The Web of Things (WoT) architecture recently proposed by the W3C working group constitutes a promising approach to handle interoperability issues among heterogeneous devices and platforms, by semantically describing interfaces and interaction patterns among the Things.

The WOT STORE allows users to perform semantic discovery of the available Things, to search for compatible applications available on the market, and to install them over the target devices, all within the same framework.

Abstract

The Web of Things (WoT) architecture recently proposed by the W3C working group constitutes a promising approach to handle interoperability issues among heterogeneous devices and platforms, by semantically describing interfaces and interaction patterns among the Things. One of the main advantage of the W3C architecture is the possibility to decouple the description of the Things' behavior from their implementation and communication strategies, hence greatly simplifying the deployment of novel applications and services on top of it. Starting from such state-of-art, and envisioning a Web of seamlessly interacting W3C Things, this paper focuses on the next steps, i.e.: how to effectively support the discovery of Things? and: how to ease the distribution of applications running on Things? We answer to both the questions above through the proposal of the WOT STORE, a novel software platform supporting the distribution, discovery and installation of applications for the W3C WoT. The WOT STORE allows users to perform semantic discovery of the available Things, to search for compatible applications available on the market, and to install them over the target devices, all within the same framework. We describe the platform architecture and its proof-of-concept implementation, providing two alternative interfaces to interact with our tool: a Web portal, and new modules developed for the popular Node,-RED platform. Finally, we discuss two realistic use-cases of the WOT STORE for industrial IoT and home automation systems, remarking theadvantages of our solution in terms of deployment costs and interoperability support.
