Overview

Construction of the Earth Information Exchange will be driven by the "business" of the Federation as described in our Federation Documents. The result will follow a component-based architecture.

We have divided the use cases into two sections, one showing use of the Exchange to address areas of societal need, and the other showing the interface and underlying components. Eventually, it might be useful to construct a collection of interrelated "reference models" as employed by the US Government following the sections of the Federal Enterprise Architecture.

The most important aspects of our development strategy are shown on the left and right of Figure 1.

Applications Use Cases

It will be the scenarios that are created by each cluster that will drive the resource allocation. See the individual cluster pages at the top of the Main Page.

(These are just now coming under development in a way that will be useful in desgning and evolving the Exchange.)

Systems Use Cases

(currently only some of the use cases have been converted to Wiki format, the remainder are Word documents)
