Service oriented architecture for sharing water data
The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) is an organization representing 120+ universities in the US and 11 international affiliates. As
CUAHSI member universities in the US
CUAHSI HIS develops service-oriented architecture for hydrologic research and education, to enable publication, discovery, retrieval, analysis and integration of hydrologic data. The project team has defined a common information model for organizing hydrologic observation data, designed a common exchange protocol (Water Markup Language), created a collection of SOAP web services (WaterOneFlow services) that provide uniform access to different federal, state and local hydrologic data repositories, and developed mechanisms for ontology-based data registration and discovery.

HIS Central
This system is implemented as a collection of HIS Servers deployed at NSF-supported Hydrologic Observatory test beds across the nation. Several HIS Server are deployed at other partner universities and agencies, and internationally.
CUAHSI HIS supports data publication workflow for hydrologic observations. The steps include:• Loading data into ODM instance
and configuring a Generic ODM web service providing access to the data (typical for relatively small academic projects) OR
Configuring a custom WaterML-compliant web service and assembling a source metadata catalog (typical for large remote repositories)• Registering the new water data
service at a local HIS Server (to be accessible via DASH, Data Access System for Hydrology), AND/OR
Registering the service at the HIS Central, a web application for managing and exploring WaterML-compliant services.
By indexing both government and academic water data services, HISCentral provides a gateway to the largest collection of water observations in the nation.
Once a new water data service is registered, tested and described at HISCentral, an HISCentral’s harvester retrieves site and variable metadata, and the data series information.

The next step is tagging the harvested variables using CUAHSI ontology concepts, and making the new water data service appear in Hydroseek, a web application for ontology-based and map-based search and retrieval of hydrologic data from multiple networks.
