What is the Exchange Network?
An Internet and standards-based method for
exchanging environmental information between
partners.
4
Purpose of Network

• Support automated exchange of data
• Enable timely and accurate exchange
• Reduce reporting burden
• Improve data quality

5
What is a Network Node ?

• A simple environmental information Web service
  that initiates requests for information,
  processes authorized queries, and sends/receives
  the requested information in a standard format.

Nodes (Web Service)

• A Node
• Is a Server accessible by the www
• Complies with the protocols to ensure secure
  exchange
• Returns requested information as XML
• Each partner has only one Node

8
The old medium for exchange flat files

• A simple way to share data
• Cannot be validated without custom software
• Very hard to read
• Cannot accommodate complex data in one file
• Simple but messy

9
XML

• XML Schema
• Describe format of data being exchanged
• Draw upon data standards
• Potential to reuse XML schema modules

10
XML in a nutshell

• XML eXtensible Markup Language
• XML Schema defines the Structure and the Rules
  of data to be shared
• XML Document a file that contains the data (and
  references the Schema)
• Create an XML document, open it with Internet
  Explorer and it validates itself against the
  schema

11
XML is not a silver bullet

• Agreement on the definition of data is still the
  same old challenge
• XML is a new skill
• XML is verbose

The Main Act

• Cradle to Grave Shipments
• of Hazardous Waste

24
Data Request

• Node A Hey, what Treatment Facilities can
  receive waste over there?
• Data Service GetLegalTreatmentFacilities
