Further Challenges
• Identity
• Metadata is most useful when linked to user data, which implies identity
• Need a standard for federated identity / federated user profile
• This standard needs to be aligned with other industry metadata efforts
• Privacy
• Who gets to see my profile?
• Data protection rules differ depending on location and jurisdiction
• If I’m advertising that I’m a child whenever I make an HTTP request from my phone, does
that make me safer or less safe?
• Standardized metadata vocabularies also required
• Ok – we agree what an “music artist name” is, but what do I call Prince?
