At the Web 2.0 Expo conference, there was a lot of talk this week about sensors, data, and the Internet of Things, and very little about “Web 3.0” or the Semantic Web. I asked Tim O’Reilly about the relationship between Internet of Things and the Semantic Web as  we walked from the Moscone Center to the Marriott. This was one of the questions on my CS 299 final exam, so it was good to hear Tim’s perspective.
