1 Water Data in the Unified Modeling Language Xitian Cai Center for Research in Water Resources The University of Texas at Austin

2 CUAHSI-HIS Status Facilitate better interoperability and promote better dissemination, understanding and collaboration between water data users Make possible access to hydrological data sets by other interested domains OGC Hydrology working group; World Meteorological Organization (WMO) An international standard UML

3 WaterML Locations Variable Codes Date Ranges GetSiteInfo GetVariableInfo GetValues WaterOneFlow Web Service Client STORET NAM NWIS Data Repositories Data EXTRACT TRANSFORM LOAD WaterML WaterML is an XML language for communicating water data (Maidment, 2007)

4 eXtensible Markup Language (XML) XML was designed to transport and store data Environmental Markup Language (EML) Earth Science Markup Language (ESML) Mathematical Markup Language (MathML) Field Data Markup Language (FDML) Geography Markup Language (GML)
