We used the data in many of our publications. They include several waves of longitudinal social networks of 11- to 17-year-olds in German schools. Networks are rather large, covering multiple classrooms rather than single ones. Minority youth are oversampled, thus allowing rather fine-grained analyses.
In addition, the data include measures of national, ethnic & religious identities, perceived discrimination, intergroup attitudes, and more.
Here’s a paper on (parts of) the identity measure: https://mda.gesis.org/index.php/mda/
