Define the requirements for the datadisplay capabilities of PRISM

Define low-end and high-end graphicsrelating to the PRISM visualization tools

Define the interfaces to the transformationprocessing library and to the data analysis part

Which graphic packages and visualization toolsare useful for PRISM and should be examined more closely regarding their features

Which resources (manpower!) are availablefor the data display part

Assign the lead responsibilities for the WP2c and WP4a deliverables
