A Dynamic Hierarchical Approach to Modelling and Orchestrating the Web of Things Using the DOM, CSS and JavaScript

There is a lot of work in progress by the W3C and others surrounding a Web standards compliant Web of Things (WoT) which it is hoped will unify the current Internet of Things infrastructure. Our contribution to this uses the Document Object Model (DOM) to represent complex physical environments, with a CSS-like syntax for storing and controlling the state of 'things' within it. We describe how JavaScript can be used in conjunction with these to create an approach which is familiar to Web developers and may help them to transition more smoothly into WoT development. We share our implementation and explore some of the many potential avenues for future research. These include rich WoT development tools and the possibility of content production for physical environments.
