Wow, this looks really nice. One thing that isn't clear is how I get the information out. so for example, if I'm building a recommendation engine, is there some kind of api that my webapp can use to get the information (sorry, new to all this).
Right now Sense is best for ad-hoc interactive analysis and batch/scheduled jobs. You can run long-running services that expose something like a REST endpoint, but we have plans to make exposing services much easier, so I'd probably hold off until we have an "official" solution.
