1. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Global Water Information Interest Group Welcome to the inaugural meeting GWIIG: https://rd-alliance.org/ig-global-water-information.html (join mailing list)https://rd-alliance.org/ig-global-water-information.html Charter: https://rd-alliance.org/group/global-water-information-interest-group/case-statement/global-water-information-ig-charterhttps://rd-alliance.org/group/global-water-information-interest-group/case-statement/global-water-information-ig-charter

2. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Agenda 1.Introduction to the IG and review of the charter discussion and adoption process 2.Coordination process between GWIIG and OGC/WMO HDWG, and with other groups (all participants) 3.Review of existing water data sharing efforts (in the US, Europe, Asia, other parts of the world: existing standards, experiences and bottlenecks (all participants) 4.Review of water data sharing use cases (all participants) 5.Discussion of WG ideas 6.Summary and consensus (hopefully)

3. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Introduction to the IG Charter formed and adopted following BoF session at RDA P6 Recognising importance of global water data within RDA context Linking work of OGC Hydro Domain Working Group with RDA Linking technical eInfrastructure requirements around water data sharing to work within other RDA groups Benefit from experiences of other domain groups within RDA Provide use cases for both technical aspects and cross-domain data sharing

4. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo GWIIG charter – value proposition (I) a) facilitate dissemination and implementation of water data standards being developed through HDWG activities; b) explore and compare eInfrastructures being developed for water data sharing, with related designs in other domains; c) address issues that are currently outside of the scope of HDWG; d) facilitate re-use of eInfrastructure foundation and components recommended by RDA or developed by RDA partners; e) explore policies for water data sharing as related to the general policy agenda being investigated by RDA groups; f) leverage RDA work on data publication and dynamic data citation (issues directly applicable to management of hydrologic time series); g) make water data sharing a component of global data sharing system within the RDA framework;

5. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo GWIIG charter – value proposition (II) h) gain insights from experience and best practices of data systems in other domains, in particular as they address common pain points in eInfrastructure development; i) coordinate with other RDA groups on addressing common deficiencies of existing data publication and exchange frameworks such as lack of policy level enforcement of a global water data exchange scheme, in the context of each country/continent having its own IT/political approach; j) organize use cases and get feedback from water data users in other domains; k) attract academic researchers working on water data sharing and related infrastructure issues, as their participation may be better recognized and aligned with the RDA framework rather than with OGC; l) widen participation in global water eInfrastructure discussion by attracting members from regions not currently engaged in the development of water data exchange standards through HDWG, in particular from developing countries; m) identify and coordinate requirements relating to water data standards from the wider research community, as input to the HDWG-led standardization process.

6. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo GWIIG charter - participation researchers and developers interested in standards for hydrologic data, mostly representing research staff of water data agencies from multiple countries practitioners responsible for management of water observations, from governments, commercial companies, and public utilities academic researchers interested in various aspects of water data management and sharing hydrologic modelers and forecasters, from academia, government agencies and research centers experts from related domains interested in using water information to support use cases in their domains technical experts and eInfrastructure developers interested in information models, identifier systems, dynamic data referencing, metadata, hydrologic feature and observation semantics and other specifics of water data

7. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Activities and Outcomes – Initial GWIIG focus Use cases related to water data sharing, in particular across different domains Components of eInfrastructure relevant to water information systems Development of more complete information models and ontologies for the water domain Promote water data standards developed within HDWG, explore interoperability with data exchange schemas in other domains, and facilitate global coordination across spatial data infrastructure efforts and stakeholders Integrated data publication and dynamic data citation for water data

8. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Coordination between HydroDWG and RDA Initial point situation Not all people exchanging Water Data fall under OGC types of organisations. The research community is an important community which requirements are not fully addressed. Thus, initial idea was to RDA -> HydroDWG : Enrich HydroDWG use cases and expertise by RDA based contribution HydroDWG -> RDA : In return help raise awareness about HydroDWG standards and outcomes by a better communication towards the research community Links with other groups? Will these come out of Use Cases or do we want to name key international / regional initiatives / organisations?

9. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Types of RDA Outputs Recommendations Flagship outputs Similar in status to OGC specifications; have a defined process for creating and endorsing Supporting Outputs RDA wants to promote them, but these are not necessarily adoptable bridges Upon request, these outputs can go through a community comment period and then get an RDA brand, based on the determination of the Secretariat Other outputs Workshop reports, articles, survey results, etc. (responsibility of the group, no RDA endorsement)

10. Global Water Information Interest Group meeting RDA 7 th Plenary, 1 st March 2016, Tokyo Review of existing water data Use Cases https://docs.google.com/spreadsheets/d/11SgoYYnj1eicvPbUqLENOta2B4zxHyHZ u_CXpGHwIz8/edit?pref=2&pli=1#gid=0 https://docs.google.com/spreadsheets/d/11SgoYYnj1eicvPbUqLENOta2B4zxHyHZ u_CXpGHwIz8/edit?pref=2&pli=1#gid=0 Let’s avoid a discussion of what a use case is, and a use case template There are also RDA working groups: https://rd-alliance.org/groups/working-groups Brief presentations: David Arctur Jesus Marco de Lucas Ilya Zaslavsky – on behalf of Hydroshare, CINERGI and CZO Discussion of dynamic data citation – WG outputs Questions: Further examples from the meeting Where is the best place to list these? How to proceed, promote, populate further? How are we going to use it?
