1 GEOSS Architecture Implementation Pilot, Phase 3 - Call for Participation - George Percivall, Open Geospatial Consortium GEO Task AR-09-01b Task POC December 2009

2 AIP-3 Call for Participation (CFP) CFP – Main Document –Purpose, Overview, Master Schedule –Instructions on how to respond to CFP AIP Development Process (CFP – Annex A) –Evolutionary Development Process –Roles in AIP –Communications Plan –Principles of Conduct AIP Architecture (CFP – Annex B) –Organized using RM-ODP Viewpoints

3 AIP-3 Summary in CFP Main Document Build on service architecture of GCI and AIP-2 –Build on both content and process –Increase emphasis on data provider point of view –Promote mash-ups in a "link-rich" environment Engage Communities of Practice (CoP)/SBA –Continue AIP-2 CoPs –Identify new CoPs working with UIC and SBA Tasks Focus on data; Promote content –Coordination with ADC Data Tasks –Vocabulary registries and ontologies as resources for scenarios –Data Sharing Guidelines implementation Schedule to support Ministerial Summit, November 2010

DO SCIENCE Submit the paper Minutes Web-based Services: Perform filtering/masking Find data Retrieve high volume data Extract parameters Perform spatial and other subsetting Identify quality and other flags and constraints Develop analysis and visualization Accept/discard/get more data (sat, model, ground-based) Learn formats and develop readers Jan Feb Mar May Jun Apr Pre-Science Days for exploration Use the best data for the final analysis Write the paper Derive conclusions Exploration Use the best data for the final analysis Write the paper Initial Analysis Derive conclusions Submit the paper Jul Aug Sep Oct The Old Way: The SoA Way: Read Data Subset Spatially Filter Quality Reformat Analyze Explore Reproject Visualize Extract Parameter Scientists have more time to do science. Decision makers rapid access to information DO SCIENCE Find Data Courtesy: Gregory Leptoukh, NASA GSFC

14 Data Provider Perspective AIP to increase data access services and to ensure services are correctly registered in the GEOSS CSR Assumptions of Data Provider services 1.Components are deployed as a network accessible services, i.e., have internet address reachable by users 2.Metadata in catalogue includes internet address in on-line linkage 3.Interoperability Arrangement for on-line linkages is supported by Services and Community Clients

17 AIP-3 CFP Information Viewpoint - Draft Spatial Referencing Observations, Sensor Information Geophysical Parameters Maps, features, coverages, and observations Product Types: Global and framework datasets Product Encoding Formats Predictive Models Registry Information Models and Metadata Alerts and Feeds Policy, Rights Management, Licenses

18 Global and Framework datasets for AIP-3 GEOSS 10 Year Plan envisions access to data and information through service interfaces –Move from Order and delivery of files to Access Services GEO Global Datasets Task DA-09-03: –Land Cover; Meteorological and Environmental; Geological; and DEM Promote known global datasets with service access, e.g., –JPL Landsat dataset – OnEarth (300K Maps/day) –CEOS WCS DEM Data Server (ICEDS) –CIESIN socio economic data –(Send link to other global datasets with access services) Link to GEO 2010 Baseline Initiative (Plenary doc 10)

19 Implementation of Data Sharing Principles Handling of Data restrictions –Use small set of controlled terms for data restrictions (drawn from typical licenses) –Define approach for listing data restrictions in metadata (ISO 19115) –Scenario: handling of data restrictions from multiple WMS in Portal. –Scenario (low priority): Rights on web maps created from EO data; WPS –Identify relevant Interoperability arrangements User registration in a system of systems –Several GEO members provide data freely and openly after user registration –Will all GEO users be required to register individually with each GEO member offering data? –Evaluation of alternatives for single-sign in GEOSS context

20 Data definition interoperability a r r a n g e m e n t s Increase dataset definition using interoperability arrangements –Registries and ontologies as resources for scenarios Registries and ontologies for observables –User Requirements Registry –DIAS Definitions –WMO definitions –QA4EO for EO sensor characterizations (Task DA-09-01a)QA4EO –ISO standards for Engineering Use Case for several Enterprise Scenarios/UCs –Client to visualize and relate terms accessed from on-line registries –Enterprise scenario maps terms for discovery (Semantic Mediation)
