The Sharing of water data across disparate computer hardware and software platforms is facilitated by the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Hydrological Information System (HIS) and similar open and closed source systems. CUAHSI’s WaterOneFlow (WoF) and WaterML 1.1 web services and data encoding standard have become widely recognized and implemented. This growth in demand for and use of standards for water data sharing has prompted the Open Geospatial Consortium (OGC), a major international standards setting organization, to promulgate a more widely applicable data-encoding standard called, WaterML2. This paper presents a generic OGC standards-based water data sharing approach using WaterML2 and the existing OGC standard for vector data encoding, Web Feature Service (WFS). A data sharing system built using these two standards has the benefit of being accessible by a much broader collection of software systems than previously available using WoF and WaterML1.1. The new approach requires encoding of data sites in a WFS accessible layer that includes attributes that identify a WaterML2 encoded data set available at each site. The system is prototyped in the open source HydroServer Lite data server. This service-oriented architecture completes an essential link between two major standards in geospatial and temporal data management and sharing.
