OGC ® HIC 2014 Tutorial: Proposed agenda: Water Markup Language 2.0 – Part I (Time Series) Rating and Gaugings, or WaterML 2.0 Part II. Standard representation and encoding of hydrologic features Standard representation and encoding of hydrogeologic features Hydrology profile of the OGC Sensor Observation Service Standards ‐ based service ‐ oriented architecture models and brokering for hydrology Standards ‐ based water data catalogues. Federating regional and national water data providers: the GEOSS model Modeling and encoding of water quality information, and hydrologic and hydrogeologic vocabularies

OGC ® Modelling and encoding of groundwater observations and features Interoperability experiments and pilots in water data exchange: past, ongoing and planned Existing WaterML 2.0 implementations in commercial and open source software Efforts of US, European and Australian government agencies, and WMO, in offering standards based data access Future of water data exchange standards: What is missing in the current suite of standards? What is needed most? What are additional use cases to consider? HIC 2014 Tutorial: Proposed agenda: continued

OGC ® Copyright © 2014 Open Geospatial Consortium Motion: as BP Motion: “OGC Sensor Observation Service 2.0 Hydrology Profile ” as BP The Hydrology DWG recommends that the OGC Technical Committee approve release of r1 “OGC Sensor Observation Service 2.0 Hydrology Profile ” as an OGC Best Practice Document –Pending and final edits and review by OGC staff –Motion: –Second: –There was no objection to unanimous consent This document is intended to describe a best practice how the SOS 2.0 standard can be applied to server WaterML 2.0 encoded hydrological observations in an interoperable manner.

OGC ® Copyright © 2014 Open Geospatial Consortium Motion: as ER Motion: “OWS-10 CCI Hydro Model Interoperability Engineering Report” as ER The Hydrology DWG recommends that the OGC Technical Committee approve release of “OWS-10 CCI Hydro Model Interoperability Engineering Report” as an OGC Engineering Report –Pending and final edits and review by OGC staff –Motion: –Second: –There was no objection to unanimous consent This OGC® document gives guidelines for enabling interoperability among different hydro data models and services. The demonstration specifically gives out best practices for supporting interoperability among the National Hydrographic Network (NHN) of Canada, the National Hydrographic Dataset Plus (NHD+) of United States, and the OGC HY_Features model developed and proposed by the World Meteorological Organization (WMO). The discussed version of OGC HY_Features was adopted as the mediation bridge model to exchange information among heterogeneous hydrological models.
