This document summarizes a demo of using SPARQLstream and Morphstreams to visualize transport data from Madrid's public transport company (EMT) in a tablet application. EMT provides real-time bus arrival times as XML streams. The demo transforms this data into RDF streams using the SSN ontology, defines R2RML mappings, and queries the streams using SPARQLstream. A Map4RDF iOS app then retrieves bus stop data and waiting times to display on a map. The demo shows how to publish open transport data following web standards to enable integration and mobile applications.
