IG Global Water Information - RDA 11th Plenary meeting


Meeting title

Joint working session of the Global Water Information Interest Group and the OGC/WMO Hydrology Domain Working Group (Remote Access Instructions)

Collaborative session notes: 


Short introduction describing the activities and the scope of the group

The Global Water Information Interest Group (GWIIG) enables communication among RDA WGs and IGs focused on both technical eInfrastructure aspects (e.g. brokering; metadata and catalogs, dynamic data citation) and on related research domains (e.g. geosciences, agriculture, biodiversity) that are pertinent to water and water data. The group also provides a coordination mechanism across a wide group of water information stakeholders, in particular those not previously involved in the efforts of the active OGC/WMO Hydrology group on water data standardization. Recent and current areas of interest are: 
• Dynamic data citation in water
• Vocabularies in water, particularly for freshwater quality measurements
• Water data discovery and water data portals
• Water data rescue

Meeting objectives

The meeting is planned as a joint session between RDA GWIIG and OGC/WMO HDWG. The main goal is to discuss themes of mutual interest for both groups, and align activities/roadmaps and communication/update mechanisms. A joint session is desirable because OGC Technical Committee meeting is being held in Orleans during the RDA Plenary in Berlin. Such a session is only possible if it is scheduled in the afternoon of Wednesday March 21st. Ideally, it would take place during the breakout group session slot on the first afternoon of the RDA Plenary. At OGC TC, it will be a group session slot on the last afternoon before the OGC Thursday Plenary. Securing this spot early is important as the timing needs to be coordinated with organizers of both meetings. The group will physically meet in Orleans, and a web connection to the session will be open to RDA attendees in Berlin, as well as to other remote participants.

The mutual topics of interest include: 
• Standard representation and navigation of linked features and their observations: presentation of results of OGC ELFIE (Environmental Linked Features Interoperability Experiment)
• Presentation and discussion of water data portals compendiums from RDA GWIIG, from the perspective of OGC WaterML2 standards support
• Synergies and coordination between OGC/WMO HDWG and RDA GWIIG, identifying joint priorities and coordination roadmap
• Review of RDA outcomes and their relevance to water data exchange standardization work at OGC HDWG
