Introduction to the Exchange Network
• What is the Exchange Network?• How did we build it?• Why should you
care?

What is the Exchange Network?
HTTP servers using SOAP messaging and a common WSDL to enable synchronous and
asynchronous blah-blah, blah-blah...
An Internet and standards-based method for exchanging environmental information
between partners.
A common approach to sharing data that lets you use your partners’ data as if it is a part of
your own systems.

BMP Challenge:
• No standard template
• No set technology to deliver the data
• A requirement for data manipulation prior to modeling due to disparate spatial scales and processing discrepancies.
• Coordinated (federal and state) financial and business processes involved

The Exchange Network is
• A Federal, State, tribal and territorial partnership
• Jointly governed by its members
• Focused on Exchange, and only exchange
• Technology neutral

The Parts (your names may vary)
• Data Standards• Data Exchange
Templates (Schema)
• Trading Partner agreements
• Access protocols• Transport

Keys to success
• Set expectations early—no losers– Let’s talk Fork Length– An exchange standard is not a business rule
• Demonstrate success—extract value, and more will follow– Avoid perfection– Search for a visionary leader– Find a real world problem, big enough to me meaningful, small
enough to tackle

Potholes and Rabbit Trails
• “Let’s take this opportunity to solve world hunger”
• Confusing exchange standards with business practice standards
• Designing applications rather than exchanges
• “A comprehensive data warehouse”
