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

Actors

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

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 – On. Earth (300 K 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)

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

Data definition interoperability arrangements • 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 – QA 4 EO for EO sensor characterizations (Task DA-09 -01 a) – ISO 19100 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)
