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 usesthe Document Object Model(DOM)to representcomplex physical environments, with a CSS-like syntax for storingand 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 implementationand explore some ofthe many potential avenues for future research. These include rich WoT development tools and the possibility of content production for physical environments
