16. Linked Data Principals
• URIs for ‘things’
• people, places, concepts, etc.
• Use HTTP URIs to make data most accessible
• When serving URIs, deliver useful / reusable
information
• leverage standards (RDF, SKOS, SPARQL)
• Add context / relationships between ‘things’

32. The Library of Congress
Digital Preservation
• 180+ Partners
• Located across the globe
• Groups have different charters, goals, budgets
• Many of these groups would benefit from sharing
and connecting their data
• But it exists in many disconnected silos...

33. What’s the Answer?
• Empower users to create their own views of
data to satisfy different job roles and changing
needs
• Build a community around the data in which
users help each other to curate and connect as
needed
• Skip the supermodel - Leave data in the
multiple “best of breed” systems; wrap and
expose using the Web as a platform

57. Linked Data Communities
Enhancing access:
• Easy to expose collections via the Web
Connecting islands of information:
• Collections available from one access point
• Access and connect data across multiple
collections
Creating and preserving the community:
• Share best practices across communities
• Establish a network of trust and participation
Open data opens new doors...

61. Libraries Role
• Credibility Commons
• problem for documents
• even more so with data

• example - id.lcsh.info
• subjects, places, languages, people, etc.
• Shape enabling infrastructure
• purlz.org

63. Recommended
Next Steps
• Continue discussion around libraries role in
Linked Data
• ROI, best practices, lessons learned
• shared, enabling infrastructure
• credibility
• vocabularies
