What is the exchange network
What is the Exchange Network?

  • A partnership to support better environmental decisions through improved access to, and exchange of, improved environmental information

  • Tools and services that help environmental agency staff integrate, analyze and report data

  • Data and Technology Standards that allow for data to be integrated regardless of the technology

  • More efficient business operations that improves data quality and timeliness

  • Secure data exchanges over the Internet

An Internet and standards-based method for

exchanging environmental information between partners.

How does the en accomplish this
How Does the EN Accomplish This?

  • Collaboration

    • Between EPA and its state, tribal, and territorial partners

    • Between agencies within states

    • Between offices within agencies

  • Technology

  • Shared tools and services

  • Grant Program

    • FY 2002 to present

    • $130M+ in grants to develop infrastructure and flow data

How does it work
How Does it Work?

  • Most Partners have a node

  • A node is a web (Internet) server that responds to requests for information

    • Requests and responses use common formats written is eXtensible Markup Language (XML)

    • Point of Presence through which partners exchange data

  • Nodes use standardized tools and technology neutral components

  • CDX is EPA’s node on the Exchange Network

  • Some partners use node clients

    • Software that is loaded on a desktop computer

    • Limited capabilities

    • Users can submit and request data

    • Does not respond to requests

    • Not automated

    • Less costly and easier to deploy
