Connecting the Library to the Wider World:
Successful Applications of Linked Data

3. Linked data is not a solution, but a
means towards a solution: start small
• Iterate
• Educate
• Escalate

7. What is Linked Data?
Linked Data is a method of publishing structured data so
that it can become more useful.
At bottom, all data can be expressed as statements of
the form:
<subject> <predicate> <object> .
Example:
Alice has-mother Susan
Alice has-father John
Alice knows Bob
Bob has-mother Martha
Bob has-father Richard
Bob has-birthdate "1994-08-07"
8. Example:
This data can be
visualized as a
connected graph
Alice has-mother Susan
Alice has-father John
Alice knows Bob
Bob has-mother Martha
Bob has-father Richard
bob has-birthdate "1994-08-07"
9. It becomes “linked” data when every entity in the graph
is identified by a URL.
10. To get more information about something, you simply
download a description of that thing from its URL.
For instance, you might download this description of
Alice...
<http://example.com/Alice> :father <http://example.com/John> .
<http://example.com/Alice> :mother <http://example.com/Sue> .
<http://example.com/Alice> :knows <http://example.com/Bob> .
This description contains links to related things. Given
his URL, you can now download information about Bob.
<http://example.com/Bob> :father <http://example.com/Dick> .
<http://example.com/Bob> :mother <http://example.com/Martha> .
<http://example.com/Bob> :birthDate "1994-08-07" .

22. How? Domain driven design.
• A software methodology that bases
complex designs on a model of the
business or organisational domain.
• Initiates a creative collaboration
between technical and domain experts
to iteratively refine a conceptual
model.

23. Evolving Domain Driven Design at Pearson
• How do we capture more structured data
from the editorial process?
• Which is the right data to capture?
• How do we go about maximising the value
of that data?
1: initial simplified model
2: the curriculum ontology
