NERC DataGrid - data transfer

  • Focus on large datasets, simple structures

    • Time-series, profiles, gridded datasets

    • Series and collections

  • e.g. Climate Science Modelling Language (CSML)

Fields vs objects

classic geophysics

“Coverage” viewpoint

classic geology

“Feature” viewpoint

Fields vs. objects

  • simple data structures

  • collated/gridded ready for analysis

  • netCDF, HDF-EOS

  • complex data

  • database insertion

  • complete feature interpretations

  • XML documents

Key points
Key Points

  • e-Science depends on

    • Informational Services – to supply modelling constraints

    • Computational Services – to supply simulators and solvers

  • e-Science community focus on “Grid” services

    • high-performance computing, PDE solvers – remote but tight connections

    • large datasets, data warehouses – simple data structures

  • Geospatial community working on REST web-services

    • loosely-coupled, decision-support– on-demand discovery, binding and chaining,

    • detailed semantics – complex data-structures, community schemas
