Pedro Bizarro (Univ of Coimbra in Portugal) reported on the EPTS Use Case workgroup he co-chaired with Dieter Gawlick (Oracle CQL author). Their penultimate use case questionnaire runs to 52 questions, which they think is more than sufficient (or as Pedro said, “for some people, size matters”).
Next up were some uses cases using said template (currently available only to registered users of the EPTS web site):
- Alex from Betfair started the ball rolling with their fraud / “unfair use” usecase. An example of this is detecting where someone cancels a bet in advance of everyone else, because perhaps they have insider-based early access to information. This led to a spirited discussion with the capitalists in the audience who thought that “gaining an edge” was surely just part of the game (possibly missing that the betting exchange name is “Bet Fair”). Alex also presented a page of streaming SQL with the complaint that such an approach was unmaintainable (no arguments there).
- Arkady from Mitre then invented the meeting catchphrase, “spatio-temporal hyperspectral multi-resolution data grid”, for his description of applying CEP to data grids for operational analytics and event warehouses. He commented that this was a work in-progress, but I would have preferred to have seen the domain use case (i.e. what sorts of data and what sorts of event processing), not just the idea.
- Brian Connell (WestGlobal) actually presented a nice Mobile Operator Performance Monitor (i.e. BAM application), presenting it in the use case format. This provided operational intelligence for real-time views and decisions, sitting on top of TIBCO middleware as it happened.
- Dieter (Oracle) presented a “First Responder” application, which seemed like it might be a candidate for one of David Luckham’s “holistic event processing” applications. This apparently used (or would use) SensorML and NIEM with Common Alerting Protocol. This would use things like weather events to determine accurate evacuation orders during catastrophes.
- Guy Sharon from IBM Haifa [*1] presented on a use case for “Preservation and Maintenance Facility Safety”, namely using RFID to track-and-trace personnel and equipment and determine “unsafe situations”.
- Richard Tibbetts (Streambase) presented on Alternative Trading Systems (aka Dark Pool trading or Crossing Engine - which is simply doing in-brokerage trades with existing liquidity, while complying with normal market regulations, SLAs and pricing). Trades must still be completed within 10-15ms, but “indications of interest” are allowed for “possible buys”. They have 3 such customer cases with 1 actually deployed. Richard also used the use case format, so full marks there.

[1] IBM certainly outdid everyone else with their support for the EPTS meeting. There was the Amit R&D project, System S stream processor, Aptsoft, and Standards teams. With apologies to any IBM group I may have missed…
