URIs and RDF."





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!


Sounds great. What’s the catch?


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


Not applications on the web, but of the web.


I want my data!


I want your data, my way!


A practical use case


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...


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


purlz.org


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...

Linked Data Communities


Libraries Role

• Credibility Commons

• problem for documents

• even more so with data

• “Trusted” Views


Recommended Next Steps

•Trusted identifiers to invest in

•example - id.lcsh.info

•subjects, places, languages, people, etc.

•Shape enabling infrastructure

•purlz.org


Recommended Next Steps

•Continue discussion around libraries role in Linked Data

•ROI, best practices, lessons learned

•shared, enabling infrastructure

•credibility

•vocabularies


Linked Data is hereCan you afford not to be part of it?


thank you
