Why Everything Will

Keep Changing

John Graybeal, MBARI

about me
About Me
  • 19 years at NASA, 4 years at MBARI
  • Led data team (3 yrs), data projects (4 yrs)
  • Principal Investigator, Marine Metadata Interoperability (http://marinemetadata.org)
  • ORION Cyberinfrastructure Committee
the situation
The Situation
  • Ocean.US / IOOS
  • ORION / OOI
  • NEPTUNE, PIONEER
  • MARS, VENUS
the schedule
The Schedule
  • 2005
    • MARS (starts)
    • IOOS (planning)
  • 2006
    • MARS (continues)
    • OOI (starts?)
    • IOOS (kind of starts?)
  • 2007
    • OOI (starts)
    • IOOS (starts?)
  • 2008
    • OOI (continues)
    • IOOS (continues?)
the data
The Data
  • Regular observations (think meteorology)
  • Model outputs (think outputs)
  • Observing campaigns
  • Irregular data sets
data repositories
Data Repositories
  • Big centralized archives
  • Domain-specific collections
  • Observatory records
  • Local data sets (accessible or otherwise)
data access overview
Data Access (Overview)
  • Call someone and ask them to send it
  • Call someone to find out where it is
  • Use a catalog (GCMD, OPeNDAP, …)
  • Use Google
data access detailed
Data Access (Detailed)
  • FTP or download (in standard format?)
  • DODS/OPeNDAP (gridded data)
  • Live Access Server (files and plots)
  • Web Services (think http on steroids)
data access examples
Data Access Examples
  • LOBO: Web interface to a data set
  • AOSN: Web (LAS) interface to a collection
  • SSDS: Web services to a repository
  • MMI: Web services to multiple repositories
what will drive change
What Will Drive Change
  • Increase Access: More data sets
  • Decrease Access: Security
  • Automate Access: Workflow
  • Smarter Access: Semantic Awareness
what will change
What Will Change
  • Available data sets (but not often)
  • Locations of data
  • Interfaces to find and access data
  • Applications to work with data
so for curricula what then
So (for curricula), What, Then?
  • Expect dynamic interfaces
  • Assume (define?) required expertise
  • Design curricula around basic data sets
  • Look for structural commitments to data
