Panel 3 - Large-Scale Data Management Challenges (bottom-up drivers for infrastructure):

Panel Questions:
  • What technical solutions exist that meet your academic project requirements?
  • What technical solutions exist that meet corporate requirements?
  • What requirements are unique to the academic environment?
  • What requirements are unique to the corporate environment?
  • Are there common approaches for managing large-scale collections?
John Orcutt, Ocean Observatories Initiative [home page]
  • linking observational data and users
  • uses message-based technology - this enables better enforcement of policy
  • uses only cloud services
  • has three components (1) deep sea nodes (2) coastal nodes (3) regional cable network
  • 25 year operational lifetime
  • transformative
  • policy-based data systems
  • rich data and metadata practices
  • scalable architecture
  • both geospatial and temporal enabled

Ed Kearns, National Climatic Data Center [PowerPoint presented by Kenneth Galluppi]


Laurin Herr, Cinegrid [PowerPoint]
  • media convergence motivates CineGrid
  • media technology is driven by 3 sectors - entertainment/media/the arts - science/medicine/education/research - military/intelligence/security/police
  • 35mm is still the standard but digital films may never see this format
  • hollywood studios now facing decisions about what to throw away - eg out-takes
  • use RDF framework for objects
  • use iRODS because of programmable microservices
Philip Maechling, Southern California Earthquake Center [PowerPoint]
  • data is both observational and from simulations
  • the majority of data is from simulations
  • 2-way inter-dependence of data and models
  • computer-generated models should always have associated verified and validated results and code must be included
  • metadata strategies - tools for converting wikis, labels and entries into the metadata store
  • advocates practical metadata standard - should be just enough to go from the data to the results
