Astrogrid Ontology Work Meeting

Tony Linde, Antia Richards, Elizabeth Auden, 3 July 2002, University of Leicester

Notes: How to create a grid ontology?

BIG Topics:

  • 1. Position: RA, Dec, time, Solar cords
  • 2. Wavelength: radio, microwave, etc
  • 3. Discipline: radio, solar, high-energy, etc
  • 4. Astronomical objects / events: stars, planets, flares, galaxies
  • 5. Datasets: bibliographies, tables, CCD, etc
  • 6. Time
  • 7. Observational System: satellites, ground-based telescopes
  • 8. Parties: people institutes, projects

CLASS vs PROPERTIES:

  • 1. Subclass of a class usually have additional properties that the superclass does not have
  • 2. Subclass has different restrictions from superclass
  • 3. Subclasses have different relationships than superclasses

MODELS:

Astronomy

  • Wavelength
    • Optical
    • IR
    • X-ray
    • Radio
    • Gamma-ray
  • Dataset
    • Table data
      • Observation logs
      • Extracted properties / catalogues
      • Bibliographies
    • N-Dimension data
      • 1-d: spectra
      • 2-d: CCD image
      • 3-d: RA-Dec-wavelength data
      • n-d: visibility data
