1. 1 The National Environmental Information Exchange Network History and Overview Office of Water National STORET/WQX User Meeting November 27, 2007

2. 2 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. Principles: 1.Each partner manages their own data, and is the steward for data they originate. 2.The Network “doesn't care” how a partner manages and stores information. 3.Partners who need to store copies of data locally are responsible for the design, format, and maintenance of the copy they create. 4.Network partners agree to use adopted technology and data standards.

3. 3 Why? High demand for access to environmental information among partners Multiple approaches to information exchanges are inefficient and burdensome States modernizing information systems and migrating away from use of EPA national systems Use of integrated information technologies and approaches is on the rise Yesterday’s Answer for Today’s question

4. 4 Business Case: Water Monitoring ~30% of water monitoring data ever sees the light of day. Discoverable, Searchable Many failed efforts had focused on data consolidation, technology standards, and (always) a big database. Large investments in competing technologies. Cost of participation was too high for small organizations.

5. 5 The “Blueprint” Adopted 2001 Member Infrastructure Capacity to participate Data Standards Common way to define shared terms Data Exchange Templates Common way to package shared data Trading Partner Agreement How information flows between partners Exchange Network Components Network Administration Registration, process support, communication Technical Infrastructure Uses standard Internet tools Data Standard s Council, 2000 Network Grants, 2002 Existing Agreements Flow Configuration Document, (FCD) 2004 Node, 2003 New TPAs as needed Governance, evolving over time Schema, 2002

10. 10 Not Just Another Web Site! Can be “built in” to tools you use Send reports—or look it up. Build once, use many times Diminishing cost for new initiatives As protected as the owner chooses Shared Quality Assurance tools—before you try to load Data Standards—shared understanding Discovery Services

11. 11 Finding Data Discovery services let you: –Find out what is on the Network –Learn which partners have nodes –Find out how to access each node and how to request the needed data. –For sensitive data, learn how to obtain permissions for data you have a need to access –If someone has made tools that improve usability of the data, find and use those tools
