For the VLDB collocated workshops at the Humboldt-Universität the organizers
provide a central registration point. The point will be in front of the "Senatssaal"
in the main building (see
http://www.vldb.informatik.hu-berlin.de/overview_hu_level1.htm). From the
main entrance you have to go upstairs and then you will see the registration
desks.
The DBISP2P workshop will take place in the same building as VLDB itself (Unter den Linden 6, 10099 Berlin), room 3088 (3rd floor).
