•It scales ... to Web-scale
•Doesn t require a super model
•Based on International Data Exchange
Standards (RDF, SPARQL)

Why is RDF important?
• It is an international standard for publishing
data on the Web (public and private)

• Data exchange model

• Serializations include RDF/XML, N-triples,
N3, Turtle, ...

• It is the future of using the Web


Today s data warehouses
• Data warehouse costs are high
• Failure rates are high
• Requires a lot of cooperation ...
• Vocabulary alignment & data harmonization
• Data formats not inter-operable
• Cooperation requires coordination
• 18 months or longer ...


Alternatives include ...
• Use Data Exchange Standards to host
structured content

• Create Linked data warehouses

• Faster & less expensive

• Web architecture, Web-scale

“We really didn’t go into it with any expectations. We
just wanted to see if it was something we might want
to do. That’s why we were caught by surprise by
the results… we weren’t really expecting any.”

-- Jay Myers, Lead Development Engineer, Best Buy

BBC WANTED
The BBC publishes
large amounts of
content online, as
text, audio and video.

As the amount of
content grows, we
need to make it easy
for users to locate
items of interest


"The RDF representations of these web identiﬁers allow
developers to use our data to build applications."

-- Yves Raimond, BBC
