Justin submitted "Every few years a group of senior database researchers get together to do some self-assessment about the current state of database research and recommend new and future research areas. In the spring of this year there was such a meeting in Lowell, MA. It had been 5 years since the last meeting in Asilomar and from my point of view there had been significant achievements in the past years, so it would be interesting to see how the top of the database research field viewed these achievements and what they considered to be the next hot problems to be solved."
