What is the Exchange Network?An Internet and standards-based method for
exchanging environmental information between partners
Design Principles:1. Stewardship of specific data will be
handled by mutual agreement between 2 or more trading partners
2. Stewards, through their nodes, are directly responsible for the quality and availability of this data
3. Network members, whose use of stewarded data necessitates the maintenance of local copies, are responsible and accountable for ensuring the integrity and currency of those copies
4. Network members agree to use the Network technology standards
3
Data Transfer Nodes(Web Services)
Nodes Hardware and software used to
exchange information on the Network
Use the Internet, a set of protocols, and appropriate security to respond to authorized requests for information
Send the requested information in a standard format, XML
Each partner has only one Node
4
Data Exchange Templates/XML Schema
Data Exchange Templates Describe format of data being
exchanged
Consist of XML schema
Draw upon data standards
Potential to reuse XML schema modules
Schema are developed for each exchange type (e.g., Discharge
Monitoring Report data)
5
Trading Partner Agreements
TPAs are made between exchange partners
Identify data exchange frequency
Identify exact data types/fields exchanged
Uses XML schema

What is the end result? Using the Exchange Network
Better quality data being exchanged States/EPA working closely to adopt new standards Data Standards embedded in XML Schema Machine to machine exchanges
More data can be exchanged among new partners State to state exchanges already occurring
Infrastructure can be applied to new data exchange types States share successes, promote reusability More timely data
Data can be published and exchanged as soon as partners agree Cost Savings reported by states
