  4. Status Update • WP0 • GeoDI Web site: http://geodi.ucc.ie • Reporting: monthly, interim • Liaising with Griffith • Griffith Steering Meeting (02 July 2009) • Internal meetings • Liaising with JuDJuT • 2 internal meetings at CMRC • Recruited 4C postdoctoral researcher for the Ontology Matching position • Generated a book chapter from GeoDI and Griffith deliverables • Chapter: Atlas Interoperability • Book: ICAN Handbook GeoDI Progress Meeting 3

  5. Status Update • WP1 • Finalised D1.1 (Review of Geoscientific Datasets) GeoDI Progress Meeting 3

  6. Status Update • WP2 • Tasks T2.1 – T2.3: Completed • Deliverable D2.1: Review of Ontologies and Controlled Vocabularies • Reviewed by MI, but needs to be finalised • Deliverable D2.2: Identification of Standards and Data Models • Reviewed by MI, but needs to be finalised • Deliverable D2.3: Review on Ontology Languages and Tools • Reviewed by MI, but needs to be finalised • Task T2.4: In progress (80% completed) • Deliverable D2.4: Review of International Best Practice… • Internal review before submission to MI GeoDI Progress Meeting 3

  7. Status Update • WP3 • T3.1 (Integrated Data Models) • Initial data model sent for review by OSU & USGS • Data model based on Arc Marine • T3.4 (Prototype Implementation and Benchmarking) • Installed and tested PostgreSQL/PostGIS • Wrote SQL script for installing Arc Marine (PostgreSQL)  To be published on the Arc Marine web site • Installed Arc Marine on PostGIS GeoDI Progress Meeting 3

  8. Difficulties • Data Modelling • Data complexity (relationships) • Data heterogeneity  Need to design a model that supports all the types of information available in the existing datasets • “Many” options for modelling  Selected option that “makes the most sense” • Domain knowledge  Support from CMRC experts (Max Kozachenko & Gerry Sutton) GeoDI Progress Meeting 3

  9. Deliverables • D1.1: Review of Geoscientific Datasets • Finalised and submitted to MI GeoDI Progress Meeting 3

  10. Deliverables • D2.1: Review of Ontologies and CVs • Content: • Introduction • Introduction to CVs and Ontologies • Existing CVs and Ontologies • GSI, BGS, USGS, NASA, SeaDataNet, etc. • Ontology Use Cases • Interoperability, ETL, Semantic Frameworks • Projects: ICAN, GCMD, OTEG, InterRisk, etc. • Size: 50 pages • Status: • Reviewed by MI (WebEx call) • No major edits required GeoDI Progress Meeting 3

  11. Deliverables • D2.2: Identification of Standards and Data Models • Content: • Introduction • Standards • Organisations: W3C, ISO, OGS, CEN, INSPIRE • Standards: Metadata, Data, Ontologies, Information Exchange • Recommendations • Data Models • Arc Marine, GeoSciML, Arc Geology • Initial Recommendation on Data Model for GeoDI • Size: 30 pages • Status: • Reviewed by MI (WebEx call) • No major edits required GeoDI Progress Meeting 3

  12. Deliverables • D2.3: Review of Ontology Languages and Tools • Content: • Introduction • Introduction to Ontologies • Definition, Semantic Web, Uses of Ontologies • Ontology Languages and Query Languages • RDF, RDF-S, SKOS, OWL, SPARQL, Recommendations • Ontology Tools • Editing, Servers, APIs, Other Tools • Size: 32 pages • Status: • Reviewed by MI (WebEx call) • Need to elaborate more • Need examples from the geoscientific domain GeoDI Progress Meeting 3

  13. Deliverables • D2.4: International Best Practice • Content: • Introduction • Important Developments in the Management of Large Marine Geoscientific Datasets • Bathymetric Attribute Grid, OGC TCWG • Example Projects Showcasing International Best Practice • SIOExplorer, Marine Geoscience Data System • Size: Currently 22 pages • Status: • Under review by CMRC • To add: Chapter on Grid Technology (CMRC) GeoDI Progress Meeting 3

  14. Data Model • Based on Arc Marine • Six packages: • Business Information • Geo Points • Samples • Geo Lines • Measurements • Raster GeoDI Progress Meeting 3

  15. Data Model Arc Marine GeoDI GeoDI Progress Meeting 3

  16. Implementation • Current: • Database implementation on PostgreSQL • Arc Marine implemented • To do: implement the GeoDI model • Load data into the geodatabase • Testing and benchmarking • Future: • Ontology-based automatic or semi- ETL (4C) • Options: • Prototype for a Geo Grid Library (Geo-GLibrary) • Prototype for an ontology based data discovery and delivery system GeoDI Progress Meeting 3

  17. Planning for Next 6 Months • WP2 • Finalise D2.3 & D2.4 • WP3 • Implement data model • Meeting with MI users? • Feed the geodatabase • Validate data model • Start work on automatic ETL tools (4C) • Develop ontologies • Integration of GeoSciML and Arc Marine? GeoDI Progress Meeting 3
