Simulation / Evaluation

Data sets for driving pub/sub and event processing research
- For a start:
  - NYSE Data
Benchmarks for evaluating pub/sub and other event-based systems
- What are good performance metrics for pub/sub systems?
- What are realistic models for workload generation?
- What is a solid methodology for evaluating pub/sub systems?

Interoperability among pub/sub systems (e.g., agreed data formats for pub/sub)
- Can we connect Siena via Hermes and Rebecca to Elvin, Padres and ToPSS and others?
- For a start:
  - Advanced Message Queuing Protocol (AMQP) specifications (Version 0-9)
  - Elvin IETF Draft Specifications at http://www.elvin.org

Brainstorm on applications, testbeds, and large deployments
- How can we bring up a world-wide pub/sub network?
- Can we run a generic and public pub/sub system on PlanetLab?
- What are killer applications for distributed event-based systems?
  - How can event-based systems help build global sensor networks?
  - How can small-scale actuator/sensor networks (e.g., in an e-home scenario) profit from pub/sub?
Think about joint research efforts and projects between groups
- What sources of joint funding exist?

Identify research and engineering challenges in the context of pub/sub et al.
- What are exciting research challenges that the community should look at?
- What research topics have been neglected in the past?
- Unification - pub/sub is actually an overlay structure on delay-tolerant networks; need to explore the synergy of pub/sub and DTNs when modeled and implemented in this way
- One-size-fits-all usually fits nothing particularly well; in addition to sharing events across systems, we need to further explore how a PS system designed for constrained environments (e.g. sensor networks) can federate with PS systems designed that do not suffer from similar constraints.
How can we expand the DEBS community to include researchers from related fields?
- How do we relate to efforts in stream processing systems, event processing, software engineering, ...?
- How do we want to position ourselves as a community?
