• Selection
   – What are good criteria for selecting parts of graphs?

• Synchronization
   –   How do you know the original dataset has changed?
   –   How does this work for a partial replica?
   –   What is the optimal unit of change?
   –   Is SPARQL the optimal interaction protocol?
• Target result: efficient and effective replication
  methods for several replication scenarios
1. Overview
 1. Literature study
 2. Definition of replication scenarios
 3. Development of evaluation methodology
2. Iterative approach
 1. Implement data replication pipeline
 2. Evaluate results
• Evaluating selection criteria
 –   Size
 –   Analysis: graph structure
 –   Retrieval: precision and recall
 –   …
• Evaluating synchronization efficiency
 – Bandwidth usage
 – Replication latency
