Advancing Oceanographic Research through Innovative Cyberinfrastructure Design

This document outlines the Ocean Observing Initiative (OOI) Cyberinfrastructure architecture and design, presented during the Semantic Interoperability Workshop on November 18, 2008. It details project plans, current status, and technological developments aimed at enhancing scientific investigations in oceanography. Key components include dynamic data distribution, data integration systems, and semantic mediation for efficient data access and preservation. Drawing from collaborations with external observatories, this initiative strives to build a next-generation framework for ocean research, education, and public engagement.

  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
