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’

Raw data now!

Tuesday, July 21, 2009

Sounds great. What’s the catch?

Tuesday, July 21, 2009

It takes the big step of fundamentally rethinking applications and their integration

Tuesday, July 21, 2009

Not applications on the web, but of the web.

A practical use case

Tuesday, July 21, 2009

The Library of CongressDigital 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...

Tuesday, July 21, 2009

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

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...

Libraries Role

• Credibility Commons

• problem for documents

• even more so with data

• “Trusted” Views

Tuesday, July 21, 2009

Recommended Next Steps

•Trusted identifiers to invest in

•example - id.lcsh.info

•subjects, places, languages, people, etc.

•Shape enabling infrastructure

•purlz.org

Tuesday, July 21, 2009

Recommended Next Steps

•Continue discussion around libraries role in Linked Data

•ROI, best practices, lessons learned

•shared, enabling infrastructure

•credibility

•vocabularies
