• The lecture introduces XML and related standards and explains them using examples.
• There are exercises that deepen the students' understanding of the concepts introduced in the lecture.
• There will be question hours with the tutors spread over the time before the submission dates.
• The exercise mainly consists of programming tasks and accounts for 25% of the overall grade.
• In order to create the same prerequisites for submission for all students, there is a uniform submission date for all students followed by the submission interviews.
• During the submission interviews, the examples are checked for correctness, but especially for understanding, and feedback is given accordingly.

 *********Hybrid Teaching in SuSe22 ************
Due to the COVID-19 crisis, this course will use a hybrid approach to teaching, using the TUWEL platform as well as meetings with the students on campus. On a weekly basis the students will receive videos of lectures on all topics of the course. Furthermore, on a weekly basis we will have a discussion session in a lecture room, where the students and the teachers can discuss the lecture material (Q&A sessions; the first Q&A session is on March 9). Exercises will be managed using TUWEL, while the exercise discussions with tutors will be held online using Zoom. In addition, a discussion forum on TUWEL will be used to answer student questions and to clarify issues. 

The exam mode: written exam in the university campus. 

In case of COVID-19 restrictions that disallow events on campus, the following changes would be made to the organization of the lecture:

- the Q&A would be moved to online mode (Zoom meetings)

- the examination mode would be changed to "Online written exam on paper". In this mode, the examiners and the students are permanently connected via  audio and video in a online meeting. At the end of the exam, the students must scan  of the written exam and upload it to TUWEL within the time specified by the examiner (approx. 5 minutes).
