Max Craglia (JRC) and Stefano Nativi (CNR) FP7-ENV-2011 Planning Meeting 24 September 2010, GEO Secretariat Outcome of EuroGEOSS Multi-disciplinary Interoperability: the EuroGEOSS Operating Capacities
2
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Outline EuroGEOSS introduction Present GCI shortcomings for SBAs The EuroGEOSS approach/capacities –Multi-disciplinary Interoperability –Mediation and Brokering framework Conclusions
3
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Three Interoperability phases
4
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Present GCI shortcomings for SBAs High Entry Barrier –SBAs need to “learn” and develop many IT technologies –which are changing.. –It is difficult to “evaluate” and “use” discovered resources Limited functionalities –Only register and discovery functionalities are implemented –no access and use –Discovery: no distributed query (only harvesting) Limited multi-disciplinary interoperability –Main issues: resources heterogeneity, domain semantics, resources chaining Limited to “traditional” geospatial resources –No “community” resources –No complex resources –workflow, environmental models, thesauri, etc. –No Web 2.0 resources Limited sustainability –Limited scalability: a flat approach to interconnect resources is not sustainable when you have hundreds of thousands of (heterogeneous) entries –Limited flexibility: what about future: systems, specifications, capacities ?
5
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 EuroGEOSS principles system of systemsImplement a “system of systems” –Consisting of existing and future information systems –Supplementing but not supplanting systems mandates and governance arrangements –Shift from technical interoperability towards conceptual composability existing (autonomous) Resources Interoperability StandardsBuild on existing (autonomous) Resources and Interoperability Standards RegisterRegister existing thematic components, services, and interoperability standards Assure Low Entry Barrier for SBAs (both Users and Providers) MediateMediate (Community standards and capacities) BrokerBroker (harmonize providers heterogeneity and distribute functionalities
6
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Low Entry Barrier for SBAs The EuroGEOSS multi-disciplinary infrastructure must –implement all the necessary mediation and brokering functionalities to interoperate with SBA systems –Implement necessary semantic services to facilitate multi- disciplinary interoperability SBAs (and CoPs) systems –Remain autonomous –Remain unchanged –no new standard must be implemented, no new component or service must be implemented or deployed SBAs (and CoPs) must use their own standards to: –describe available spatial resources –publish accessible resources

8
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Sustainable development For complex (large and heterogeneous) infrastructures, SOA archetype does not scale and is not flexible enough A Brokered-SOA proved to be: –more sustainable (i.e. flexible and scalable) (tens of thousands) Service Provider Service Provider Service Provider Service Provider Service Provider Service Provider Service Provider Service Provider Server Service Consumer Service Consumer Client Service Registry Service Registry Publish Find (Harvest) Bind Present GCI framewok (hundreds)

10
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 A Brokering Framework (interoperability arrangements) EuroGEOSS has developed a Brokering Framework for discovery, access, semantics –OGC/ISO Resources e.g. WMS, WFS, WCS, CSW, WPS, etc. –Community Resources e.g. GBIF, CDI, THREDDS/OPeNDAP, GDACS, DIF, netCDF, etc. –Web 2.0 Resources e.g. OpenSearch, GeoRSS, OAI-PMH, Flickr, Twitter, Myspace, Wikipedia, etc –Semantic resources Thesauri (GEMET, SBA categories, etc.)
11
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Use cases EuroGEOSS multi-disciplinary infrastructure is successfully used for a couple of AIP-3 scenarios –Biodiversity & Climate Change WG e-Habitat & Species Occurrences Use Scenarioe-Habitat & Species Occurrences Use Scenario –A web based decision-making tool for assessing environmental changes due to anthropogenic activities, including climate change –The development of the modeling web service for computing habitat similarities and irreplaceability allows the community to assess possible environmental consequences. –Water (Drought) WG European Drought Observatory (EDO) Use ScenarioEuropean Drought Observatory (EDO) Use Scenario –Assessment of the drought situation in Europe –Multi-scale approach based on subsidiarity that integrates drought information from various scales

FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Conclusions EuroGEOSS addresses most of the Interoperability gaps and challenges recognized at the ADC workshop ( Ankara 2010) –Support different levels of interoperability Intra-disciplinary and cross-disciplinary –Support Interoperability standards heterogeneity Adopt international standards and Recognize community standards –Support resources heterogeneity Data, services, processing models, workflows, feeds, thesauri, documents, etc. Extend the SOA architecture –Support advanced functionalities Discover, evaluate, access, use, – transform, harmonize, chain, etc.

FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Thank you for your attention !
17
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 Proposed Contributions 1) Continuity with what has been done already in EuroGEOSS = brokering + semantic searching + access to data across 3 themes (no reinventing the wheel) 2) Extend to the other SBAs (THREDDS) + other mediating services to link to what they have already 3) Support more and more access and use of data cross themes for real analysis 4) Support models and data sharing
18
FP7-ENV-2011 Planning Meeting– Geneve, 27 Sept 2010 System of Systems approach conceptual composabilityShift from technical interoperability towards conceptual composability interoperability arrangements –by recognizing and specifying interoperability arrangements low entry-level-barrier resource Users ProducersAssure a low entry-level-barrier for both resource Users and Producers existing infrastructures heterogeneous resourcesBuild incrementally on existing infrastructures (information systems) and incorporate heterogeneous resources distribution and mediation functionalities brokering frameworksIntroduce distribution and mediation functionalities (i.e. brokering frameworks) for heterogeneous resources Discovery, access, processing and chaining
