Exercises

NoteExercise 1: Comparing Storage Solutions

Task: Compare the different storage solutions offered by the University of Hamburg.

1. Visit the UHH Disk, UHH Cloud, Object Storage and Research Data Repository service pages

2. Discuss which solution would be most appropriate for different research scenarios:

   • Daily research work with frequent file access
   • Long-term archival storage
   • Collaborative projects with external partners
   • Large datasets requiring automated processing

NoteExercise 2: Exploring the Research Data Repository

Task: Familiarize yourself with the UHH Research Data Repository features.

1. Explore the repository features mentioned in the documentation:
   • Versioning system (Concept-DOI vs. Versions-DOI)
   • Citation export options
   • Metadata licensing
2. Discuss the importance of:
   • Long-term preservation (10+ years)
   • Multiple backup locations
   • Copyright and licensing considerations
3. Consider a research project from your field and determine:
   • What type of data would you publish?
   • What metadata would be essential?
   • Which license would be appropriate?
