On Monday September 24th, we organized the first international VLDB workshop on Management of Uncertain Data [dKvKD07]. The idea of this workshop arose a year earlier at the Twente Data Management Workshop on Uncertainty in Databases [dKvK06]. The TDM is a bi-annual workshop organized by the Database group of the University of Twente, for which each time a different topic is chosen. The participants of TDM 2006 were enthusiastic about the topic "Uncertainty in Databases" and strongly expressed the wish for a follow-up co-located with an international conference. To fulfill this wish, we organized the MUD-workshop at VLDB.
