returns all items, that have been completed. And shows those who have been completed on a specified date in a timeline. (The rest is visible via the table-option of the graph widget.)

Completed Course Work

Returns all items, that are Course Work, i.e need to be completed in order to pass the course. Completed items are marked green and work, that is mandatory but has not been completed yet is marked red. (Completed items are items that a student links to using the has completed-Property.)

NOTE: Currently works without specific courses, meaning that the Course Works has not yet been attributed to a specific course. There is also no certification by a lecturer.

Prerequisites for a course

Gives an overview of all items, that are prerequisites to items that are included in a course. Those items themselves are not part of the course and can be seen as fundamental knowledge to be known before taking to course in question.

Fundamental knowledge to know before taking a couse.

NOTE: The definition of what is included in a course is currently not fully completed, but in theory the query should work.

Using the Graph yourself

If you want to visualize your own usage of the graph, try the queries down below. After clicking Try it! all you need to do is swap out the Item: Q157 with your own item's number Q... and query the graph (or press CTRL+ENTER).


A complete overview

Items used: Max Mustermann (Q157)


#defaultView:Graph
PREFIX wdt: <https://graphit.ur.de/prop/direct/>

SELECT ?item1 ?image ?item1Label ?item2 ?image2 ?item2Label ?edgeLabel WHERE {
  VALUES ?item1 {wd:Q157}
  
  ?item1 ?prop ?item2.
  ?edge ?dummy ?prop ; rdf:type wikibase:Property 
  
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
} ORDER BY ?prop

Try it!
