The Hypennedia '93 is the fourth in a series of Hypertext/Hypennedia conferences that have taken place in Basel, Dannstadt, and Graz. All these conferences--including the Hypennedia '93--were jointly organized by the respective Special Interest Groups of the Infonnation Technology Associations of Austria (OCG), Gennany (GI), and Switzerland (SI). The tenn hypermedia--as it is used at the present time--stands for infonnation that is organized with links that connect portions of infonnation. At the same time, hyper media signifies that these infonnation portions may be of an arbitrary medium type like text, graphics, image, sound, video, or executable code. We also refer to 'pure' hy pertext and to 'pure' multimedia as hypennedia. The former is of a uniform medium type, namely text, and the latter may be arranged in a strictly linear way, i.e. without links. Because we consider hypertext and multimedia as special cases of hypennedia, we have called this conference simply 'Hypermedia'.
