Project Description This project is the web services and the central catalog for the CUAHSI Hydrologic Information System (HIS) is an internet-based system for sharing hydrologic data. See http://his.cuahsi.org/ for details.

The component of HIS are:

• HIS Central (THIS PROJECT) — contains copies of metadata which facilitates searches; works like a search engine, in that it harvests metadata from the data servers and allows it to be efficiently searched by the clients.
• HydroServer — stores, organizes and publishes data; allows metadata to be harvested by HIS Central and data to be shared with clients.
• Clients (such as HydroDesktop) — gives users a convenient interface to access data; retrieves metadata from HIS Central and retrieves data from HydroServers.

In addition, this project will contains the base code for the Web Services. We will be requesting the code examples/donations from the existing community of developers for more examples.
