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?
