27 June 2013 - The Open Geospatial Consortium (OGC®) announced a call for public comment on the OGC WaterML 2.0 – part 2: Ratings, Gaugings and Sections Discussion Paper. This OGC discussion paper can be downloaded from http://www.opengeospatial.org/standards/dp. This document describes an information model for exchanging rating tables, or rating curves, that are used for the conversion of related hydrological phenomenon (e.g. a stage-discharge relationship). The specification also describes a model for the observations that are used to develop such relationships, often referred to as gaugings, or gauging observations. The information model is proposed as a second part of the OGC WaterML 2.0 suite of standards, building on OGC WaterML 2.0: Part 1, which addresses the exchange of time series data. The following organizations submitted this document to the Open Geospatial Consortium:
Australian Bureau of Meteorology
Centre for Ecology and Hydrology, UK
San Diego Supercomputer Centre, University of California
The joint WMO/OGC Hydrology Domain Working Group will consider all comments when preparing a final draft of the candidate standard. This draft will be used for testing within an upcoming Interoperability Experiment. Interested parties are encouraged to get in contact with the working group. The OGC is an international consortium of more than 480 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.

There are several projects underway or already committed in the OGC related to water resources information systems, and because of the widespread and international nature of these activities it seems like a good time for a general update.
