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
AIP-3 Summary and Recommendations

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
GEOSS Information framework
GEOSS SoA Information Viewpoint
AIP-3 Summary and Recommendations
• Improved decision-making
– Coordinated SBA and technical developments
• Improved access to variety of observations
– Remote sensing, in-situ sensing, & models
• Repeatable results through engineering process
– Scenarios, Services, Interoperability Arrangments
• Increased capabilities through web services
– Access, Processing, Data, Semantics
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
