2 A process, elaboration of GEOSS Architecture SBA Tasks,UIC, CBC,STCUserNeeds,ScenariosrequirementsDesign,Develop,DeployADC activitiesincluding:ArchitectureImplementationPilot (AIP)Task AR-09-01bsupportOperationalCapabilityGEOSS CommonInfrastructure (GCI)Task AR-09-01apersistentimplementationOf particular interest for the GMES data products :- Data Sharing Principles, Quality Assurance for Earth Observations, SIF convergence guidelines and practices- Long Term Data Preservation- Risk Management, disaster/failure recovery2
3 GEOSS Interoperability Arrangements - From the GEOSS 10 Year Plan Reference Document - Interoperability through open interfacesInteroperability specifications agreed to among contributing systemsAccess to data and information through service interfacesOpen standards and intellectual property rightsGEOSS adopting standards; agreed upon by consensus, preference to formal international standardsGEOSS will not require commercial or proprietary standardsMultiple software implementations compliant with the open standards should existGoal is that at least one of the implementations should be available to all implementers "royalty-free"
4 GEO Task AR-09-01b Architecture Implementation Pilot Support SBAs by developing new process and infrastructure components for GCI and the broader GEOSS architectureDemonstrate and document results to inform GEOSS Development Baseline progress“fostering interoperability arrangements and common practices for GEOSS”Consistent with that, Task AR 09-01b is defined as: highlighting the development and testing of contributed components and leveraging of the GEOSS Common Infrastructure in a pilot setting exercising interoperability arrangements to serve SBAs/CoPs

9 Drought Scenario and Use Cases (simplified) Reference: “Global Drought Monitoring Service through the GEOSS Architecture”, Drought and Water Working Group, Engineering Report, GEO AIP-3, February 2011
10 European Drought Observatory use of EuroGEOSS Contact: Stefano Nativi
14 Semantics applied to Water in GEOSS GEO Tasks: Semantics, DIAS, AIP Ontology EngineeringIntegration of independent thesauri that are sharing the same data format, SKOSIntegrate more general ontologies created with primitives in schema languages (e.g. SWEET)AIP-3 development of an ontology of water-related terms, based on CUAHSI ontologyusing the CMap2 visual tool.OWL ontology for grounding broker's search
16 Semantic Enabled Search Use Case GI-DAC broker implemented Semantic Search UCLeverages GENESIS vocabulary service for generating multiple, multilingual queries to be issued to remote catalogs.Multi-lingual searching: Language-dependent search patterns against language-neutral URIs.“Advanced search” allows user to navigate thesauri, define a set of terms and queries to catalogs.
20 GEOSS AIP Phase 4 (AIP-4)Activity #1: Access to Priority EO Data Sources1a. Thesaurus for EO Observation Parameters1b. "EO Priority Data Sources” list1c. Getting EO Data OnlineActivity #2: Clients and Mediated Access Enablers2a. Coordination with GCI2b. Coordination of Enabler Components2c. Integration and Usability Testing of Enablers ComponentsAIP-4 CFP responses requested by 6 May 2011Supporting ADC “Sprint to Plenary”
21 Water Information Services with GEOSS Interoperability Arrangements GEOSS bold vision endorsed 5 years agoArchitecture vision now realized for several societal applicationsGet involved: GEOSS ADC, SIF, AIP, CoPsA short video is being developed for use at the ministerial in November.
