Abstract
This paper describes extensions to the Tioga flight­simulator browsing protocol presented by
Stonebraker et al. (1993a). These extensions allow users to navigate a multidimensional data space
using sophisticated zooming capabilities. This design also allows users to move easily between
different multidimensional spaces. Tunneling between different data spaces is shown to be a
substantial generalization of hyperlinks in a hypermedia system. Finally, our design provides for
the coordination of multiple browsers. This preserves context and allows users to explore multiple
paths simultaneously.
