Ideas from previous presentations

• EuroSpec

• From user requirements to quality requirements
• Accreditation
• Common procedures
• Organize feedback complaints

More ideas

• Language of complaints language of quality
  reports?
• What is the benefit for a producer to include
  reliable data quality results in metadata
• Metadata are not understood by users
• Tools that give advice to end users (or auditors)
• Is the quality of this dataset suitable for my
  needs
• From quality elements to usability
• Tools for the quality auditor?
• Respositories of earlier auditor results
  (usability gradings)?
• Nominal uses (reference services)?
