PIOTRe: Personal Internet of Things Repository.

Resource-constrained Internet of Things (IoT) devices like Raspberry Pisu0027, with specific performance optimisation, can serve as interoperable personal Linked Data repositories for IoT applications. In this demo paper we describe PIOTRe, a personal datastore that utilises our sparql2sql query translation technology on Pisu0027 to process, store and publish IoT time-series historical data and streams. We demonstrate with PIOTRe in a smart home scenario: a real-time dashboard that utilises RDF stream processing, a set of descriptive analytics visualisations on historical data, a framework for registering stream queries within a local network and a means of sharing metadata globally with HyperCat and Web Observatories.
