What dimensions of quality should be considered?
- Quality control
- Error bar
- Missing data
- Contamination (weather, clouds)
- Instrument error
- Cross instrument consistency
- Quality assurance (someone tags it as valid)
- Useful metadata provided?
- Subjective scaling (e.g. quality judgement with range 0-5)
- Instrument Verification and Validation
- Data processing
- What common data quality standards can the Federation offer within the Earth Information Exchange?
- What 3rd party ratings can we support?
- NCDC Certified data (only states that it is in the archive)
- DIF records have some minimum required fields to accept; then have a text field to describe quality
- Maturity Model approach for data (John Bates)
- How can we enforce these standards within the Earth Information Exchange?
- Are there similar ratings for "data services"?
