....more advanced optimization strategies like cross media optimization or optimization driven materialization. Further, neither format independence nor the irreversibility problem are addressed. Within the AMOS project at GMD IPSI a concept called presentation independence has been developed [14]. This abstraction aims at optimizing pre orchestrated presentations for differently equipped clients. The QoS of such a presentation automatically adapts to the client s facilities at run time. There are, however, no operations for ad hoc creation or modification of presentations. Thus, the ....

....and concepts considered in the following paragraphs only have minor commonness with VirtualMedia. Hence, they are examined less detailed than the E ADT approach. 20 Related Work SFB 501 A3 Within the AMOS project at GMD IPSI a concept called presentation independence has been developed [RKN96]. The focus here is on separating the content and logical structure of a presentation from the management of the quality of service (QoS) That means, the content and logical structure of a presentation can be defined independently from the physical representation of the media data. The actual QoS ....

....more advanced optimization strategies like cross media optimization or optimization driven materialization. Further, neither format independence nor the irreversibility problem are tackled. Within the AMOS project at GMD IPSI a concept called presentation independence has been developed [RKN96]. This abstraction makes the details of adaptive QoS management [Thi98] transparent to the application. We believe that this could be optimally realized on top of transformation independence (or VirtualMedia, for that matter) Commercial ORDBMSs (available, e.g. from Informix, IBM, and Oracle) ....
