You've probably heard about energy meters that can tweet your electrcity consumption, digital picture frames that can download photos from Flickr, phones that let you track their location on the Internet, and weighing scales that can post your weight on the Web! Clearly, the Internet isn't just a network of computers any more. It is quickly evolving into the Internet of Things.
For the first time ever, more devices than new human subscribers came online with AT&T and Verizon last quarter. This is just the latest data point to validate what many have predicted -- the number of Internet-connected "things" will soon be orders of magnitude larger than the number of users and traditional computers.
-- Erik Wilde, Putting things to REST
The Web of Things is a vision where such everyday objects are seamlessly integrated into the World Wide Web (WWW) using its well-known standards and blueprints, e.g. URIs, HTTP and REST. My colleague,David Simmons, and I offered a hands-on lab titled "Building the Web of Things with Sun SPOTs" at the recently concluded JavaOne 2010 conference. It presents the motivation, key concepts and relevant technologies behind this vision. All of the lab material -- introductory slides (see below), coding exercises and accompanying instructions -- is now available publicly. You may browse it online or download it as a ZIP file.
