Presentation given at the Dev8d Developer Days event at the University of London Students Union, London, UK on 15th February 2011. The talk was primarily aimed at developers with the assumption that they knew a bit about RDF and Linked Data, so it doesn’t discuss these except in passing. I was mainly trying to give some specifics on the technicalities involved, and what platforms and tools we’re using, so people can follow the same path if they wanted.
