external observatory integration subsystem purpose
External Observatory Integration Subsystem: Purpose

The External Observatory Integration (EOI) subsystem:

  • integrates external observatories (i.e. IOOS) with the OOI Integrated Observatory
  • facilitates inclusion of external data
  • delivers data in community specific forms
  • allows immediate full scale testing of the OOI-CI System
  • introduces OOI to a community of early adopters
release 1 product description use case overview
Release 1 Product Description Use Case Overview

EOI provides support for a number of the R1 Use Cases:

  • Hello Data Source – Data source is registered and connected
  • Ingest and Describe Data – Externally provided data read and distributed
  • Merge Data – Provide data unified from many sources
  • Present as Catalog – present organized set of resources externally
  • Put to External Repository – Send data to repository outside the system
  • Version A Resource – Resource is supplanted by changed version
architectural overview
Architectural Overview
  • EOI exists under the auspices of an Instrument within the OOI-CI System
  • It is responsible for translating data between external forms and the internal OOI-CI canonical form

status of progress
Status of Progress
  • Established the Rutgers modeling team as the initial scientific “client”
  • Started developing interaction patterns between OOI-CI, IOOS, & Scientists
  • Compiled lists of data sources, outputs and workflows required by the Rutgers modeling team
status of progress cont
Status of Progress (cont.)

Current Status of Rutgers Data Sources

  • Data Types:
      • SSH, Forcing, Salinity, Temperature, Rivers
  • Providers:
      • PFEG, Rutgers, NAVY, USGS, RADS, NCEP, AOML
  • Acquisition Forms:
      • NetCDF, ASCII
  • Acquisition Protocols:
      • OPeNDAP, curl, wget, urlread
  • Prospective CDM Types:
      • Grid, Station, Trajectory, Profile
technology challenges and achievements
Technology Challenges and Achievements
  • Achievements:
    • functional prototypes of NetCDF  DAP translation in both JAVA & Python
  • Challenges:
    • compatibility of DAP libraries in Java and Python
plan for elaboration
Plan for Elaboration
  • Continue to work with selected scientific modeling groups
  • Register each data source as a Provider in the OOI-CI System
      • Translation/transformation to achieve CDM/CF compliance
      • Leverage IOOS data sources wherever possible
  • Work with scientists to utilize the OOI-CI System for acquiring data
  • Provide client with a tool for OOI-CI syndication notifications
significant risks
Significant Risks
  • IOOS Interoperability
      • Establish liaisons with IOOS integrator
      • Initiate collaborations with IOOS
      • Start IOOS integration activity as an EOI
  • Model Integration Strategy
      • Early and ongoing involvement of modeling community in design process
      • Early prototyping of data sharing between models and control of ensembles of models
