Linked data :cataloguing and a world wide web of data
UCL Library Services Staff Conference 2014

Thomas Meehan
1. Use URIs as names for things
2. Use HTTP URIs so that people can look up those names.
3. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)
4. Include links to other URIs so that they can discover more things.
Tim Berners-Lee (2006)
