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
