6. Co-operation Service Exploitation Service Providers Service Consumers SSE High-level Requirements • Provide an environment • With common approach for online and offline services • Improving cost efficiency • Reducing time to provide / demonstrate new services • Neutrally managed • Empower Service Providers in • Orchestrating EO / GIS services from own and partner service elements • Maintaining full control over own infrastructure and IPR

7. User Portal Requests Directories Workflows Service A - Service A • Service B • Service C • … A1 A2 Info A3 On-line / Off-line Results Internet Toolbox Toolbox Service Provider 1 Service Provider 2 Service Provider 3 On-line / Off-line Results SSE Architecture • Service publication, chaining, fruition • On-line / off-line services • Services remain at providers’ facilities • Data exchanges outside Portal

8. Service Chaining Example User need: NPP* (service) over Belgium (AOI) in GeoTIFF (format) SSE Portal Workflow: Net Primary Productivity S1 S2 S3 NPP Processor(VITO) Format Conversion (GIM) Clipping Service (GIM) NPP EuropeHDF NPP EuropeGeoTIFF NPP BelgiumGeoTIFF Spot Végétation S10 (*) NPP or Net Primary Productivity represents repeatable estimates of the net flux of carbon

9. Service Provider • Enters in partnership with other Service Providers • Orchestrates the supply chain defining services … • Publishes “his” services from own and partners’ infrastructure(maintaining full control over it) • Authorises users to activate “his” services • Monitors “his” service execution status, on the SSE Portal workflow and on his infrastructure • Is responsible for • Defining and publishing “his” own SLA • Monitoring and respecting “his” QoS • Invoicing (if applicable)

10. TOOLBOX • Allows easy service “publishing” • Provides a generic gateway towards service providers’ infrastructure (e.g. DBMS, File System) • Supports even services with NO infrastructure behind • Interface towards the Service Provider infrastructure based on widely accepted IT standards • Permits to translate local terms into SSE ones (no need to change Service Provider infrastructure)

11. Service Orchestration • Workflow editor to chain services ...

12. Service Orchestration Workflow console to monitor service instances

13. 1 - select service category 2 - define interaction methods 3 - describe the service 4 - here the technicalities 5 - register! Service Definition Panel

14. User Interactions • Select service of interest • Identify time and AOI (selection method chosen by Service Provider) • Select parameters (e.g. format) • Get RFQ (if applicable) • Issue order / request • Check status of orders / requests • Get the output (delivery options identified by Service Provider)

15. Selection of Time, AOI, Parameters

16. Check status of orders / requests

17. Get results (service output)

18. Table of Contents • Background • Implementation • Standards • Demonstrator • Conclusions

19. Web services • WSDL file provided by service provider • XML schema for each service • document-style SOAP • ws-addressing (W3C) for asynchronous communication • BPEL (OASIS) for service orchestration

21. ws-inspection • Service discovery from "BPEL Designer"

22. WS-Interoperability (ws-i.org) • Request/Response (synchronous) • Basic callback (asynchronous)

23. OGC Standards • GML for AOI encoding • GML for service results

24. OGC Standards • WMS - superimpose layers and service results • Web Map Context - to save displayed map layers ERS SAR catalogue Envisat ASAR catalogue RadarSat catalogue Wave height & direction model Ship detection processor ERS SAR online data access O il spill detection processor ERS SAR online data access

25. OGC Standards • WMS: Catalogue search results can be shown on map • Web Map Context: allow to save/load context

26. Catalogue Acces • Currently ESA EOLI-XML ICD (SOAP): Search/Present • Migration to OGC Catalog 2.0 (CSW) being investigated. • Data distribution mechanisms • FTP/HTTP : URL passed in SOAP message • WFS - to publish service results (vector data) • WCS - as alternative data distribution mechanism

27. Gazetteer (Alexandria) - to select rectangular AOI

28. Gazetteer (Alexandria) to select circular AOI

29. Other Web standards • XSLT - presentation service results • RSS - publication of news items • XHTML - to support mobile devices (planned) • CSS - separation style and content • SVG - number of catalogue images available per day/month/year. • RDF/RDFS - find services via ontology (prototype)

37. Conclusions • The SSE empowers Service Providers with capabilities to • Dramatically reduce integration, test and demonstration costs • Promote own services maintaining control on infrastructure and IPR • Re-use, combine and chain services within the supply chain • Concentrate resources on core business and added value • Ease working relationships (basic cooperation environment) • The SSE empowers users with • Simplified selection and activation of services • Selection of services closer to own expectations • More coherent contacts with service providers • The SSE provides feedback on: • Integration of wide range of heterogeneous EO/GIS services including catalogues • Requirements and possible evolution

38. Future Work • SSE as playground for GS Coordinationto consolidate ongoing activities on Interface Control Documents’ definition for GS Modules • Follow on of institutional cooperation and international forumscoordination with IPs in Risk Management (DG INFSO),cooperation with EC on INSPIRE and OGC, … • Extract and consolidate requirements from relevant programmes GMES, GSE, … • SSE technological enhancements (next 3 years)including convergence with Grid technology and evolution of standards, …

39. Support, suggestions, feedback welcome for: • Promotion / awareness vs. Service Providers • Cooperation opportunities Thank you !
