After signing a memorandum of understanding between WMO and OGC a hydrological domain working group has been established. Documents related to its activities are published on OGC Public TWiki.
The Hydro DWG is lead by David Lemon (CSIRO), Ulrich Looser (GDRC) and Ilya Zaslavski (SCDC/CUAHSI) with David Arctur representing the OGC team of directors.
The HydroDWG activities focus on:
- Design of WaterML2.0: feature model, timeseries and observations model by defining a (set of) so-called hydrological profiles for utilizing existing OGC-standards, such as information models (O&M) and service specifications WebFeatureService, WebMappingService, SensorObservationService (v2 under development), WebProcessingService.
- Use case driven Interoperability Experiments to test the design under various (real world) conditions
- Development/harmonization of ontologies/vocabulary or recommended vocabulary references
On behalf of the OpenMI Association, I have presented its history (development and application) as well as the technical details of OpenMI 2.0. Although the number of questions was low, most people seemed to grasp what OpenMI is about. One note to be made is that WaterML2 is much more detailed in data representation, while OpenMI is still relative loose. I have invited people to review OpenMI 2.0, but most likely their review will not meet the deadline of 31/3.
After my presentation, Ann van Griensven informed the group about the work conducted with SWAT, OpenMI and HydroDesktop as well as the challenges for the EnviroGrids projects. Finally, Andrea Rizolli gave his ideas on the future of model integrtion (Similar to his presentation in Brussels).
I have asked David Arctur whether he expected a WebModellingService to arise and where he would expect that OpenMI would fit within the OGC set of standards. David indicated that he expects that OGC will stay at the level of the current services, with the WebProcessingServices being the closest to modelling. he expects that such service would internally use one or more OpenMI components to run e.g. a simulation, but he did not expect that models would/should interact on a timestep level by using OGC-webservices.
The target which David Arctur sees is to make it easy for OpenMI components to be incorporated in an OGC-webservice. For the OpenMI Association this would result in streamlining/harmonizing the OpenMI Standard (with OGC standards) where relevant, supported by implementation guidelines/recommendations for code developers, and possibly some SDK enhancements.
From the OpenMI perspective, another relevant Domain Working Group is Earth System Sciences, lead by Philip Dibner. We will meet him most likely in Ottawa at the iEMSs conference.
