IFLA 2010 has come and gone. Although I did not go, the presentations are now online, and some are outstanding. Richard Wallis, Technology Evangelist from Talis, had a very interesting take on the semantic web. It's quite the package, with 194 slides altogether. Wallis' presentation examines some of the innovative examples of open data that such companies as the BBC is already experimenting with. Wallis argues that if libraries are to participate in the Semantic Web, MARC records will need to be the first type of library data to be shared with the open web concept.
