A presentation to Digital Sparks North West's Transmissions event on 21 July 2010 [http://transmission6.eventbrite.com/].

This presentation covers Linked Data and the Semantic Web, and uses the example of companies such as TripIt to demonstrate that a little semantics can go a long way. The presentation then explores more formal approaches, such as those underway within the UK Government, and asks whether or not this is feasible in a commercial context.
