  1. OOI Cyberinfrastructure and Semantics OOI CI Architecture & Design TeamUCSD/Calit2 Ocean Observing Systems Semantic InteroperabilityWorkshop, November 18 2008

  2. Outline • OOI Overview • Cyberinfrastructure Project Plan • Scientific Investigation Scenario • Data Collection Workflow • Data Management Services • Technologies

  3. OOI Overview

  4. Cyberinfrastructure Project Plan • Current status: Past FDR; prototyping in pilot period; construction planned for 7/2010 • Spiral development process, five releases, six subsystems • OOI observatories: Coastal, Global, Regional • External observatories: IOOS, Neptune CA, VENUS, …

  5. Science Activity Model Scientific Investigation

  6. Data Processing and Availability

  7. Subsystem • Dynamic Data and Information Distribution • Common data and metadata model • Stream and message based data distribution network (publish/subscribe) • Efficient dataset wire transport • Data/information catalog and repository • Persistent archive • Data Integration • Real-time QA/QC’ed data from OOI observatories • External observatory and dataset integration

  8. Subsystem • Data and Information Access • Public data access in various syntactical formats • Flexible search and navigation • Faceted queries using ontologies • Transformation and Mediation • Syntactical transformation (in and out of the DDN) • Aggregation of datasets • Attribution and association • Semantic mediation using ontologies/vocabularies • Manage provenance, lineage and policy

  9. Transformation Service Data Model • Relationship between the constituents of the Transformation Service and the Information Container Model

  10. Technology Mapping

  11. Summary • NSF’s OOI CI Goals • Build the next generation cyber-infrastructure for ocean research, education and public participation • Timeline • Prototyping ongoing • OOI construction planned for 7/2010 to 6/2015 • Semantics • Ontology based query and mediation • Success depends on the integration of MMI vocabularies and semantic framework, the VSTO semantic framework and faceted search

  13. Information Container Model • Encapsulates all kinds of information resources, such as: scientific data, user identities, process definitions, virtual machine images, etc. • Multiple levels of meta-data • Separation of concerns between Information services

  14. Ingestion • Provides basic mechanisms for identifying the data streams and formats, parsing the content and identifying the associated meta-data, adding version information, and registering the streams with a ISN Repository

  15. Ingestion Service Data Model • Relationship between the constituents of the Ingestion Service and the Information Container Model
