The Web of Things in Practice
This document summarizes a presentation about the Web of Things. It discusses using RESTful approaches and HTTP to integrate physical devices onto the web. Devices could be accessed like web resources through URLs and APIs. This would allow for mashups of physical devices and enable applications to more easily access data from the real world. The presentation evaluated using a web approach versus traditional SOA styles and argued the web style is better suited for Internet of Things applications that need to be ad-hoc and tactical.

Architecture For an Internet of Things, SOA is not always the right approach: The Web of Things alternative seems quite interesting: Good for ad-hoc, tactical applications. Mashup physical devices. Services become a part of the web, of the cloud. Synetgies Zurich, 05.03.2009 Dominique Guinard, ETH Zurich, webofthings.com
