6. Tim Berners Lee at TED 2009 on Linked Data
 All kinds of conceptual things, they have names now
that start with HTTP.
 I get important information back. I will get back some
data in a standard format which is kind of useful data
that somebody might like to know about that
thing, about that event.
 I get back that information it's not just got somebody's
height and weight and when they were born, it's got
relationships. And when it has
relationships, whenever it expresses a relationship
then the other thing that it's related to is given one of
those names that starts with HTTP.

9. Do libraries
have a
specific role?

10. ..yes, very much
 We have tons of structured and semi -
structured information in bibliographical
databases
 Many of these bibliographical records are
using some standard vocabularies, i.e.
• AGROVOC: 300 to 1000 data sets all over the world
• CABI: at least 100?
• NALT: some 100s in the USA
• LCSH: enormous numbers of bib. Databases
 One vocabulary catches multiple datasets
