(I am using this page to begin a discussion that I hope will become the development plan (and eventual budget) for the ESIP Exchange. As of now, these are the comments of one person. (Howard Burrows 18:09, 20 January 2006 (EST)) This plan is based on a book by Jim Conallen entitled "Building Web Applications with UML Second Edition". In addition, it adopts elements of the Federal Enterprise Architecture (see Guide to FEA and e-Gov Site).)


We will construct the ESIP exchange using a collection of interrelated "reference models" as employed by the US Government in the Federal Enterprise Architecture:

The most important aspects of our development strategy are shown on the left and right of the diagram. Construction will be driven by the "business" of the Federation as described in our Federation Documents. The result will follow a component-based architecture.

In addition, we will be performance-driven and will design-to-test (DTT).



Developing the ESIP Exchange will involve a number of interations through the following five steps:

Vision Document

The full vision document should list:

Focus: (for us improved quality, use, and appreciation for Earth science)
Stakeholders (not just users)
  • Primary*: Foundation, Federation, Partners
  • Secondary*: Earth scientists, modelers, decision tool providers, decision makers, education
Scope
Incremental stages to desired end
Components
esipfed.org, GCMD, ECHO, GOS2, ESG, CLASS, NOMAD...

Requirements

Glossary
Functional Requirements
Specify and prioritize elements in Federation Mission
Nonfunctional Requirements
Performance, Security, Hardware
Use Cases
Key scenarios raised to family of similar cases
Tests
Each requirement will be defined in terms of a test that would show success

Analysis and Design

This step depends on the evolving requirements and will involve managers and the implementors: Atlantic BT, NGDC, ESRI, etc. Budget contingencies be part of the design documentation.

Implementation

This will involve staged implementation conducted by recruiting already_existing components:

Deployment

All components are already deployed with varying levels of use. Advertising and marketing the integrated ESIP Exchange will take place for targeted communities based on tests at each stage of integration involving sample audiences.
