The section discussing the various language styles is based on the DEBS 2009 tutorial of the Event Processing Technical Society workgroup on language analysis co-chaired by Jon Riecke and Opher Etzion, with the following members: Adrian Paschke, Alex Kozlenkov, Arno Jacobsen, Bala Maniymaran, Bob Hagmann, David Tucker, Dermot McPeake, Francois Bry, Guy Sharon, Louis Lovas, Michael Eckert, Pedro Bizarro, Richard Tibbetts, Robert McKeown, Susan Urban, Simon Courtenage, and Serge Mankovskii.
