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 ?


EuroGEOSS principles• Implement a “system of systemssystem 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

• Build on existing (autonomous) Resources existing (autonomous) Resources and Interoperability Standards 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


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

Complexity to manage




Sustainable development• For complex (large and heterogeneous) infrastructures, SOA

archetype does not scale and is not flexible enough• A Brokered-SOA proved to be:

A sustainable approach

A sustainable approach


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.)


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

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.


Thank you for your attention !Thank you for your attention !


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


System of Systems approach• Shift from technical interoperability towards conceptual conceptual

composabilitycomposability – by recognizing and specifying interoperability arrangementsinteroperability arrangements

• Assure a low entry-level-barrier low entry-level-barrier for both resource Users resource Users and ProducersProducers

• Build incrementally on existing infrastructuresexisting infrastructures (information systems) and incorporate heterogeneous resourcesheterogeneous resources• Introduce distribution and mediation functionalitiesdistribution and mediation functionalities (i.e.

brokering frameworksbrokering frameworks) for heterogeneous resources• Discovery, access, processing and chaining
