17. Why Linked Open Data?
•
It’s cool
•
“Increase and Diffusion of Knowledge”
•
Share, contribute to a global database
•
Create context around data
•
Allow data to be reused/repurposed by
creators and a worldwide community
•
Improve discoverability of content

18. So Just what is Linked Data
•
Publishing structured data on the web
•
RDF (Resource Description Framework)
•
Enables queries computer 2 computer
•
uses standard ontologies (vocabularies)
•
data in “triples” (“triplestore”)

20. Linked Data Design Issues
“The Semantic Web isn’t just about putting data on the web. It is
about making links, so that a person or machine can explore the
web of data. With linked data, when you have some of it, you can
find other, related, data.”
Tim Berners-Lee, Linked Data – Design Issues
1. Use URIs as names for things.
2. Use HTTP URIs so people can look up those things.
3. When someone looks up a URI, provide useful
information, using the standards (RDF, SPARQL).
4. Include links to other URIs, so they can discover more
things.

21. * On the web, open
** Machine-readable data
*** Non-Propriety format
**** RDF Standards

22. DBpedia is a community effort to extract structured
information from Wikipedia and to make this information
available on the Web. DBpedia allows you to ask
sophisticated queries against Wikipedia, and to link other
data sets on the Web to Wikipedia data.

23. The three sides of the tri-color cube in these logos evoke
the triplet of the RDF model. The peeled back lid invites
you to Open Your Data to the Semantic Web!
