AIP Architecture Elements

• Components – Manageable units hardware, software, networks

• Services– Methods for components to interact using GEOSS

Interoperability Arrangements • Use Cases

– Describe what can be done with Services, e.g., Discovery, Access, Workflow, etc.

• Scenarios – Meet SBA User needs;

accomplished with Use Cases

Additional Technical topics in AIP-3

• Semantics• Web Processing Services• Uncertainty handling• Data Harmonization• Data Sharing Guidelines

Need for CoP Integrator role

Semantics applied to Water in GEOSSGEO Tasks: Semantics, DIAS, AIP

• Ontology Engineering

• Integration of independent thesauri that are sharing the same data format, SKOS

• Integrate 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 ontology

– using the CMap2 visual tool.

– OWL ontology for grounding broker's search

Data Sharing in AIP-3

• Primary focus on handling licensing.– Licensing framework suggested by Harlan Onsrud, et. al.:

“Towards Voluntary Interoperable Open Access Licenses for GEOSS”

– Framework focused on open access licenses, and used Creative Commons framework as a working foundation

• Secondary focus on user registration and login.– Many data sets and repositories require user authentication

prior to data access– DSGWG looked at single-sign-on (SSO) as a federated

solution and as a centralized solution

The « Data Harmonization » topic

• GEO Task AR-09-01b (AIP)– Emergence of Data Harmonization topic, pilot and input for

the GEO Task DA-09-01b– Emphasis on Data Quality and Uncertainty Management

• GEO Task DA-09-01b – Data, Metadata and Products Harmonization

• Other GEO Tasks (Data Integration, Global Datasets…)• INSPIRE 2010 Conference and Workshops

– Numerous sessions with Data Harmonization topic• OGC

– A cross-WG topic : SensorML, O&M, GML, WCS…– Could be similar to OWS for service interfaces– Could reach out the Data Quality SWG

Successful Implementations for SBAs using GEOSS Interoperability Arrangements

• GEOSS bold vision endorsed 5 years ago

• Architecture vision now realized for several societal applications

• Get involved: GEOSS ADC, SIF, AIP, CoPs
