The WaterML 2.0 Part 1: Time Series Encoding Standard has been adopted by the Open Geospatial Consortium as an OGC standard. OGC WaterML 2.0 is XML-based and supports encoding and exchanging hydrological data describing the state and location of water resources, both surface water and ground water.
WaterML 2.0 is designed to provide a standard for national reporting of water resources as well as for operational echange of data on the state of infrastructure such as water supply systems. Much of the work was done as part of a joint program between the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) and the Australian Bureau of Meteorology (BoM).
The standard is important in Australia because it will be used in the development of the second version of the Water Data Transfer Format (WDTF) which mandates the techniques to be used by the Australian water industry to deliver water data measurements to the Bureau of Meteorology as required under the Water Regulations of 2008.
The Australian effort was supported by the Consortium of Universities for the Advancement of Hydrologic Science Hydrologic Information System (CUAHSI), which developed WaterML 1.0, and other organizations in the Netherlands, Germany, Canada, France, and the U.S including NOAA and USGS.
