We’ll discover how publishing can enhance the profile of environmental information.

Future of publishing

PNW WQX, completed early 2005, demonstrated the feasibility of many important EN concepts.

The hybrid centralized/decentralized approach includes data submission and publishing flows

Instead of sending the same old oversized query response, optimize your publishing schema with

Data discovery and query costing can be built in to the data flow.

6
One way to enhance data discovery is to implement nested queries.
Providing Organization
Project
Monitoring Station
Field Event
Result
Sample Analysis
GetProjects
GetStations
GetMeasurements

A Data Catalog can provide summary information for the sources underlying the flow.
7
Station lists classified by station type can allow customers to geographically focus queries.

8
Data Catalog services can tell the customer what data they might find at a particular location.

Data Catalog services can also provide data for query costing purposes.
Customer enters search parameters
GetDCReferenceDataCount
Query/solicit using these parameters is first sent to Data Catalog
Your query may return up to 29,763 results.
Do you wish to continue?

Estimated size of response returned
GetMeasurements
“Continue” routes query/solicit to nodes(s); other options reduce node server loading

The future of EN data publishing includes more, varied data partners and applications.

Parties other than EPA and ECOS should be at the table to increase partners within EN.
11
As node technology improves, opportunities for data publishing rather than transmission improve.

12
Data publishing will help us connect EN data with other types of data and other networks

Applications consume “our” info via web services, adding value and support.

EPA Region 10’s STORET.org consumes Stations

Applications are being developed to consume, warehouse and analyze specific data.
14
Beyond charting, QC and statistical analysis tools could also be developed.

In summary, data publishing builds partnerships with other providers and environmental information clientele.
Enhanced data partnerships mean greater data availability.
More data means more incentive to build value-adding tools.
More network tools mean more customers and greater support.
