beneficial aspects of the historical format.
• Basis for community discussion / dialog
• Produce prototypes and tools to enable testing and evaluation
• Create a roadmap for moving forward toward refinement,
redevelopment or alternative approaches

• Mid-May/June
• Analysis of related initiatives
• Initial draft of Linked Data model
• July/August
• Prototype and translation services

8. Linked Data
"a term used to describe a recommended best
practice for exposing, sharing, and
connecting pieces of data, information,
and knowledge on the Semantic Web using
URIs and RDF."

9. The Power of
Recombinant Data
Friday, September 7, 2012

10. Libraries and Linked Data
• Increased flexibility for describing resources
• More reusable links from one record to another
• New options to contextualize external sources
• Ease of integration of catalogues into general
purpose Web and social media
• Lightweight model easier to extend for future needs
• Facilitate re-use of data and ability for developers to
incorporate into other apps
• Improved positioning of credible records from
libraries within Web search engines

14. Analysis Process
Deconstruct MARC
• Identify Resources reflected
in MARC records
• Core vocabularies associated
with these MARC Resources
• Types, People, Places,
Organization, Topics, etc.
• Provide the building blocks
for communities to connect,
re-assemble as needed

23. Analysis Process
Supporting Code
• Prototype and translation services
• Mechanism for validating the model
• Shared tooling, experiences to accelerate
adoption
Friday, September 7, 2012

24. Criteria for Success
“A Seat at the Table”
• Common ground for accelerating the
conversation
• Draft of a code model, serialization,
supporting code that provide such a table
• Semantic building blocks that enableand relate
communities to connect, re-assemble,
to as needed
• Process and procedure for supporting
community dialog and evolution
