  • Each student will hold a short presentation (10 minute) on a subject not related to the group project in the course.
  • In addition short questions on the lecture are required to be answered by mail each week.
  • (The main part of the grade is made up by the group project.)


After the course the student is expected to be able to:

  • describe and explain the concept of open data,
  • explain the necessary elements of open data,
  • understand the different license types of open data,
  • know how open data is provided in Germany and other countries,
  • know how open data can be used by citizens, organizations and businesses.

Tutorial (Übung)

The tutorial consists of a group project based on open data and realized with open source software. The project is documented in a short final report after the presentation.

This includes:

  • defining a specific project starting out from a generally defined subject
  • finding the proper data,
  • conceiving design and appropriate software model,
  • developing and realizing (at least) a prototype.

Results are presented in the final session (23.07.2014).
