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

•Standardized metadata vocabularies also required
•Ok – we agree what an “music artist name” is, but what do I call Prince?
