While deciding on the topic it is recommended to talk to your supervisor.

Option 2:

Develop an RDF(S) ontology (or a dictionary) on a chosen topic (to be agreed upon with the teacher) and write a short report (max 5 pages) explaining the details of your work.

Explain every aspect of your ontology. Explain the assumptions underlying your ontological choices.

The ontology should not exceed 30 classes and 30 instances. The modeling language should be Turtle or a similar syntax. You can use any modeling software.
