What is the Exchange Network Browser?
• National Tool for Accessing Data on the Exchange Network
• Integrated with Exchange Network Discovery Service (ENDS)
• Interacts with and retrieves data from publishing Nodes (Query / Solicit)
• Retrieved data (XML) can be: Transformed (HTML, CSV, etc) for easier viewing
Geocoded and mapped
Plotted on graphs
Features of EN Browser
• Public access & secure (NAAS) access
• Node and Data Service Health Check
• Data Discovery - ENDS / DEDL Integration:
• ENDS (describes services):
• Node info, basic service info (name, parameter listing)
• DEDL (further describes service parameters):
• Labels, Required Y/N, Multi-Select, Pick Lists (can be static or dynamic)
• Geospatial-based querying (using publish WMS/WFS map services)
• Data Retrieval - Advanced Solicit Handling and History
• Personal Data Library – Supports many different flows
• Data Analysis:
• Mapping (including geocoding data without lat/long)
• Charting (Time Series, Bar Chart, Bivariate scatter plot)
• Open Source Solution

Closing Thoughts
• Universal tool:
• Can work with any existing or future published data flows
• Promotes Data Publishing Best Practices:
• So data isn’t just published but well-described
• Needs Content:
• Will rely on data publishers to take advantage of features
• Value will increase over time as more data is published
• Meta Data to describe data set with disclaimers?
• Stylesheet Library to promote reuse?
