Health Datapalooza IV: June 3rd-4th, 2013
Linked Data – Structured Data on the Web
Moderator:
David Wood, Chief Technology Officer, 3 Round Stones
Speaker:
Bernadette Hyland, Chief Executive Officer, 3 Round Stones
Linked Data is a standards-driven model for representing structured data on the Web that gives developers, publishers, and information architects a consistent, predictable way to publish, merge and consume data. Find out what Linked Data is all about from Bernadette Hyland and David Wood from 3 Round Stones, who will present the Linked Data mode in plain, jargon-free language while provide an example of how Linked Data is being used by Sentara Healthcare to combine authoritative open government data with user entered information to providing personalized guidance for patients suffering from asthma, diabetes and heart disease.

19. Summary of Problems
• How can we archive our data in an open
manner?
• How can we record data context?
• How can we record data provenance?
• How can we know whether our data is up
to date?
• How can we share our data with others?
21. Linked Data
• Provides an international standard
mechanism to put reusable data on the
World Wide Web
• Provides a single data model with
multiple formats
• Provides context, provenance and access
• Allows for both human and machine reuse
22. Linked Data Principles
• Name data files and elements with URIs
• Use HTTP URIs so people can resolve them
on the Web
• Provide useful information at those URIs, using
the standards (RDF, SPARQL)
• Include links to other URIs so people can
discover more information.
