1. Plug-in API redesign
2. Remote execution: JavaGAT and Tomcat
3. Flow controller (full functionality: event handling, joint/split,…)

4. Platform support for Hadoop and ?MapReduce-like plug-ins

5. Performance and scalability assessment: metrics, tests, … (towards D5.5.3)
6. Implementation of Design Patterns
7. Other?
