, 6. Standards
• Ideally, metadata structures and definitions should be
referenced to a standard
• As standards become adopted within the wider

assist the industry in implementing the standard
• Without standardization, meaningful comparisons are

many metadata management styles
• the problem has been that there are a number of
"standards" in use or development
