  2. Agenda • Brief summary of the Seminar • Session on future Research Directions • Follow-on activities

  3. Dagstuhl Center The Center promotes fundamental and applied research, continuing and advanced academic education, and the transfer of knowledge between those involved in the research side and application side of informatics. The key instrument for promoting research are the Dagstuhl Seminars, which bring together internationally renowned leading scientists for the purpose of exploring a cutting-edge informatics topic. The friendly and open climate at the conference center promotes a culture of communication and exchange among the seminar participants. The non-profit Center is a member of the Leibniz Association and is funded jointly by the German federal government and a number of state governments.

  5. Backgrounds/Interests of Participants • Active Databases • Rules-based Event Processing • Rewerse project • Streaming and Databases • Distributed Pub/Sub systems • Sensor networks and wireless • Simulation and Verification • High-end computation applied to Physics • Modelling • Business Activity Monitoring • Crisis Management • Ambient Intelligence (Smart Cities) • Unification/positioning of events, streams, databases

  6. Topics suggested for discussion • Three meta questions from Roy Schulte • a) What areas should research focus on? • b) What should industry do? • c) Is this a Paradigm shift? • Applications • Characterise application space for EP - scenarios, current and future • Benchmarks, good benchmarks. design points • EP Semantics • Semantics of events, temporal uncertainty, programmatic semantics • Streams and Event management • EP Modelling • Positioning of SOA, EDA and EAI • Differing models for event processing, also models for events and modelling notation • Relationship between Events and BI.. "Event pattern mining" • Rule management, Evolution of rules. Visualization of rules • Implementation • Scalability • Approaches to distributed event brokering, aspects, timing • Event acquisition. Control of sensor networks, Identification of time-critical events • Operational characteristics, "ilities", system guarantees, security • Others • Vertical Markets • Standards • Spam and false positives

  7. Application scenarios

  8. Example: Sessions on Tuesday • Graph Transformation approach to EP (Claudi Paniagua-Macia, IBM) • Analysis of the new SQL extensions (Carlo Zaniolo, UCLA) • EP models in physics, CERN and LOFAR (Tore Risch, Uppsala Univ ) • Snoop and its semantics (Sharma Chakravarthy, UTA) • Filters and Composite Events (Susan Urban, ASU) • Stream semantics (Jonathan Marsh, Microsoft) • Handling of uncertainty (Avigdor Gal , Technion) • Methods and Tools (Mikael Berntdsson, Skövde) • Business Activity Monitoring (Tobias Blickle, IDS Scheer) • Classification of events via WS-Topics (Peter Niblett, IBM) • Event Algebra (Annika Hinze, University of Waikato) • Business Performance Observation Model (Henry Chang, IBM)

  9. Suggested Research Directions

  10. Follow-up activities • A summary of the seminar and all the sessions is now available at http://kathrin.dagstuhl.de/files/Submissions/07/07191/07191.SWM1.ExtAbstract!.pdf • Short Term plans • Publish a summary in ACM SIGMOD RECORD • Start work to establish an EU Center of Excellence • “Management of Events in the Web” • Alex Buchmann, Francois Bry, Avi Gal • Add Event Processing terms to the Encyclopedia of Database Systems • Apply to form a new ACM SIG • Longer Term initiatives • Book of articles about EP • Portal with a collection of existing courses and other teaching materials • Decision on a possible Federated EP Conference • Special issue of a popular magazine (e.g. IEEE computer) and a scientific journal • EP summer school (perhaps funded by the EU center of excellence) • EP journal (handled as part of the ACM submission)
