The development of the DLV system has started as a research projectfinanced by FWF (the Austrian Science Funds) in 1996,and
has evolved into an international collaboration over the years. Currently, the University of Calabria and TU Wien participate
in the project, supported by a scientific-technological collaboration between Italy and Austria. At the time of writing, the
latest version of the system has been released on April 12, 2002.
This work was supported by FWF (Austrian Science Funds) under the projects Z29-INF and P14781, by MURST under project COFIN-2000
“From Data to Information (D2I),” and by the European Commission under project IST-2002-33570.
