“... FAO’sprinciple task is to
 work to ensure that the
 world’s knowledge of food
 and agriculture is available
 to those who need it when
 they need it and in a form
 which they can access and
 use ...”

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.

A big cloud! But how much linked?
“Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/”




        http://aims.fao.org      johannes keizer
Do libraries
have a
specific role?
..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
